    The invention relates to a coil winding according to the preamble of claim 1.
    Coil windings are important components of standard electrical components, such as coil arrangements. Coil windings may act, for example, as an inductance in an electrical circuit, as a sensor, in a transformer, or as an actuator in an electric motor, to name just a few examples. A coil winding consists of a wound and insulated electrical conductor, such as a wire or a stranded wire. Especially when using a coil winding in an electric motor, the quality and the winding technology of the coil winding has a great influence on the properties of the electric motor. In an electric motor, for example, a high fill factor in the winding grooves of the magnetic core is important in order to minimize the length of the magnetic loop through the magnetic core, and thus to achieve a high power density of the electric motor.
    A particularly high fill factor can be achieved by a layer winding in which the coil winding has layer winding regions with a particularly high fill factor, since in the layer winding region the turns of the top winding can be arranged in the valleys of the lower winding.
    A disadvantage of such coil windings that form at high operating frequencies, such as occur in electric motors with high rotational speed, eddy currents, which make up the fact high filling factor again, whereby the power density of the coil winding and thus the electric motor is limited at high operating frequencies. This effect is also known under the name Skineffekt. At a higher number of revolutions, however, an electric motor can output a higher power at the same size, which is why higher operating frequencies are advantageous.
    The object of the invention is therefore to provide a coil winding of the type mentioned, with which the mentioned disadvantages can be avoided, and which have a high efficiency even at high operating frequency. 2/43 ···················································································································· ::::::::::::::::::::: not a word
    This is achieved by the features of claim 1 according to the invention.
    This results in the advantage that electrical components with coil windings can be operated with high efficiency even at high operating frequency. By using a plurality of winding wires in a layer winding, a high filling factor can be achieved, whereby smaller eddy currents occur due to the use of several winding wires with the same total cross section. As a result, smaller electric motors can be produced, for example, with the same power. Characterized in that the turns of the various winding wires in each winding layer are arranged side by side, the winding wires are homogeneously distributed uniformly throughout the coil winding, so that production-related differences in the properties of the individual winding wires, for example in electrical resistance, lead to no inhomogeneities of the magnetic field generated. As a result, such a coil winding can be produced with better properties but with a relatively similar production outlay as a conventional coil winding with a single winding wire with layer winding regions.
    The invention further relates to a coil arrangement according to the preamble of claim 9. A coil arrangement here denotes the combination of a coil winding and a coil support on which the coil winding is wound.
    Furthermore, the invention relates to a method for machine winding a coil winding according to claim 17.
    The object of this method is to produce a coil winding in a simple manner, which can be operated with high power even at high operating frequency.
    As a result, a coil winding can be provided in a simple manner, which has the above-mentioned advantages.

    FIGS. 1 to 13 show preferred embodiments of a coil arrangement 12 and of a coil winding 1. The coil winding comprises at least one layer winding region 2 with winding layers 3, the coil winding 1 having at least two winding wires 5 arranged in turns 4. The coil winding 1 is a component in the field of electrical engineering and comprises winding wires 5, which are wound in turns 4. When winding the coil winding 1 in this case for each winding wire 5 at a rotation of the coil winding 1 by 360 °, a turn 4 of this winding wire 5 is generated. By juxtaposing a plurality of turns 4 over the entire height of the coil, a, in particular gap-free, winding layer 3 can be generated. The coil winding may, in particular, have a multiplicity of winding layers 3, ie be multi-layered.
    The winding wire 5 is in this case an elongate electrical conductor, in particular made of metal, preferably copper, aluminum and / or silver, which may be formed as a one-piece wire or stranded wire with single strands, wherein the winding wire 5 via an insulation, for example an insulating lacquer layer. 5 / 43 ·· ··· ♦ ♦♦♦♦ ···· 5
    33fc46 / mo can have.
    The wound winding wire 5 in this case forms a conductor winding, which generates a magnetic field when electric current flows through, the strength of the magnetic field corresponding to the sum of the magnetic fields of the individual windings 4. The cross section of the winding wires 5 may in particular be circular, wherein the winding wires 5 are then formed as round wires. However, the winding wires 5 can also according to embodiments not shown have an elliptical, hexagonal or square or otherwise shaped cross-section.
