[0045] FIGS. 1-3 represent various views of an embodiment of a device 31 that includes an axial field rotational energy device (AFRED). Depending on the application, device 31 may include a motor that converts electrical energy to mechanical energy, or a generator that converts mechanical energy to electrical energy. I. PANELS
[0046] Embodiments of device 31 may include at least one rotor 33 with a rotation axis 35 and a magnet (i.e., at least one magnet 37). A plurality of magnets 37 are shown in the embodiment of FIG. 3. Each magnet 37 can include at least one magnetic pole.
[0047] The device 31 can also include a stator 41 that is coaxial with the rotor 33. The rotor 33 can be coupled to an axis 43 and with other components, such as one or more of the following items: a mounting plate, fastener , washer, bearing, spacer or alignment element. Embodiments of stator 41 can include a single unit panel, such as the printed circuit board (PCI) 45 shown in FIG. 4. PCI 45 can include at least one layer of PCI 47. For example, certain embodiments described here include twelve layers of PCI 47. The layers of PCI 47 can be parallel and are spaced in the axial direction. Each layer of PCI 47 can include at least one conductor track 49. Each track 49 is a separate conductor entity formed on a given layer of PCI 47. For example, eight tracks 49 are shown in FIG. 4. Tracks 49 can be configured in a desired pattern, such as the coils illustrated in FIG. 4.
[0048] FIG. 4 depicts the embodiment of a layer of PCI 47 within a PCI of twelve layers 45. The other eleven layers of PCI are similar, with differences described below in relation to the subsequent figures. In the illustrated PCI layer 47, each track 49 (forming a single coil) includes a first terminal 51 on the outer edge of the coil, and a second terminal 53 in the center of the coil. Tracks 49 are connected to other tracks 49 using tracks 55. A first set of tracks 55 is positioned adjacent to the first terminal 51 on the outer edge of each coil, and a second set of tracks 55 is positioned adjacent to the second terminal in the center of each coil. In this embodiment, tracks 49 on the illustrated PCI layer 47 are not directly connected to an adjacent track 49 on this illustrated PCI layer 47, but are directly connected to a corresponding track 49 on another layer of PCI 47, as explained in more detail. with reference to FIG. 5 and FIGS. 6A-6D.
[0049] In this embodiment, each track 49 is continuous and uninterrupted from its first terminal 51 to its second terminal 53, and connections to that track 49 are made only to the first and second terminals 51, 53. No tracks 49 includes other terminals for electrical connections. In other words, each track 49 can be uninterruptedly continuous without other electrical connections, including the absence of additional pathways 55, between the first and second terminals 51, 53. Also shown in FIG. 4, the width of a given track 49 may not be uniform. For example, the width 171 corresponding to an outer corner of the track may be greater than the width 173 corresponding to an inner corner of the track. The spacing 175 between adjacent concentric track portions forming a single coil can be the same or different from the spacing 177 between adjacent tracks (i.e., different coils). In some embodiments, a given track may include a width in the outer region that is adjacent to an outer diameter of the PCI and in a plane that is perpendicular to axis 35, and a width in the inner region that is adjacent to an inner diameter of the PCI PCI and plan. In some embodiments, the width in the outer region may be greater than the width in the inner region. In some embodiments, a given track may include opposite internal and external extremes that are not parallel to each other.
[0050] FIG. 5 depicts the embodiment of a twelve-layer PCI 45 incorporating the PCI layer 47 shown in FIG. 4. Each of the twelve layers of PCI 47 are closely spaced and form a "sandwich" of layers of PCI 47, identified as 47.1-12. In the upper layer of PCI 47.1, a first track 49.11 (also described here as "coil 49.11") is shown, whose first terminal 51.1 is coupled to an external terminal 61 for device 31. In the lower layer of PCI 47.12, a track 49.128, whose first terminal 51.12 is coupled to an external terminal 63 for device 31. In this embodiment, there are eight tracks 49 (coils) in each of the twelve layers of PCI 47.1-12. These tracks are coupled (as described in more detail below) in such a way that the current flow will enter through the external terminal 61 will flow through the ninety-six coils, then it will exit through the external terminal 63 (or vice versa it will enter through the external terminal 63 and will exit via the external terminal 61). In this embodiment, only one track 49 (e.g., coil 49.11) is attached to the outer terminal 61 for device 31, and only one track 49 (e.g., coil 49.128) is attached to outer terminal 63 for device 31. For an engine, both external terminals 61, 63 are input terminals, and for a generator, both external terminals 61, 63 are output terminals. As can be seen in this embodiment, each PCI layer includes a plurality of coils that are coplanar and angularly and symmetrically spaced from each other around the axis, and the coils in adjacent PCI layers, in the axial direction, are circumferentially aligned to each other. with the others around the axis to define symmetrical coil stacks in the axial direction.
[0051] FIG. 6A is an exploded view of a part of the twelve-layer PCI 45 shown in FIG. 5, which is labeled to better illustrate how the coils are coupled via routes 55, 59, and thus better illustrate how the current flows to the outer terminal 61, through the ninety-six coils, then flows out of the outer terminal 63. Suppose that the input current 81.1 flows to the external terminal 61. This current flows "in a spiral" through the coil 49.11 (in the PCI layer 47.1) as current 81.2 and 81.3, and arrives at the second terminal 53 of the coil 49.11. Track 55.1 connects the second terminal 53 of the coil 49.11 to the second terminal of the corresponding coil 49.21 on layer 47.2 of the printed circuit board directly below the coil 49.11. Thus, the current flows through 55.1 as current 81.4, then flows in a spiral through coil 49.21 as current 81.5 until it reaches the first terminal 51 for coil 49.21. Track 55.2 connects the first terminal 51 of the coil 49.21 to the first terminal of the coil 49.12 in the PCI layer 47.1, adjacent to the first coil 49.11. In this embodiment, tracks 49 on the first layer of PCI 47.1 are generally inverted (mirror image) in relation to those on the second layer of PCI 47.2, so that track 55.1 overlaps with both "tabs" on the second terminal 53 of coils 49.11 and 49.21, and also so that track 55.2 overlaps with both "flaps" on the first terminal 51 of coils 49.12 and 49.21, as described in more detail below in relation to the following figures. Thus, the current passes through 55.2 as current 82.1 to the first terminal 51 of the coil 49.12 in the printed circuit layer 47.1.
