  In the present embodiment, each of the first magnetic rotating device 1M1 and the second magnetic rotating device 1M2 is an electric motor. That is, the magnetic rotating device 1 is a double motor in which the rotating shaft 11 is connected so that the two motors rotate integrally. Therefore, the first magnetic rotating device 1M1 may be described as “motor 1M1”, and the second magnetic rotating device 1M2 may be described as “motor 1M2”.

  Further, when it is not necessary to distinguish between the electric motor 1M1 and the electric motor 1M2, the electric motor 1M may be referred to as either or both of them (that is, the entire magnetic rotating device 1).

  The frame 21 is provided with a nonmagnetic material such as stainless steel so as to mechanically maintain the electric motor 1M, and forms the outer shape of the electric motor 1M.

  The rotating shaft 11 is rotatably supported by the frame 21 by a bearing provided on the frame 21.

  The electric motor 1M1 is composed of two parts, an A electric motor M1A and a B electric motor M1B. The electric motor 1M2 is composed of two parts, an A electric motor M2A and a B electric motor M2B.

  In this embodiment, the structure of the components of the electric motor 1M1 and the electric motor 1M2 is the same. For example, the structures of the stators 12 and 16 themselves including the iron core 31 and the windings 32 and the structures of the rotors 13 and 17 including the permanent magnet 41 are the same in the electric motor 1M1 and the electric motor 1M2. However, the stator 12 of the electric motor 1M1 and the stator 16 of the electric motor 1M2 have different arrangement angles (phase angles) in the circumferential direction (rotation direction). Details are described below.

  That is, each of the motors 1M1 and 1M2 includes a plurality of stators 12, 16 in which N (N is an integer of 2 or more) iron cores 31 each having a winding 32 are arranged at equal intervals along the circumferential direction.

  In the electric motor 1M1 and the electric motor 1M2, the respective rotors 13 and 17 have a rectangular shape when viewed from the axial direction, and are formed with N poles and S poles formed along the tangential direction of the rotation circumference. (N / 2), in this embodiment, four permanent magnet bodies 41.

This will be described in more detail below.
[Description of the structure of the magnetic rotating device 1]
[Electric motor 1M1]
The electric motor 1M1 has a rotating shaft 11, a stator 12, a rotor 13, a frame 21, and the like.
〔stator〕
The stator 12 has a plurality of iron cores 31 having windings (coils) 32 arranged at equal intervals along the circumferential direction.

  Each iron core 31 is formed by laminating a U-shaped or U-shaped silicon steel sheet to a predetermined thickness, and has a body 311 at the center and legs 312a and 3b at both ends. . The ends of the legs 312a and 312b are rectangular end surfaces 313a and 313b, respectively, and the two end surfaces 313a and 313b are on the same plane and face the center of the rotating shaft 11 (FIG. 3).

  The windings 32 include two windings 32 a, b provided on each leg 312 a, b of the iron core 31, respectively. When a current flows through the windings 32a and 32b, a magnetic flux and a magnetic field are generated in the iron core 31, and the core 31 becomes an electromagnet. The two windings 32a, b are connected in parallel, for example, and a current is caused to flow in the iron core 31 so that a magnetic flux in the same direction is generated, so that different magnetic poles are formed on the end faces 313a, b. That is, one of the end faces 313a and 313b is an N pole, and the other is an S pole.

  In the present embodiment, the eight iron cores 31 are positioned so that the trunk 311 extends in parallel with the axial direction, that is, the two legs 312a and 312b are separated from each other along the axial direction. They are arranged at equal intervals above, that is, so that the central angle between the adjacent iron cores 31 is 45 degrees (= 360 degrees / 8) (see FIGS. 2 and 4).

  That is, the center lines LK passing through the centers of the cores 31 and passing through the center of the stator 12, that is, the rotation center KC of the rotor 13 (the axis of the rotation shaft 11), form a central angle of β1 = 45 degrees with each other. It has become. The distance between the end faces of the adjacent iron cores 31 is almost the same as or slightly smaller than the width of the end faces.

The center line LK of the iron core 31 (YA1) at the uppermost position is a vertical line, and this vertical line is considered as a reference line (= 0 degree) at the rotation angle positions of the stators 12, 16 and the rotors 13, 17. There is.
(Rotor)
The rotor 13 includes an A rotor 13a facing one leg 312a of the iron core 31 and a B rotor 13b facing the other leg 312b of the iron core 31 (see FIGS. 1 and 3). The A rotor 13a and the B rotor 13b rotate integrally and have the same basic structure, so that the A rotor 13a will be described in detail.

The A motor M1A described above is constituted by the side of the leg 312a of the stator 12 and the A rotor 13a, and the B motor described above is constituted by the side of the leg 312b of the stator 12 and the B rotor 13b. The electric motor M1B is configured.
[A rotor]
First, the A rotor 13a has a plurality of permanent magnet bodies 41 arranged at equal intervals along the circumferential direction, and is opposed to the stator 12, that is, by the plurality of end faces 313a of the stator 12. It rotates together with the rotating shaft 11 while facing the formed circumferential surface (see FIG. 2).

