Definitions
- Wind power generation system arrangement structure of permanent magnets and electric power conversion equipment
- the present invention relates to a wind power generation system, an arrangement structure of permanent magnets, and an electric power conversion device. More specifically, the present invention relates to a wind power generation system that employs a linear motor as a generator as a generator, a permanent magnet arrangement structure and an electro-power conversion device that can be suitably employed in the wind power generation system.
- the term “electricity-to-power converter” refers to a device with a power generation function that converts mechanical energy into electrical energy and a motor (motor) that converts electrical energy into mechanical energy. It is a concept that includes both equipped devices and devices that perform both functions by operation.
- Patent Document 1 Japanese Patent Publication No. 3-10037 discloses that an impeller shaft is connected to a ring gear, and the impeller shaft is connected to the ring gear through a plurality of planetary gears inscribed therein.
- a wind power generator is disclosed in which a concentrically arranged sun gear is rotated and a shaft of the sun gear is connected to a generator.
- These ring gear, planetary gear, and sun gear constitute a planetary gear reducer, and the rotation of the impeller connected to the ring gear is increased in speed by the reducer and transmitted to the generator.
- the generator can be operated efficiently even when the rotation speed of the impeller is low due to weak wind power.
- Patent Document 2 Japanese Patent Application Laid-Open No. 2001-132617
- Patent Document 2 Japanese Patent Application Laid-Open No. 2001-132617
- a wind power generator in which wind receiving surfaces of upper and lower impellers are opposite to each other. Regardless of the direction in which the wind blows, the upper or lower impeller receives the wind strongly, so that it can generate power efficiently. Further, it is disclosed that the impeller is lifted by the repulsive force of a magnet and rotated with low friction.
- Patent Document 1 Japanese Patent Publication No. 3-10037
- the wind used by the wind power generation device is a natural phenomenon, and varies considerably from a weak wind state to a strong wind state. Therefore, wind power generators are required to be able to respond quickly to such fluctuations.
- Conventional wind power generators have adopted generators capable of coping with a wide range of rotation speeds in order to cope with such wide-range fluctuations of wind power. Not converted.
- the wind power generator of Patent Document 1 described above is intended to obtain an efficient speed-up effect by inputting the light to the ring gear, which is the output side of the planetary gear reducer, and outputting the light from the sun gear side. In this state, the torque is insufficient and the motor stops. Therefore, power cannot be generated until a strong wind that exceeds the static friction resistance starts to blow. Further, since it is necessary to transmit the torque from the peripheral vertical blades to the center axis using a support rod or the like, the weight of the impeller increases. Therefore, it is more difficult to rotate in light wind.
- An object of the present invention is to provide a wind power generation system capable of efficiently generating power without stopping the rotation of the impeller even in the case of a breeze that would stop with a conventional device. Further, the present invention has a technical problem to provide an electric-power converter suitably used for such a wind power generation system.
- the wind power generation system of the present invention is arranged on a frame, an impeller rotatably supported by the frame, and one of the impeller and the frame at an equal distance from the rotation center of the impeller.
- a plurality of field magnets (magnetic field magnets) and a group of coils arranged in a ring on the other side, and the field magnet and the coil group move relatively close to each other.
- the field magnet may be a permanent magnet or an electromagnet.
- the field magnets are arranged in an annular shape in the vicinity of the outer peripheral portion or the intermediate portion of the impeller, and a ring-shaped magnet is provided at a position close to the coil group in the frame. It is preferable that the above-mentioned coil group is attached to the ring-shaped member. It is preferable to provide the field magnets at intervals in the circumferential direction.
- a ring-shaped member force to which the coil group is attached is provided in a pair so as to sandwich a field magnet that is annularly attached to the impeller, and one coil group and the other coil group are provided. It is provided with a plurality of coil groups that are alternately or cyclically arranged so as to generate an alternating current.
- a coil group having one specific phase and another coil group having a phase corresponding to the phase are provided.
- the one and other coil groups each include a first coil group, a second coil group, and a third coil group that are cyclically arranged so as to generate three-phase alternating current, It is preferable that one of the first coil groups is displaced from each other so as to face the other second or third coil group.
