  Hereinafter, the present invention will be described in more detail with reference to specific examples, but the present invention is not limited to these examples.

  Embodiment 1 of the present invention will be described below with reference to FIGS. FIG. 1 is a schematic diagram for explaining a magnetic rotating device according to a first embodiment of the present invention.

  In FIG. 1, a rotation shaft 2 as a support shaft is supported by a bearing 3 at the center of a fixed frame 1. The rotating body 4 is fixed coaxially with the rotating shaft 2, and at least two magnetic poles 7A, 7B, 7C, 7D of the same polarity are opposed to the outer peripheral surface 5 and the circumferential surface 6 of the rotating body 4. A pair of magnetic field generating means 7 is arranged. That is, a plurality of rotor-side magnetic field generating means 7C, 7D, 7C, 7D, which are rotor magnetic poles in the embodiment in the radial direction around the rotating shaft 2, are integrally provided. On the other hand, outside the magnetic field generating means 7C, 7D, 7C, 7D, a plurality of radial directions are also formed around the rotary shaft 2, and in the embodiment, the stator side magnetic field generating means 7A, 7B, 7A, which are the stator magnetic poles in four directions. 7B is provided. The combination of the magnetic field generating means 7 disposed on the outer peripheral surface 5 and the circumferential surface 6 of the rotating body 4 in the present embodiment is a permanent magnet and an electromagnet, but may be a permanent magnet and a permanent magnet. Between the outer peripheral surface 5 and the circumferential surface 6 of the rotating body, a magnetic force for controlling a magnetic repulsive force generated by a pair of the magnetic field generating means 7 disposed on the outer peripheral surface 5 and the circumferential surface 6. At least one pair of the control bodies 8 are arranged close to each other. The magnetic force control body 8 is disposed so as to shield the entire surface of all the magnetic field generating means 7 disposed on the outer peripheral surface 5 and the circumferential surface 6 of the rotating body 4, and is fixed to the rotating shaft 2. Established. The magnetic force control body 8 may be fixed to the frame 1 without being fixed to the rotating shaft 2. In an embodiment, the magnetic force control body 8 has a cylindrical shape with the rotation shaft 2 as the rotation center, and the peripheral surface is the magnetic field generation means 7C, 7D, 7C, 7D and the magnetic field generation means 7A, 7B, 7A, 7B is provided so as to be interposed between the rotating shaft 2 and the center of both side portions thereof. The magnetic force control body 8 is controlled by a slip ring 9 serving as a control device. A slip ring 9 that makes electrical contact according to the rotational angle of the rotating body 4 and a slip ring 10 that always makes electrical contact without depending on the rotational angle of the rotating body 4 are connected. And is connected so as to be grounded from the slip ring 10. The slip ring 9 and the slip ring 10 are fixed to the rotating body 4 and rotate together with the rotating body 4.

  FIG. 2 is a schematic view of the magnetic force control body. 2A is a view of the magnetic force control body 8 as viewed from the front, and FIG. 2B is a view of the magnetic force control body 8 as viewed from the side. The magnetic force control body 8 is configured by winding a coil 12 around a magnetic material 11 serving as a magnetic shield so as to form a magnetic path for controlling the magnetic repulsion force of the magnetic field generating means 7. The magnetic material has a rectangular frame shape as shown in FIG. 2A, and has a circularly curved shape as shown in FIG. In the magnetic force control body shown in FIG. 2, the coil 12 is wound around the entire circumference of the magnetic material, but the coil 12 may be wound only on a part of the magnetic material. In the present embodiment, silicon steel having a relatively high magnetic permeability is used as a magnetic material having excellent controllability of magnetic repulsion force.

  Here, FIG. 3 shows a conceptual diagram in the case of shielding or passing the magnetic flux generated from the magnet which is the two functions of the magnetic force control body 8.

