    A permanent magnet motor includes stator means (52), rotor means (54) and electronic control means (56). Each stator means includes permanent magnets (90, 92) having pole faces (152, 154) that define a gap (102) between them with a generally uniform magnetic flux density thereacross. Each gap (102) has an entrance section, an exit section and a generally curved longitudinal path extending from the entrance section to the exit section about the rotor axis (63). The magnetic flux density changes as one moves from the entrance section to the exit section as a function of arc degree position around the rotor axis. Each rotor means includes a predetermined number of permanent magnets (116) disposed radially outwardly from the rotor axis (63). These rotor magnets are disposed within the gap (102) and the magnet field of each rotor magnet interacts with the magnetic field of the associated stator magnets through repulsion or retraction. The electronic control means (56) induces an electromagnetic field that interacts with a magnetic field of a rotor magnet (116) or the stator magnets (90, 92) selectively to enhance or retard the rotational speed of the rotor (54).

    The invention relates to electrical engineering, namely, electric motors with an electronic switch.
    The aim of the invention is to simplify the design and reduce the cost of manufacture.
    Figure 1 shows the isometric projections of two flat and parallel stator magnets and a rotor located between them; Fig.2 is an end view of one of the engine variants; in FIG. 3, a motor, a top view and a horizontal section; Fig. 4 is a section A-A in Fig. 3 (some of the parts have been omitted for simplicity); on fig.Z - section bb in fig, 4; figure 6 - section bb In Fig, 4; 7 is a block diagram of an electronic switch; FIG. 8 is a block diagram of a portion of the timing chain of the electronic switch; FIG. figure 9 is a block diagram of an electromagnet and an electromagnetic controller, one option; FIG. 10 is the same, another variant.
    The electric motor contains (Fig. 1) permanent magnets 1 and 2 of the stator, which are slightly inclined towards one another and oriented so that their opposite poles are facing each other. Each of them is a rectangular prism of a predetermined length. The magnets are held in a fixed spatial position, which defines the gap 3 with the longitudinal axis 4. The gap has a narrower entrance section 5 and a wider output section 6.
    The rotor 7 in the form of a permanent magnet is a triangular prism located inside the gap 3. It has a narrower (circumferentially) end 8 located closer to the output section 6 of the gap and a wider end 9 located closer to the entrance section 5 of the gap . The two non-parallel rectangular faces are the opposite magnetic poles N and S, which are repelled by the poles N and S of the permanent stator magnets, respectively. The triangular configuration of the constant magnet section of the rotor increases the difference in distance from the rotor magnet to the stator magnets measured at opposite ends 8 and 9 of the rotor permanent magnet. Since the distance from the permanent magnet

    the rotor to the stator pole in section 6 is larger than in section 5, the difference is repulsive, their forces lead to the appearance of a force F, which tends to accelerate the rotor magnet along the longitudinal axis 4 towards the output section 6 of the gap. The shape of the rotor 7 shown in Fig. 1 can be replaced with a rectangular prism. This will reduce the difference in distance from the rotor ends to the corresponding stator poles, which will reduce the resulting force, however, due to the difference between these distances, obtained by tilting the stator magnets, the rotor magnet will still accelerate along the longitudinal axis 4 .

    The inclination of the stator magnets and the triangular section of the rotor magnet can be used both simultaneously.
    The electric motor (Fig. 1) creates linear displacements.
    When the gap between the permanent magnets of the stator is formed in the form of a ring section, the electric motor around the axis of rotation will create a rotational movement of the rotor.
    Although the operation of an electric motor has been described taking into account magnetic repulsive forces, it should be taken into account that the forces of attraction can also be used, as well as a combination of the indicated forces.
    Figures 2-4 show one of the embodiments of the invention, the same parts being denoted by the same positions. The Danny version contains two stator and rotor assemblies mounted on a single common shaft. It should be noted that one or more stator and rotor assemblies can be used and the number of rotor magnets can vary according to 5 desires or necessities. When the plurality of stator-rotor assemblies are paired, the stators can be rotated 180, as shown in Figures 2 and 3. This allows electro-Q magnets to be built in and minimizes torque pulses to smooth the shaft rotation.
    A permanent magnet motor 10 contains three main parts. The stator means 11 contains at least a pair of opposed permanent magnets which define a gap between them. The means of the rotor 12 contains a predetermined count