- a ring piece having a predetermined length made of a core made of a plurality of metal layers, the coil group also having a wire force wound around the outer periphery thereof, and a synthetic resin for integrally solidifying the core. are preferably connected in a ring shape.
- a wind power generation system in which an annular supporting means for supporting at least a part of the weight of the impeller while allowing rotation of the impeller is interposed between the outer peripheral portion or the intermediate portion and the frame is preferable.
- Such support means is provided on one of the frame and the impeller, and is provided on a rolling element group or a sliding element group, and on the other, a traveling path that comes into contact with the rolling element group or the sliding element group.
- the support means includes a first magnet group provided on the frame and a second magnet group provided on the impeller so as to repel each other with the magnet groups. It can also be configured with power.
- the first magnet group is arranged in a ring substantially continuous with a frame, and the impeller has a plurality of blades arranged radially.
- the second magnet group is radially arranged so as to support those blades.
- the wind power generation system includes a gap adjusting means for adjusting a gap between the plurality of field magnets provided in the frame and the impeller and the coil group.
- the support means comprises an annular guide centered on a rotation center on one of the frame and the impeller, and a slider provided on the other and running along the guide.
- a second aspect of the wind power generation system of the present invention includes a frame, an impeller rotatably supported by the frame, and a generator that generates power by rotation of the impeller.
- One of the impellers is provided with an annular guide centered on the center of rotation, and the other is provided with a slider that runs along the guide.
- the guide and the slider be constituted by a guide and a slider of a linear slide ball bearing.
- the annular guide has smooth cylindrical guide surfaces on an inner surface and an outer surface, and the slider includes a guide roller that rotates about a vertical axis and rolls along the guide surfaces. Is preferred. Also, the center of rotation of the impeller faces in the horizontal direction! Of course, you can go straight in 10 directions.
- a first aspect of the electric power conversion device of the present invention includes a moving element and stators disposed on both sides of the moving element, and a pair of an N pole and an S pole is provided on both surfaces of the moving element.
- the configured magnet parts are arranged along the circumferential direction of the mover such that the N pole and the S pole and the S pole and the N pole are alternately located.
- adjacent magnets are connected by a non-magnetic metal body.

- the wind power generation system 10 shown in FIG. 2 includes a frame 11 and impellers 12 provided in two upper and lower stages in the frame, and the impeller 12 is arranged around an axis perpendicular to the frame 11. It is provided to be rotatable.
- a power generation unit (a so-called linear generator) 14 is provided between the lower end of the impeller 12 and the ring 18 of the frame 11 to generate power by an operation reverse to the operation of the linear motor.
- the frame 11 includes three legs 15 extending vertically and a connecting member 16 connecting the legs at equal intervals in the circumferential direction.
- the connecting members 16 are provided at the upper end of the leg 15, at a position slightly above the lower end, and at three intermediate stages.
- the impeller 12 is accommodated in the spaces Sl and S2 between the connecting members 16.
- the connecting member 16 includes three spokes 17 extending radially, and the above-described ring 18 that connects the spokes 17 near their outer ends. Further, a pair of upper and lower bearings 19 and 20 for rotatably supporting the impeller 12 are provided at the center of the spoke 17 of each connecting member 16.
- the impeller 12 includes a shaft 22 that extends in a vertical direction, and a shaft 22 that extends in the vertical direction.
- the upper ends and the lower ends of the vertical blades 26 are connected to each other by reinforcing rings 21 and 21 attached to their inner circumferences, thereby improving the strength of the entire impeller 12. However, the reinforcing ring 21 need not be provided.
- the horizontal blade 25 has an airfoil shape having a cross-sectional shape such that buoyancy acts upward when the shaft 22 rotates counterclockwise when the upward force is also viewed.
- a specific airfoil and a specific inclination that may be inclined so that the front end is directed upward with respect to the rotation direction may be combined. Further, the inclination may be adjusted.
