Hereinafter, modes for carrying out the present invention will be described in detail with reference to the drawings.

FIG. 1A is a cross-sectional structural view showing the configuration of the magnet drive mechanism of the present embodiment, and FIG. 1B is a cross-sectional view of FIG. FIG. 1C is a perspective view showing the structure of the rotor, and FIG. 1D is a perspective view showing the structure of the switching element.

As shown in FIG. 1 (a), the rotor 20 includes a cylindrical body 20a having a plurality of magnets installed therein and a rotating shaft 20b. The rotor 20 is rotatably supported on the casing 60 by two bearings 40. Three switching elements A 30 a, switching elements B 30 b, and switching elements C 30 c are supported and held by a holding member 50 inside the cylindrical body 20 a of the rotor 20, and the switching element 30 is illustrated along the holding member 50. 1 (a) can be displaced by a predetermined distance in the left-right direction. The holding member 50 is fixed to the casing 60, and the holding member 50 and the switching element 30 do not rotate.

Next, the rotor 20 and the magnets installed in the three switching elements A 30a, the switching element B 30b, and the switching element C 30c will be described. As shown in FIG. 1C, the rotor 20 is provided with a magnet. That is, a plurality of N-pole and S-pole magnets are installed in half along the circumferential direction of the cylindrical body 20a, and such a ring of magnets is installed inside the cylindrical body 20a for four circumferences. On the other hand, the switching element 30 has a fan shape, and a plurality of N-pole and S-pole magnets are provided on the outer peripheral surface thereof as shown in FIG. That is, a plurality of N-pole magnets or a plurality of S-pole magnets are installed on the same circumference of the outer peripheral surface, and these N-pole magnets and S-pole magnets are arranged in the axial direction of the rotor 20. It is installed alternately. In FIG. 1 (d), 8 rows of magnets are installed in total including N and S poles. It is assumed that the distance between the N pole and S pole rows of the switching element 30 is the same as the gap between the magnet rows inside the cylindrical body 20a of the rotor 20. In the magnet motor of this embodiment, the three switching elements A 30a, switching element B 30b, and switching element C 30c are all the same.

Next, the arrangement of the magnets of the rotor 20 and the switching element 30 will be described. As shown in FIG. 1B, these three switching elements are installed at equal angular intervals every 120 °. The S pole magnet of switch A 30a faces the N pole magnet of rotor 20, and the N pole magnet of switch B 30b faces the S pole magnet of the rotor. Further, the N pole magnet of the switching element C 30c is opposed to both the N pole magnet and the S pole magnet of the rotor 20. Such switching of the facing state of the magnet can be performed by displacing a bar provided at the right end of the switching element to the left and right as shown in FIG. The upper switching element 30 in FIG. 1B is pushed into the left side of the drawing, and the lower switching element 30 in FIG. 1B is drawn to the right side in the drawing. In this manner, the facing state of the magnet can be changed by displacing the right end of the switching element 30 to the left and right. Various mechanisms can be considered as the drive mechanism for displacing the switching element 30 to the left and right. For example, an engine piston may be used.

[Rotational force acting on the rotor]
The rotational force acting on the rotor 20 will be described with reference to FIGS. 2-1 and 2-2. In (1) to (6) of FIG. 2-1, a plurality of N-pole magnets are opposed to a plurality of magnets of the rotor 20 in the switching element 30, and FIGS. 8) and (9) to (15) in FIG. 2-2, the S pole magnet is opposed to the magnet of the rotor 20 in the switch 30. In FIG. That is, between the state of FIG. 2-1 (6) and the state of FIG. 2-1 (7), the magnetic pole facing the magnet of the rotor 20 on the surface side of the switching element 30 is switched from the N pole to the S pole. It is assumed that the rotor 20 is rotating counterclockwise. Further, the inner magnetic pole of the magnet on the inner peripheral surface of the rotor 20 is the S pole on the downstream side (left side in FIG. 2-1) in the rotation direction and the N pole on the upstream side (right side in FIG. 2-1). .

