Next, the permanent magnet units 5 1 and 5 2 attached to the main port 44 of the power generator 40 according to the present invention will be described in detail. Since the first and second permanent magnet units 5 1 and 5 2 differ only in the direction of the magnetic poles, they will be described collectively as the permanent magnet unit 10 below.

FIG. 6 is a perspective view of the permanent magnet unit 10 used in the power generator 40 of the present invention. FIG. 7 is a cross-sectional view taken along the line AA of the permanent magnet unit 10 shown in FIG.

The permanent magnet unit 10 according to the present embodiment includes magnet bodies 12 having magnetic poles at both ends in the thickness direction. The magnet body 12 is a magnet coupling body in which the plate-like permanent magnets 12 A to 12 H are mutually attracted and integrated. The magnet body 1 2 has a plurality of The plate-like permanent magnets 12 A to 12 2 H are not integrated with each other, but can be constituted by one member.

In addition, the permanent magnet unit 10 is provided on one end face (upper end face) 13 side of the magnet body 12 so as to have a predetermined angle with respect to the upper end face 13. And a roof-shaped member 30 (corresponding to the first yoke of the present invention). The permanent magnet unit 10 has a plate-like base end side yoke 16 (corresponding to the second yoke of the present invention) adsorbed on the other end face (lower end face) 15 of the magnet body 12. I have.

The permanent magnet unit 10 includes a fastening bolt 20 for integrally connecting the magnet body 12, the roof-shaped member 30, and the base end side yoke 16. Hereinafter, in the description of the permanent magnet unit 10, the roof-shaped member 30 side is up, and the base end side yoke 16 side is down. In addition, the center line of the magnet body 12 of the permanent magnet unit 10 is defined as an axis line (indicated by a two-dot chain line).

Hereinafter, each member constituting the permanent magnet unit 10 will be described. FIG. 8 is a perspective view of one plate-like permanent magnet 12 A constituting the magnet body 12 of the permanent magnet unit 10. As shown in FIG. 8, the plate-shaped permanent magnet 12 A has a disk shape with a flat upper and lower surface, and a bolt hole 21 that penetrates from the upper surface to the lower surface is formed in the center. The diameter of the plate-like permanent magnet 1 2 A is D. The plate-like permanent magnet 12 A is made of, for example, a neodymium magnet (Ne-Fe-Co), and one surface (for example, the upper surface) has an S pole and the other surface (for example, the lower surface) has an N pole. A neodymium magnet is preferable in that it has a large residual magnetic flux density and a large coercive force and can generate a strong magnetic field. The other plate-like permanent magnets 1 2 B to 1 2 H have the same shape and material. The plate-like permanent magnets 12 A to 12 H are mutually adsorbed to form a magnet body 12.

The shape of the plate-like permanent magnets 12 A to 12 2 H may be a plate shape, and is not limited to a disk shape. For example, it may be a quadrilateral or other polygons. Also magnet The material is not limited to neodymium, but may be samarium, cerium, alnico, or ferrite. However, since neodymium is the strongest magnet, it is preferable to use it.

The number of the plate-shaped permanent magnets to be overlapped is determined by the set height of the magnet body 12 and the thickness of one plate-shaped permanent magnet to be used. By changing the number of plate-like permanent magnets, the height (thickness) of the magnet body 12 can be easily changed. The whole can be made into one permanent magnet.

In this embodiment, the number of plate-like permanent magnets is eight, but other numbers may be used. If the number of plate-like permanent magnets is small and the magnetic body 12 is low, sufficient magnetic flux density cannot be obtained. On the other hand, if the number of plate-like permanent magnets is large and the height of the magnet body 12 is high, the size and weight of the permanent magnet unit 10 as a whole increases, and the structure becomes weak and the cost increases. There is a drawback. The number of plate-like permanent magnets is preferably 2 to 10 and more preferably 3 to 8.

FIG. 9 is a perspective view of the roof-shaped member 30 attached on the upper end surface 13 of the magnet body 12. As shown in FIG. 9, the roof-shaped member 30 includes a ridge line portion 3 1 at the top, and the upper surface of the ridge line portion 3 1 is a smooth curved surface. The upper surface of the ridgeline 3 1 can also be a flat surface. A bolt hole 3 4 for allowing the fastening port 20 to pass therethrough is formed in the center of the upper surface of the ridge part 3 1. In the port hole 3 4, a counterbore 3 4 A in which the head of the fastening port 20 is embedded is formed. Two slopes 3 2 and 3 3 extend diagonally downward from the ridge 3 1. The upper and lower surfaces of the slopes 3 2 and 3 3 are parallel rectangular planes.