- the number of the vertical blades 26 may be about three, or may be ten or more. As shown in the imaginary line, the upper and lower shafts 22 of the impeller 12 may be connected to each other to form a single shaft penetrating vertically.
- the vertical blades 26 have an airfoil shape such that when receiving wind from the lateral direction, the resultant force of the five vertical blades 26 generates a counterclockwise moment when the resultant force also looks upward. ing.
- the vertical blades 26 may also be tilted around the vertical axis, or a combination of the airfoil and tilt. Further, the inclination may be adjusted.
- the upper end and the lower end of the shaft 22 of each impeller 12 are rotatably supported by an upper bearing 19 and a lower bearing 20, respectively.
- the weight of the impeller 12 is basically supported by the lower bearing 20.
- it can be supported by wheels, magnetic levitation, or the like.
- it is supported by the lift generated by the horizontal blades 25 as it rotates.
- a wheel 27 is rotatably attached to the lower end of each vertical blade 26.
- a portion inside the ring 18 of the frame 11 forms an annular traveling path 28. Therefore, all or part of the weight of the vertical blades 26 and the horizontal blades 25 is supported by the frame 11 via the wheels 27. Therefore, the burden on bearings 19 and 20 is small. Further, since the radius of the horizontal blade 25 is reduced, the operation of the power generation unit 14 is stabilized. Furthermore, since the radius is small, the rotation is stable even when the entire impeller 12 is made of a lightweight material such as foam, resin, or fiber-reinforced plastic.
- the power generation unit 14 includes a field magnet made up of a permanent magnet 31 provided near the lower end of the vertical blade 26 of the impeller 12, a coil group 32 provided on the ring 18 of the frame, and FIG. And a power storage unit 34.
- the coil group 32 is covered by an annular cover 38 as shown in FIG.
- the field magnet may be a permanent magnet or an electromagnet. Installation work and maintenance are easy because no wiring is required for permanent magnets. However, in the case of large-scale wind power generation systems, electromagnets are easier to handle and have advantages. Similarly, in the following embodiments, the deviation of the permanent magnet or the electromagnet can be adopted as the field magnet.
- the coil group 32 is composed of a first coil row 35, a second coil row 36, and a third coil row 37, which are arranged in a set of three.
- the ends of the coils of the respective coil arrays 35, 36, 37 are connected in parallel to a first transmission line 41, a second transmission line 42, and a third transmission line 43 for extracting electric power.
- they can be connected in series.
- each of the power transmission lines 41, 42, and 43 may have a common power ground wire.
- Each of the transmission lines 41, 42, and 43 is guided to the control unit 33, and can be transmitted to the outside by an external transmission line 45.
- the coils of the coil group 32 are arranged at substantially equal intervals.
- the space between the permanent magnet 31 and the coil provided on the lower end outer surface of each vertical blade 26 is sufficiently close to each other, and the distance S3 between the permanent magnet and the coil is, for example, about 115 mm.
- Each coil of the coil group 32 may or may not include an iron core.
- the impeller 12 rotates in the counterclockwise direction (the arrow P1 in Fig. 1) when the upward force is also observed. Since the lines of magnetic force of the permanent magnets sequentially cross the coils of the coil group 32, an electromotive force is generated in the coil by the operation opposite to that of the linear motor, and the power at both ends can be extracted. In this embodiment, Is generated in order by three sets of coil arrays 35, 36, 37, so that power is generated in the form of three-phase alternating current. The obtained electric power is transmitted to the control unit 33 via transmission lines 41, 42, and 43. In the control unit 33, the power pulsation is flattened, or the power is transmitted to the outside in a three-phase alternating current state combined with a clean sine curve. At that time, part of the electric power is stored in the power storage unit 34.
- the permanent magnet 31 is provided near the outer periphery of the impeller 12, so that the inertia of the impeller becomes large. Then, even if the wind power changes to a stop, the rotation speed is unlikely to change. Therefore, stable power generation can be performed. Further, the vertical blades that generate rotational force in response to the wind and the power generation unit 32 that becomes a load due to the reaction of power generation are both tangential to the outer circumferential circle of the vertical blades 26. Therefore, the strength which does not need to transmit the torque by the horizontal blades 25 may be low. Accordingly, the impeller 12 can be made of a lightweight material such as a foamed resin molded product or a fiber-reinforced plastic. Therefore, the power generation efficiency is high with less resistance to rotation.