[0052] From this terminal, current flows through coils 49.12 and 49.22 in a similar manner to that described for coils 49.11 and 49.21. For example, current flows around coil 49.21 (in PCI layer 47.1) as current 82.2 and 82.3 for second terminal 53 of coil 49.21, flows through 55.3 as current 82.4 for second terminal 53 of coil 49.22, then flows as chain 82.5 and 82.6 around coil 49.22 until it reaches the first terminal 51 of coil 49.22. As before, a track 55.4 couples the first terminal 51 of the coil 49.22 to the first terminal 51 of the coil 49.13 on the PCI layer 47.1, which is next to the coil 49.12. This coupling configuration is replicated for all remaining tracks 49 on the two layers of PCI 47.1, 47.2 above, and current flows through these remaining tracks 49 until it reaches the last coil 49.28 on layer 47.2 of the printed circuit board. The current, having already passed through all sixteen coils on the top two layers of PCI 47.1, 47.2, is now directed to the next layer of PCI 47.3. Specifically, a path 59.1 couples the first terminal 51 of the coil 49.28 to the first terminal of the coil 49.31 on the PCI layer 47.3, which is directly below the coils 49.11 and 49.21. In this embodiment there is only one coil in layer 47.2 of PCI for one coil in layer 47.3 of PCI through a coupling of 59. Conversely, there are fifteen of these pathways, 55 coupling coils in layers of PCI 47.1, 47.2. In this embodiment, such coupling occurs only at the first and second terminals 51, 53 of the coils.
[0053] Paths 55 between the third and fourth layers of PCI 47.3, 47.4 are configured in the same way as the paths between the first and second layers of PCI 47.1, 47.2 described above and, therefore, the configuration of the path and the flow of corresponding current need not be repeated. This continues to descend through the PCI "sandwich" layer until it reaches the lowest layer of PCI 47.12 (not shown here). As described above, the first terminal 51 for the track (coil) 49.128 is coupled to the external terminal 63. Consequently, the current that flows in through the external terminal 61, after passing through all 96 coils, flows out through the terminal external 63.
[0054] FIG. 6B is an enlarged view of a group of tracks 55 shown in FIG. 5. This track group is adjacent to the respective second terminal 53 for each of a group of vertically aligned coils 49.1-12 on each of the twelve layers of PCI 47.1-12. As mentioned above, tracks 49 on the second layer of PCI 47.2 are generally inverted (mirror image) in relation to those on the first layer of PCI 47.1, so that track 55 overlaps with both "tabs" on the respective second terminal 53 of these vertically adjacent coils. As shown in FIG. 6B, on coil 49.18 (first layer, eighth coil) the second terminal 53.18 includes a flap that extends to the side of the track. In the form of a mirror image, on coil 49.28 (second layer, eighth coil) the second terminal 53.28 includes a flap that extends in the opposite direction to the side of the track, so that these two flaps overlap. Track 55 connects these two overlapping flaps. Likewise, since the embodiment shown includes 12 layers of PCI 47, each of the five additional lanes 55, respectively, overlapping terminals 53.38 and 53.48, overlapping terminals 53.58 and 53.68, overlapping terminals 53.78 and 53.88, terminal 53.98 and 53,108 overlapping and 53,118 and 53,128 overlapping terminals.
[0055] FIG. 6C shows two of these pathways 55 in an exploded format. The terminal 53.38 of the coil 49.38 overlaps the terminal 53.48 of the coil 49.48, and they are coupled by a first way 55. The terminal 53.58 of the coil 49.58 overlaps the terminal 53.68 of the coil 49.68 and are coupled by a second way 55. As can be Clearly appreciated in the figures, these pairs of overlapping flaps, together with their corresponding pathways 55, are scaled in a radial direction so that these pathways 55 can be implemented using coated through-hole paths. Alternatively, these roads can be implemented as buried roads, in which case the roads do not need to be staggered, but can be aligned vertically.
[0056] FIG. 6D is an enlarged view of a group of pathways 59 also shown in FIG. 5. In this embodiment, these pathways 59 are positioned in the spacing between a specific adjacent pair of vertically aligned coils 49 (for example, between coils of the highest layer 49.11 and 49.18), while pathways 55 are positioned in the other spacing between other pairs adjacent to vertically aligned coils 49. In this figure, tracks 59 are shown as coated through-hole tracks. Tracks 55, 59 overlap with both "tabs" on the respective first terminal 51 of the corresponding coils. Paths 55 couple horizontally adjacent coils in vertically adjacent layers, while pathways 59 couple horizontally aligned coils in vertically adjacent layers, as shown in FIG. 6th for both. There are only five lanes 59 shown in this embodiment because the first terminal 51 on the upper coil 49.11 is coupled to the outer terminal 61, and the first terminal 51 of the coil 49.128 on the lower layer of PCI 47.12 is coupled to the outer terminal 63, leaving only 10 PCI layers (47,211) with coils whose respective first terminals 51 are coupled in pairs. For example, the innermost path 59.5 couples a respective coil in the PCI 47.10 layer to a respective coil in the PCI 47.11 layer.
[0057] In various embodiments, each track 49 can be electrically coupled to another track 49 with at least one track 55. In the example of FIG. 6A, each layer of PCI 47 has eight tracks 49 and only one track 55 between tracks 49. In some embodiments, each track 49 is electrically coupled to another track 49. Together, two tracks 49 define a pair of tracks 57. In FIG. 7, there are twelve layers of PCI 47.1-12, and there are six pairs of tracks 57.1-6.
[0058] Each pair of tracks 57 can be electrically coupled to another pair of tracks 57 with at least one other track 59 (eg, only one track 59). In some versions, tracks 49 (eg, coils) on each pair of tracks 57 (eg, pair of coils) may be located on different layers of PCI 47, as shown in FIG. 6A. In other versions, however, tracks 49 in each pair of tracks 57 can be coplanar and located on the same layer of PCI 47.
[0059] In some embodiments, at least two of tracks 49 (for example, coils) are electrically coupled in series. In other models, at least two of tracks 49 (eg, coils) are electrically coupled in parallel. In still other versions, at least two of the tracks 49 are electrically coupled in parallel and at least two other tracks 49 are electrically coupled in series.
[0060] Embodiments of device 31 may include at least two of the pairs of tracks 57 electrically coupled in parallel. In other versions, at least two of the track pairs 57 are electrically coupled in series. In still other versions, at least two of the pairs of tracks 57 are electrically coupled in parallel and at least two other pairs of tracks 57 are electrically coupled in series.