In the state of FIG. 2-1 (1), the N-pole magnet on the surface of the switching element 30 and the S-pole magnet on the inner peripheral surface of the rotor 20 are opposed to each other. The boundary between the S-pole magnet and the N-pole magnet of the rotor 20 (the place where there is no magnet) is located upstream in the rotational direction in FIG. The force vector shown in the drawing represents the force acting on the magnet on the inner peripheral surface of the rotor 20 (in this case, the S-pole magnet). Of these force vectors, the force vector toward the center of rotation does not affect the rotation of the rotor 20 at all. On the other hand, the force vectors shown in bold of the total of four magnets on the left and right ends in FIG. 2-1 (1) affect the rotation. The two force vectors on the left side act as a brake for rotation, and the two force vectors on the right side act as a thrust for rotation. However, since the total values are equal, the state shown in FIG. Then it will not affect the rotation.

FIG. 2-1 (2) shows a state in which the rotation of the rotor 20 has progressed counterclockwise by one magnet from the state of FIG. 2-1 (1). In the subsequent drawings, similarly, it is assumed that the rotation of the rotor 20 proceeds by one magnet. In FIG. 2A, the vector component of the brake force is larger, and the brake starts to act on the rotor 20 as a whole. In FIG. 2-1 (3), the brake is further increased. In FIG. 2-1 (4), the N-pole magnet of the rotor 20 also acts as a brake, and in FIG. 2-1 (5), the brake reaches the maximum value. Thereafter, the brake does not change until the state of FIG. Next, the switch 30 is switched between the state of FIG. 2-1 (6) and the state of FIG. 2-1 (7). That is, the state where the N pole magnet of the switching element 30 faces the magnet of the rotor 20 is switched to the state where the S pole magnet of the switching element 30 faces the magnet of the rotor 20.

In FIG. 2-1 (7), since the magnet facing the magnet of the rotor 20 is the S pole, a large thrust in the rotating direction acts on the rotor 20. This large thrust continues until FIG. 2-2 (11). This thrust gradually decreases and the thrust and the brake are balanced in FIG. 2-2 (15). A resistance force is generated to change the state of FIG. 2-1 (6) to the state of FIG. 2-1 (7). This resistance force will be described in detail later.

The rotational force acting on the rotor 20 is summarized as follows. Note that the following description will be made assuming that the thrust is Fa, the braking force is Fb, and the smallest value is 1.
(Figure 2-1)
(1) Fb = 0, (2) Fb = 1, (3) Fb = 2, (4) Fb = 3
(5) Fb = 4, (6) Fb = 4
(Figures 2-1 and 2-2)
(7) Fa = 4, (8) Fa = 4, (9) Fa = 4, (10) Fa = 4
(11) Fa = 4, (12) Fa = 3, (13) Fa = 2, (14) Fa = 1,
(15) Fa = 0

[Resistance of switching element]
Next, the force necessary for linearly displacing the switching element 30 in the direction of the rotation axis (hereinafter referred to as “resistance force”) will be described below.

First, the resistance in the case of Fig. 2-1 (1) will be described. The state of FIG. 2-1 (1) is shown again in FIG. 3-1 (a). FIG. 3-1 (b) is a view as viewed from A in FIG. 3-1 (a) and shows a state where the switch 30 has moved slightly downward in the figure. FIG. 3-1 (d) is a side view of FIG. 3-1 (b). FIG. 3C is a side view of the state before the switching element 30 moves. In this case, ten S-pole magnets exist on the inner peripheral surface of the outer rotor 20, and ten N-pole magnets exist on the outer peripheral surface of the inner switch 30. Since these ten S-pole and N-pole magnets are different poles, they are attracted to each other by an attractive force (see FIGS. 3-1 (a) and 3-1 (c)). Next, what kind of resistance force is necessary when the switch 30 is displaced in the direction of the rotation axis from this state will be considered. First, as shown in FIG. 3C, the ten N-pole magnets on the lower side of the switch 30 are pulled toward the rotor 20, and the S-pole magnet on the upper side of the switch 30 is The rotor 20 is in a state of receiving a repulsive force (repulsive force) from the S pole magnet of the rotor 20 although the size is small. Consider a state in which the switch 30 is pushed downward further from this state (FIG. 3-1 (d)).