- the control unit 33 switches the connection state of the power transmission line 46 connected to the power storage unit 34, and transfers power from the power storage unit 34 to the coil group 32. It is preferable to provide the supply.
- the power generation unit 14 acts as a linear motor, and can rotate the impeller 12 in the same direction. Therefore, the impeller 12 does not stop and continues to rotate at a later time. Since power cannot be generated during that time, stop power transmission or transmit power from the power storage unit 34. Then, when the wind starts to blow again, the transmission line 46 of the control unit 33 and the power storage unit 34 is returned to the original state, so that power is generated.
- the blades are not stopped, it is not necessary to rotate the stopped state force by using the static friction force as in the case of starting rotation. Therefore, efficient power generation can be performed without wasting power as a whole.
- the switching between the motor operation and the power generation operation is performed automatically, for example, by providing a sensor for detecting the rotation speed and determining whether the rotation speed has decreased or has increased from a predetermined reference value for the rotation speed. You can do it!
- the coil groups may be divided into, for example, four groups so that the power can be extracted from any of the groups or selected by turning the circuit breaker on and off. In that case, since the rotation load of the wind impeller 12 can be changed, it is possible to control so as to generate power with a small number of coils in a light wind state and to increase the number of coils to be generated when the wind power recovers. As a result, efficient power generation can be performed over a wide range of wind power.
- the number of coils to be operated can be increased or decreased by one for each group, or can be two or three.
- it can be driven as a motor with other coils.
- wheels 27 are attached to the lower ends of the vertical blades 26, and a running path 28 is provided on the side of the frame 11.

Further, even if a directional force is applied to the center on the rotating side, the inner magnet 90b and the vertically-oriented permanent magnet 89 repel, so that a force corresponding to the above force is generated. Conversely, even when a force that acts outward is applied, a force that tries to restore the force is applied between the outer magnet 90c and the vertical permanent magnet 89.

- the rotor 127 of the generator having two stators 131 on both sides of the rotor 127 is a donut-shaped rotor that is circumferentially distributed.
- the difference between the inner and outer diameters of the rotor 127 is small to reduce the size of the stator 131, and the weight of the rotor 127 is light to reduce the bearing load of the rotor 127. Is required.
- FIG. 29 shows the structure of the rotor yoke 132 of the generator having the stator 131 on one side. Elements having functions similar to those in FIG. 28 are denoted by the same reference numerals.
- permanent magnets 126 are arranged alternately with N poles and S poles, and arrows indicate magnetic flux.
- the rotor 127 of the generator having the stator 131 on one side requires a magnetic circuit made of iron to facilitate the passage of magnetic flux between the N pole and the S pole.
- the width of the magnetic circuit of the rotor 127 is half the width of the magnetic pole (the width of the permanent magnet 126).
- stator 131 is a generator on both sides of the rotor 127 and the rotor 127 having magnetic poles (permanent magnets 126) on both sides is configured, as shown in FIG. Therefore, a rotor yoke 132 having a large width is required.

A gap is provided between the magnet 134 and the other end of the magnetic body 135. Generally, the magnetic flux density B of the air gap generated by the permanent magnet 134 is
- the magnetic attractive force is larger than that of the generator having the magnetic poles (permanent magnets 126) on only one side of the rotor 127.
- the problem with the idea of this structure is that the weight of the rotor 127 is heavy and the magnetic attraction force when the shaft is eccentric is large. That is, it has the configuration of the rotor 127.
- the rotor yoke part 132 which is required twice is provided. Reduction of the width of the rotor yoke 132 and sharing of the rotor yoke 132 can be considered.
- This reduction in the width of the rotor yoke portion 132 increases the magnetic resistance of the rotor yoke portion 132, reduces the ability of the permanent magnet 126, and reduces the magnetic attraction force. It doesn't solve the problem of being big.