    honestly permanent magnets mounted for rotation in this gap. The electronic control means 13 comprises an electromagnet which induces an electromagnetic field, interacting with the magnetic field of the rotor and the stator, to control the rotation of the rotor.
    The stator 11 (FIGS. 4 and 5) contains a pair of magnet holder 14 and 15 located opposite each other, made of a non-ferromagnetic material. Each magnetic holder has a T-shaped shape and has first and second ends 16 and 17. The C-shaped shape also defines a central longitudinal axis 18, which is the same for the two magnetic holders. The outer surface of the stator 19 (Fig. 4) can have a flat or any other suitable configuration, and the inner surface of the stator 20 forms a spiral segment, where the first and second ends 16 and 17 are axially spaced apart from each other by a predetermined height. . This form is similar to the usual Grover washer. The annular rim 21 protrudes axially from the inner surface of the stator 20 along its inner circumference 22, forming a shelf on which the stator magnets rest. This magnet holder 14 can be attached to a frame 23 made of a non-magnetic material to preserve the axial alignment and spatial position.
    The second or opposite magnet holder 15 is a mirror reflection of the magnet holder 14, which is axisymmetric with respect to a plane perpendicular to the longitudinal axis 18 and located midway between the two magnetic holders. The magnet holder 15 can be attached to a frame element 24 filled with a non-magnetic material in the same way as the magnetic holder 14. On the frame elements a pair of coaxial bearings spaced apart from FRIEND bearings 25 and 26 can be placed to support the rotation of the shaft 27 coinciding with the longitudinal axis 18. The frame elements can be attached to the non-magnetic base 28, if necessary, or at will, and can assemble lateral supports 29.
    A pair of C-shaped permanent magnets 30 and 3 of the stator, the shape of which is responsive to the spiral inner surface 20 of the magnetic holders 14 and 15, is attached to these magnetic holders, and the magnets have a uniform axial thickness and are magnetized throughout the thickness so that the opposite poles face to each other through the gap between them. In addition, ferromagnetic plates 32 and 33 having a similar C-shape, made of a material with high magnetic permeability, can be installed between each of the stator magnets and the corresponding magnetic holder to create. parts of magnetic flux former. In addition, a material with a high magnetic permeability can be used in other places to give the desired shape to the magnetic flux and to improve the desired performance. For example, it can connect the outer pole faces of the permanent magnets of the stator in order to bridge the gap and reduce the resistance of the magnetic circuit between them.
    The inner opposite faces 34 and 35 of the permanent magnets 30 and 31 of the stator define a curved C-shaped gap 36 having an input portion 37 (figure 5) located adjacent to the end 17 of the magnetic carrier and an output portion 38 located next to the end 16 magnet holder This gap has a constantly increasing width with a uniform gradient measured axially between the opposite faces 34 and 35 of the stator magnets when moving along the gap from the input section to the output. Although the magnetic holders are described as having an uneven axial thickness that provides a spiral shape, and the magnets - as having the same thickness, it should be noted that these dimensions can be changed, provided that the gap for this embodiment of the invention has a constantly increasing distance between E n when moving from the inlet to the outlet portion. It should be noted that the same basic design can have a gap with a constant distance between
    faces and a permanent rotor magnet with a triangular cross section.
    The rotor 12 (Fig. 6) is rotatably mounted on the shaft 27, which is located coaxially with the axis 18. The said rotor comprises a circular plate 39 made of a non-magnetic material and having a hub and an annular collar circumferentially. A predetermined number of permanent magnets 40 are located radially at equal angular distances from each other (six magnets are shown in the drawings, but this number may vary). A plurality of clamps of non-magnetic material 41 interact with the hub 42 (FIG. 4) and circumferentially: shoulder for clamping between them a section of the rotor magnet with the possibility of its release, for which a screw 43 or other fastening element is used. A keyway can be made in the hub 42 of the rotor, connecting it with the shaft 27.
    In Fig. 6, the permanent magnet of the stator 30 is shown behind the permanent magnets of the rotor 40 and occupies about 300 arcs around the longitudinal axis 18 for a rotor having six magnets. The angle A measured between the ends 44 and 45 of the stator permanent magnet should be approximately equal to the angle B between the centers of the adjacent rotor magnets, measured in the plane perpendicular to the longitudinal axis. For example, if there are 10 rotor magnets, ANGLE A would be equal to 36.
     Each rotor magnet has an upper part 46, made in the form of a curved triangular prism, and a lower part, embodied in the form of a curved rectangular prism. The lower part may contain protruding shoulders or grooves that complement and interact with the collar on the hub 42 of the rotor. The upper part of the permanent magnet of the rotor has a narrow end, a wider rear end and flat rectangular side faces 47, inclined one to the other. Then the 1st magnet of the rotor is magnetized over its entire thickness so that the north and south poles occupy the corresponding face. When mounted on the rotor hub, the rotor magnets are oriented so as to push away from the faces of the stator threads defining the gap 36, and the narrow end of the rotor faces the direction of rotation, the entrance to the entrance section of the gap before it enters the wide rear end. The rotor magnet can be magnetized with opposite polarity in order to use the force of attraction rather than repulsion. Figures 2 to 4 show an electronic control means comprising a CO-shaped electromagnet 48, opposite poles 49 and 50 of which define an air gap between them. The poles 49 and 50 of the electromagnet are located between the first and second ends
    5 16 and 17 C-shaped stator magnets so that they are on opposite sides of the rotor magnets. The thickness of the air gap in the direction of the axis 18 approaches the axial thickness
    0 of the entrance section of the gap 36. Preferably, for each rotor-stator assembly, a separate electromagnet and holes defined by the stator magnets are used along with the associated
    5 electromagnets for each node, rotated 180 relative to each other to limit the interaction between them and to limit the induced currents, to smooth the rotor.
    The tachometer tool 51 causes the electric circuit 52 to generate an electrical output signal in response to the rotational speed and the angular position of the shaft 27. This output signal is transmitted to the electronic means, where it is processed to control the electromagnet 48, and the Q causes it to direct or remove a magnetic field. between poles 49 and 50. Energy for the operation of an electromagnet can be obtained from pulmonary sources.