3-1 (b) and (d) are cases where the upper and lower boundaries of the two-stage magnet of the switching element 30 have moved to the position of the vertical center line of the rotor 20 magnet. In this case, the N-pole magnet of the switching element 30 still receives the attractive force from the S-pole magnet of the rotor 20, but the value is far away, so that the case of FIG. 3-1 (c) It becomes a smaller value. On the other hand, since the S pole magnet at the upper stage of the switching element 30 is closer to the S pole magnet of the rotor 20, it receives a larger repulsive force than in the case of FIG. Eventually, the N-pole (lower stage) and S-pole (upper stage) magnets of the switching element 30 receive approximately the same amount of attractive force and repulsive force from the S-pole magnets of the rotor 20. That is, if the switching element 30 is displaced in the direction of the rotation axis, a very large resistance force is received. In this case, since there are 10 sets of magnets in the upper and lower two stages in the switch 30, when the force received by one set of magnets is 1 and the resistance is R, the resistance is R = 10. It will be. After all, in order to displace the switching element 30 in the direction of the rotation axis in the state of FIG. 2-1 (1), a very large force is required.

Next, the resistance force when switching from the state of FIG. 2-1 (6) to the state of FIG. 2-1 (7) will be described. The state of FIG. 2-1 (6) is shown again in FIG. 3-2 (a). FIG. 3-2 (b) is a view as viewed from A in FIG. 3-2 (a) and shows a state where the switch 30 has moved slightly. FIG. 3-2 (c) is a side view of the left part of FIG. 3-2 (a). FIG. 3-2 (d) is a side view of the state (FIG. 3-2 (b)) in which the switch 30 has moved slightly downward from the state of FIG. 3-2 (c). FIG. 3-2 (e) is a side view of the right portion of FIG. 3-2 (a). FIG. 3-2 (f) is a side view of the state (FIG. 3-2 (b)) in which the switch 30 has moved slightly downward from the state of FIG. 3-2 (e). In the case of FIG. 3-2 (a), there are five S-pole magnets and three N-pole magnets on the inner circumferential surface of the outer rotor 20, and the outer circumferential surface of the inner switching element 30. There are 10 N-pole magnets. However, among the 10 N-pole magnets on the outer peripheral surface of the switching element 30, the eight N-pole magnets actually face the rotor 20 magnet.

That is, the five S-pole magnets of the rotor 20 are opposed to the five N-pole magnets of the switch 30, and the three N-pole magnets of the rotor 20 are the three N-poles of the switch 30. It will be opposed to the magnet. Then, as in the case of FIG. 2-1 (1), what kind of resistance force is generated when the switch 30 is displaced in the direction of the rotation axis is considered. First, the five sets of S-pole and N-pole magnets of the left rotor 20 and the switch 30 have resistance acting on the switch 30 as in the case of FIG. 2-1 (1) already described. The resistance value is 5.

On the other hand, the force when the three N-pole magnets of the right rotor 20 are opposed to the three N-pole magnets of the switching element 30 will be described. First, the state before the switch 30 is displaced in the direction of the rotation axis is shown in FIG. In this state, the lower N pole magnet of the switching element 30 is repelling the N pole magnet of the rotor 20, and the upper S pole magnet of the switching element 30 is the N pole magnet of the rotor 20. Is attracting. This attracting force is not as great as the repulsive force (repulsive force). Next, FIG. 3-2 (f) shows a state in which the switching element 30 is slightly displaced in the direction of the rotation axis from this state. This state is a case where the upper and lower boundaries of the two-stage magnet of the switching element 30 have moved to the position of the center line in the vertical direction of the magnet of the rotor 20. In this case, the N-pole magnet of the switching element 30 still receives repulsive force from the N-pole magnet of the rotor 20, but the value is far away from that of FIG. 3-2 (e). Small value. On the other hand, since the S pole magnet at the upper stage of the switching element 30 is closer to the N pole magnet of the rotor 20, it receives a larger pulling force than in the case of FIG. Eventually, the N-pole (lower stage) and S-pole (upper stage) magnets of the switching element 30 receive the same amount of attractive force and repulsive force from the N-pole magnets of the rotor 20. That is, when the switch 30 is displaced in the direction of the rotation axis, a force in the same direction (forward direction) as the displacement direction is received. The magnitude of this forward force is 3 because there are 3 sets of N-pole and S-pole magnets.

In the case of FIG. 2-1 (6), since the resistance value is 5 and the magnitude of the forward force is 3, a resistance force of R = 2 is eventually generated. This can be said to be a force that resists the force of the two sets of magnets on the left side from the center line of the switching element 30.

After all, in order to change the state of FIG. 2-1 (6) to the state of FIG. 2-1 (7), that is, to displace the switch 30 in the direction of the rotation axis, a force against the resistance force of R = 2 is required. I need it. It can be seen that this is a much smaller force than in the case of the resistance force R = 10 in FIG.