- the rotor yoke portion 132 is shared by shifting the positions of the outer magnetic pole and the inner magnetic pole of the rotor 127 by half of the pole pitch of the magnetic poles, which is effective in reducing the weight.
- the outer and inner magnetic poles move independently, which does not solve the problem of high magnetic attraction.
- magnet parts 137 which are a pair of N-pole and S-pole magnets 136, 136, are circumferentially arranged at equal intervals so that the N-pole and S-pole of the magnet part 137 are alternately located on opposite sides.
- stators 131 are disposed on both sides of the rotor 127.
- the same magnetic force lines pass through the magnet portions 137 on both sides of the rotor 127 and the stators 131 on both sides, so that the magnetic flux densities in the air gaps on both sides become the same, and the magnetic attraction force becomes the same. .
- FIG. 34 shows a state obtained by modeling this state.
- the magnetic flux density of both poles in this model is as follows. Since the two magnets (magnet part 137) are on the same magnetic circuit, The magnet thickness and air gap are added together,
- the magnets 136, 136 on both sides of the rotor 127 are paired with an N pole and an S pole, and a single magnetic circuit is provided.
- the magnetic poles adjacent to each other can be connected by the non-magnetic metal body 138, so that the rotor 127 can be magnetically attracted even if the axis of the rotor 127 is eccentric, without the need for a conventional iron magnetic circuit.
- the effect is that no force is generated in the calculation.
- there is an operational effect that a rotor yoke between circumferentially adjacent magnetic poles is not required, which is required in the rotating machine having the above-described structure.
- FIG. 35 shows a specific embodiment.
- a stator 131 on each side of the rotor 127, and the rotor 127 is mounted on a non-magnetic metal body 138 with N-pole and S-pole magnets 136, 136 provided all around. It is. Magnets adjacent to the rotor 127 in the circumferential direction
- the non-magnetic metal member 138 connects between 136 and 136 (magnet part 137).
- the magnets 136, 136 on both sides of the rotor 127 are connected by magnetic metal instead of the non-magnetic metal body 138, the magnetic resistance between the magnets 136, 136 on both sides decreases.
- the magnetic attraction generated by the magnets 136, 136 on both sides of the rotor 127 is the same.
- the magnetic flux generally has the property of spreading in space to reduce the magnetic flux density, and since the stator 131 exists in the circumferential direction, the constant k of the magnetic pole area in the above equations (6) and (7)
- K increases on the near side and decreases on the far side. For this reason, the magnetic attraction on the near side becomes larger than on the far side.
- FIG. See Figure 36 the calculation results of the magnetic attractive force by the magnetic field analysis using the finite element method of the magnetic attractive force including the secondary phenomenon are shown in FIG. See Figure 36.
- This calculation is based on the assumption that the magnet dimensions and air gaps on both sides in Fig. 32 and Fig. 35 are the same, and the iron rotor yoke between adjacent magnetic poles in the circumferential direction in Fig. 32 is half the magnet width. It is. As shown in these results, the magnetic attraction force of the structure shown in FIG. 35 is smaller than that of the conventional structure.
- the magnets 136 on both sides operate on the same magnetic circuit, and the eccentricity of the rotor 127 is reduced. Even if it occurs, the magnetic attraction of the magnets 136 on both sides is balanced and the force becomes zero in the entire rotor 127, and the generation of the force for further moving the rotor 127 is eliminated in the calculation.
- the magnets 136 and 136 are mounted on the same magnetic circuit, the rotor yoke between adjacent magnetic poles, which is required in the conventional structure, is not required, and the weight of the rotor 127 can be reduced and the rotor 127 can be used.

- rotors 151 of the generator having stators 152 on both sides are placed horizontally and distributed in the circumferential direction. Since the rotor 151 of the generator having such a structure can be installed horizontally as described above, it can be magnetically levitated by the permanent magnets 154 and 155. However, when the permanent magnets 154 and 155 are handled, the permanent magnets 154 and 155 can be detached even if they are adhered to an adjacent magnetic metal. Alternatively, after attaching the permanent magnets 154, 155 to a predetermined position via a non-magnetic material such as an aluminum material, it is necessary to remove the aluminum material. In order to mount the permanent magnets 154 and 155, an aluminum material is required, and a space that cannot be effectively used for the mounting is required.