  FIG. 3A shows the magnetic field line distribution when a voltage is applied to the coil wound around the magnetic force control body 8 and the coil is energized. When a voltage is applied to the coil, the magnetic force control body 8 works so as to pass the magnetic flux generated from the magnet serving as the magnetic field generating means 7 due to a decrease in the magnetic permeability due to magnetic saturation. The magnetic flux passes through the magnetic force control body 8, and the magnetic flux leaks out of the magnetic force control body 8 as shown in FIG. Therefore, when the magnets are opposed to each other with the magnetic force control body 8 as the center, a magnetic repulsive force is generated.

  On the other hand, FIG. 3B shows the lines of magnetic force when no voltage is applied to the coil wound around the magnetic force control body 8. When no voltage is applied to the coil, the magnetic force control body 8 works to pass the magnetic flux generated from the magnet serving as the magnetic field generating means 7 through the magnetic force control body 8 by using the high magnetic permeability of the magnetic force control body. Since the magnetic flux passes through the magnetic force control body 8, it is difficult for the magnetic flux to leak out of the magnetic force control body 8 as shown in FIG. Therefore, even if the magnets are opposed to each other with the magnetic force control body as the center, no magnetic repulsive force is generated.

  FIG. 4 shows a schematic diagram of a control device for the magnetic force control body 8. As shown in FIG. 4, the control device includes a slip ring 9 that makes electrical contact according to a rotation angle, and the slip ring 9 includes a ring-shaped electrode 13, a brush 14, and a connection terminal 15. The ring-shaped electrode 13 is disposed so as to be in electrical contact according to the rotation angle. The slip ring 9 may be a commutator, and the number of electrodes may be plural.

  The coil 12 is connected to a slip ring 9 that is in electrical contact according to the rotation angle of the rotating body 4 and a slip ring 10 that is always in electrical contact without depending on the rotation angle of the rotating body 4; A positive voltage is supplied from the slip ring 9 and is connected to be grounded from the slip ring 10. The slip ring 9 and the slip ring 10 are fixed to the rotating body 4. Further, a DC power source 16 for energizing the coil 12 according to the rotation angle of the rotating body 4 is connected to the slip ring 9 serving as a control device.

  The number of turns of the coil 12 wound around the magnetic material 11 varies depending on the geometric shape such as the cross-sectional area and length of the magnetic material 11 and the amount of current flowing through the coil 12. It is sufficient that magnetic saturation occurs in the path portion 17. In particular, in order to reduce the amount of current flowing through the coil 12 in order to rotate the motor with energy saving, the winding thickness of the coil 12 is set to about 0.1 mm, and the magnetic material 11 has several tens to several hundreds. It is preferable to wind about once.

  FIG. 5 shows a schematic diagram of the control circuit of the magnetic force control body 8. The control circuit of the magnetic force control body 8 controls the coil 12 wound around the magnetic material 11 constituting the magnetic force control body 8 and the magnetic force control body 8 according to the rotation angle of the rotating body 4. The slip ring 9 serving as the control device and the DC power source 16 for energizing the coil 12 according to the rotation angle of the rotating body 4 are configured. The slip ring 9 is connected in series with the DC power source 16. The coil 12 is connected in parallel to both ends of the DC power supply 16 and the slip ring 9. The DC voltage supplied from the DC power supply 16 becomes a DC pulse voltage by being turned ON / OFF by the slip ring 9 according to the rotation angle of the rotating body 4. Since the direct-current pulse voltage is applied to the coil 8 as it is, the coil 12 is energized according to the rotation angle.

  With the above configuration, the operation of the magnetic rotating device of FIG. 1 in this embodiment will be described. FIG. 6 is a view of the magnetic rotating device of the present invention as viewed from the direction of the rotation axis, and shows the operation principle when the magnetic rotating device rotates in the right direction. 6 (A) and 6 (B) show the magnetic force control with the stator magnetic poles 7A and 7B, the rotor magnetic poles 7C and 7D arranged on the outer peripheral surface 5 and the peripheral surface 6 of the rotating body 4 before starting the magnetic rotating device. The example of arrangement | positioning of each body 8 is shown. Before starting, the DC power supply 16 needs to be energized. Further, when an electromagnet is used as the magnetic pole, it is necessary to energize the electromagnet before starting. The magnetic rotating device is started by applying an electric, magnetic or mechanical force for starting. The started magnetic rotator rotates using the repulsive force of the rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A and 7B arranged on the outer circumferential surface 5.