  In the present embodiment, the four permanent magnet bodies 41 are arranged at equal intervals on the circumference, that is, so that the central angle β3 between the adjacent permanent magnet bodies 41 is 90 degrees (= 360 degrees ÷ 4). Have been.

  As shown in FIG. 10, the permanent magnet body 41 is configured by stacking six permanent magnets (neodymium magnets) 41 a to 41 f containing neodymium (or neodymium) as a component in the direction of the magnetic pole, and has a rectangular parallelepiped shape as a whole. That is, it is formed in a block shape. Each of the permanent magnets 41a to 41f is plated with nickel so that the surface becomes smooth. However, various configurations can be adopted as the configuration of the permanent magnet body 41. For example, the permanent magnet body 41 may be configured by one permanent magnet, or a connecting iron core made of a magnetic material may be inserted between two permanent magnets.

  Referring to FIG. 4, two opposing surfaces of the rectangular parallelepiped are magnetic pole surfaces 411a and 411b, and one of magnetic pole surfaces 411a and 411b is an N pole and the other is an S pole. That is, the magnetic pole surface 411a on the front side in the rotation direction of the arrow DS (that is, the left rotation direction in the drawing) is the N pole, and the magnetic pole surface 411b on the rear side is the S pole.

  The permanent magnet 41 is symmetrical with respect to a line (center line) LT passing through the center thereof. The center line LT is a line passing through the rotation center KC of the rotor 13. That is, the permanent magnet body 41 is disposed such that the direction connecting the two magnetic pole surfaces 411a and 411b coincides with the tangential direction of the rotation circumference.

  FIG. 4 illustrates a line (magnetic pole line) LU passing through the vertex TP, which is two corners outside the permanent magnet body 41, and passing through the rotation center KC. In the figure, the magnetic pole line LU coincides with the center line LK. The central angle β2 of the two vertices TP, that is, the central angle β2 of the two magnetic pole lines LU is β2 = (360 / N) degrees. In the present embodiment, since N = 8, β2 = 45 degrees.

  That is, the center angle β2 of the two vertices TP and the center angle β1 of the center line LK of the two iron cores 31 are equal to each other and are 45 degrees. Therefore, when the vertex TP on the N pole side of the permanent magnet body 41 is at the position of the center line LK of the iron core 31, the vertex TP on the S pole side is at the position of the center line LK of the adjacent iron core 31.

  Note that a side plate member 45 and the like are provided to support the permanent magnet body 41 and to connect the permanent magnet body 41 so as to rotate integrally with the rotating shaft 11. The side plate member 45 is a disk-shaped member provided with a concave portion so as to sandwich and position each of the permanent magnet bodies 41 from both sides in the axial direction. The side plate member 45 is made of a nonmagnetic material and an insulating material such as synthetic resin. The side plate member 45 is fixed to a cylindrical bush 47 through which the rotating shaft 11 passes. The bush 47 is rotated integrally with the rotation shaft 11 by a key 48.

The material and shape of the side plate members 45 and the like can be various other than those described above.
[B rotor]
Next, the B rotor 13b will be described.

  The B rotor 13b has basically the same structure as that of the A rotor 13a described above, but the polarities of the permanent magnets 41 are different from each other.

  That is, the B rotor 13b, that is, the portion of the rotor 13 facing the leg 312b of the iron core 31 has a plurality of permanent magnets 41 arranged at equal intervals along the circumferential direction, similarly to the A rotor 13a. The rotor rotates together with the rotating shaft 11 in a state facing the stator 12, that is, in a state facing a circumferential surface formed by the plurality of end faces 313b of the stator 12.

  In addition, the A rotor 13a and the B rotor 13b are arranged such that the arrangement of the permanent magnet bodies 41 coincides with each other and overlaps on a straight line when viewed from the front direction and the direction along the suspension rotation axis 11. Therefore, the respective center lines LT also coincide with each other and overlap.

Regarding the polarity of the permanent magnet body 41, as shown in FIG. 2, in the A rotor 13a, the magnetic pole surface 411a on the front side in the rotation direction of the arrow DS is the N pole, and the magnetic pole surface 411b on the rear side is the S pole. In the B rotor 13b, the magnetic pole surface 411a on the front side of the arrow DS is the S pole, and the magnetic pole surface 411b on the rear side is the N pole. That is, in the B rotator 13b, the polarity is such that “N” and “S” in FIG. 2 are interchanged.
[Electric motor 1M2]
Next, the electric motor 1M2 will be described.

  As described above, the structure of the components of the stator 16 and the rotor 17 of the electric motor 1M2 is the same as that of the electric motor 1M1. The difference is that the phase angle at which the stator 16 of the electric motor 1M2 is arranged is shifted from the stator 12 of the electric motor 1M1 in the direction of the arrow DS by an arrangement phase angle β4 = 22.5 degrees. Further, as shown in FIG. 1, the rotor 17 includes an A rotor 17a and a B rotor 17b.

