The central magnet plate has a width narrower than those of the magnetic plates at both sides so that the poles are disposed adjacent in reverse direction. The drawing shows N, S, N at the upside and S, N, S at the downside. A bearing 4 which supports a shaft 5 is provided at the center of the central magnetic plate. A plurality of arms 6 are formed at the shaft 5, and a magnet 8 is mounted at the end and a rotor 7 on which a coil 9 for neutralizing the magnetic force of the magnet 8 by the current is mounted is mounted so that the poles are directed toward the rotating direction.

A prime mover which has highly rotating efficiency can be constructed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic prime mover, and more particularly to a magnetic prime mover that can obtain efficient rotational motion by utilizing the repulsive force between like-pole permanent magnets.

The operating principle of the present invention is that when a permanent magnet is brought close to a magnetic plate formed to have an N pole on the upper surface and an S pole on the lower surface so that its magnetic direction is parallel to the magnetic plate, then Attach this permanent magnet to the shaft via an arm to convert the horizontal force due to the magnetic force acting on the magnet into rotational force, and use this rotational force to rotate the shaft to obtain a rotational driving force. That is. However, when the permanent magnet reaches the edge of the magnetic plate, the horizontal force due to the magnetic force disappears due to the difference in the distribution of magnetic lines of force on the magnetic plate, and conversely, a force trying to attract the permanent magnet acts on the edge of the magnetic plate. This has the disadvantage that the existing rotational inertia force is canceled out and the horizontal movement is stopped. Therefore, when a permanent magnet is located at the edge of the magnetic body, the magnetic force of the permanent magnet is neutralized by energizing an electromagnetic coil formed at the periphery of the permanent magnet, or the rotational inertia is reduced by changing the polarity. The permanent magnet is made to rotate on the magnet plate by obtaining an intermittent rotational force without canceling out the force.

That is, the gist is that a flat magnetic plate having poles on the upper and lower surfaces is provided, and three of these magnetic plates are positioned horizontally with their poles vertically and connected and held with their polarities reversed to generate magnetic force. The central magnet plate of this magnetic plate is formed to be narrower than the magnet plates on both sides, and a shaft hole is formed in the center of the central magnetic plate to pass through in the vertical direction. A shaft is supported in the shaft hole, and a rotor is fixed to this shaft via an arm.The rotor consists of a permanent magnet and an electromagnetic coil that neutralizes the magnetic force of the permanent magnet. It is attached to the arm so that its poles are at the front and back positions in the rotating direction of the rotor, and when the rotor is positioned against the central magnet plate, the electromagnetic coil is energized to neutralize the magnetic force of the rotor,
The reason lies in the fact that the shaft of this rotor is used as the output shaft.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a magnet plate having an N pole N on the upper surface and an S pole S on the lower surface. The magnet plate 1 is made of a synthetic resin magnet plate made by mixing magnet powder into a synthetic resin, and a plurality of synthetic resin magnet plates are stacked together to produce a strong magnetic force.

Three magnet plates 1 formed in this manner are provided, and these magnet plates 1 are connected and held with their poles positioned horizontally and in the vertical direction, and their polarities are reversed to form a magnetic plate 2.

The center magnet plate 1 is formed to be narrower than the other two measuring section magnet plates 1, and a shaft hole 3 is formed in the center of the center magnet board 1 to pass through in the vertical direction. A bearing 4 made of a synthetic resin bushing or the like is disposed on the shaft 5, and the shaft 5 is pivotally supported on the central magnet plate 1 via the bearing 4.

A rotor 7 is disposed on the shaft 5 via an arm 6. The rotor 7 consists of a substantially cylindrical permanent magnet body 8 and an electromagnetic coil 9 that neutralizes the magnetic force of the permanent magnet body 8, and the poles of the rotor 7 are located at front and rear positions in the rotation direction of the rotor 7. It is attached to the arm 6 like this.

In the illustrated example, three rotors 7 are arranged at 120" intervals around the shaft 5, but the number is not particularly limited. Note that by arranging a large number of rotors 7, More powerful rotational force can be obtained.

Further, the shaft 5 is provided with a commutator 10 for energizing the electromagnetic coil 9.
The commutator 10 has the ten poles of the DC power supply 12, -
When the brushes 11 connected to the poles are brought into elastic contact and the rotor 7 is positioned on the central magnet plate 1, the magnetic force of the permanent magnet body 8 of the rotor 7 is applied to the electromagnetic coil 9. It is designed to be neutralized by magnetic force.

The electromagnetic coil 9 is energized by the commutator 10 and the brush 1.
1, a contact plate is formed near both side edges of the central magnet plate 1, and a brush (both not shown) that elastically slides into contact with the contact plate is provided. When the rotor 7 is positioned on the magnet plate 1, the electromagnetic coil 9 may be energized so as to neutralize the magnetic force of the magnet body 8 of the rotor 7.

The present invention is constructed as described above, and is provided with a flat magnet plate 1 having poles on the upper and lower surfaces, and three of these magnet plates 1 are positioned laterally with their poles in the upper and lower directions, and the magnet plates 1 are arranged horizontally with their poles in the vertical direction. The magnetic plate 2 is constructed by connecting and holding the magnetic plate 2 with the polarities reversed, and the central magnetic plate 1 of the magnetic plate 2 is narrower than the magnetic plates 1 on both sides. A penetrating shaft hole 3 is formed, and a shaft 5 is inserted into the shaft hole 3 of the central magnet plate 1.
A rotor 7 is fixed to this shaft 5 via an arm 6, and the rotor 7 consists of a permanent magnet body 8 and an electromagnetic coil 9 that neutralizes the magnetic force of this permanent magnet body 8. Since the child 7 is attached to the arm 6 so that its poles are at the front and rear positions in the rotating direction of the rotor 7, the rotor 7 receives a rotation component on the magnetic plate 2 due to the repulsive force between the same poles of the permanent magnets, and the magnetic force is Both measuring parts of the plate 2 can be rotated on the magnet plate 1 about the axis 5.

In addition, the central magnet plate 1, which is arranged with opposite polarity to the other measuring part magnet plates 1, is formed with a narrow width. Since the electromagnetic coil 9 is energized to neutralize the magnetic force of This allows the rotor 7 to continue rotating.

Therefore, a magnetic motor with a shaft 5 to which the rotor 7 is fixed as an output shaft can be provided with a simple configuration, and moreover, the repulsive force of the permanent magnet can be efficiently used, and its power consumption is low. This makes it possible to achieve extremely high rotational efficiency.

In the embodiment, there is one magnetic plate 2, and the rotor 7 is rotated on this magnetic plate 2. However, the present invention is not limited to this, and a plurality of magnetic plates 2 may be provided. The magnetic plates 2 are arranged side by side at regular intervals so that the opposing polarities of the magnetic plates 2 are the same, and the rotor 7 is arranged between the magnetic plates 2 via the respective arms 6. You may do so. With such a configuration, it is possible to further increase the rotational force.

As explained above, according to the present invention, a magnetic prime mover with high rotational efficiency can be provided by utilizing the repulsive force caused by the same polarity of permanent magnets and by efficiently energizing the electromagnetic coil. This is an invention that has extremely excellent effects.