  FIG. 6C shows the rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body and the stator magnetic poles 7A and 7B arranged on the outer circumferential surface 5 when the magnetic rotating device generates a repulsive force as a rotational force. And an arrangement example of each of the magnetic force control bodies 8 are shown. In this embodiment, since the magnetic force control body 8 is fixed to the rotating shaft 2, the magnetic force control body 8 rotates with the rotation of the rotating body. As shown in FIG. 6C, the rotor magnetic pole 7C or 7D arranged on the circumferential surface 6 of the rotating body 4 passes through the stator magnetic pole 7A or 7B arranged on the outer circumferential surface 5 of the rotating body 4. At the rotation angle, the slip ring is brought into electrical contact at the rotation angle, whereby a voltage is applied from the DC power source 16 to the coil 12. Therefore, the voltage applied to the coil 12 is a DC pulse voltage corresponding to the rotation angle. When a voltage is applied to the coil 12, a current flows through the coil 12, the coiled magnetic material 11 is excited, and a magnetic path portion 17 is formed. At this time, a current sufficient to cause magnetic saturation of the magnetic path portion 17 to be formed is caused to flow through the coil 12, whereby the magnetic path portion 17 causes magnetic saturation, and thus the permeability of the magnetic path portion 17 changes. . The magnetic permeability of the magnetic path portion 17 is about several hundred to 1,000,000 H / m before the magnetic saturation occurs, but changes to 1 H / m or less after the magnetic saturation occurs.

  The magnetic force control body 8 before energizing the coil is between the rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A and 7B arranged on the outer circumferential surface 5 of the rotating body 4. While acting to shield the magnetism so as not to generate repulsive force, the magnetic force control body 8 after energizing the coil 12 and reducing the magnetic permeability of the magnetic path portion 17 to 1 H / m or less is magnetic Therefore, there is a repulsion between the stator magnetic poles 7A and 7B arranged on the outer peripheral surface 5 of the rotating body 4 and the rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body 4 so as not to exert a special effect. Power is generated.

  The repulsive force generated in the stator magnetic poles 7A and 7B and the rotor magnetic poles 7C and 7D can be expressed by the following equation which is the Coulomb law of magnetism.

Here, F [N] is the magnitude of the force acting between the magnetic poles, m ₁ [Wb] is the magnetic charge strength of the stator magnetic poles 7A and 7B, and m ₂ [Wb] is the magnetic charge of the rotor magnetic poles 7C and 7D. Strength, r [m] is the distance between both magnetic poles, and μ [H / m] is the magnetic permeability.

  By using the repulsive force thus obtained as a rotational force, the rotating body 4 rotates, and magnetic field generating means 7A, 7B, 7C, 7D disposed on the outer peripheral surface 5 and the circumferential surface 6 of the rotating body 4 The arrangement of the magnetic force control bodies 8 is as shown in FIG. As shown in FIG. 6D, the rotor magnetic pole 7C or 7D arranged on the circumferential surface 6 of the rotating body 4 passes through the stator magnetic pole 7A or 7B arranged on the outer circumferential surface 5 of the rotating body 4, and the stator Since the slip ring 9 is electrically insulated at the rotation angle within the range not affected by the magnetic force of the magnetic pole 7A or 7B, no current flows through the coil 12, so that the coil-wound magnetism Material 11 is demagnetized.