[0061] As illustrated in FIGS. 4 and 6, each layer of PCI 47 (only the top layer PCI 47 is shown in the top views) comprises a surface area of the PCI layer (LSA) which is the total surface area (TSA) of the entire surface (top ) of PCI 45. TSA does not include holes in PCI 45, such as the center hole and the mounting holes shown. The one or more tracks 49 (eight coils shown in FIG. 4) on layer 47 of the PCI may include a coil surface area (CSA). CSA includes the total footprints of the coils (i.e., within their perimeters), not just their "copper surface". The CSA can be in a range of at least 50% of the surface area of the PCI layer, such as, for example, at least approximately 55%, at least approximately 60%, at least approximately 65%, at least approximately 70% at least approximately 75%, at least approximately 80%, at least approximately 85%, at least approximately 90%, at least approximately 95%, at least approximately 97%, or even approximately 99% of the surface area of the PCI layer . In other embodiments, the surface area of the coils may be not more than 99% of the surface area of the PCI layer, such as not more than approximately 95%, not more than approximately 90%, not more than approximately 85%, not more than approximately 80%, not more than approximately 75%, or even not more than approximately 70% of the surface area of the PCI layer. In other embodiments, the surface area of the coils may be in the range between any of these values.
[0062] The CSA can also be calculated in relation to any sensors or circuits (such as IOT elements) on or in the PCI. The elements of the IOT may be limited to no more than 50% of the TSA. In addition, the elements of the IOT can be incorporated into the CSA or incorporated into at least part of the TSA that is not included in the CSA.
[0063] The total area of each track that forms a coil (that is, including the conductor tracks, but not necessarily including the spaces between the conductor tracks) can be considered as a surface area of the coil. The performance of the device 31 is believed to be improved by increasing the surface area of the aggregate coil, in relation to the surface area of the underlying PCI layer in which the coil (s) is formed.
[0064] In some embodiments (FIG. 4), the device 31 may include a stator 41 that comprises a single electrical phase. The stator 41 versions can consist of a single electrical phase. Each layer of PCI 47 can contain a plurality of coils that are coplanar and symmetrically spaced from each other around axis 35 (FIGS. 2 and 3). In one example, each coil consists of a single electrical phase.
[0065] FIG. 8 represents an embodiment of stator 41 including at least two electrical phases (for example, three phases indicated). Each layer of PCI 47 can include a plurality of coils (such as tracks 49) as shown for each electrical phase. For example, FIG. 8 illustrates coils corresponding to three phases A, B and C. The coils for each electrical phase A, B and C can be moved angularly from each other around axis 35 (FIGS. 2 and 3) within each layer of PCI 47 to define a desired angular displacement between electrical phases A, B and C. In FIG. 6, there are nine tracks 49 on each layer of PCI 47. Since the stator 41 embodiment in FIG. 8 is three-phase, each track 49 in phase A is displaced 120 electrical degrees in addition to the other tracks 49 in phase A, and 40 electrical degrees in addition to adjacent tracks 49 in phases B and C. Tracks 49 in phase B (relating to phases A and C) and phase C (relative to phases A and B) are equally spaced.
[0066] In some embodiments, each coil (for example, track 49) can consist of a single electrical phase. Alternatively, the coils can be configured to enable stator 41 with two or more electrical phases (for example, three phases shown in FIG. 8).
[0067] The example in FIG. 9 is a simplified view of only a few interior components of an embodiment of the device 31. Each of the magnets 37 may include a radial edge or element 67 (also referred to herein as "radial edge of the magnet 67"), and each of the tracks 49 may include an edge or element 69 (also referred to herein as "radial edge of coil 69"). The magnets 37 are part of the rotor 33 (FIG. 2) and rotate around the axis 35 in relation to the stationary stator 41. When the parts of the radial edges of the magnets 37 and the tracks 49 align rotationally around the axis during operation of the device 31, at least parts of the radial elements 67, 69 can be inclined (i.e., not parallel) with respect to each other. In some embodiments, when the parts of the radial edges of the magnets and coils align rotationally around the axis, the radial edges of the magnet and the radial edges of the coil are not parallel and are angled at an angle to each other. FIG. 9 illustrates a rotational position of the magnets 37, in which a part of the radial edge of the magnet 37 (i.e., the radial edge of the magnet 69 near the corner of the magnet 37) is rotationally aligned with a part of the radial edge of the coil 49, and which illustrates the slope between the radial edge of the magnet 69 and the radial edge of the coil 67. In one version, the radial elements 67, 69 can be radial leading edges or radial trailing edges of the magnets 37 and tracks 49. In another example , the radial edges or elements of the magnet and track 67, 69 can be straight as shown, and no part of the radial elements of the magnet and track 67, 69 are parallel when magnets 37 and tracks 49 are rotationally aligned in the axial direction .
[0068] In some embodiments, the radial elements of the magnet 67 can be tilted angularly with respect to the radial elements track 69, and the angular inclination can be greater than 0 degrees, such as greater than 0.1 degrees, at least approximately 1 degree, at least approximately 2 degrees, at least approximately 3 degrees, at least approximately 3 degrees, at least approximately 4 degrees, or even at least approximately 5 degrees. In other versions, the angular inclination cannot be more than approximately 90 degrees, for example, not more than approximately 60 degrees, not more than approximately 45 degrees, not more than approximately 30 degrees, not more than approximately 25 degrees, not more at approximately 15 degrees, not more than approximately 10 degrees, or even not more than approximately 5 degrees. Alternatively, the angular slope can be in a range between any of these values.
[0069] In an alternative embodiment, at least parts of the radial elements 67, 69 can be parallel to each other during rotational alignment. II. SEGMENTS
[0070] Some embodiments of an axial field rotational energy device can be configured similarly to that described for device 31, including mounting hardware, except that the stator can be configured somewhat differently. For example, FIGS. 10-12 represent a simplified version of a device 131 with only a few elements shown for ease of understanding. Device 131 may include a stator 141 that is coaxial with a rotor 133. Optionally, each rotor 133 may include one or more slots or grooves 136 (FIG. 10) that extend through it. In some versions, the grooves 136 are inclined with respect to axis 135 (FIG. 12) and, therefore, are not merely vertical. The angles of the grooves 136 can be provided at constant slopes and can facilitate a flow of cooling air into the device 131. The grooves 136 can allow the air flow to be pulled or pushed through and / or around the rotors 133 and to cool effectively the stators 141. Additional grooves can be provided in the rotor spacers, such as the rotor spacer 143 (FIG. 12), particularly in embodiments with a plurality of stator segments, and particularly in embodiments with a diameter inner R-INT of the stator assembly (FIG. 14), regardless of the outer diameter R-EXT.