    In particular, it may be provided that all winding wires 5 have the same cross section and winding wire diameter. The winding wire diameter is at a designed as a round wire winding wire 5, the diameter of the winding wire 5. In a differently shaped winding wire 5, the winding wire diameter as the average distance of the centers of adjacent turns 4 are considered.
    In at least one layer winding region 2, the winding wires 5 are arranged as a layer winding, wherein the individual turns 4 do not intersect in the layer winding region 2. In a layer winding, ie in the layer winding region 2, the turns 4 are arranged in superimposed winding layers 3, wherein in particular the turns 4 of an overlying winding layer 3 can be arranged in the valleys between the turns 4 of the underlying winding layer 3, whereby the turns 4 - in cross section seen - form a honeycomb-like structure. In a layer winding area 2, a fill factor of over 85% can be achieved with round wires.
    In particular, all the winding wires 5 in the layer winding region 2 can be essentially parallel, the arrangement of the turns 4 in a layer winding region 2 remaining substantially the same in the entire layer winding region, viewed in a cross section.
    The opposite of the layer winding is the wild winding, in which no 6/43 •················································································ · ♦ ··· · · · 6 · .. * · .. ·· .. ·· .. ·: 38646 / mo
    Winding layers 3 can be seen. In a wild winding, the fill factor is much lower.
    It is provided that in each winding layer 3 at least one layer winding region 2, each winding 4 of one of the winding wires 5 is arranged adjacent to a winding 4 of another of the winding wires 5 in a predeterminable or predetermined arrangement. This means, in other words, that the at least two winding wires 5 are wound into one another, and that not only a plurality of coil windings 1 with different winding wires 5 are wound on one another or next to one another.
    This results in the advantage that electrical components 20 can be operated with coil windings 1 even at high operating frequency and with high efficiency. By using a plurality of winding wires 5 in a layer winding, a high filling factor can be achieved, whereby smaller eddy currents occur by using a plurality of winding wires 5 with the same overall cross section. This plurality of winding wires 5 have compared to a single wire, which has the same cross section as the sum of the cross sections of the plurality of winding wires, substantially the same electrical resistance at DC. In the case of alternating current, however, the resistance of a large single wire increases considerably more than due to the skin effect, as is the case with several winding wires with a small cross section. As a result, smaller electric motors can be produced, for example, with the same deliverable power. Characterized in that the turns 4 of the different winding wires 5 are arranged side by side in each winding layer 3, the winding wires 5 are homogeneously distributed uniformly throughout the coil winding 1, so that production-related differences in the properties of the individual winding wires 5, for example in electrical resistance, to no inhomogeneities lead the generated magnetic field. As a result, a coil winding 1 formed in this way with better properties but with a relatively similar production outlay as a conventional coil winding 1 with a single winding wire 5 with layer winding regions 2 can be produced. As a result, a coil winding with improved properties at high operating frequencies can be produced economically.

    A first preferred embodiment of an electrical component 20 is shown in FIGS. 14 and 15. The first preferred embodiment of the electrical component 20 has a magnetic core 21 with two winding grooves 22, wherein the coil winding 1 is guided through the winding grooves 22 as a layer winding.

    Fig. 16 shows a part of a second preferred embodiment of an electrical component 20, which is provided for electric motors. Here, the magnetic core 21 is formed as a stator having a plurality of stator teeth 32. Inside the stator, a movable rotor 33 is arranged. Around each stator tooth 32, a coil winding 1 is wound. The openings 22 may in particular be open to the rotor. In Fig. 16, the layer winding portions 2 belonging to the same coil winding 1 are hatched similarly.