    A pair of opposite C-shaped
    permanent magnets of the stator, has the form of a spiral, with one permanent magnet of the stator enclosed in another.
    Q a are not axisymmetric mirror images of each other. Such an electric motor version contains a stator defining a longitudinal axis, a rotor mounted with the possibility of rotating around this longitudinal axis and an electronic control means.
    Consider the block diagram of the electronic switch shown in Fig.7.

    The electrical circuit 52, being the sensor in FIG. 3, generates an output impulse to line 53 in response to the rotational speed and angular position of the shaft 27. The output impulse along the line 53 is fed to the impulse driver 54 to provide uniform voltage and duration pulses line 55. Although the shaper 54 pulses are not obscured in this chain, but it improves the stability and uniformity of work. Speed indicator 56 can be connected to pulse generator 54 in a known manner, for example, via line 57, to provide a direct indication of the speed of rotation of the engine. The output of the pulse driver is supplied via line 55 to the electronic timing control circuit 58, which can delay the output signal of the pulse driver 54. Such a delay can be obtained mechanically by changing the position of the sensor or the electric circuit 52. The time-adjusted signal is fed to lines 59 and 60. The frequency speed comparator compares the difference between the signal in line 61 from master clock 62, the signal in line 59 from electronic control circuit synchronization and raises the proportional signal to line 63, this signal being an error signal. The electromagnetic controller 64 supplies electrical pulses of a predetermined magnitude and with a predetermined delay to the electromagnet 65 via line 66 in response to input signals from the frequency comparator 67 of the rotational speed and the electronic timing adjustment circuit. The balance value of resistance, capacitance and inductance in the electromagnetic controller can achieve synchronous operation. At first, the electromagnet attracts the rotor magnet when it approaches the center of the air gap of the electromagnet, and then changes the polarity of its magnetic field to repel the rotor magnet when it leaves the center of the air gap of the electromagnet.
    The sensor may be one of many types of sensors that output a signal, preferably digital in response to the rotational speed of the rotor.