Next, resistance will be described in the case of Fig. 2-1 (8). The state of FIG. 2-1 (8) is shown again in FIG. 3-3 (a). FIG. 3-3 (b) is a view A of FIG. 3-3 (a) and shows a state where the switch 30 has moved slightly. FIG. 3-3 (c) is a side view of the left part of FIG. 3-3 (a). FIG. 3-3 (d) is a side view of the state (FIG. 3-3 (b)) in which the switch 30 has moved slightly downward from the state of FIG. 3-3 (c). FIG. 3-3 (e) is a side view of the right portion of FIG. 3-3 (a). FIG. 3-3 (f) is a side view of the state (FIG. 3-3 (b)) in which the switch 30 has moved slightly downward from the state of FIG. 3-3 (e).

In the state of FIG. 3-3 (a), there are four S-pole magnets and four N-pole magnets on the inner peripheral surface of the outer rotor 20, and on the outer peripheral surface of the inner switch 30. There are 10 N pole magnets. However, among the 10 N-pole magnets on the outer peripheral surface of the switching element 30, the eight N-pole magnets that are actually opposed to the magnet of the rotor 20. That is, the four S pole magnets of the rotor 20 are opposed to the four N pole magnets of the switch 30, and the four N pole magnets of the rotor 20 are the four N poles of the switch 30. It will be opposed to the magnet. Then, as in the case of FIG. 2-1 (1), what force is necessary when the switch 30 is displaced in the direction of the rotation axis will be considered. First, the four sets of S-pole and N-pole magnets of the left rotor 20 and the switch 30 have the same resistance as in the case of FIGS. 2-1 (1) and (7) already described. Resistance force R = 4.

On the other hand, the force when the four N-pole magnets on the right side of the rotor 20 are opposed to the four N-pole magnets of the switching element 30 will be described. In this case, assuming that the three sets of N poles on the right side of FIG. 2-1 (7) are facing each other, a forward force is generated and the magnitude thereof is 4. After all, in the case of FIG. 2-1 (8), since the resistance value is 4 and the magnitude of the forward force is 4, the force for displacing the switching element 30 in the rotational axis direction is basically unnecessary. It can be seen that it is. The resistance force R required to displace the switching element 30 in the rotation axis direction is as follows.
(Figure 2-1)
(1) R = 10, (2) R = 10, (3) R = 9, (4) R = 8
(5) R = 6, (6) R = 4, (7) R = 2, (8) R = 0

[Rotating force when the switch is in the middle position]
(1) FIG. 2-1 (7) shows the state after the magnet facing the rotor 20 of the switching element 30 has changed from the N pole to the S pole. Described below. FIG. 4A shows this intermediate state. 4B shows a state where the upper S pole magnet of the switching element 30 faces the rotor 20, and FIG. 4C shows a lower N pole magnet of the switching element 30. Shows a state of facing the rotor 20.

In the state of FIG. 4-1 (b), the force of thrust Fa = 4 acts on the rotor 20, and in the state of FIG. 4-1 (c), the brake force Fb = 4 acts on the rotor 20. After all, when the switching element 30 in FIG. 4A is in the intermediate position, no force in the rotational direction is generated on the rotor 20.

(2) FIG. 2-1 (8) shows the state after the magnet facing the rotor 20 of the switching element 30 has changed from the N pole to the S pole. Described below. FIG. 4-2 (a) shows this intermediate state. 4B shows a state in which the upper S pole magnet of the switching element 30 faces the rotor 20, and FIG. 4-2C shows a lower N pole magnet of the switching element 30.

Note that the state shown in FIG. 4-2 is considered because the switching of the switch 30 in the direction of the rotation axis may be delayed and the switching may be completed in the state after FIG. 2-1 (8). is there. In this case, the force required for switching is small, but a large rotational force cannot be obtained.

[Rotation control of magnet drive mechanism]
The rotation control of the magnet drive mechanism of the present embodiment will be described below with reference to FIG.

FIGS. 5 (a) to 5 (h) show a state in which the rotor 20 is sequentially rotated with the movement of the three switching elements A 30a, B, 30b, and C 30c.