    In the coil winding may be particularly preferably provided that the coil winding has 1 layer jump regions 6, that the winding wires 5 are divided into at least two winding wire groups 7, that in the layer transition regions 6 per winding layer 3, a winding wire group 7 is guided in the next higher winding layer 3, and that the winding wire group 7, which is guided in the next higher winding layer 3, at the beginning and at the end of the same layer transition region 6 in the respective winding layers 3 is the outermost winding wire group 7. In other words, the winding wire group 7 is the outermost winding wire group 7 of a winding layer 3 at the beginning of the layer transition region 6 and the next higher winding layer 3 is guided in this layer transition region 6, at the end of this layer transition region 6in the next higher winding layer the outermost winding wire group 7. This can be an orderly winding the coil winding 1 also take place with a plurality of winding wires 5, wherein even after a plurality of winding layers 3, a layer winding in the layer winding regions 2 can be provided without crossing. The layer transition region 6 can thereby also be made particularly compact, ie with a high fill factor.
    In particular, the windings 4 of one winding layer 3 can intersect with the turns of the next higher winding layer 3 in the layer transition regions 6 by advancing the windings 4 in a feed direction 8. Furthermore, it can be provided that the feed direction 8 of two adjacent winding layers 3 is opposite. The advance of the windings can also be referred to as winding jump or winding advance.
    The winding wire group 7 with the - in the feed direction of the underlying - 9 9 999 9 9 4 9 9949 9994 9999 9 9 9 9 9 4 33646 / mo

This arrangement of the layer transition region 6 has also proven to be particularly stable and resistant to unwanted displacements.
    A winding wire group 7 may consist of one or more winding wires 5, wherein the position of the winding wires 5 in a winding wire group 7 remains unchanged from each other. In other words, the winding wires 5 of a winding wire group 7 are guided in parallel in the coil winding 1 and do not overlap each other. By combining several winding wires 5 in winding wire groups 7 less layer jump areas 6 are necessary.
    Furthermore, it can be particularly preferred that all winding wire groups 7 have the same number of winding wires 5. Thereby, the number of turns 4 can be kept constant in a winding layer 3, whereby a well-ordered winding over several winding layers 3 is made possible.

According to the first preferred embodiment, the normal distance between the first boundary surface and the second boundary surface is, for example, eighteen and a half winding wire diameters.
    In this case, it can be provided, in particular, that the winding wire group 7 guided in a layer transition region 6 into the next higher winding layer 3 is guided under the winding wire group 7, which at the beginning of this layer transition region 6 is the outermost winding wire group 7 of the next higher winding layer 3.

    Furthermore, it can be provided that the coil winding 1 has a coil winding inner side 9, and that the coil winding inner side 9 at at least one transition between a layer transition region 6 and a layer winding region 2, and / or at least one transition between two layer jump regions 6, a particular edge-shaped, deflection region 10th having. The coil winding inside 9 is the inside of the coil winding 1, which is enclosed by the innermost winding layer 3, and which is formed substantially equal to the winding surface 16 of the bobbin 13. An advantage of such deflection regions 10 is that the winding wires 5 can be reliably fixed at the beginning and at the end of a layer transition region 6.
    The region of the coil winding 1 over the deflection regions 10 can be designed in particular as a transition region 34. The transition region can be formed both as a layer winding region 2 or as layer transition regions 6, wherein the transition can be fluent.

Due to the spaced winding wire inlets 23, the winding wires 5 can be arranged well arranged on the winding surface, without causing buckling or buckling of the winding wires.
    In this case, it can preferably be provided that the introduction of the winding wires 5 takes place only in the lowermost winding layers 3.
    Leaving the winding wires 5 from the coil winding 1 is particularly preferably in the outermost winding layer. 3
    Particularly preferably, it can be provided that the winding wires 5 are continuous from the winding wire introduction 23 until leaving the coil winding 1.
    In particular, it can be provided that the winding wire inlets 23 are arranged at a beginning and / or at one end of a layer jump region 6. It can thereby be achieved that the winding wire 5 introduced at the beginning of the layer transition region 6 undergoes the same feed as in the further layer transition regions 6, whereby this first winding 4, 29 is parallel to the further turns 4 of the innermost winding layer 3 and thus a particularly uniform coil winding 1 can be achieved.
    Furthermore, it can preferably be provided that all winding wire inlets 23 are arranged in the same coil end region 28. As a result, the handling of the coil winding 1 is substantially simplified.