  By demagnetizing the magnetic material 11, the magnetic force control body 8 has the rotor magnetic poles 7 </ b> C and 7 </ b> D disposed on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7 </ b> A and 7 </ b> B disposed on the outer peripheral surface 5 of the rotating body 4. It works to shield the magnetism so that no repulsive force is generated between them. Since the magnetic force control body 8 acts to shield the magnetism, the rotor magnetic poles 7C and 7D disposed on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A and 7B disposed on the outer peripheral surface 5 of the rotating body 4 The rotating body 4 rotates without generating a repulsive force between the rotor magnetic poles 7C and 7D disposed on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A and 7B disposed on the outer peripheral surface 5 and the magnetic force. The arrangement of the control bodies 8 is as shown in FIG. 6C via FIG.

  That is, the rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body 4 and the outer periphery are controlled by controlling the magnetic force control body 8 with the slip ring 9 in accordance with the rotation angle with the DC power source 16 turned on. The repulsive force with the stator magnetic poles 7A and 7B arranged on the surface 5 is controlled, and can be rotated as shown in FIGS. 6 (C)-(D)-(E)-(C). . By turning off the DC power supply, the repulsive force by the magnetic field generating means 7 does not occur, so the rotating body 4 loses the rotating force and the magnetic rotating device stops.

  The magnetic force control body 8 may be disposed so as to shield the entire surface of all the stator magnetic poles 7A and 7B disposed on the outer peripheral surface 5 of the rotating body 4, and at least one pair is disposed so as to face each other. . A plurality of magnetic force control bodies 8 may be arranged as necessary. Further, in order to easily obtain a rotational force due to the magnetic repulsive force, a plurality of pairs of the stator magnetic poles 7A and 7B and the rotor magnetic poles 7C and 7D may be arranged as necessary.

  Further, a diode, a capacitor, or a resistor may be used in combination in order to prevent a back electromotive force or a contact spark that may occur during rotation.

  Furthermore, since the magnetic material 11 is magnetized by the hysteresis generated in the magnetic material 11 constituting the magnetic force control body 8 and hinders the rotational force, the magnetic force control body 8 is made of the soft magnetic material 11 having a relatively small hysteresis. It may be configured.

  In addition, it may be rotated left by applying an electric, magnetic or mechanical force in the left direction when starting the magnetic rotating device.

  7 shows the rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A arranged on the outer circumferential surface 5 of the rotating body 4 shown in the arrangement diagram of the magnetic rotating device in FIG. 7B is a graph showing the transition of the rotational force of the rotating body 4 with respect to the relative positions of 7B and the magnetic force control body 8. The rotational force of the rotating body 4 is a repulsive force generated between the rotor magnetic poles 7C, 7D disposed on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A, 7B disposed on the outer peripheral surface 5 of the rotating body 4. Including inertial force of rotation.

  In the graph, when the horizontal axis is (C), the rotor magnetic poles 7C and 7D disposed on the circumferential surface 6 of the rotating body 4, the stator magnetic poles 7A disposed on the outer circumferential surface 5 of the rotating body 4, 7B and the magnetic force control body 8 point out that it is the arrangement | positioning of FIG.6 (C), respectively. In the arrangement (C), the rotational force including the repulsive force and the rotational inertia force is maximized. With the rotation of the rotating body, the arrangement becomes arrangement (D) and arrangement (E). Since neither the arrangement (D) nor the arrangement (E) generates a repulsive force of the magnet, the rotational force is only an inertial force. Accordingly, the rotational force of the rotating body is attenuated. Although the rotational force is attenuated, the rotating body rotates again to the position of the arrangement (C), so that a cycle in which a repulsive force is generated again can be obtained. The rotating body can obtain a rotational force in this way.

  Note that, by minimizing the attenuation of the rotational force during this cycle, the rotational force can be kept substantially constant and the rotational speed can also be made substantially constant. Specifically, this can be solved by the arrangement of the rotor magnetic pole and the stator magnetic pole as in Example 5 described later.