[0071] Instead of including a single panel PCI 45, as described for stator 41, stator 141 may include a plurality of segments of stator 142, each of which may be a separate PCI 145. The stator segments 142 can be coupled together, for example, mechanically and electrically. Each stator segment 142 can include a printed circuit board (PCI) with one or more layers of PCI 147 (FIG. 13), as described elsewhere in this document. In one example, each PCI 145 can have an even number of layers of PCI 147. In an alternative embodiment, PCI 145 can have an odd number of layers of PCI 147.
[0072] The embodiments of the stator segments 142 can comprise or correspond to only one electrical phase. Additionally, the stator 141 of the device 131 can be composed of or correspond to only one electrical phase. In other versions, stator 141 may contain or correspond to a plurality of electrical phases. As shown in FIG. 13, each stator segment 142 includes at least one layer of PCI 147 with at least one conductive track 149, as shown in the coil. In some versions (FIG. 14), each stator segment 142 may have at least one layer of PCI 147 with a plurality of tracks 149 (for example, coils) that are coplanar and angularly spaced around each other around axis 135 (FIGS 11 and 12). In one example, each track 149 may comprise a single electrical phase. In another version, each stator segment 142 can include a plurality of layers of PCI 147, each of which can be configured to correspond to only one electrical phase. In some versions, each layer of PCI 147 in each stator segment 142 may include a plurality of axially coplanar tracks 149 that are configured to correspond to only one electrical phase.
[0073] In some embodiments (FIG. 13), each layer of PCI 147 can include at least one radial track 150 ranging from an inner diameter (ID) of PCI 145 to an outer diameter (OD) of PCI 145. In one example, each layer of PCI 147 may include a track 149 that is continuous from a portion of the trail in the outermost region 152 to a portion of the trail in the innermost region concentrically 154. Tracks 149 may include radial trails 150 with straight sides and chamfered corners 156. The straight sides of the radial tracks can be tapered, having a width of tracks increasing with increasing radial distance. The turning tracks at the inner end 146 and the turning tracks at the outer end 148 extend between the radial tracks 150 to form a concentric coil.
[0074] With respect to tapered tracks and coils, tapering can improve the amount of conductive material (for example, copper) that can be included in a PCI stator. Since many motors and generators have a round shape, the coils can generally be circular and, to collectively fit in a stator, the perimeters of the coils can be a little pizza-shaped or triangular. In some versions, the coils can be the same width in a plane perpendicular to the axis, and in other versions the coils can be tapered to increase the conductive densities (for example, copper) of the coils. Improving the density of copper can be of significant value in reducing electrical resistance, I2R losses and heat generation, and increasing the ability to carry a greater electrical current to provide a machine with greater efficiency.
[0075] In another version, each layer of PCI 147 can include only straight tracks 149 (FIGS. 15-17). Rectilinear tracks 149 can be continuous from a track in the outermost region 152 to a track in the outermost region concentrically 154. In one example, no track 149 of the PCI 147 layers is non-straight. However, embodiments of the single rectilinear tracks 149 may include turns, such as, for example, rounded corners or beveled corners. As used here, a "turn" includes a portion of the track connecting a radial track to a turning track at the far end. In other embodiments, the PCI layer 147 may include one or more non-straight tracks, with curved tracks.
[0076] As noted here, PCI 145 can include a plurality of layers of PCI 147 that are spaced apart in the axial direction. The layers of PCI 147 may comprise pairs of layers 157 (FIG. 17; see pairs 157.1 to 157.4). Each pair of layers 157 can be defined as two layers of PCI that are electrically coupled. In one version, at least one of the PCI 147 layers of the PCI is electrically coupled to another layer 147 of the PCI in series or in parallel. In another version, at least one pair of layers 157 is electrically coupled to another pair of layers 157 in series or in parallel. In one embodiment, at least one of the pairs of layers 157 comprises two layers of PCI 147.6 and 147.7 that are axially adjacent to each other. In another embodiment, at least one of the pairs of layers 157 comprises two layers of PCI 147.1 and 147.3 that are not axially adjacent to each other. Likewise, at least one of the pairs of layers 157 can be axially adjacent to the pair of layers 157 to which said at least one of the pairs of layers is electrically coupled. Conversely, at least one of the pairs of layers 157 may not be axially adjacent to the pair of layers 157, to which said at least one of the pairs of layers 157 is electrically coupled.
[0077] The embodiments of the layers of PCI 147 of PCI can include at least one set of layers 181 (FIG. 17). For example, the set of layers 181 can include a first layer 147.1, a second layer 147.2, a third layer 147.3 and a fourth layer 147.4. In some versions, a first path 159 can couple the first layer 147.1 to the third layer 147.3, a second path 155 can couple the third layer 147.3 to the second layer 147.2, and a third path 159 can couple the second layer 147.2 to the fourth layer 147.4. In one example, the first, second and third pathways 159, 155, 159 are the only pathways that internally couple the layers in the 181 layer set. In these examples, the two layers of PCI directly adjacent axially 147.1 and 147.2 are not electrically coupled to one another. the other. In FIG. 17, each of the pathways 159 couples a pair of non-adjacent PCI layers 147 while bypassing (i.e., not making contact with) the intermediate PCI layer 147. For example, via 159.1 couples the PCI layer 147.1 to the PCI layer 147.3, and does not make contact with the PCI layer 147.2. Conversely, each of the 155 pathways couples a pair of adjacent PCI 147 layers. For example, through 155.2, the PCI 147.2 layer is coupled to the PCI 147.3 layer. Each path 155, 159 that couples the respective pair of PCI layers, forms a corresponding pair of layers 157. For example, layer pair 157.1 includes the PCI layer 147.1 and the PCI layer 147.3. The 157.2 layer pair includes the PCI 147.2 layer and the PCI 147.3 layer. The 157.3 layer pair includes the PCI 147.2 layer and the PCI 147.4 layer. The 157.4 layer pair includes the PCI 147.4 layer and the PCI 147.5 layer. The 157.5 layer pair includes the PCI 147.5 layer and the PCI 147.7 layer. The 157.6 layer pair includes the PCI 147.6 layer and the PCI 147.7 layer. The 157.7 layer pair includes the PCI 147.6 layer and the PCI 147.8 layer.