    Alternatively, it may be provided that the winding wire inlets 23 in 15/43 • · Μ «· ·« ····················································································· ···· ··· 15 ** ...... 3 * 3646 / mo different coil end face regions 28 are arranged.
    According to the first preferred embodiment, it may be provided, in particular, that the winding wire inlets 23 are formed as slots in the first coil flange side 14. The winding wire inlets 23 may alternatively be formed as openings through which the winding wires 5 are guided.

The first winding wire 5, 26 has an advance of substantially one winding wire diameter in this layer transition region 6, so that the first winding wire 5, 26 applies to the second winding wire 5, 27 at the end of the layer transition region 6.
    Furthermore, it can be provided that at least one padding 18 is arranged on the first spool flange side 14. The padding 18 supports the advance of the first turn 4, whereby an orderly and regular winding of the coil winding 1 is possible. In particular, the maximum height of the padding 18 may correspond to the winding wire diameter or the integer multiple of the winding wire diameter, wherein the height is measured parallel to the coil axis. The width of the padding 18, which is measured normal to the coil axis, may correspond in particular to a winding wire diameter.
    Furthermore, it can preferably be provided that the height of the upholstery 18 in the at least one layer winding region 2 is constant. As a result, the outermost turn 4 of the innermost winding layer 3 can be secured against undesired displacement in the layer winding region 2.
    The cross section of the upholstery 18, which can be considered as a section transverse to the feed direction 8, may in particular be substantially rectangular. 16/43 ·························································································································································
    FIG. 3 shows the rear side of the coil arrangement 12 in FIG. 2. FIG. 3 shows the upholstery 18, which rises continuously in the layer transition regions 6 to a height of one winding wire diameter. In subsequent layer winding region 2, the height of the padding 18 remains constant at a winding wire diameter. The padding 18 of the first preferred embodiment terminates immediately before the winding wire insertion 23 of the first winding wire 5,26, whereby the outermost turn 4 of the second winding wire 5,27 can be well fixed between two turns 4 of the first winding wire 5,26.
    Furthermore, it can be particularly preferably provided that the coil arrangement 12 at the transition between the winding surface 16 and the second Spulenflanschseite 15 at least one spacer 19, and in particular that the spacer 19 has a height of at least half a winding wire diameter. The width of the spacer 19 may in particular substantially correspond to a winding wire diameter. The spacer 19 is preferably shaped such that it corresponds to a half turn 4. A winding 4, which rests laterally on the spacer 19 at the beginning of a layer jump region 6, is guided onto the spacer 19 in the next higher winding layer 3 while in the position jump region 6. As a result, a better specifiable arrangement of the windings 4 can be achieved. The spacer 19 only supports the layer jump from the lowermost winding layer 3. In the other winding layers 3, the layer jump can take place without the support of the spacer 19.
    The height of the spacer 19 may in particular depend on the number of winding wires 5 of the winding wire group 7. In particular, the height of the spacer 19 may correspond to the number of winding wires 5 of the winding wire group 7 multiplied by the winding wire diameter less than half a winding wire diameter. If a winding wire group 7 comprises only one winding wire 5, the height of the spacer 19 corresponds to half a winding wire diameter, and if, for example, a winding wire group 7 comprises two winding wires 5, the height of the spacer 19 corresponds to one and a half winding wire diameters. This allows the entire 17/43 • ♦ 17: 33646 / mo
    Winding wire group 7 are guided in a layer jump areas 6 by means of the spacer 19 in the next higher winding position.
    The cross section of the spacer 19 may be shaped differently, wherein the cross section of the spacer 19 is the section transverse to the feed direction 8. According to the first preferred embodiment in FIGS. 4 and 5, the cross section of the spacer 19 may be substantially triangular. According to the second preferred embodiment, the cross section of the spacer 19 may be substantially rectangular with rounded corners.
    According to the preferred embodiments, the spacer 19 can run around the entire circumference of the winding surface 16. Alternatively, it can also be provided that the spacer 19 is interrupted in the layer transition regions 6. As a result, the larger space requirement in the layer transition region 6, which is caused by the intersecting turns 4, be taken into account.