First, the positional relationship between the rotor 20 and the three switching elements A 30a, switching element B 30b, and switching element C 30c will be described with reference to FIG. Since each position is determined by the angle, the angle is defined. In FIG. 5A, the angle above the rotation center is 0 °. And it defines as 90 degrees, 180 degrees, and 270 degrees counterclockwise. The center of switch A 30a is at the 0 ° position, the center of switch B 30b is at the 120 ° position, and the center of switch C 30c is at the 240 ° position. This position is unchanged, and the switch 30 is only displaced in a direction perpendicular to the paper surface. By displacing in the direction perpendicular to the paper surface, the pole of the magnet facing the magnet of the rotor 20 can be switched from the N pole to the S pole or from the S pole to the N pole. An S-pole magnet is installed on the left inner peripheral surface of the rotor 20 and an N-pole magnet is installed on the right inner peripheral surface. In the state shown in FIG. It is assumed that the upper boundary of the N pole magnet and the N pole magnet is at the position of θ clockwise from the position of 0 °. The rotor 20 rotates counterclockwise.

Note that the magnitude of θ can be freely determined. If the magnitude of θ is increased, a large force is required to displace the switching element A 30a. However, a large force can be applied to the rotor 20 and a large rotational force can be obtained. Furthermore, the value of θ may be negative, that is, a position deviated counterclockwise from 0 °. That is, switching of the switch A 30a may be started before 0 °, and the switching may be completed at a position exceeding 0 °. Even in this case, since the braking force can be reduced, the rotor 20 can be rotated continuously.

Switcher A 30a is facing the N pole magnet, Switcher B 30b is facing the N pole magnet, Switcher C 30c is facing the S pole magnet and the rotor 20 magnet. Only the force in the direction of the rotation center is generated in the magnet of the rotor 20 facing the switch B 30b and the switch C 30c, and the rotation of the rotor 20 is not affected. On the other hand, the brake force B = 4 acts on the magnet of the rotor 20 facing the switch A 30a as described above. Further, in order to displace the switch A 30a in FIG. 5A, a force that opposes the resistance force 2 must be applied to the switch A 30a.

FIG. 5 (b) shows a state after the switch A 30a is displaced by applying a force against the resistance force 2. FIG. That is, in the switching element A 30a, the magnet facing the rotor 20 is an S-pole magnet. As a result, a force of thrust 4 acts on the rotor 20 in the counterclockwise direction.

After all, by displacing the switching element A 30a against the resistance force 2 in the state of FIG. 5A, the time during which the braking force acting on the rotor 20 acts can be shortened, and the thrust 4 works. The time can be lengthened. As a result, the rotor 20 can rotate continuously. In other words, it can be said that the force applied to the switching element A 30a is converted to the force that turns the rotor 20. Note that there is no change in the state of the switch B 30b and the switch C 30c. Due to the counterclockwise force, the rotor 20 changes from the state shown in FIG. 5B to the state shown in FIG.

FIG. 5C shows a state in which the rotor 20 is rotated 60 ° counterclockwise. In this state, a braking force acts on the magnet of the rotor 20 facing the switching element C 30c. This is the same state as the magnet of the rotor 20 facing the switch A 30a in FIG. In addition, the rotational force is no longer applied to the magnet facing the switching element A 30a of the rotor 20, and only the force in the direction of the rotation center is applied. The force acting on the magnet facing the switching element B 30b of the rotor 20 is the same as the force acting on the magnet facing the switching element B 30b in the state of FIGS. 5 (a) and 5 (b). In FIG. 5C, the S pole magnet of the switching element C 30c faces the magnet of the rotor 20, but the switching element C 30c is placed so that the N pole magnet faces the magnet of the rotor 20. Displace. The state after the displacement is the state shown in FIG. At the moment when the switching element C 30c is in the state shown in FIG. 5D, a rotational force is applied to the rotor 20 to rotate it counterclockwise. In this case, the state of the switch A 30a and the switch B 30b does not change.

FIG. 5 (e) shows a state in which the rotor 20 is further rotated by 60 °, that is, 120 ° from the state of FIG. 5 (a) by the rotational force shown in FIG. 5 (d). In this state, the brake is acting on the magnet of the rotor 20 facing the switching element B 30b. Further, only the force in the central direction acts on the location of the rotor 20 facing the switch A 30a and the switch C 30c. In this state, the switch B 30b is switched. That is, the N pole magnet of the switching element B 30 b is opposed to the magnet of the rotor 20 so that the S pole magnet is opposed to the magnet of the rotor 20. FIG. 5F shows a state after the switch B 30b is switched. Thereafter, the same switching is performed to sequentially switch the switching element 30 and rotate the rotor 20. In the above-described embodiment, the switch A 30a, the switch B 30b, and the switch C 30c only move to the left and right, and the rotor 20 rotates, but on the contrary, the rotor 20 is fixed. Alternatively, a configuration in which the switch A 30a, the switch B 30b, and the switch C 30c are rotated may be employed. The same applies to the following embodiments.