[0078] In FIG. 17, each route is shown with a blunt end and a pointed end. This shape is not intended to imply any structural difference between the two ends of each path, but rather to provide a consistent indication of the direction of current flow through each path. In addition, while each lane is also shown to extend vertically only as far as necessary to couple the corresponding pair of PCI 147 layers, in certain embodiments each lane can be implemented as a coated through-hole lane if it crosses the PCIs completely. (for example, see several 59 in FIG. 6D). Each of these coated through-hole paths can make contact with any layer of PCI 147 that has a track 149 that overlaps that path. In the embodiment shown in FIG. 17, a given through-hole path overlaps and makes a connection with only two layers of PCI 147, while tracks 149 of all other layers of PCI 147 do not overlap the given path and are not connected to the given path. Alternatively, some embodiments may include buried paths that extend vertically only between layers 147 of the corresponding PCI to be connected. III. MODULES
[0079] FIGS. 18, 19, 20A-20H disclose embodiments of a module 201 for one or more axial field rotational energy devices 231. The device (s) 231 may include any of the device embodiments of axial field rotational energy disclosed here. In the embodiments shown in these figures, module 201 includes a housing 203 with a side wall 211, three stators (shown as PCI stator panel 245) and four rotor sets 242, 244. Each rotor set 244 is positioned vertically between two stators 245, and includes a pair of identical rotor panels 236 and a group of permanent rotor magnets 237. Each panel of rotor 236 includes a set of recessed notches to position each of the rotor magnets 237, and the two panels of rotor 236 are sandwiched together to each of the groups of rotor magnets between the opposing upper and lower rotor panels 236. Each rotor assembly 242 is positioned vertically between a stator 245 and a housing 203, and includes a plate torque 233, a rotor panel 234 and a group of rotor permanent magnets 237.
[0080] The vertical spacing between rotor assemblies (for example, 242, 244) is maintained by spacers (for example, 262, 263) that extend from a rotor assembly to the adjacent rotor assembly through a hole in the panel of the intermediate stator 245. The spacing between rotors corresponds to the thickness of the stator panel 245 and the desired air gap spacing (as above and / or below) of the stator panel 245. Each rotor spacer can define the air gap between the set of rotor and stator (and you can also set the height 215 of the side wall grooves, as shown below). Each rotor spacer is positioned between two rotor assemblies. For example, rotor spacer 262 is positioned between upper rotor assembly 242 and adjacent inner rotor assembly 244 (and also for lower rotor assembly 242). Each rotor spacer 263 is positioned between adjacent inner rotor assemblies 244. As shown here, such rotor spacer 263 may have a different thickness than that of rotor spacer 262, due to mechanical differences in the highest and lowest rotor assemblies 242 with respect to internal rotor assemblies 244, to define the same air gap spacing between all rotors and stators. The use of rotor spacers 262, 263 allows stacking of several rotors (for example, rotor assemblies 242, 244), which can provide significant flexibility in the configuration of module 201.
[0081] Embodiments of housing 203 may include a side wall 211 (FIGS. 20A-20H and 21). Sidewall 211 can be configured to orient the stator (e.g., stator panel 245) in the desired angular orientation around axis 235. For applications that include a plurality of stators 245, sidewall 211 can include a plurality of sidewall segments 212. Sidewall segments 212 can be configured to angularly compensate for the plurality of stators 245 at the desired electrical phase angles (see, for example, FIGS. 20C and 25) for module 201, around the axle. In one example, side wall 211 may include a radial inner surface with one or more grooves 214 formed therein. Each groove 214 can be configured to receive and maintain the outer end of stator 245 to maintain the desired angular orientation of stator 245 around axis 235. In the embodiment shown in FIGS. 20A-20H, each sidewall 211 includes three grooves 214 formed between corresponding pairs of sidewall segments 212. In some embodiments, the upper and lower sidewall segments are identical and therefore can be used interchangeably, but in other contemplated embodiments, the upper and lower segments of the side wall 212 may be different due to the asymmetric grooves 214, differences in the placement of the mounting hole or some other aspect.
[0082] In addition to providing the angular deviation of stators 245 as described above, grooves 214 can be configured to axially position, for example vertically, the outer edge of each stator 245 in prescribed axial positions in relation to other stators 41. Once that the rotor spacers 262, 263 determine the axial spacing between each stator 245 (in its innermost extension) and the corresponding rotor assembly (for example, 242, 244 in FIGS. 20A, 20B and 20D) on both axial sides (for example, 242, 244 in FIGS. 20A, 20B and 20D), above and below) of each stator 245, the combination of the side wall grooves 214 (i.e. the height 215 of those grooves 214) and the rotor spacers 262, 263 serve to maintain a precise air gap between stator 245 and rotor assemblies 242, 244. In other embodiments with a single stator 245, each side wall segment 212 can be configured to provide a wall slot lateral 214. The g set of side wall segments 212 together provide numerous grooves 214 (e.g. eight slots 214) radially spaced around module 201. It can be considered that collectively, these side wall slots 214 make air gap spacing between the stator and the adjacent rotor possible.
[0083] Versions of module 201 may include a housing 203 with mechanical characteristics (for example, keyed shafts 209 in FIG. 21) configured to mechanically couple housing 203 to a second housing 203 of a second module 201. Additionally, the housing 203 can be configured with electrical elements (for example, electrical connector couplings 204 in FIGS. 21 and 22) to electrically couple housing 203 to second housing 203. In one example, module 201 is air-cooled and not cooled liquid. In other versions, liquid-cooled embodiments can be used.
[0084] In some examples, module 201 can be configured to be indirectly coupled to the second module 201 with an interposing structure, such as a frame 205 (FIGS. 21-22). Module 201 can be configured to be coupled directly to frame 205, so that module 201 is configured to be indirectly coupled to the second module 201 with other components, depending on the application. In another example, module 201 can be configured to be directly coupled to the second module 201 without frame, chassis or other intervening structure.
[0085] In some embodiments, at least one rotor 233, at least one magnet 237 and at least one stator 241 with at least one PCI 245 and at least one PCI 147 layer with at least one track 149, can be placed on the inside and surrounded by housing 203.