    Particularly preferably, it can further be provided that the second spool flange side 15 and / or the first spool flange side 14 has an indentation 17 in at least one layer transition region 6. The depth of the indentation 17, which can be in particular between 5% and 50% of the winding wire diameter, can be measured in the feed direction 8, whereby more space is available for the coil winding in the region of the indentation 17 between the first spool flange side 14 and the second spool flange side 15. As a result, buckling of the coil winding 1 can be largely avoided, whereby even after a plurality of winding layers 3, a layer winding can be provided.
    10 and 11 show sections through the beginning and the end of a layer jump region 6 of a second preferred embodiment, which is identical to the first preferred embodiment except for the number of turns 4 per winding layer 3 and the cross section of the spacer 19. This layer jump region 6 corresponds to the layer jump region 6 of the first embodiment, which can be seen in FIG. 18/43 18 33646 / mo
    In the innermost winding layer 3, as shown in FIG. 10 twelve turns 4, wherein six turns 4 from the first winding wire 5.26 and six windings 4 from the second winding wire 5.27. The turns of the first winding wire 5,26 and the second winding wire 5,27 alternate in the first winding layer 3,24.
    In FIG. 10, the first winding 4, 29 of the second winding wire 5, 27 rests against the first side of the coil flange 14, the next winding 4 is then the first winding 4, 29 of the first winding wire 5, 26. On the opposite side of the innermost winding layer 3, which adjoins the second Spulenflanschseite 15, adjacent the sixth turn 4.30 of the first winding wire 5.26 to the spacer 19, followed by the sixth turn 4.30 of the second winding wire 5.27 ,
    The outermost turn 4 of the next higher winding layer 3 is the seventh turn 4.31 of the second winding wire 5, 27, the second outermost is then the seventh turn 4.31 of the first winding wire 5.26. The turns 4 of the next higher winding layer 3 are located in the recesses between the turns 4 of the first winding layer 3,24, wherein the seventh winding 4,31 of the second winding wire 5,27 is disposed in the recess, which by the sixth turn 4.30 of first winding wire 5.26 and the spacer 19 is formed, whereby the seventh winding 4.31 of the second winding wire 5.27 is offset by half a winding wire diameter with respect to the sixth winding 4.30 of the first winding wire 5.26 to the outside.
    FIG. 11 shows the section through the end of the layer transition region 6 from FIG. 10. All windings 3, except for the sixth winding 4, 30 of the first winding wire 5, 26, have advanced substantially in the feed directions of the respective winding layers 3 by a wire diameter. The sixth winding 4, 30 of the first winding wire 5, 26 has been led under the seventh winding 4, 31 of the second winding wire 5, 27 and has subsequently been led into the next higher winding layer 3, where the sixth winding 4, 30 of the first winding wire 5, 26 is now arranged at the former position of the seventh turn 4.31 of the second winding wire 5.27. The height of the padding 18 in the layer transition region 6 continuously increased by a winding wire diameter, so that the first winding 4,29 of the second winding wire 5,27 is still fixed. ·· ·· · ··· .. · '· · · · 33646 / mo
    Since the distance between the first coil flange side 14 and second coil flange side 15 substantially corresponds to an integer multiple of the winding wire diameter plus half a winding wire diameter, the positional jump will be similar to the first Spulenflanschseite 14 as the second Spulenflanschseite 15th
    Since the layer jump occurs substantially equally in each winding layer 3, the innermost winding layer and the next higher winding layer can be generalized as the first winding layer 3, 24 or as the second winding layer 3, 25, the first winding layer 3, 24 being closer to the coil axis, as the second winding layer 3,25. A difference between a layer jump from the innermost winding layer 3 into the next higher winding layer 3 and a layer jump between higher winding layers 3 is that the spacer 19 only supports the layer jump from the innermost winding layer. However, as previously stated, the spacer 19 is only an additional support and the layer jump in the higher-lying winding layers 3 can be done without the spacer 19.
    It can be provided that each layer jump takes place at each winding layer 3 according to the layer transition of the first winding layer 3,24 in the second winding layer 3,25. As a result, a regular self-supporting coil winding 1 can be formed.