    Torah. It can determine the rotor speed in any known manner, for example using a magnetic sensor, an electromagnetic eddy current sensor, an infrared optical sensor, or a mechanically coupled sensor. For the proposed engine, six pulses per 360 revolutions, i.e. one pulse for each rotor magnet.
    Pulse shaper 54 produces an output pulse of uniform voltage and period in response to an input pulse from a sensor or electric
    circuit 52, the output pulse corresponding to predetermined threshold specifications for the electronic timing adjustment circuit. . The shape of the output pulses in line 55
    does not depend on the shape of the input pulses From line 53.
    The rotational speed indicator 56 may be any suitable and joint frequency indicator.
    The electronic timing adjustment circuit 58 provides the ability to selectively vary the power supply time to the electromagnet 65. FIG. 8 shows that the signal from the pulse driver 54, which is detected along the line 55, is multiplied, for example, by a factor of twenty times frequency multiplication and fed ten times
    Counter 69 on line 70. Counter
    69 produces in line 71 twenty binary pulses for each pulse received from the imager 54 pulses. The decoding device 72 converts binary counting pulses into pairs of tens. The first impulse of the tenth controls the electromagnet for the first rotor, and the second impulse of the tenth controls the electromagnet for the second
    rotor, with the electromagnets separated by half phase or 180, as shown for two-rotor motors in FIGS. 3 and 4. Therefore, it is possible to delay the supply of electromagnets from 0 to 50% by adjusting the contact 73. The output signal on line 74 is supplied a trigger 75, which alternately feeds the output signal of the electronic timing control circuit to two electromagnetic controllers via drivers 76 and 77 pulses. Another means of multiplying the frequency is to use a frequency converter and voltage converter, a twenty-fold amplifier, and another integrated circuit used as a voltage-to-frequency converter.
    The output of the electronic timing control circuit is compared with the output of the master clock generator 62 using the engine speed comparator 67. The input signals from lines 59 and 61 are converted to an output signal fed to line 63 and is proportional to the difference between the actual rotor speed and the desired rotor speed.
    The output of comparator 67 is supplied to electromagnetic controller 64 via line 63, as the output of circuit 58 of the electronic timing control. This controller supplies energy to the electromagnet 65 and controls the efficiency of the electromagnetic field, changing the time of applying electrical energy to the electromagnet relative to the angular position of the rotor magnets, and also changing the amplitude of the electrical impulse that the electromagnetic field generates.
    FIG. 9 shows an amplifier 78, with an input line 63. The output of amplifier 78 is provided via line 79 to the base of transistor 80, connected in series with DC source 81 and smoothing capacitor 82. Together they form a voltage regulator. Any suitable voltage control circuit may be used. The discharge of capacitor 82 is selectively blocked by silicon controlled mitters 83-84. The rectifier 83 is normally off or in a non-conducting state, allowing the capacitor 82 to be charged, which switches to a conducting state in response to the switch circuit signal 85.
    The signal from the electronic synchronization control circuit 58 is applied to a pulse generator 86 with a time delay controlled by the voltage through a clock 87. After Togo, as on the potentiometer 87, the voltage reaches a threshold value, which includes a pre-selected delay in the pulse generator 86 the pulse output is fed to lines 88 and 89. Therefore, the opening circuit has two sources of delay — manual

    the setting of the potentiometer 87 and the automatic adjustment of the frequency and rotation speed from the comparator 67 is instantaneous. Pulse output on the line.
    88 is applied to the base of the transistor 90, causing it to go into a conducting state and apply a sufficient trigger voltage to the valve 83, putting it into an on or conducting state. Elements 91-94 operate with a transistor 90 or filter the signals.
    Charged capacitor 82 is charged through rectifier 83 and energizes a balanced circuit of resistivity, capacitance and inductance, which is represented by capacitor 95 and electromagnet 96 to create an electromagnetic field at the electromagnet poles located on opposite sides of the rotor (Fig. 3) and the attraction (or repulsion) of the rotor magnet. After the electromagnetic field reaches its peak, it decreases, charging the capacitor 95 connected to the terminals of the electromagnet, to reverse the electromagnetic field. This will repulse (or attract) the rotor magnet in synchronism with its rotational movement for insertion between the stator magnets. The synchronization circuit determines the moment of energizing the electromagnet, which in turn determines whether the electromagnet will attract or repel the rotor magnet.
    The rectifier 83 is turned off or transferred to the non-conductive state by the shutdown circuit 97. Delayed output of the generator 86 pulses on the line
    89 controls trigger 98, the output of which passes through amplifier 99.
    to the switching circuit 97. The predetermined time constant is set by potentiometer 100 and capacitor 101, each of which is connected between the emitter junction and the base of the single-contact transistor 102 in the usual way. When the time constant is held, the single-contact transistor 102 transits to the conduction state of the rectifier 84, which grounds the capacitor 103, switching the voltage to the rectifier 83 and zero, and thereby turning it off. Resistors 104-106 work in conjunction with transistor 102.,