The roof-shaped member 30 is made of a paramagnetic material such as soft iron. Here, the entire roof-shaped member 30 may be composed of one soft iron or the like, or a plurality of thin soft irons may be stacked. An electromagnetic steel plate may be used as the roof-shaped member 30.

Further, the roof-shaped member 30 is formed with an appropriate thickness. Roof-shaped member The thickness of 30 may or may not be uniform throughout. For example, the thickness near the ridgeline portion 31 may be reduced, and the thickness may be increased near the end away from the ridgeline portion 31. Alternatively, the thickness may be changed between one slope 3 2 and the other slope 3 3.

In the present embodiment, the angle 0 between the two slope portions 3 2 and 3 3 is 1600 °. Further, the angles 0 i and 0 ₂ between the slopes 3 2 and 3 3 of the roof-shaped member 30 and the axis of the magnet body 12 are the same, and 0 = 0 = ₂ = 80 °.

The angle 0 between the two slope portions 3 2 and 3 3 can be an angle other than 160 °. When the angle 0 is small, the distance between the ridgeline part 3 1 of the roof-shaped member 30 and the upper end face 1 3 of the magnet body 1 2 is increased, and is permanent with respect to the height of the magnet body 1 2. Magnet unit 10 Overall height increases. On the other hand, when the angle 0 is large, there is no big difference from connecting a flat soft iron to the upper end surface 13 of the magnet body 12. The angle 0 is preferably in the range of 90 ° to 1700 °, and 15 °. A range of ˜165 ° is more preferred.

The length of the ridge part 3 1 of the roof-shaped member 30 is L, and the distance between the lower ends of the two slope parts 3 2 and 3 3 is W. The roof-shaped member 30 may have a size that does not reach the outside in the radial direction of the upper end surface 1 3 of the magnet body 1 2 when the roof-shaped member 30 is placed on the magnet body 1 2 with the ridge line portion 3 1 facing up. However, it is preferable that the size extends to the outside. That is, the length L of the ridge part 3 1 may be smaller than the diameter D of the magnet body 12 (plate-like permanent magnets 12 A to 12 H), but is equal to or larger than the diameter D. I like it. The distance W between the lower ends of the two slope portions 3 2 and 3 3 may be smaller than the diameter D of the magnet body 12, but is preferably equal to or larger than the diameter D. In this way, almost all the magnetic lines of force that emerge from the upper end surface 13 of the magnet body 12 enter the roof-shaped member 30.

In the present embodiment, the ridgeline portion 3 1 and the two slope portions 3 2 and 3 3 are magnetized. Stone 1 Angle to tilt with respect to 2 axis 0! , θ ₂ are set to the same value. However, the two slopes 3 2 and 3 3 can be inclined at different angles (^ i ^^ G s). In the present embodiment, the roof-shaped member 30 is configured such that the two slope portions 3 2 and 3 3 extend obliquely downward from the ridge line portion 31, but is not limited thereto. For example, there may be only one slope portion, that is, a flat soft iron or the like may be placed on the upper end surface 13 of the magnet body 12 while being inclined. In addition, the roof-shaped member may be configured as follows.

FIG. 10 is a perspective view of a roof-shaped member 30 'according to another embodiment. The roof-shaped member 3 0 ′ is different from the roof-shaped member 30 in that the upper surfaces of the two slope portions 3 2 ′ and 3 3 ′ are not rectangular but substantially semicircular. Other points are the same as the roof-shaped member 30 of the embodiment shown in FIG. The length L ′ of the ridge part 3 1 ′ may be smaller than the diameter D of the magnet body 12, but is preferably equal to or larger than the diameter D. The distance W ′ between the lower ends of the two slope portions 3 2 ′ and 3 3 ′ may be smaller than the diameter D of the magnet body 12, but is preferably equal to or larger than the diameter D. The roof-shaped member 30 'of FIG. 10 also performs the same function as the roof-shaped member 30 of FIG.