  According to the magnetic rotating device of the present invention, a magnetic force rotating device having a relatively simple structure and suitable for miniaturization is provided by controlling the magnetic repulsion force of the permanent magnet by the magnetic force control body and the magnetic force controlling body control device. can do.

  A second embodiment of the magnetic rotating device according to the present invention is shown in FIG. In the present embodiment, a magnetic force rotating device fixed to the frame 1 is configured without fixing the magnetic force control body 8 shown in FIG.

  FIG. 8 shows a modification of the magnetic rotating device. In the present embodiment, since the magnetic force control body 8 is not fixed to the rotating shaft 2, the magnetic force control body 8 is supported by the bearing 3 and the rotating shaft 2.

  The configuration other than the support of the magnetic force control body 8 is substantially the same as in the first embodiment.

  With the configuration as described above, the operation of the magnetic rotating device in the present embodiment will be described. In this embodiment, since the magnetic force control body 8 is fixed to the frame 1, the magnetic force control body 8 does not rotate with the rotation of the rotating body 4.

  FIG. 9 is a view of the magnetic rotating device of the present invention as viewed from the direction of the rotation axis, and shows the operation principle when the magnetic rotating device rotates in the right direction. 9 (A) and 9 (B) show the magnetic poles and the stator magnetic poles 7A and 7B, the rotor magnetic poles 7C and 7D arranged on the outer circumferential surface 5 and the circumferential surface 6 of the rotating body 4 before starting the magnetic rotating device. The example of arrangement | positioning of each body 8 is shown. Before starting, the DC power supply 16 needs to be energized. In addition, when an electromagnet is used as the magnetic pole, it is necessary to energize before starting. The magnetic rotating device is started by applying an electric, magnetic or mechanical force for starting. The started magnetic rotator rotates using the repulsive force of the rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A and 7B arranged on the outer circumferential surface 5.

  FIG. 9C shows the rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body and the stator magnetic poles 7A and 7B arranged on the outer circumferential surface 5 when the magnetic rotating device generates a repulsive force as a rotational force. And an arrangement example of each of the magnetic force control bodies 8 are shown. In this embodiment, since the magnetic force control body 8 is fixed to the frame 1, the magnetic force control body 8 does not rotate with the rotation of the rotating body 4. As shown in FIG. 9C, the rotor magnetic pole 7C or 7D arranged on the circumferential surface 6 of the rotating body 4 passes through the stator magnetic pole 7A or 7B arranged on the outer circumferential surface 5 of the rotating body 4. At the rotation angle, the slip ring 9 is in electrical contact at the rotation angle, so that a voltage is applied from the DC power source 16 to the coil 12. Therefore, the voltage applied to the coil 12 is a DC pulse voltage corresponding to the rotation angle. When a voltage is applied to the coil 12, a current flows through the coil 12, the coiled magnetic material 11 is excited, and a magnetic path portion 17 is formed. At this time, a current sufficient to cause magnetic saturation of the magnetic path portion 17 to be formed is caused to flow through the coil 12, whereby the magnetic path portion 17 causes magnetic saturation, and thus the permeability of the magnetic path portion 17 changes. . The magnetic permeability of the magnetic path portion 17 is about several hundreds to 1,000,000 before the magnetic saturation occurs, but changes to 1 or less after the magnetic saturation occurs.

  The magnetic force control body 8 before energizing the coil is between the rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A and 7B arranged on the outer circumferential surface 5 of the rotating body 4. While the magnetic force control body 8 works to shield the magnetism so as not to generate a repulsive force, the magnetic force control body 8 after the coil 12 is energized and the permeability of the magnetic path portion 17 is reduced to 1 or less is a magnetic action. Therefore, the rotor magnetic poles 7C and 7D disposed on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A and 7B disposed on the outer peripheral surface 5 of the rotating body 4 are not affected by the above embodiment. A repulsive force similar to 1 is generated.