- FIG. 39 shows the state of the magnetic flux distribution of the fluid of both magnets A and B when the high-performance magnets A and B are brought close to each other. Since the magnetic flux generated from the N pole (the leakage magnetic flux at the end in the figure) comes close to each other (as the magnetic flux does not interlink! / ⁇ ), a repulsive force is generated. Therefore, it is difficult to hold both magnets A and B close to each other.
- Fig. 40 shows the repulsive force of high-performance magnets A and B placed in the air (when magnet A is fixed).
- the magnets A and B are 5 mm thick, 20 mm long and 10 mm wide, and the magnet B is attracted to the end face of the magnet A, the repulsive force acting on the magnet B is shown. Is about 30N, and it is very difficult to keep it for a long time with human hands.
- the workability of incorporating a high-performance magnet is poor because the magnet has high performance, and the magnetic flux leaks into the air, and the attractive force is generated between the magnet and the adjacent magnetic body. Is to occur.
- the magnetic flux generates an attractive force between it and the magnetic material, or the repulsive force between the magnets for floating is also the purpose of using a high-performance magnet.
- the measures for the attraction generated by the magnetic flux are necessary for the function and are not a problem.
- the magnetic flux passing through the side surface of the magnet in a direction other than the predetermined direction is a leakage magnetic flux, and this leakage magnetic flux generates unnecessary attractive force with a nearby magnetic body, or is unnecessary between the magnet and the magnet oriented in the same direction. If it is possible to prevent the occurrence of a repulsive force, workability can be improved.
- FIG. 41 is a diagram showing the magnetic flux distribution at the end when the magnetic material 158 is attached to the side surface of the magnet A.
- the magnetic flux at the end penetrates into the magnetic material 158, generating an attractive force.
- FIG. 42 shows an attractive force when the magnetic material 158 is sandwiched between the high-performance magnet A and the magnet B placed in the air.
- both magnets A and B have a thickness of 5 mm, a length of 20 mm, and a width of 10 m.
- the thickness of the magnetic body 158 is 5 mm, the length is lmm, and the width is 10 mm.
- the attractive force received by the magnet B on the side of the magnetic body 158 is about 30 N. To separate them requires great power. Therefore, it is difficult to separate magnets A and B.
- the height of the magnetic body 160 is made shorter than the thickness of the magnet so that a part of the magnetic flux leaks outside the magnetic body 160 on the side surface of the magnet.
- the magnetic body 160 which is partially cut away, is sandwiched between the high performance magnets A and B on the side.
- the leakage magnetic flux of the high-performance magnets A and B is a partial force that lacks the height of the magnetic body 160.
- the leaked magnetic flux repels each other and generates a repulsive force.
- the high performance magnets A and B are attracting each other. Therefore, the height and thickness of the magnetic body 160 can be appropriately set so that the repulsive force and the attractive force are balanced according to the magnets A and B by the magnetic field analysis, so that the problem can be solved.
- the resilient force and the attractive force of the adjacent magnets A and B are balanced by devising that the magnetic material 160 shorter than the thickness of the high-performance magnets A and B is attached to the side surfaces of the magnets A and B. This causes the action to be performed. Also, the length of the magnetic body 160 is such that magnets smaller than the length of the magnets A and B are densely arranged. Further, the magnetic body 160 is retracted inward from the surfaces of the magnets A and B, and has the effect that the magnetic flux force from the floating magnet 154 and the fixed-side magnet 155 does not concentrate on this portion. There is no adverse effect on ascent. FIG.
- Fig. 44 shows a specific embodiment, in which a magnetic body 160 shorter than the thickness of the magnets A and B is attached to the side surfaces of the magnets A and B as shown. At this time, the length of the magnetic body 160 is about lmm, which is shorter than the length of the magnets A and B of 20 mm. Therefore, it is close to a state where many magnets are closely arranged.