  That is, in FIGS. 2 and 4, the eight iron cores 31 of the stator 12 of the electric motor 1M1 are indicated by solid lines, and the eight iron cores 31 of the stator 16 of the electric motor 1M2 are indicated by two-dot chain lines. As can be seen from the figure, the arrangement angles of the eight iron cores 31 (shown by two-dot chain lines) of the stator 16 of the electric motor 1M2 are the same as those of the eight iron cores 31 (shown by solid lines) of the stator 12 of the electric motor 1M1. The arrangement angle is shifted from the arrangement angle by an arrangement phase angle β4 = 22.5 degrees in the rotation direction of the arrow DS.

  Specifically, with respect to the center line LK of the iron core 31 (YA1) at the highest position of the electric motor 1M1 in FIG. 4, that is, with respect to the vertical line, the center line LK of the iron core 31 (YC1) at the highest position of the electric motor 1M2 is The arrangement phase angle β4 is shifted by 22.5 degrees in the rotation direction of the arrow DS.

  On the other hand, the arrangement of the rotor 13 of the electric motor 1M1 and the rotor 17 of the electric motor 1M2 along the circumferential direction of the permanent magnet 41 match each other. That is, the permanent magnet bodies 41 are arranged at the same phase angle, and the arrangement phase angle β5 is 0 degree.

  That is, in the state shown in FIG. 2 and FIG. 4, the phase angle γ1 between the stator 12 and the rotor 13 in the electric motor 1M1 is changed by the center line LK of the iron core 31 (YA1) at the uppermost position and the center line of the permanent magnet body 41. Assuming that the angle formed with LT is an angle measured in the direction of arrow DS, phase angle γ1 is 22.5 degrees. The phase angle γ2 between the stator 16 and the rotor 17 in the electric motor 1M2 is defined by the distance between the center line LK of the iron core 31 (YC1) and the center line LT of the permanent magnet body 41 arranged forward of the arrow DS from the uppermost position. If the angle formed is an angle measured in the direction of arrow DS, phase angle γ2 is 0 degree. Therefore, the dislocation angle δ (= γ1−γ2), which is the difference between the phase angle γ1 and the phase angle γ2, is δ = 22.5-0 = 22.5 degrees.

  Since the rotors 13 and 17 rotate integrally, the relationship (the difference value) between the phase angle γ1 and the phase angle γ2 is the same regardless of the angular position of the rotors 13 and 17; The displacement angle δ is always constant at 22.5 degrees. That is, since the arrangement phase angle β5 for the permanent magnet body 41 is 0 degrees, the arrangement phase angle β4 for the iron core 31 becomes the arrangement deviation angle δ as it is.

  That is, in order to set the displacement angle δ to (180 / N) degrees, that is, 22.5 degrees, in the electric motors 1M1 and 1M2, the angular positions where the stators 12, 16 and the rotors 13, 17 are arranged. May be in a predetermined relationship.

  For example, in the electric motor 1M1 and the electric motor 1M2, the arrangement phase angle β4 of the iron core 31, ie, the arrangement phase angle β4 of the stators 12, 16, and the arrangement phase angle β5 of the permanent magnet 41, ie, the arrangement phase angle β5 of the rotors 13, 17 Β4 + β5, which is the sum of the above, should be 22.5 degrees.

  In the magnetic rotating device 1 of the present embodiment, the arrangement phase angle β4 of the stators 12 and 16 is 22.5 degrees, and the arrangement phase angle β5 of the rotors 13 and 17 is 0 degrees.

  However, for example, the arrangement phase angle β4 of the stators 12 and 16 may be set to 15 degrees, and the arrangement phase angle β5 of the rotors 13 and 17 may be set to 7.5 degrees. Further, the arrangement phase angle β4 of the stators 12 and 16 may be set to 0 degree, and the arrangement phase angle β5 of the rotors 13 and 17 may be set to 22.5 degrees.

That is, when the permanent magnet body 41 of the electric motor 1M2 is shifted in the direction opposite to the arrow DS with respect to the permanent magnet body 41 of the electric motor 1M1 and the arrangement phase angle β5 is set to 22.5 degrees, the iron core 31 of the electric motor 1M1 is By setting the arrangement phase angle β4 of the electric motor 1M2 with respect to the iron core 31 to 0 degree, the arrangement deviation angle δ becomes 22.5 degrees.
[Description of the polarity of the permanent magnet]
FIG. 5 shows the arrangement of the iron core 13 and the permanent magnet 41 in the first magnetic rotating device (motor 1M1) of the magnetic rotating device 1 of the first embodiment, and FIG. 6 shows the second magnetic rotating device. FIG. 7 shows a diagram for explaining the rotating magnetic field in the magnetic rotating device 1 for the arrangement relationship between the iron core 16 and the permanent magnet body 41 in the (motor 1M2).

  5 and 6 correspond to cross-sectional arrows at positions AA-AA and CC-CC in FIG. 1, and FIG. 7 shows FIGS. 5 and 6 in an overlapping manner. is there.

  In FIGS. 2 and 4 to 7, the rotors 13 and 17 can rotate in a free state where no current flows through the winding 32 and no external rotational force is applied to the rotating shaft 11. One state of the angular position is shown.