According to the magnet drive mechanism of the present embodiment, a sufficient rotational force can be generated in the rotor, and a predetermined rotational force can be applied to the rotor by changing the drive force of the switching element. .

FIG. 6A is a cross-sectional structural view showing the configuration of the magnet drive mechanism of the present embodiment, and FIG. 6B is a cross-sectional view of FIG. 6A. FIG. 6C is a perspective view showing the structure of the rotor 22, and FIG. 6D is a perspective view showing the structure of the switching element 32.

As shown in FIG. 6 (a), the rotor 22 includes a cylindrical body 22a having a magnet installed on the outside and a rotating shaft 22b. The rotor 22 is rotatably supported on the casing 60 by two bearings 40. Three switching elements A 32a, switching element B 32b, and switching element C 32c are supported and held by the casing 60 outside the cylindrical body 22a of the rotor 22, and the switching element 32 is shown in FIG. Although it can be displaced by a predetermined distance in the left-right direction of a), it does not rotate.

Next, the magnets installed on the rotor 22 and the three switching elements 32 will be described. As shown in FIG. 6C, the rotor 22 is provided with a magnet. That is, a plurality of N-pole and S-pole magnets are installed in half along the circumferential direction of the cylindrical body, and so-called magnet rings are installed on the outside of the cylindrical body for four circles. On the other hand, the switching element 32 has a fan-shaped shape, and a plurality of N-pole and S-pole magnets are installed on its inner peripheral surface as shown in FIG. That is, a magnet having only N poles or a magnet having only S poles is installed on the same circumference of the inner peripheral surface, and these N pole magnets and S pole magnets are alternately installed in the axial direction of the rotor 22. Has been. In FIG. 6 (d), eight rows of magnets are installed in total including N and S poles. The interval between the N pole and S pole rows is the same as the interval between the magnet rows outside the cylindrical body 22a of the rotor 22. In the magnet drive mechanism of the present embodiment, all three switching elements 32 are the same.

Next, switching control between the magnet of the rotor 22 and the magnet of the switching element 32 will be described. The three switching elements 32 are installed at equal angular intervals every 120 °. This installation state is the same as in the first embodiment. As shown in FIG. 6 (b), the S pole magnet of the switch A 32a faces both the N pole magnet and the S pole magnet of the rotor 22, and the S pole magnet of the switch B 32b rotates. Opposite to the south pole magnet of the child 22. Further, the N pole magnet of the switching element C 32 c faces the N pole magnet of the rotor 22. Such switching of the facing state of the magnet can be performed by displacing a bar provided at the right end of the switching element 32 to the left and right as shown in FIG. The upper switch 32 in FIG. 6A is pushed to the left in the figure, and the lower switch 32 in FIG. 6A is pulled to the right in the figure. In this manner, the facing state of the N-pole magnet and the S-pole magnet can be changed by displacing the right end of the switching element 32 to the left and right.

[Rotation control of magnet drive mechanism]
The rotation control of the magnet drive mechanism of the present embodiment will be described below with reference to FIG. FIGS. 7A to 7H show a state in which the rotor 22 sequentially rotates in accordance with the movement of the three switching elements A 32a, switching element B 32b, and switching element C 32c.

First, the positional relationship between the rotor 20 and the three switching elements A 32a, switching element B 32b, and switching element C 32c will be described with reference to FIG. Since each position is determined by the angle, the angle is defined. In FIG. 7A, the angle above the rotation center is 0 °. And it defines as 90 degrees, 180 degrees, and 270 degrees counterclockwise. The center of the switch A 32a is at the 0 ° position, the center of the switch B 32b is at the 120 ° position, and the center of the switch C 32c is at the 240 ° position. This position is unchanged, and the switch 32 is only displaced in the direction perpendicular to the paper surface. By displacing in the direction perpendicular to the paper surface, the pole of the magnet facing the magnet of the rotor 22 can be switched from N pole to S pole or from S pole to N pole. An S-pole magnet is installed on the left outer peripheral surface of the rotor 22 and an N-pole magnet is installed on the right outer peripheral surface. However, in the state shown in FIG. It is assumed that the upper boundary of the pole magnet is at a position of θ clockwise from a position of 0 °. Note that the rotor 22 rotates counterclockwise.