  By using the repulsive force thus obtained as a rotational force, the rotating body 4 rotates, and magnetic field generating means 7A, 7B, 7C, 7D disposed on the outer peripheral surface 5 and the circumferential surface 6 of the rotating body 4 The arrangement of the magnetic force control bodies 8 is as shown in FIG. As shown in FIG. 9D, the rotor magnetic pole 7C or 7D arranged on the circumferential surface 6 of the rotating body 4 passes through the stator magnetic pole 7A or 7B arranged on the outer circumferential surface 5 of the rotating body 4, and the stator Since the slip ring is electrically insulated at the rotation angle within a range not affected by the magnetic force of the magnetic pole 7A or 7B, no current flows through the coil 12, so that the coil-wrapped magnetic material 11 is demagnetized.

  By demagnetizing the magnetic material 11, the magnetic force control body 8 has the rotor magnetic poles 7 </ b> C and 7 </ b> D disposed on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7 </ b> A and 7 </ b> B disposed on the outer peripheral surface 5 of the rotating body 4. It works to shield the magnetism so that no repulsive force is generated between them. Since the magnetic force control body 8 acts to shield the magnetism, the rotor magnetic poles 7C and 7D disposed on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A and 7B disposed on the outer peripheral surface 5 of the rotating body 4 The rotating body 4 rotates without generating a repulsive force between the rotor magnetic poles 7C and 7D disposed on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A and 7B disposed on the outer peripheral surface 5 and the magnetic force. The arrangement of the control bodies 8 is as shown in FIG. 9C via FIG.

  That is, the rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body 4 and the outer peripheral surface are controlled by controlling the magnetic force control body 8 with the slip ring 9 according to the rotation angle with the DC power source turned on. 9 to control the repulsive force with the stator magnetic poles 7A and 7B arranged in FIG. 5, and rotate them as shown in FIG. 9 (C) -FIG. 9 (D) -FIG. 9 (E) -FIG. Can do. When the DC power supply 16 is turned off, the repulsive force by the magnetic field generating means 7 is not generated, so the rotating body 4 loses the rotating force and the magnetic rotating device stops.

  The magnetic force control body 8 may be disposed so as to shield the entire surface of all the stator magnetic poles 7A and 7B disposed on the outer peripheral surface 5 of the rotating body 4, and at least one pair is disposed so as to face each other. . A plurality of magnetic force control bodies 8 may be arranged as necessary. Further, in order to easily obtain a rotational force due to the magnetic repulsive force, a plurality of pairs of the stator magnetic poles 7A and 7B and the rotor magnetic poles 7C and 7D may be arranged as necessary.

  In addition, it may be rotated left by applying an electric, magnetic or mechanical force in the left direction when starting the magnetic rotating device.

Furthermore, the magnetic field generated between the coils can be canceled by winding the coils of one magnetic force control body 8 and the other magnetic force control body 8 so that the winding directions are opposite to each other. Can minimize the influence on the magnetic repulsive force that becomes the rotational force. In addition, by arranging two magnetic force control bodies 8, the size of each of the magnetic force control bodies 8A and 8B can be reduced, so that the magnetic path length of each of the magnetic force control bodies 8A and 8B can be shortened.

The magnetic force control body 8 is configured by winding a coil 12 around a magnetic material 11 serving as a magnetic shield so as to form a magnetic path for controlling the magnetic repulsion force of the magnetic field generating means 7. Further, the magnetic material has a shape in which rectangular frame-like bodies are connected as shown in FIG. 11A, and has a shape curved in a circle as shown in FIG. 11B.

  FIG. 12 shows a fifth embodiment of the magnetic rotating device according to the present invention. In the present embodiment, a magnetic rotating device is configured in which the stator magnetic poles 7A and 7B and the rotor magnetic poles 7C and 7D shown in FIG.