  As described above, in FIG. 5, the center lines LK of the iron cores 31 form central angles of β1 (= 45 degrees) with each other. The center lines LT of the permanent magnet bodies 41 form central angles of β3 (= 90 degrees) with each other. In the state of FIG. 5, the phase angle γ1 between the stator 12 and the rotor 13 is 22.5 degrees.

  In FIG. 6, the center lines LK of the iron core 31 form a center angle of β1 (= 45 degrees) with each other. The center lines LT of the permanent magnet bodies 41 form central angles of β3 (= 90 degrees) with each other. In the state shown in FIG. 6, the phase angle γ2 between the stator 16 and the rotor 17 is 0 degree.

  In FIG. 5, the core 31 at the uppermost position is "YA1", and every other one is "YA2", "YA3", and "YA4" along the direction of the arrow DS. The first iron core 31 in the direction of the arrow DS of the core 31 of “YA1” is “YB1”, and every other iron core along the direction of the arrow DS is “YB2”, “YB3”, and “YB4”.

  In FIG. 6, the iron core 31 disposed forward of the arrow DS from the uppermost position is “YC1”, and “YC2”, “YC3”, and “YC4” are alternately arranged along the direction of the arrow DS. The first core 31 in the direction of arrow DS of the core 31 of “YC1” is “YD1”, and “YD2”, “YD3”, and “YD4” are alternately arranged along the direction of arrow DS.

  In FIG. 7, assuming that four iron cores 31 adjacent to each other in the direction of arrow DS from the core 31 of “YA1” at the uppermost position are a set of iron cores, the cores are partitioned into four sets of cores 1 to 4. You. Further, for each group of iron core groups, the four iron cores 31 are A-phase, C-phase, B-phase, and D-phase in the direction of arrow DS.

  That is, the eight windings 32 of the iron core 31 of the electric motor 1M1 are alternately divided into four A phases and four B phases along the circumferential direction of the arrow DS. The eight windings 32 of the electric motor 1M2 iron core 31 are alternately divided into four C phases and four D phases along the circumferential direction of the arrow DS.

  A current is applied to the windings 32 in the order of A-phase, C-phase, B-phase, and D-phase simultaneously to excite the four sets of iron cores to excite them, thereby generating a rotating magnetic field in the direction of arrow DS. That is, a rotating magnetic field that moves in the order of A phase, C phase, B phase, and D phase is formed. Due to this rotating magnetic field, the permanent magnet bodies 41 of the rotors 13 and 17 are attracted or repelled and driven to rotate synchronously in the same direction as the rotating magnetic field. The rotors 13 and 17 make one quarter rotation in one cycle of the A phase, C phase, B phase and D phase, and make one rotation in four cycles.

  Attraction between the permanent magnet body 41 and the iron core 31 by the magnetic force of the permanent magnet body 41 acts, thereby generating a detent torque (cogging torque). The pattern including the magnitude and direction of the detent torque is repeated for each of the central angles β1 (= 45 degrees) of two adjacent iron cores 31 in each of the electric motors 1M1 and 1M2. However, the misalignment angle δ between the electric motors 1M1 and 1M2 is 22.5 degrees, whereby the detent torque generated in the electric motor 1M1 and the detent torque generated in the electric motor 1M2 cancel each other, and the overall detent torque is greatly increased. It will be reduced to.

  That is, the rotor 13 of the electric motor 1M1 and the rotor 17 of the electric motor 1M1 have phases opposite to each other with respect to the change of the detent torque by the permanent magnet 41, and the respective detent torques cancel each other out. The combined detent torque goes to zero or is greatly reduced.

  By reducing the detent torque, the efficiency of the magnetic rotating device 1 is improved. For example, when a test was performed using the magnetic rotating device 1 in which the rotors 13 and 17 had a diameter of 100 mm, the output torque when the electric motor 1M1 or the electric motor 1M2 was used alone was shown in FIG. The output torque when used as the magnetic rotating device 1 was increased not to be doubled but to approximately 2.5 to 2.6 times.

  As described above, in the magnetic rotating device 1 of the first embodiment, the rotating magnetic field by the four phases of the A phase, the C phase, the B phase, and the D phase, the A phase and the B phase for the electric motor 1M1, and the rotating magnetic field for the electric motor 1M2. The C-phase and the D-phase are respectively assigned, and the rotors 13 and 17 connected integrally are rotationally driven. Then, by canceling the detent torque of the rotor 13 in the electric motor 1M1 and the detent torque of the rotor 16 in the electric motor 1M2, the entire detent torque is greatly reduced.

  In the above-described embodiment, both the first magnetic rotating device 1M1 and the second magnetic rotating device 1M2 constituting the magnetic rotating device 1 are the electric motors 1M1 and 1M2, and thereby, one electric motor 1M did. However, one of the first magnetic rotating device 1M1 and the second magnetic rotating device 1M2 may be configured as a generator, and the magnetic rotating device 1 may be configured as a motor generator, or both may be configured as a generator. . In either case, the detent torque is greatly reduced and efficiency is improved.