Note that the magnitude of θ can be freely determined. Increasing the magnitude of θ requires a large force to displace the switching element A 32a. However, a large force can be applied to the rotor 22 and a large rotational force can be obtained. Furthermore, the value of θ may be negative, that is, a position deviated counterclockwise from 0 °. That is, switching of the switch A 32a may be started before 0 °, and the switching may be completed at a position exceeding 0 °. Even in this case, since the braking force can be reduced, the rotor 22 can be continuously rotated.

In FIG. 7A, the switch A 32a faces the N pole magnet, the switch B 32b faces the N pole magnet, and the switch C 32c faces the S pole magnet. . Only the force in the center direction is generated in the magnet of the rotor 22 facing the switch B 32b and the switch C 32c, and the rotation of the rotor 22 is not affected. On the other hand, the brake force B = 4 is acting on the portion of the rotor 22 facing the switch A 32a as described above. Further, in order to displace the switch A 32a in FIG. 7A, a force that opposes the resistance force 2 must be applied to the switch A 32a.

FIG. 7B shows a state after the switch A 32a is displaced by applying a force against the resistance force 2. That is, in the switching element A 32a, the magnet facing the rotor 22 is an S-pole magnet. As a result, a force of thrust 4 acts on the rotor 22 counterclockwise.

That is, in the state of FIG. 7 (a), by displacing the switching element A 32a against the resistance force 2, the time during which the braking force acting on the rotor 22 acts can be shortened, and the thrust 4 works. The time can be lengthened. As a result, the rotor 22 can rotate continuously. In other words, it can be said that the force applied to the switching element A 32a is converted into a force for turning the rotor 22. There is no change in the state of the switch B 32b and the switch C 32c. Due to the counterclockwise force, the rotor 22 changes from the state shown in FIG. 7B to the state shown in FIG.

FIG. 7C shows a state in which the rotor 22 is rotated 60 ° counterclockwise. In this state, a braking force is applied to the magnet of the rotor 22 facing the switching element C 32c. This is the same state as the magnet of the rotor 22 facing the switch A 32a in FIG. In addition, the rotational force no longer acts on the magnet at the location of the rotor 22 facing the switching element A 32a, and only the force in the center direction of the rotor 22 acts. In addition, about the force which acts on the magnet of the location facing the switching element B 32b of the rotor 22, the force which acts on the magnet of the location facing the switching element B 32b in the state of FIG. 7 (a), (b) The same. In FIG. 7C, the S pole magnet of the switch C 32c faces the magnet of the rotor 22, but the switch C 32c is placed so that the N pole magnet faces the magnet of the rotor 22. Displace. The state after the displacement is the state of FIG. At the moment when the switch C 32c is in the state shown in FIG. 7D, a rotational force is applied to the rotor 22 to rotate it counterclockwise. In this case, the state of the switch A 32a and the switch B 32b does not change.

FIG. 7 (e) shows a state in which the rotor 22 is further rotated by 60 °, that is, 120 ° from the state of FIG. 7 (a) by the rotational force shown in FIG. 7 (d). In this state, the brake is acting on the magnet of the rotor 22 facing the switching element B 32b. Further, only the force in the central direction acts on the location of the rotor 22 facing the switch A 32a and the switch C 32c. In this state, the switch B 32b is switched. That is, the N pole magnet of the switching element B 32b is opposed to the magnet of the rotor 22 so that the S pole magnet is opposed to the magnet of the rotor 22. FIG. 7F shows a state after the switching element B 32b is switched. Thereafter, the same switching is performed to sequentially switch the switching element 32 and rotate the rotor 22. In the above-described embodiment, the switch A 32a, the switch B 32b, and the switch C 32c are only displaced to the left and right, and the rotor 22 rotates, but on the contrary, the rotor 22 is fixed. The switch A 32a, the switch B 32b, and the switch C 32c may be rotated. The same applies to the following embodiments.

This example will be described below with reference to FIG. The magnet drive mechanism of the present embodiment is a magnet drive mechanism having a configuration in which the magnet drive mechanism of the first embodiment and the magnet drive mechanism of the second embodiment are integrated.