- Fig. 44 shows the calculation results of performing a magnetic field analysis with this arrangement of magnets.
- the magnetic material 160 having a thickness shorter than the thickness of the high-performance magnets A and B (permanent magnets 154 and 155) is attached to the side surfaces of the magnets A and B, and the adjacent magnets A Since the repulsive and attractive forces of B and B have been reduced, the mounting work of magnets A and B (permanent magnets 154 and 155) becomes easier, and the time required for assembly work on site can be reduced. Also, since the attractive force between the magnets A and B has been reduced, the overhaul work of the generator is easy. Furthermore, as a countermeasure against the repulsive force between the magnets A and B, various effects can be obtained in that a structure for fixing the magnets A and B is not required.
- a magnetic body 160 having a configuration as shown in FIG. 44 is interposed between a number of moving permanent magnets 154 shown in FIG. 38.

It should be noted that the bearing portion 165 may be replaced with a magnetic levitation structure using the above-described permanent magnet.

- the magnetic flux density distribution of outer stator 170a is trapezoidal, and the magnetic flux density distribution of inner stator 170b is triangular. Therefore, it is expected that the peak value and the waveform of the voltage induced in the coils of the outer stator 170a and the inner stator 170b are different, and the peak value and the waveform of the voltage of the outer stator 170a and the inner stator 170b are different.

- r2 is the outer diameter of the inner stator 170b.
- the conventional general power generator has a stator arranged on the outer diameter side of the rotor, so that the stator coil and the magnetic poles of the rotor are geometrically periodic in the circumferential direction. If they are arranged in a symmetrical manner, the U-phase, V-phase, and W-phase generated voltages are in the same circumferential direction on one side, so that a phase difference is unlikely to occur.
- the problem to be solved is to reduce the difference in generated voltage and the magnetic attractive force caused by the difference in magnetic flux density distribution on the stator coil side.
- the challenge is to find a solution on the stator coil side.
- the problem is caused by the difference in the magnetic flux density distribution between the stators on both sides, and the stator coil is wound in consideration of the difference in the distribution. Pressure may be generated. Since this generator has stator coils on both sides, when these in-phase stator coils are crossed, the voltage generated by the stator coils is the same in a normal state without eccentricity. At this time, even if the rotor 164 is eccentric, the degree of eccentricity can be further reduced if the generated voltage is the same as in the normal state. Such crossings should be made with stator coils.
- the magnetic flux density of the magnet is determined by the consumed ampere turn of the magnetic circuit of the magnet and the armature reaction of the stator.
- the ampere-turn consumed by the magnetic circuit is largely determined by the size of the gap between the stators 170a, 170b and the magnet 163, as shown in FIG.

Assuming that al is 10 and bl is 9, the size of each part of the magnet 163 is shown in FIG. At this time, the gap distances close to the normal state are d2 and f3, so it can be assumed that the magnetic flux density is 4 in the normal state. As shown in FIG. 50, it can be seen that the induced voltage differs depending on the phase. Considering the case where the rotor 164 is eccentric, the stator coils 172 on both sides cannot be simply crossed.
- the phase sequence in which the generated voltage of each phase is close to 8 that is, X--w---y--u--z--V, has no large generated voltage as a whole. Therefore, the current flowing through the stator coil 172 also decreases.

- FIG. 52 is a diagram showing a specific method of connecting the stator coil 172 to the outer stator 170a and the inner stator 17 Ob, in which the phase order is changed by 180 ° between the outer side and the inner side.
- the difference in the induced voltage due to the difference in the magnetic flux distribution between the two stators 170a and 170b is corrected by crossing the stator coils 172 on both sides of the magnetic pole pair of the rotor 164.
- the generation of a circulating current constantly flowing through the coil 172 is prevented, the generated voltages of the stators 170a and 170b on both sides are made the same, the load current can flow evenly, and the magnetic flux distribution at the time of load can be reduced by the stators 170a and 170a on both sides.