Further, the third and fourth magnetic rotating devices 1M3 and 1M4 may be further connected to form one magnetic rotating device 1.
[Second embodiment]
FIG. 8 shows an arrangement relationship between the iron core and the permanent magnet of the second magnetic rotating device 1BM2 in the magnetic rotating device 1B of the second embodiment.

  That is, the magnetic rotating device 1B according to the second embodiment differs from the magnetic rotating device 1 according to the first embodiment in that a second magnetic rotating device 1M2 shown in FIG. 6 is replaced by a second magnetic rotating device shown in FIG. This is replaced with the device 1BM2.

  In the second embodiment, the second magnetic rotating device 1BM2 is a generator, and the second magnetic rotating device 1BM2 may be referred to as “generator 1BM2”. That is, the magnetic rotating device 1B is configured as a motor generator that connects the motor 1M1 and the generator 1BM2.

  In the generator 1BM2, similarly to the electric motor 1M2 of the first embodiment, N (N is an integer of 2 or more, N = 8 in the present embodiment) cores 31 having windings 32 are provided in the circumferential direction. , And a rotor 17B having a plurality of permanent magnet bodies 51 arranged at equal intervals along the circumferential direction and having N magnetic poles. In the present embodiment, the center lines LK of the eight iron cores 31 form a central angle of β1 (= 45 degrees) with each other.

  In the generator 1BM2, the phase angles of the stator 16B are arranged in the same state without being shifted with respect to the stator 12 of the electric motor 1M1 shown in FIG. That is, the center line LK of the stator 12 matches the center line LK of the stator 16B, and the arrangement phase angle β4 for the stators 12 and 16B is 0 degree.

  That is, the center line LK of the core 31 of “YC1” at the highest position of the generator 1BM2 shown in FIG. 8 is a vertical line, and the center line LK of the core 31 (YA1) at the highest position of the motor 1M1 in FIG. Matches.

  Further, in the generator 1BM2, the rotor 17B has a rectangular shape when viewed from the axial direction and has N magnetic poles and S magnetic poles formed along the radial direction and arranged in the radial direction. It has eight permanent magnet bodies 51.

  Here, with respect to the eight permanent magnet bodies 51, two adjacent permanent magnet bodies 51, 51 constitute one set. That is, in FIG. 8, each of the two permanent magnet bodies 51, 51 shown at the upper, left, right, and lower positions of the rotor 17B is a set. Then, the center line LTg located at the center of each set of permanent magnet bodies 51 becomes a vertical line or a horizontal line in the state shown in FIG. 8 and coincides with the center line LK of the iron core 31, respectively. Then, two adjacent center lines LTg form a center angle of β3 (= 90 degrees) with each other.

  In generator 1BM2, four center lines (radial lines) LTg are used to indicate the phase angle of rotor 17B.

  As described above, in the magnetic rotating device 1B of the second embodiment, the electric motor 1M1 (see FIG. 5), which is the first magnetic rotating device in the magnetic rotating device 1 of the first embodiment, and the second rotating device shown in FIG. The generator 1BM2, which is a magnetic rotating device, is connected in an angular positional relationship shown in FIGS. 5 and 8, and the rotors 13 and 17B rotate integrally while maintaining this angular positional relationship.

  Therefore, in the magnetic rotating device 1B, the phase angle γ1 between the stator 12 and the rotor 13 in the electric motor 1M1 is 22.5 degrees, and the phase angle γ2 between the stator 16B and the rotor 17B in the generator 1BM2 is 0 degrees. It is.

  Accordingly, in the magnetic rotating device 1B, the phase angle γ1 between the stator 12 and the rotor 13 of the electric motor 1M1 in the state shown in FIG. 5 and the stator 16B and the rotor 17B of the generator 1BM2 in the state shown in FIG. The stators 12, 16B and 12B are arranged so that the misalignment angle δ (= γ1−γ2), which is the difference from the phase angle γ2, becomes δ = (180 / N) degrees, and in the present embodiment, 22.5 degrees. The rotors 13 and 17B are arranged.

  In other words, the arrangement phase angle β4 of the stators 12 and 16B is 0 degree, and the arrangement phase angle β5 of the rotors 13 and 17B is 22.5 degrees.

  Although FIG. 8 shows only the A rotor (17Ba) in the generator 1BM2, the generator 1BM2 has the B rotor (17Bb) as described for the electric motor 1M2 shown in FIG. I have. The B rotor (17Bb) of the generator 1BM2 is basically the same in structure as the A rotor (17Ba) shown in FIG. 8, except that the polarity of the permanent magnet body 51 is different from that of the A rotor (17Ba). Is only the opposite.

  In the present embodiment, N = 8, which means an eight-pole magnetic rotating device 1B. In the 8-pole magnetic rotating device 1B, since the misalignment angle δ is 22.5 degrees, that is, (180 / N) degrees, the detent torque generated in the electric motor 1M1 and the detent torque generated in the generator 1BM2 are mutually Thus, the total detent torque is greatly reduced. As a result, a highly efficient magnetic rotating device 1B is obtained.