The shape of the top surface of the roof-shaped member is not limited to a rectangle or a semicircle. FIG. 11 is a perspective view of a roof-shaped member 30 according to still another embodiment. The roof-shaped member 30 '' differs from the roof-shaped member 30 in that there is no ridgeline part and the inclined surface parts 3 2 ``, 3 3 '' are not flat but curved as a whole. The other points are the same as the roof-shaped member 30 of the embodiment shown in Fig. 9. The distance W '' between the lower ends of the slope portions 3 2, ', 3 3''is the same as that of the magnet body 1 2. It may be smaller than the diameter D, but is preferably equal to or larger than the diameter D. The distance W ′ ′ between the lower ends of the slopes 3 2 '' and 3 3 "and the length in the perpendicular direction The length L '' may be smaller than the diameter D of the magnet body 12, but it is equal to or equal to the diameter D. It is preferable to be larger. The roof-shaped member 3 0 ′ configured as shown in FIG. 11 also performs the same function as the roof-shaped member 30 shown in FIG.

Even when the roof-shaped members 3 0 ′ and 3 0 ′ are configured as shown in FIGS. 10 and 11, the slopes of the slopes 3 2 and 3 3 can be made different in the example of FIG. ₂ ) In the same way that the thickness is varied, the slope of the roof-shaped members 30 ', 30 is formed unevenly, or the thickness is unevenly formed. Also good.

With reference to FIGS. 6 and 7 again, the proximal end side yoke 16 attached to the lower end surface 15 of the magnet body 12 will be described. The illustrated base end side yoke 16 has a disk shape whose diameter is equal to or larger than the diameter D of the magnet body 12. The upper and lower surfaces of the proximal yoke 16 can also be square or rectangular. As shown in FIG. 7, a bolt hole 17 for receiving the distal end portion of the fastening port 20 is formed in the central portion of the proximal end side yoke 16, and the fastening hole is provided in the port hole 17. A female screw is formed to be screwed with the male screw at the tip of the G20. The proximal yoke 16 is made of a paramagnetic material such as soft iron.

Set the male screw of the proximal yoke 1 6 Screw in the female screw of the bolt hole 1 7. The roof-shaped member 30, the magnet body 12, and the base end side yoke 16 are integrally tightened and fixed to form a permanent magnet unit 10. Here, the outer peripheral part of the upper end surface 13 of the roof-shaped member 30 is fixed so that the part of the roof-shaped member 30 is in contact, but it is connected with the fastening bolt 20 so that it does not contact. You may do it. By using the fastening bolt 20 as the connecting means, the members constituting the permanent magnet unit 10 can be easily fixed.

Referring to FIGS. 1 and 2 again, the power generator 4 according to the first embodiment 4

The operation of 0 will be described.

As shown in Fig. 1, the first and second permanent magnets 5 1, 5 of the main rotor 44

In the initial state where the core 2 and the core 5 3 are opposed to each other, the motor 4

When the main rotor 4 4 is rotated by 2, the first and second permanent magnet units 5 1, 5 2 of the main rotor 4 4 come out of the force of the core 5 3 and the windings 5 4 a, 5 4 b The magnetic field generated in the surroundings changes, and induced currents are generated in the windings 5 4 a and 5 4 b by electromagnetic induction. At this time, due to the induced current, a magnetic force (magnetic field magnetic force) is generated in the ferromagnetic core 53 inside the windings 5 4 a and 5 4 b.

1st and 2nd permanent magnet units 5 1 and 5 2 force S core 5 3 <When the core 5 3 force is moved away, the induction generated in the windings 5 4 a and 5 4 b The direction of the current is different (Faraday's law). For this reason, each time the first and second permanent magnet units 5 1, 5 2 force S end 5 3 is passed along with the rotation of the main port 44, the winding 5 4 a , 5 4 b generates an electromotive force m, and an alternating current is generated. At this time, the magnetic force generated in the core 53 is also reversed alternately before and after passing through the first and second permanent magnet units 51 and 52. In addition, in one core 5 3 and the adjacent core 5 3, the winding directions of the wires 5 4 a and 5 4 b are the same, and the first and second permanents that are close to the core 5 3 This is different from the magnetic force tl K, which is generated from the magnet units 5 1 and 5 2. For this reason, the magnetic field magnetic poles generated in each core 53 are different from each other.

Thus, the magnetic field magnetic force generated on the core 53 side and the first and second permanent A repulsive magnetic force that produces a repulsive action and an attractive magnetic force that produces an attractive action are generated between the permanent magnet units 51 and 52. These two magnetic forces are divided into a positive torque (propulsive force) acting in the rotational direction of the main rotor 44 and a negative torque (electromagnetic brake) acting in the reverse direction.