FIG. 12 shows a modification of the magnetic rotating device.
FIG. 12 shows a magnetic force rotating apparatus using the magnetic force control body 8 of FIG. 11 as the magnetic force control body 8 and arranging a plurality of rows of stator magnetic poles 7A and 7B and rotor magnetic poles 7C and 7D in the rotation axis direction. In this embodiment, three rows of stator magnetic poles 7A and 7B and rotor magnetic poles 7C and 7D are fixed to the rotary shaft 2 in the direction of the rotary shaft. Thereby, since the magnetic repulsive force obtained from the stator magnetic poles 7A and 7B and the rotor magnetic poles 7C and 7D is increased, the rotational force can be increased. In addition, since the time interval until the magnetic repulsive force is obtained is shortened by increasing the rotational force, the attenuation of the rotational force can be minimized.

  Of the stator magnetic poles 7A, 7B and the rotor magnetic poles 7C, 7D arranged in a plurality of rows with respect to the direction of the rotation axis, the rotation shafts so that at least one row of the stator magnetic poles 7A, 7B and the rotor magnetic poles 7C, 7D can be phased. You may arrange | position at a different angle with respect to a direction. For example, you may arrange | position so that a 45 degree phase may be made, and may arrange | position so that a 30 degree phase may be made. In the case where a plurality of rows of stator magnetic poles 7A and 7B and rotor magnetic poles 7C and 7D are arranged so as to achieve a phase, the magnetic force control body 8 is not fixed to the rotary shaft 2 in order to simplify the configuration of the magnetic force rotating device. The frame 1 is preferably fixed to the frame 1. Moreover, it is preferable to arrange | position the magnetic force control body 8 in the position which can be controlled for every row | line | column of the magnetic pole which has a phase. Furthermore, it is preferable that the slip ring 9 serving as a control device for the magnetic force control body 8 is configured to be controlled according to a rotation angle that does not hinder the magnetic repulsive force and the inertial force that are rotational forces.

  The configuration other than the stator magnetic poles 7A and 7B, the rotor magnetic poles 7C and 7D and the magnetic force control body 8 is substantially the same as that of the second embodiment.

  The operating principle when the magnetic rotating device rotates is substantially the same as in the second embodiment, and is the same as in FIG. FIG. 13 shows rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body 4 and stator magnetic poles 7A arranged on the outer circumferential surface 5 of the rotating body 4 shown in the arrangement diagram of the magnetic rotating device in FIG. 7B is a graph showing the transition of the rotational force of the rotating body 4 with respect to the relative positions of 7B and the magnetic force control body 8. The rotational force of the rotating body 4 is a repulsive force generated between the rotor magnetic poles 7C, 7D disposed on the circumferential surface 6 of the rotating body 4 and the stator magnetic poles 7A, 7B disposed on the outer peripheral surface 5 of the rotating body 4. Including inertial force of rotation.

  In the graph, when the arrangement arrangement which becomes the horizontal axis is (C), the rotor magnetic poles 7C and 7D arranged on the circumferential surface 6 of the rotating body 4 and the stator magnetic pole 7A arranged on the outer circumferential surface 5 of the rotating body 4. 7B and the magnetic force control body 8 indicate the arrangement shown in FIG. 9C. In the arrangement (C), the rotational force including the repulsive force and the rotational inertia force is maximized. As the rotating body 4 rotates, the arrangement becomes the arrangement (D) and the arrangement (E). Since neither the arrangement (D) nor the arrangement (E) generates a repulsive force of the magnet, the rotational force is only an inertial force, and thus the rotational force of the rotating body 4 is attenuated. Although the rotational force is attenuated, the rotating body 4 is rotated again to the position of the arrangement (C), so that a cycle in which a repulsive force is generated again is obtained. The rotating body 4 can obtain a rotational force in this way.

  In this embodiment, by using a plurality of stator magnetic poles 7A and 7B and rotor magnetic poles 7C and 7D, the obtained magnetic repulsive force can be increased, and the attenuation of the rotational force during the cycle can be minimized. As a result, the rotational force can be kept substantially constant, and the rotational speed can also be made substantially constant.