  In the magnetic rotating device 1B of the second embodiment, the electric motor 1M1 generates a rotating magnetic field of two phases A and B, thereby driving the rotor 13 to rotate, and the generator connected by the rotating shaft 11. The rotor 17B of 1BM2 is rotationally driven. Two-phase AC power is extracted from the winding 32 of the generator 1BM2.

Note that the permanent magnet body 51 may be configured by stacking a plurality of permanent magnets in the magnetic pole direction in the same manner as in the case of the permanent magnet body 41.
[Third embodiment]
FIG. 9 shows an arrangement relationship between the iron core and the permanent magnet of the first magnetic rotating device 1CM1 in the magnetic rotating device 1C of the third embodiment.

  That is, the magnetic rotating device 1C according to the third embodiment differs from the magnetic rotating device 1 according to the first embodiment in that the electric motor 1M1 shown in FIG. 5, which is the first magnetic rotating device, is replaced by the first magnetic rotating device shown in FIG. This is replaced with the device 1CM1.

  In the third embodiment, the first magnetic rotating device 1CM1 is a generator, and the first magnetic rotating device 1CM1 may be referred to as “generator 1CM1”. That is, the magnetic rotating device 1C is configured as a motor generator that connects the generator 1CM1 and the motor 1M2.

  The generator 1CM1 includes N winding cores 31 (N is an integer of 2 or more, N = 8 in the present embodiment) provided with windings 32 in the same manner as in the first embodiment along the circumferential direction. It has a stator 12C arranged at intervals and a rotor 13C having N magnetic poles in which a plurality of permanent magnet bodies 52 are arranged at equal intervals along the circumferential direction. In the present embodiment, the center lines LK of the eight iron cores 31 form a central angle of β1 (= 45 degrees) with each other.

  In generator 1CM1, central angle β1 of center line LK of each iron core 31, central angle β2 of two magnetic pole lines LU in adjacent permanent magnet bodies 52, 52, and center of adjacent permanent magnet bodies 52, 52 are located. The center angle β3 between the center lines LTg and the phase angle γ1 between the stator 12C and the rotor 13C in the state shown in FIG. 9 are the same as in the case of the electric motor 1M1 shown in FIG.

  That is, in the generator 1CM1, the phase angle of the stator 12C is arranged without being shifted with respect to the stator 16 of the electric motor 1M2 shown in FIG. The angle β4 is 0 degree.

  In the generator 1CM1, the rotor 13C has eight permanent magnets 52 similar to the permanent magnets 51 described above. The eight permanent magnet bodies 52 are located at the center of each set of four permanent magnet bodies 52 adjacent to each other in the counterclockwise direction from the uppermost permanent magnet body 52 shown in FIG. The center lines LTg form a center angle of β3 (= 90 degrees) with each other.

  As described above, in the magnetic rotating device 1C of the third embodiment, the generator 1CM1, which is the first magnetic rotating device shown in FIG. 9, and the second magnetic rotating device 1 of the first embodiment shown in FIG. And the electric motor 1M2 (see FIG. 6), which is a magnetic rotating device, is connected in an angular positional relationship shown in FIGS. 9 and 6, and the rotors 13C and 17 rotate integrally while maintaining this angular positional relationship. I do.

  Therefore, in the magnetic rotating device 1C, the phase angle γ1 between the stator 12C and the rotor 13C in the generator 1CM1 is 22.5 degrees, and the phase angle γ2 between the stator 16 and the rotor 17 in the electric motor 1M2 is 0 degrees. It is.

  Therefore, in the magnetic rotating device 1C, the phase angle γ1 between the stator 12C and the rotor 13C of the generator 1CM1 in the state shown in FIG. 9 and the stator 16 and the rotor 17 of the electric motor 1M2 in the state shown in FIG. The stators 12C, 16 and 16 are arranged such that the misalignment angle δ (= γ1−γ2), which is the difference from the phase angle γ2, becomes δ = (180 / N) degrees, and in this embodiment, 22.5 degrees. The rotors 13C and 17 are arranged.

  In other words, the arrangement phase angle β4 of the stators 12C and 16 is 0 degree, and the arrangement phase angle β5 of the rotors 13C and 17 is 22.5 degrees.

  Note that FIG. 9 shows only the A rotor (13Ca) in the generator 1CM1, but has the B rotor as described for the electric motor 1M1 shown in FIG. That is, the B rotor of the generator 1CM1 is basically the same in structure as the A rotor (13Ca) shown in FIG. 9, and differs only in that the polarity of the permanent magnet body 52 is opposite to that of the A rotor. .

  In the present embodiment, N = 8, which means that the magnetic rotating device 1C has eight poles. In the 8-pole magnetic rotating device 1C, the misalignment angle δ is 22.5 degrees, that is, (180 / N) degrees, so that the detent torque generated in the generator 1CM1 and the detent torque generated in the electric motor 1M2 are mutually different. Thus, the total detent torque is greatly reduced. Thereby, the efficiency of the magnetic rotating device 1C is improved.