[0086] In some versions, each 201 module consists of a single electrical phase. In other versions, each module 201 comprises a plurality of electrical phases. Examples of each module 201 may include a plurality of PCI 245 panels (FIGS. 20A-20H). Each PCI 245 panel can include a single electrical phase or a plurality of electrical phases. PCI panels can be single panels or can include stator segments, as described elsewhere in this document.
[0087] In one version, module 201 and second module 201 can be configured to be identical to each other. In another version, module 201 and second module 201 may be different. For example, module 201 may differ from the second module 201 in at least one of the following variables: power input or output, number of rotors 233, number of magnets 237, number of stators 41 (see previous drawings), number of PCI 245 , number of PCI layers 47 (see previous drawings), number of tracks 49 (see previous drawings) and angular orientation around axis 235. For example, in some embodiments, one or more of these variables can be modified to achieve differences in energy efficiency, torque, achievable revolutions per minute (RPM), so that different 201 modules can be used to better adapt the operation depending on the load or other desired operational parameter.
[0088] Some embodiments of module 201 may include at least one lock 207 (FIGS. 23 and 24) configured to mechanically fix the modules together. FIG. 23 represents the modules nested together with the latches 207 open, and FIG. 24 represents the modules nested together with the latches 207 closed. In one example, the latches 207 can be arranged symmetrically around the axis 235. In another version, an upper module (not shown) can be configured to be axially on top of another module, and the upper module may differ structurally from the second module. For example, the top module 201 can include latches 207 only on its bottom side and omit such latches 207 on its top side. As another example, axis 209 may extend from lower module 201, but not from upper module 201.
[0089] As shown in FIGS. 21-24, module 201 may include a keyed shaft 209. Module 201 can be mounted on the keyed shaft which can be configured to mechanically couple to another module 201.
[0090] Some embodiments may further include a body 213 (FIG. 26) (also referred to herein as a "housing"). The body 213 can be configured to contain and coaxially assemble a plurality of modules 201 within the body 213. In the illustrated example, the body 213 comprises two halves that are coupled with screws. For versions where each module 201 comprises a single electrical phase, and body 213 can be configured to maintain modules 201 at a desired electrical phase angle around axis 235. For versions where body 213 comprises a plurality of phases electrical, and body 213 can be configured to hold modules 201 at the desired electrical phase angles around axis 235.
[0091] In other versions, there may be a plurality of bodies 213. Each body 213 may include mechanical characteristics, such as coupling structures configured to mechanically couple each body 213 to at least one other body 213, and electrical elements configured to couple electrically each body 213 to at least one other body 213. Each body 213 can be configured to engage directly or indirectly with at least one other body 213.
[0092] In some embodiments of generators, a body (or more than one body, coupled to each other) can include several electrical phases (for example, approximately between 4 and 99; for example, at least 10, 11, 12 , 13, 14, 15 or more) of alternating current output. Thus, the AC current output can act as a direct current (DC) output with residual ripple without being rectified or require a power conversion. In other versions, this AC current output can be rectified.
[0093] Ways of carrying out a system for supplying energy are also disclosed. For example, the system may include a plurality of modules 201 which include axial field rotational energy devices. The 201 modules can be interchangeably connected to each other to configure the system for a desired power output. Each module can be configured based on any of the embodiments described here. The system can include a generator or an engine. The embodiments of the system may include at least two of the modules 201 configured to differ. For example, modules 201 can differ from each other in at least one of the following variables: output or input power, number of rotors, number of magnets, number of stators, number of PCIs, number of layers of PCI, number of coils and angular orientation in relation to the axis.
[0094] Ways of carrying out a method of repairing an axial field rotational energy device are also disclosed. For example, the method may include the following steps: providing a body 213 with a plurality of modules 201. Each module 201 can be configured as described for any of the embodiments disclosed herein. The method can also include mechanical and electrical coupling of modules 201 so that modules 201 are coaxial; operate the axial field energy device; detecting a problem with one of the 201 modules and stopping the operation of the axial field power device; open body 213 and disconnect problem module 201 from all other modules 201 to which problem module 201 is connected; install a replacement module 201 in the body 213 in place of the problem module 201 and connect the replacement module 201 to the other modules 201 to which the problem module 201 has been connected; and then, resume operation of the axial field power device.
[0095] Other embodiments of the method include the angular alignment of the modules with at least one desired electrical phase angle around the axis. In another version, the method may include providing a plurality of bodies 213, and mechanically and electrically coupling bodies 213.
[0096] Still other embodiments of a method of operating an axial field rotational energy device may include providing a housing with a plurality of modules, each module comprising a housing, rotors mounted in the housing so as to allow rotation, each rotor comprises a shaft and a magnet, stators mounted in the housing coaxially with the rotors, each stator comprises a printed circuit board (PCI) with a coil, each stator consists of a single electrical phase, and certain stators are defined in desired phase angles around the axis; mechanically and electrically couple the modules so that the modules are coaxial within the housing and then operate the axial field power device. In other words, adjusting the single-phase stators at the same phase angle can form a single-phase machine, and adjusting the single-phase stators at variable phase angles can form a multiphase machine (or more than 2 phases).
[0097] Optionally, the housing and each module can contain a single electrical phase, and the method can include the angular alignment of the modules at a desired electrical phase angle around the axis. The method can include the housing with a plurality of electrical phases, each module comprising a single electrical phase and angularly orienting the modules at the desired electrical phase angles around the axis. The housing and each module can include a plurality of electrical phases and angularly misalign the modules at the desired electrical phase angles with respect to the axis.
[0098] Some versions of the method may include the provision of a plurality of bodies, and the method also includes the mechanical and electrical coupling of the bodies to form an integrated system. Each module can include a plurality of stators that are angularly offset from each other around the axis at the desired electrical phase angles. In one example, each stator consists of just one printed circuit board. In other examples, each stator comprises two or more printed circuit boards that are coupled together to form each stator. In yet another version, the cabinet may have a number of alternating current (AC) electrical output phases that is substantially equivalent to a clean direct current (DC) with residual ripple without a power conversion, as described in this document.