    From the above statements it is further apparent that the arrangement of the winding wires 5 in the layer jump regions 6 is independent of the number of winding wire groups 7, since per layer transition region 6 preferably only one winding wire group 7 changes into the winding layer 3 and the following winding wire groups 7 preferably only according to the Feed and therefore move up. Due to the appropriate number of layer jump regions 6, therefore, a coil winding 1 can take place with any number of winding wire groups 7.
    To produce an advantageously designed coil winding 1, a method for winding a coil winding 1 by machine is provided, wherein at least two winding wires 5 are simultaneously wound in directly adjacent turns 4 to form a first winding layer 3, 24. · ··· ... $ 3646 / mo
    Winding layer 3,24 which lies above the first winding layer 3,24 second winding layer 3,25 is wound, the turns 4 of the second winding layer 3,25 in the layer winding region 2 of the coil winding 1 parallel to the turns 4 of the first winding layer 3,24 out become. As a result, an advantageous coil winding 1 can be provided in a simple manner.
    In particular, it may be provided that a coil winding 1 is wound with a multiplicity of winding layers 3, wherein the first winding layer 3, 24 is representative of the underlying winding layer 3 and the second winding layer 3, 25 is representative of the next higher winding layer 3.
    In particular, it can be provided that the coil winding 1 is wound on a coil carrier 13 according to one of the preferred embodiments by machine.
    In this case, the winding wires 5 can simultaneously be wound onto a bobbin 13 by means of a linear winding method or a flyer winding method, in particular from a plurality of nozzles, in order to produce the advantageously formed coil winding 1.
    The winding process of the coil winding 1 can be done directly on a bobbin 13. Alternatively, the winding process of the coil winding 1 can take place on a winding carrier of a winding machine, which winding carrier can be removed again after completion of the winding process to produce a self-supporting coil winding without coil carrier 13.
    It can preferably be provided that the winding wires 5 are wound up as at least two winding wire groups 7 simultaneously, and that the position of the winding wires 5 in a winding wire group 7 remains unchanged relative to one another. As a result, the effort for machine winding of the coil winding 1 can be kept low, whereby such a coil winding can be produced economically.
    Particularly preferably, it can be provided that, in the case of a layer jump, in particular in a layer transition region 6 of the coil winding 1, the outermost winding wire group 7 of the first winding layer 3, 24 reaches the position of an outermost 21/43 21 33646 / mo
    Winding wire group 7 of the second winding layer 3,25 is performed. The position of an outermost winding wire group 7 is the outermost position that a winding 4 can assume in the respective winding layer 3, and corresponds to the seventh winding 4, 31 of the second winding wire 5, 27 in FIG. 10. As a result, a layer winding can be achieved, since in a layer transition region 6 the outermost winding wire group 7 of an underlying winding layer 3 is guided to the outermost adjacent position of the next higher winding layer 3. As a result, a layer winding can be achieved even after a plurality of winding layers 3, without causing a disorderly winding or a wild winding.
    Furthermore, it can be provided, in particular, that a different winding wire group 7 in the first winding layer 3, 24 is first made under the outermost winding wire group 7 of the second winding layer 3, 25, and then into the position of an outermost winding wire group in the case of a directly following another layer jump 7 of the second winding layer 3.25 is performed. If a winding wire group 7 has already been guided into the second winding layer 3, 25 in the preceding layer jump regions 6, this winding wire group 7 is arranged at the beginning of the next layer jump region 6 at the position of an outermost winding wire group 7, into which the other winding wire group 7 are guided during the subsequent position jump should. The outermost pair of winding wires 7 of the second winding layer 3,25 is preferably led away from the adjacent boundary plane, wherein the other winding wire group 7 is guided in particular in the first winding layer 3,24 under this winding wire group 7 of the second winding layer 3,25, and only in the following second winding layer 3.25 is transferred. As a result, the one winding wire group 7 in the feed direction of the current winding layer 3 is always in front of the other winding wire group 7, whereby a controlled and predeterminable winding with several winding wires is facilitated.