    Various modifications may be made to the design corresponding to the electronic control circuit. The adjustment of the temporarily constant for the generator 86 pulses and the switching circuit 97 and the adjustment of the active-inductive-capacitive circuit for the electromagnet 96 depend on the desired optimum engine performance. The electromagnet can optionally be i-or C-shaped. In addition, you can use digital or analog circuits, their combination or a microprocessor.
    Figure 10 shows an alternative embodiment of an electromagnet and an electromagnet control circuit. Electromagnet 107 is electrically connected to a constant voltage source 108 via a normally open relay 109, which, when energized, closes the switch 110. The relay is powered by an electrically isolated circuit containing an electromagnetic coil 111, a constant voltage source 112 and a sensory switch. the switch can be actuated by a cam and is placed in a position similar to that shown in FIG. 3 for electrical circuits 52. Resistor 114, capacitor 115 and diode 116 balance the electromagnet nit 107.
    The engine works as follows.
    For the initial position of the rotor, conditionally accepted is the position in which the rotor magnet is fully inserted into the entrance section of the gap. The radial distance from the edge of the rotor magnet to the edge of the stator magnet is greater at the narrow front end of the rotor magnet than at its wide rear end. Since the repulsive forces generated by the opposite magnetic fields of the rotor — the stator as a whole, are inversely proportional to the distance, a resultant force arises, tending to move the rotor magnet towards the front end and a constantly widening gap. Each rotor magnet in the gap contributes to the creation of a force that tends to rotate the rotor, and the rotor magnets move from the inlet portion of the gap to the exit portion.
    When the rotor magnet comes out of the exit gap and continues
    12
    movement towards the entrance of the gap, it is affected by the repulsive force of the entrance of the gap. If the rotating force is generated
    the magnets in the gap are sufficient to overcome the repulsive forces that prevent the rotor magnet from entering the gap, the rotation will continue. If the rotational force generated by the magnets located inside the gap is insufficient, then an electromagnetic means can be used to create a magnetic field that will tend to introduce a magnet.
    rotor in the entrance area of the gap. Synchronously with rotation, as determined by the tachometer, the electrical circuit induces a magnetic field to attract the rotor magnet when
    out of the exit section of the gap. Preferably, the previous rotor magnet is essentially inside the entrance section of the gap, so that the repulsive action of the electromagnetic
    a floor on this magnet would be insignificant. When the attracted rotor magnet approaches the middle of the gap between the poles of the electromagnet, the attracting field is removed and reversed to push the rotor magnet, it rushes into the entrance section of the gap. This synchronized field reversal has a pushing effect on the rotation of the rotor, which enhances this rotation.
    In addition, the repulsion of the incoming rotor magnet can be balanced by the forward directed force of the rotor outgoing magnet, thereby reducing the negative force that the incoming rotor magnet experiences. This increases the output torque and smooths out torque fluctuations.
    Similarly, electromagnetic means can be used to slow down or stop
    rotation changes the magnetic field intensity, or its polarity changes. The speed or power output of the magnetic motor can also be changed by changing the distance between
    faces of magnets, stator. The closer they are to the rotor magnet, the greater the magnetic forces between them will be and the higher the output power will be. On the other hand the engine
    13 . You can stop the section of the half of the stator.
    Alternatively, the motor can operate using attracting forces by reversing the field of the rotor magnets and the polarity of the electromagnet means. Another alternative is to use an independent energy source to rotate the rotor and use this device as a generator. The motion of the magnet between the poles of the electromagnet will induce a current and additional windings can be placed along the stator circumference, connecting, for example, the outer surfaces of the stator magnets with a material that has magnetic permeability and is surrounded by an electrical winding.