[0099] In other versions, a method of repairing an axial field rotational energy device may include providing a plurality of bodies coupled together, each housing with a plurality of modules, each module with a housing, an assembled rotor in the housing so as to allow rotation, the rotor with a shaft and a magnet, a stator mounted in the housing coaxially with the rotor and the stator with a printed circuit board (PCI); mechanical and electrical coupling of the modules; operation of the axial field rotational energy device; detecting a problem with a first module in a first frame and stopping the operation of the axial field rotational energy device; opening the first housing and disassembling the first module from the first housing and any other module to which the first module is connected; installation of a second module in the first housing instead of the first module and connection of the second module to said any other modules to which the first module was connected; and then restarting the operation of the axial field rotational energy device.
[0100] The embodiments of each module can have only one orientation inside the case, so that each module can be installed or uninstalled in relation to the case in a unique way. The purpose of such projects is that the person working on the system cannot reinstall new modules on an existing system in the wrong position. This can only be done in a single orientation. The method can occur while the operation of the AFRED is suspended, and the treatment of the first module occurs without interrupting any other module, and without modifying or impacting any other module.
[0101] FIG. 27 represents another embodiment of a PCI 311 stator for an axial field rotational energy device, such as those disclosed in this document. The PCI stator 311 comprises a substrate with one or more tracks 313 that are conductive of electricity. In the version shown, the PCI stator 311 comprises eight track coils 313. Additionally, the PCI stator 311 can contain more than one layer of tracks 313. The tracks 313 on each layer are coplanar with the layer. Additionally, tracks 313 are arranged around a central axis 315 of the PCI stator.
[0102] FIG. 28 is an enlarged top view of a part of the PCI stator of FIG. 27. In the embodiment shown, each track 313 comprises radial portions 317 (in relation to axis 315) and turns at ends 319 extending between radial portions 317. Each track 313 can be divided with a slot 321. In in some versions, only the radial portions 317 have slits 321. Slits 321 can help to reduce the losses due to eddy current during operation. Eddy currents are opposed to the magnetic field during operation. The reduction of eddy currents increases the magnetic force and increases the efficiency of the system. In contrast, wide trails can allow eddy currents to form. Cracks in tracks 313 can reduce the possibility of eddy currents. Slits can force the current to flow more efficiently through the 313 tracks.
[0103] The axial field rotational energy device may include an "intelligent machine" that includes one or more sensors integrated with it. In some embodiments, this sensor can be configured to monitor, detect or generate data on the operation of the axial field rotational energy device. In certain embodiments, the operational data may include at least some data between power, temperature, speed of rotation, position of the rotor or vibration.
[0104] Versions of the axial field rotational energy device may include an integrated machine that includes one or more control circuits integrated with the device. Other versions of the axial field rotational energy device may include a fully integrated machine that includes one or more sensors and one or more control circuits integrated with the device. For example, one or more sensors and / or control circuits can be integrated into the printed circuit board and / or integrated into the housing. For engine designs, these control circuits can be used to drive or drive the machine. For example, in some motor embodiments, this control circuit may include a coupled input to receive an external power supply and may also include a coupled output to supply a current that flows through one or more stator coils. In some embodiments, the control circuit is configured to provide torque and / or torque commands to the machine. In some generator embodiments, such a control circuit may include a coupled input to receive current flowing through the coil, and may also include a coupled output to externally generate a power supply.
[0105] For example, one or more sensors and / or control circuits can be integrated with the stator 311 of the printed circuit board. FIG. 29 shows another exemplary stator 340 with integrated sensors (for example, 342, 346) that are attached to its upper layer of PCI 47. One of these sensors 342 is coupled to a secondary coil 344 that can be used to transmit / receive data from / for an external device, and can also be used to attach power to the 342 sensor. In some embodiments, the secondary coil can be configured to use magnetic flux developed during operation to supply power to the 342 sensor. In some embodiments , the secondary coil can be configured to receive inductively coupled energy from an external coil (not shown). Secondary coil 344 can also be referred to herein as a micro coil, or a miniature coil, since, in certain embodiments, that secondary coil may be much smaller than a stator coil 49, but it is not intended to infer the size relative. On the contrary, this secondary coil 344 is distinct from the stator coils 49 that cooperate with the rotor magnets, as described above. This secondary coil integrated in the 311 PCI stator can, in certain embodiments, be positioned in the 311 PCI stator (for example, manufactured or attached to its upper layer of PCI 47). This secondary coil integrated in the PCI stator 311 can, in certain embodiments, be positioned inside (i.e. integrated in the interior) of the PCI stator 311. In some embodiments, secondary coil 344 supplies power to a sensor connected to it. This coupled supply can be the primary or auxiliary energy for the sensor.
[0106] The sensor 346 is coupled to the first terminal 51 for one of the tracks 49 in the upper layer of the printed circuit board 47 and can detect an operational parameter, such as voltage, temperature in that location and can also be powered by the mounted coil (for example , one of the coils 49). Sensor 348 is attached to an external terminal 350, and can also detect an operational parameter such as voltage, temperature at that location, and can also be powered by the voltage attached to external terminal 350. Sensor 350 is positioned on an outer edge of stator 340 of the printed circuit board, but is not coupled to any conductor at layer 47 of the PCI.
[0107] In some embodiments, such a sensor can be incorporated directly into one of the coils 49 and can be electrically powered directly from the coil 49. In some embodiments, such a sensor can be powered and connected to the coil 49 via a connection separate that is positioned on or embedded in layer 47 of the PCI, such as the connection between the first terminal 51 and the sensor 346. Such a connection can be positioned in layer 47 of the PCI or positioned inside the PCI (for example, in an inner layer PCI). In other embodiments, the sensor and / or circuit can draw power from an external power source. For example, one type of external power supply may be a conventional wall outlet that can be attached to the engine or generator housing.
[0108] The sensors can provide operators of generator or engine products with operational data in real time, as well as, in certain embodiments, predictive data on various product parameters. This can include how the equipment is operating and how and when to schedule maintenance. This information can reduce product downtime and increase product life. In some embodiments, the sensor may be integrated within the housing. In some examples, the sensors can be embedded in the PCI stator 340, as shown in FIG. 30 (for example, sensors 362, 366, 368, 372 and coil 364).
[0109] An example of a sensor for these applications is a Hall effect sensor. Hall effect sensors are used for proximity switching, positioning, speed detection and current detection applications. In its simplest form, the Hall effect sensor operates like an analog transducer, directly returning a voltage.