    Furthermore, it can be provided, in particular, that in the layer transition region 6 the winding wire groups 7, which remain in the same winding layer 3, are displaced in the feed direction 8 by essentially one winding wire diameter or substantially an integral multiple of a winding wire diameter. How far the winding wire groups 7 are displaced depends on this ··· «·· ····· ·« · · ···· ···· «· · · · ·· ···· t · · ····· 22: $ 3646 / mo from the number of winding wires 5 of the winding wire groups 7, the number of integral multiples of a winding wire diameter corresponding to the number of winding wires 5 corresponding to the number of winding wire groups 7. With only one winding wire 5 per winding wire group 7, the feed corresponds only substantially to a winding wire diameter. Essentially a winding wire diameter corresponds to a range between 100% and 110% of a winding wire diameter. On the one hand, such deviations may correspond to the manufacturing tolerances but may also be necessary in order to optimally utilize more complex winding surface geometries without buckling occurring. As a result, the necessary space is created for the following winding wire groups 7 without the coil winding 1 being deformed, which would make a layer winding more difficult.
    In particular, it may further be provided that only one winding wire 5 is provided per winding wire group 7. As a result, a coil winding 1 with several winding wires can be wound in a simple manner.
    In FIGS. 4 to 9, the positional jump during the winding process of the first preferred embodiment of the coil arrangement 12 is shown in a plurality of states.
    This positional jump in FIGS. 4 to 9 serves for a better understanding and should not be construed restrictively.
    In FIG. 4, the first winding wire 5, 26 on the second coil flange side 15 has been guided from the first winding layer 3, 24 to the position of an outermost winding wire group 7 of the second winding layer 3, 25, while the second winding wire 5, 27 is at the end of the position transition region 6 has been guided to the position of an outermost winding wire group 7 of the first winding layer 3,24. Fig. 5 shows again the state in Fig. 4 from a different perspective, which is easy to see that the first winding wire 5.26 compared to the second winding wire 5.27 further by half a winding wire diameter to the outside, ie in the direction of the adjacent boundary plane , was transferred.
    FIG. 6 shows a state in which the first preferred embodiment of the coil arrangement 12 has been further rotated by 180 °, and thus the winding wires 5 have been further wound by half a turn 4, FIG. 6 showing the rear side of the 23/43 ··· « · »· * ··· FIG. 4 shows a preferred embodiment of the coil arrangement 12 of FIG. Between Fig. 4 and Fig. 6, the first winding wire 5.26 was led away by a winding wire diameter of the second Spulenflanschseite 15, whereby space for the second winding wire 5,27 was created. The second winding wire 5.27 is guided under the first winding wire 5.26 and then also in the second winding layer 3.25, so that both winding wires are now performed in the second winding layer 3.25.
    By the indentations 17 the second winding wire 5,27 more space is provided, whereby a bulging of the coil winding 1 can be prevented.
    FIG. 7 shows the first preferred embodiment of the coil arrangement 12 from FIG. 6 after a further 180 ° rotation, ie a further half turn 4. In the layer jump regions 6 visible in FIG. 7, both winding wires 5 were offset in the feed direction 8 by a winding wire diameter. At the end of the layer jump region 6 visible in FIG. 7, the second winding wire 5, 27 is arranged between the current turn 3 and the leading turn 3 of the first winding wire 5, 26. Fig. 8 again shows the state in Fig. 7 from an oblique perspective. FIG. 9 shows the first preferred embodiment of the coil arrangement 12 from FIG. 7 after a further 180 ° rotation.
    Since the illustrated method for machine winding a coil winding 1 with ply winding and a plurality of winding wires 5 parallel to a conventional method for machine winding a coil winding 1 with only one winding wire, the coil winding described here 1 or the method described here for machine winding a coil winding 1 with Other advantageous winding techniques will be combined.
    For example, the width of the winding grooves 22 for electric motors, as viewed from the rotor axis, may increase outwardly as shown in FIG. 16. By the use of support windings, which are arranged in provided gaps of the underlying winding layers 3, such coil windings 1 with complex-shaped outer geometry, for example in conical coil windings 1, even with the winding technique described here with 24/43 • ···· ··· a plurality of winding wires 5 and layer winding regions 6 are produced.