In the magnetic rotating device 1C of the second embodiment, the electric motor 1M2 generates a rotating magnetic field of two phases, C phase and D phase, thereby driving the rotor 16 to rotate, and the generator connected by the rotating shaft 11 The rotor 13C of 1CM1 is rotationally driven. Two-phase AC power is extracted from the winding 32 of the generator 1CM1.
[Fourth embodiment]
Although the magnetic rotating device 1D of the fourth embodiment is not particularly shown in the drawing, the first magnetic rotating device 1CM1 shown in FIG. 9 and the second magnetic rotating device 1BM2 shown in FIG. The rotors 13C and 17B rotate integrally while maintaining this angular positional relationship.

  The first magnetic rotating device 1CM1 and the second magnetic rotating device 1BM2 are both generators. That is, the magnetic rotating device 1D is a double generator in which the rotating shafts 11 are connected so that the two generators rotate integrally. The magnetic rotating device 1D is rotationally driven by another appropriate rotational driving device such as the electric motor 1M of the first embodiment.

  From the windings 32 of the generators 1CM1 and 1BM2, two-phase two sets of AC power are extracted.

  Also in the magnetic rotating device 1D, the detent torques generated in the first magnetic rotating device 1CM1 and the second magnetic rotating device 1BM2 cancel each other, and the entire detent torque is greatly reduced, so that the efficiency of the magnetic rotating device 1D is reduced. improves.

Further, the first magnetic rotating device 1CM1 or the second magnetic rotating device 1BM2 can be used as an electric motor.
[Regarding control, etc.]
[Control in double motor]
Next, control of the magnetic rotating device 1 will be described.

  1 and 11, photointerrupters 61a to 61d are provided to detect the rotation angle position of the rotation shaft 11. A shielding disk 62 is attached to the rotating shaft 11 and rotates integrally, and the photo interrupters 61 a to 61 d are turned on and off according to the rotation angle position of the shielding disk 62.

  That is, the mounting plate 63 is fixed to the end face of the frame 21 by screws or the like using the mounting long holes 63a. Four photo interrupters 61a to 61d are attached to the attachment plate 63 by screws. As shown in FIG. 11, the photo interrupters 61a to 61d are attached at equal intervals of 22.5 degrees to each other in the order of the photo interrupters 61b, 61d, 61a, and 61c along the left rotation direction.

  The shielding disk 62 is provided with four slits 62S1 to 4 at regular intervals of 45 degrees, and when the slits 62S1 to 4 come to the positions of the photo interrupters 61a to 61d, the corresponding photo interrupters 61a to 61d. Turns on. On the basis of the on / off signals of the photo interrupters 61a to 61d, the rotation angle position of the rotation shaft 11, that is, the rotation angle positions of the rotors 13 and 17 are detected.

  In the shielding disk 62 shown in FIG. 11, the central angle θ1 of the opening of each of the slits 62S1 to 4 is 22 degrees, so that the photointerrupters 61a to 61d rotate the shielding disk 62 four times in one rotation. It turns on in the range of θ1 (= 22 degrees). The angle θ1 can be variously changed and set other than 22 degrees. For example, the angle can be set to 20 degrees, 21 degrees, 21.5 degrees, and other angles.

  By adjusting the rotation angle position at which the mounting plate 63 is mounted, the entire rotation angle position of the four photo interrupters 61a to 61d can be adjusted, thereby adjusting the timing at which the photo interrupters 61a to 61d are turned on. be able to. That is, the rotation angle position at which the photo interrupters 61a to 61d are turned on with respect to the rotors 13 and 17 can be adjusted. Scales 62M for confirming the angular positional relationship between the slits 62S1 to 4 and the photointerrupters 61a to 61d are provided on the peripheral edges of the slits 62S1 to 62S4.

  Note that the rotation angle positions of the photo interrupters 61a to 61d to which the mounting plate 63 is mounted may be individually adjusted.

  The rotation angle positions of the slits 62S1 to 4 of the shielding disk 62 shown in FIG. 11 correspond to the rotation angle positions of the rotors 13 and 17 shown in FIGS. 4 to 7 described above, and are connected in this state. And rotate together.

  In the state shown in FIG. 11, the photo interrupter 61a starts to be turned on by the slit 62S1 at the uppermost position, and is kept on while the shielding disk 62 rotates by the angle θ1 in the direction of the arrow DS. When the shielding disk 62 rotates 22.5 degrees in the direction of the arrow DS, the photo interrupter 61c starts to be turned on, and is kept on while the photo interrupter 61c is further rotated from the position by the angle θ1. Then, when the shielding disk 62 rotates 22.5 degrees in the direction of the arrow DS, the next slit 62S2 turns on the photointerrupters 61b and 61d sequentially, and is kept on within the range of the angle θ1.

  As described above, the rotation of the shielding disk 62 in the direction of the arrow DS turns on the photointerrupters 61a, 61c, 61b, and 61d in the order of the angle θ1 from the position of FIG.