In the rotor 24 of the present embodiment, the magnets are installed on both the inner peripheral surface and the outer peripheral surface of the rotor 24. That is, the rotor 24 receives rotational force on both the inner peripheral surface and the outer peripheral surface, and as a result, a remarkably large rotational torque can be generated as compared with the magnet drive mechanisms of the first and second embodiments.

Further, the switching element 34 is installed inside and outside the rotor 24, and the inner switching element 34 and the outer switching element 34 are connected as shown in the figure and are displaced at the same timing. The arrangement of the three switching elements A 34a, switching element B 34b, and switching element C 34c in the rotational direction, the magnet installation method, the timing for displacing the switching elements, and the like are the same as in the first and second embodiments, and the description thereof is omitted. .

The magnet drive mechanism of the present embodiment is substantially the same size as the magnet drive mechanisms of

Embodiments

1 and 2, but can generate a larger rotational torque.

Unlike the magnet motors of the first to third embodiments, the present embodiment relates to a magnet drive mechanism that moves the moving plate by switching the moving plate on which the magnet is installed with the switching plate on which the magnet is also installed. .

The configuration of the drive mechanism of this embodiment will be described with reference to FIG. This magnet drive mechanism drives the moving plate 100 in which the S-pole and N-pole magnets are installed as shown in FIG. The individual magnets are separate and independent. There is a predetermined distance between the S pole magnet and the N pole magnet. In the drawing, the S pole magnet on the left end side of the S pole magnet and the N pole magnet on the right end side of the N pole magnet are omitted. This moving plate 100 corresponds to the rotor 20 of the first embodiment.

On the other hand, on the switching plate 110, S-pole and N-pole magnets are installed in two rows in parallel. The switching plate 110 is installed in parallel with the moving plate 100 so that the magnet surface thereof faces the magnet surface of the moving plate 100. The switch plate 110 corresponds to the switch 30 of the first embodiment. FIGS. 9C and 9D show the states of the opposing magnets only with the magnets of the moving plate 100 and the switching plate 110. 9C, the N-pole magnet of the switching plate 110 is opposed to the magnet of the moving plate 100, and in FIG. 9D, the S-pole magnet of the switching plate 110 is opposed to the magnet of the moving plate 100. Indicates that When the switching plate 110 is displaced in the arrow direction in FIG. 9C, the state shown in FIG. 9D is obtained.

FIGS. 10-1 and 10-2 are diagrams for illustrating the operating principle of the magnet drive mechanism of the present embodiment. Basically, it is the same as the contents of FIGS. 2-1 and 2-2 described in the first embodiment, and the state in which FIGS. 2-1 and 2-2 are straightly straightened is shown in FIGS. It can be considered as shown in FIG. Note that the state of the switching plate 110 in (1) to (6) of FIG. 10-1 is the state of FIG. 9C, and the state of the switching plate 110 in (7) to (15) of FIG. This is the state of FIG.

10-1 and 10-2, the moving plate 100 is moved from right to left in the figure, and the position of the switching plate 110 is not changed. However, the switching plate 110 is displaced in the direction perpendicular to the paper surface. Then, the switching plate 110 is switched between FIGS. 10-1 (6) and 10-1 (7) so that the N-pole magnet faces the moving plate 100 so that the S-pole magnet faces. To. In this state, a large driving force is generated. Since the direction of force generation, the magnitude of the force, and the like are the same as those in the first embodiment, description thereof is omitted. In the above example, the switching plate 110 is switched between FIGS. 10-1 (6) and 10-1 (7), and the N-pole magnet is opposed to the moving plate 100. Although the magnets are opposed to each other, for example, the switching plate 110 may be switched between FIGS. 10-1 (5) and 10-1 (6). By doing so, a larger force is required for switching, but a larger force can be applied to the moving plate 100.

In FIG. 9, the magnet row of the moving plate 100 is described as one row, and the magnet row of the switching plate 110 is described as two rows, but both may be a plurality of rows as in the first embodiment. In this way, a greater driving force can be obtained.

If the drive mechanism described above is used, a moving mechanism can be configured to replace the belt conveyor installed in the factory. A plurality of switching plates 110 may be installed on the moving track at predetermined intervals, and the moving plate 100 may be moved sequentially, or the plurality of moving plates 100 may be moved sequentially. Further, the moving plate 100 may be fixed and the switching plate 110 may be moved.

According to the magnet drive mechanism of this embodiment, a sufficient force can be generated on the moving plate, and a predetermined thrust can be applied to the moving plate by changing the driving force of the switching element.