For example, in a state immediately after the first and second permanent magnet units 51 and 52 have passed through the core 53, the first and second permanent magnet units 51 and 52 are moved in the rotational direction. When a repulsive magnetic force is received between the rear core 5 3 (the passed core 5 3), this acts as a positive torque. In this state,

1, the second Mizuishi stone unit 5 1, 5 2 also receives an attractive magnetic force with the next core 5 3 located in the j direction with respect to the rotation direction, so it acts as this attractive magnetic force plus norek Doing,

On the contrary, the first and second permanent magnet units 5 1 and 5 2 are in the state immediately before passing through the S core 53 and the first and second permanent magnet units 5 1 and 5 2 When it receives a repulsive magnetic force with the core 5 3 in front of it, it works as a negative torque. In this state, the first and second permanent magnet units 5 1 and 5 2 also receive an attractive magnetic force with the passed core 5 3 at the rear with respect to the rotation direction. Acts as

Immediately after starting to rotate the main rotor 44, the rotation speed of the main rotor 44 is slow, and the first and second permanent magnet units 5 1, 5 2 and 5 3 of the main port 4 4 In other words, the first and second permanent magnet units 5 1 and 5 2 of the main rotor 4 4 approach the core 53 and pass through the position where the most repulsive force is strong. Since the rotation resistance of the main rotor 44 is large, a relatively large rotational torque from the motor 42 is required to rotate the main rotor 44.

Driven by motor 4 2 over time after starting main rotor 4 4 The rotational speed of the main port 44 is gradually increased by the force and the positive torque received by the magnetic field generated between the first and second permanent magnet units 5 1, 5 2 and 5 3. As it speeds up, the main rotor 4 4 gains a relatively large inertial force. Due to this inertial force and the positive torque received by the magnetic force between the first and second permanent magnet units 5 1, 5 2 and the core 5 3, the main unit 44 4 is large. After obtaining propulsive force, it will eventually rotate at a constant speed. In the constant speed rotation state, the rotational torque required to rotate the main motor 44 becomes smaller and stable. As a result, the power consumption of the motor 42 decreases.

However, if the roof-shaped member 30 is removed from the first and second permanent magnet units 51 and 52 of the main rotor 44 and the main unit 44 is to be rotated. When the first and second permanent magnet units 5 1 5 2 approach the core 5 3, the repulsive force is strong, and a very strong force is required to turn the main rotor 4 4. On the other hand, in the state shown in Fig. 1 in which the roof-shaped member 30 is attached to the first and second permanent magnets 卜 51, 52, the main rotor 44 is rotated with a weaker force. be able to.

In addition, the power generator 40 according to the present embodiment has a strong assist against the main rotor 44 because the first and second permanent magnet units 5 1, 52 are provided with the roof-shaped member 30. Along with being able to obtain toka, a permanent magnet unit 卜 5

When 1 and 5 2 approach core 5 3, the repulsive force is weakened. Therefore, the power generation efficiency is high, and a large power generation can be obtained with a relatively small driving force. The central axis of the permanent magnet units 5 1 and 5 2 should be in the radial direction of the power generator 40. Can be attached. The structure of the mouthpiece and main mouthpiece 44 is simple and easy to manufacture.

Furthermore, when using the roof-shaped member 30 '' configured as shown in Fig. 11, when the first and second permanent magnet units 5 1 and 5 2 approach the core 5 3. The action of the lines of magnetic force received and the first and second permanent magnets 卜 5 1 and 5 2 are the core. Switching to the action of the lines of magnetic force received when approaching 5 3 is performed smoothly, so that rotational torque can be transmitted more smoothly.

The permanent magnet units 5 1, 5 used in the power generator 40 of this embodiment are used.

2 of the roof-shaped member 30 (30 ', 30 ") has its slopes 3 2, 3 3 symmetric with respect to the central axis of the magnet body 12, but For example, the slopes 3 2 and 3 3 may have different slopes.

(θ ₁ ≠ Θ ₂ ), thickness can be different o

In this way, the first and second permanent magnet units 5 1 of the main rotor 4 4

, 5 2 and magnetic field lines acting when approaching core 5 3, and first and second permanent magnet units 5 1, 5 2 force When approaching core 5 3 to 3S after approaching core 5 3 The acting magnetic field lines are different from each other. As a result, when the first and second permanent magnet units 5 1 and 5 2 approach the core 53, the repulsive force is small and it can approach more easily, and the first and second permanent magnet units卜 5 1,

When the 5 2 moves away from the core 5 3, the main port 4 4 can obtain a greater driving force.

In addition, each of the above-described embodiments is merely an example of the embodiment for carrying out the present invention, and the technical scope of the present invention should not be construed as being limited thereby. is there.