[0110] Another example of a sensor is an optical sensor. Optical sensors can measure the intensity of electromagnetic waves in a wavelength range between UV light and near infrared light. The basic measuring device is a photodiode. Combining a photodiode with electronics gives way to a pixel. In one example, the optical sensor may include an optical encoder that uses optics to measure or detect the positions of the magnetic rotor.
[0111] Another example of a sensor is a thermocouple sensor for measuring temperature. Thermocouples comprise two wire strands made of different metals. The wires are welded at one end, creating a joint. The junction is where the temperature is measured. When the junction undergoes a change in temperature, a voltage is created.
[0112] Another optional sensor is an accelerometer. Accelerometers are an electromechanical device used to measure acceleration forces. Such forces can be static, such as the continuous force of gravity or, as is the case with many mobile devices, dynamic to detect movement or vibration. Acceleration is the measurement of the change in vector velocity, or scalar velocity divided by time.
[0113] A gyro sensor (“gyro”), which works like a gyroscope, can also be used in these systems. Gyro sensors can be used to provide stability or maintain a reference direction in navigation systems, autopilots and stabilizers.
[0114] The PCI 340 stator can also include a torque sensor. A torque sensor, torque transducer or torque meter is a device for measuring and recording torque in a rotational system, such as an axial field rotational energy device.
[0115] Another optional sensor is a vibration sensor. Vibration sensors can measure, display and analyze straight line speed, displacement and proximity, or acceleration. Vibration, even the slightest vibration, can be a telltale sign of a machine's condition.
[0116] In several embodiments, the sensors shown in FIG. 29 and FIG. 30 can also represent control circuits integrated with the stator 345 of the printed circuit board. Such control circuits can be positioned on a surface of the printed circuit board (analogously to the sensors described in FIG. 29), positioned inside (ie embedded in) the printed circuit board (analogously to the sensors described in FIG. 30) , and / or integrated with or inside the housing (for example, housing 203 in FIG. 18).
[0117] In some embodiments of generators, the control circuit can implement the power conversion of an AC voltage developed in the stator coils into a desired external power source (for example, an AC voltage with a different magnitude than the voltage of the coils, a DC voltage developed by rectifying the voltage of the coils). In some embodiments of the motor, the control circuit may implement an integrated drive circuit that can supply desired AC current waveforms to the stator coils to drive the motor. In some examples, the integrated controller may be a variable frequency drive (VFD) and may be integrated in the same housing as the motor. The sensors and / or circuits disclosed here can be connected wirelessly or wired to any element of the housing, outside or inside it. Alternatively, the sensors and / or circuits can be located remotely in relation to the housing.
[0118] Each of these sensors and control circuits can include a wireless communication circuit configured to communicate with an external device through a wireless network environment. Such wireless communication can be unidirectional or bidirectional, and can be useful for monitoring a state of the system, operating the system, communicating predictive data, etc. Wireless communication via the network can be performed using, for example, at least one of Long Term Evolution (LTE), LTE-Advanced (LTE-A), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Universal Mobile Telecommunication System (UMTS), Wireless Broadband (Wibro), or Global System For Mobile Communications (GSM), as a cellular communication protocol.
[0119] In addition or alternatively, wireless communication may include, for example, short-range communication. Short-range communication can be carried out, for example, by at least one of Wireless Fidelity (Wifi), Bluetooth®, Near Field Communication (NFC), or GNSS. GNSS may include, for example, at least one of the Global Positioning System (GPS), the Glonass® global satellite navigation system, the Beidou® satellite navigation system or Galileo®, the European global satellite navigation system . In the present disclosure, the terms "GPS" and "GNSS" are used interchangeably. The network can be a communication network, for example, at least a computer network (for example, local area network (LAN) or wide area network (WAN)), the Internet, or a telephone network.
[0120] In certain embodiments, such a wireless communication circuit can be coupled to a secondary coil (for example, secondary coil 344) to communicate telemetry information, such as the operational data described above.
[0121] FIGS. 31 and 32 show the embodiment of a set for mechanically coupling the stator segments 380 to form a stator. A lock 382 slides over parts of a mounting plate 381 on two adjacent stator segments 380, which is secured by a pair of nuts on each of the two screws (eg, screw 384). The lock 382 includes an alignment tongue 392 which can be positioned in a side wall groove 214 as described above. The end in the inner diameter of the two adjacent stator segments 380 slides in a channeled rotor spacer 390 in the form of an annular ring. In some embodiments, this rotor spacer 390 can rotate on an axial bearing with the rotor to allow the rotor spacer 390 and stator to remain stationary while the rotor rotates. In other embodiments, a rotor spacer as described above (for example, FIGS. 18, 20A-20H) can fit within the open center of the channelized rotor spacer 390.
[0122] The electrical connection between the adjacent stator segments 380, 381 can be implemented using a wire 387 between the respective circuits 386, 388. Circuit 386 can connect to a track in the upper layer (or another layer using a path ) of stator segment 380. Similarly, circuit 388 can connect to a track on any layer of stator segment 381. Such circuits 386, 388 can include any of the sensors described above (FIGS. 29-30), but also they can simply provide an electrical connection from the respective printed circuit board to the 387 wire. In other embodiments, the electrical connection can also be made through the mounting surface of the printed circuit board as conductive material and connected to the coil and, in then, attach these components through the closure, which may also include conductive material on the inner surface of the same.
[0123] The electrical connection can also be made via lock 382 in combination with an electrically conductive mounting plate 383. If the mounting plate 383 is continuous and uninterrupted, clamps 382 can provide a common electrical connection around the circumference of the stator. If these mounting plates are discontinuous and divided into two parts (as illustrated by the track lines, with each part coupled to a respective track end on that segment, clamps 382 can connect these stator segments in series.
[0124] The axial field rotational energy device is suitable for many applications. The PCI 340 stator can be configured to a desired power criterion and form factor for devices such as permanent magnet generators and motors. Such designs are lighter in weight, easier to produce, easier to maintain and more capable of greater efficiency.
[0125] Examples of permanent magnet generator (PMG) applications may include a wind generator, micro generator application, permanent magnet direct drive generator, steam turbine generator, hydraulic generator, thermal generator, gas generator, generator firewood, coal-fired generator, high-frequency generator (eg frequency higher than 60 Hz), portable generator, auxiliary power unit, automobiles, alternator, regenerative braking device, PCI stator for auxiliary power generation device by regenerative braking, manual or automated backup power generation, PMG for manual or automated backup power generation, PMG for military use and a PMG for aerospace use.