  The timing at which the photointerrupters 61a to 61d are turned on can be adjusted by adjusting the rotational angle position where the shielding disk 62 is attached. For example, if the shielding disk 62 is rotated by the angle θ3 in the direction of the arrow DS so that the photointerrupter 61a is at the position indicated by the photointerrupter 61aT, the timing at which the photointerrupters 61a to 61d are turned on is only the angle θ3. Be late. The output torque of the electric motor 1M can be adjusted by delaying or increasing the timing at which the photo interrupters 61a to 61d are turned on. In the present embodiment, the range of the angle θ3 at which the torque can be adjusted is about 9 degrees.

  Further, by changing the rotation angle positions of the slits 62S1 to 62S4 of the shielding disk 62, the rotation driving direction of the electric motor 1M can be reversed. For example, when the shielding disk 62 is adjusted so that the right end of the uppermost slit 62S1 shown in FIG. 11 is located at the center of the photointerrupter 61a, the rotation directions of the rotors 13 and 17 are opposite to the arrow DS. .

  FIG. 12 shows an example of the configuration of the control device 71, and FIG. 13 shows how the control device 71 controls on / off of the current of the winding 32 of the electric motor 1M.

  12, the control device 71 includes a gate control unit 72 and a switching unit 73. The switching unit 73 includes an A-phase switching unit 73A, a C-phase switching unit 73C, a B-phase switching unit 73B, and a D-phase switching unit 73D.

  The gate control unit 72 generates timing signals S2A, S2C, S2B, and S2D for turning on and off the current flowing through each winding 32 of the electric motor 1M based on the signals S1a to S1d output from the photo interrupters 61a to 61d.

  That is, as shown in FIG. 13, when the apex TP of the S pole of the permanent magnet body 41 of the electric motor 1M (see FIG. 4) comes to the center of the iron cores YA, YC, YB, YD corresponding to each phase, or When a certain rotation angle is passed, the corresponding switching units 73A, 73C, 73B, 73D are controlled to be turned on. Then, after the respective switches are turned on, when the vertex TP is rotated by the on angle θ2, the corresponding switching units 73A, 73C, 73B, 73D are controlled to be turned off.

  The ON angle θ2 here varies depending on the shape, arrangement, size of the load, and the like of the permanent magnet body 41, and is adjusted to be the optimum ON angle θ2. In the present embodiment, the adjustment is performed so that θ2 = 22 degrees (mechanical angle).

  When the ON angle θ2 is 22 degrees, the ON timings of the switching units 73A, 73C, 73B, 73D do not overlap. The ON angle θ2 can be set to an appropriate angle other than 22 degrees. For example, the angle can be set to 20 degrees, 21 degrees, 21.5 degrees, and other angles.

  Further, the ON angle θ2 can be made to coincide with the angle θ1 at which the photo interrupters 61a to 61d are turned on. That is, the angle θ1 at which the photointerrupters 61a to 61d are turned on and the ON angle θ2 at which the switching units 73A, 73C, 73B, 73D are turned on may be matched. In this case, the gate control unit 72 may output the timing signals S2A, S2C, S2B, and S2D in accordance with the timing of the signals S1a to S1d of the photo interrupters 61a to 61d. For example, the signals S1a to S1d of the photo interrupters 61a to 61d may be directly output as timing signals S2A, S2C, S2B, and S2D.

  The windings 32 of the cores YA, YC, YB, YD of the corresponding phase are connected in parallel to the output terminals of the switching units 73A, 73C, 73B, 73D of each phase. When the switching unit 73 of each phase is turned on, a current flows through the winding 32, and the corresponding iron cores YA to YD are excited.

  For example, the iron core 31 facing the magnetic pole of the permanent magnet body 41 is magnetized by applying a current to the winding 32 so that the magnetic pole of the permanent magnet body 41 repels. The next magnetic pole of the permanent magnet body 41 is attracted by the magnetization of the iron core 31.

  As described above, a repulsive force or an attractive force is generated between the magnetic poles of the permanent magnet body 41, thereby generating a rotational torque, and the rotary shaft 11 is driven to rotate.

  The control device 71 is provided with terminals TB1 and TB2 for supplying power, and a DC power supply is connected to the terminals TB1 and TB2. As the DC power supply, for example, a stabilized DC power supply having a voltage of about 12 volts, 24 volts, 34 volts or more, or a battery can be used.

In the control example described above, the current is supplied to the winding 32 at the same time when the vertex TP reaches the center position of the iron core. However, these timings can be shifted back and forth.
[Control of motor in motor generator]
Next, control of the magnetic rotating devices 1B and 1C will be described.

  In this case, the electric motor 1M1 or 1M2 is controlled to be driven to rotate alone. Therefore, control is performed so that two-phase currents of A-phase and B-phase or C-phase and D-phase flow to the windings 32 of the electric motor 1M1 or 1M2. The ON angle θ2 may be larger than 22 degrees. Others are the same as the case of the control of the magnetic rotating device 1.

  In the magnetic force rotating devices 1B and 1C, since the detent torque is reduced, the rotation speed is not uneven, and the output waveforms of the generators 1BM2 and 1CM1 can be made a clean sine wave.

The control device 71 can variably adjust the cycle, frequency, magnitude, etc. of the currents IA, IB, IC, ID output to the electric motors 1M1 and 1M2, whereby the rotation speed and power (output ) Can be controlled.
