Abstract

PROBLEM TO BE SOLVED: To realize a magnet motor which is driven by the attraction and repulsion of magnets and requires smaller external force rotating force obtained to change the polarities of magnets. SOLUTION: This motor is constituted of definite positional magnets 2 whose polarities can be changed and which are fixed at the opposite ends of a rotary body 1 symmetrically distant with respect to the center 0 of rotation of the rotary body 1, and a heavy-weight body 4 which is provided at both ends with fixed permanent magnets 3 and which, passing through the center of rotation of the rotary body 1, freely moves in a space between the positions in a specified distance X away from the positional magnets located at the opposite ends of the rotary body 1. Rotating force is generated by the decentering of the center of gravity of the heavy-weight body due to the movement of it. In order to move the heavy-weight body 4, the magnets located at a lower position of rotation are repelled by each other and, at the same time, the magnets located in an upper position of rotation are attracted by each other. By this method, the heavy-weight body which is nearly double the external force necessary for changing the polarities of the magnets located in the lower position of rotation can be displaced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnet motor for driving a rotating body by utilizing the attraction and repulsion of a magnet.

[0002]

2. Description of the Related Art Conventionally, various attempts have been made to obtain motive power by utilizing the attraction and repulsion of a magnet. However, all of them have proposed an external force required for driving such as switching the polarity of a magnet. However, since it was equal to or higher than the obtained output, it was impossible to realize.

[0003]

In view of the fact that none of the conventionally proposed magnet motors can be realized, the present invention provides an external force energy required for switching the polarity of a magnet for rotational driving. An object of the present invention is to provide a structure of a magnet motor which is smaller than the rotational energy obtained and can be realized.

[0004]

According to the present invention, there are provided fixed position magnets 2 and 2 which are arranged at opposing positions separated by a predetermined distance from a rotation center O of a rotating body 1 and have permanent magnets 3 at both ends.
3 and a weight body 4 that passes through the center of rotation O and floats between the fixed-position magnets 2 and 2 at a position separated by a certain distance X from the fixed-position magnets 2 at the opposite position.

The idle distance L of the weight body 4 having the permanent magnets fixed at both ends is equal to the permanent magnet 3 fixed to one end of the weight body 4.
The distance is approximately twice the distance that can be repelled or attracted in the vertical direction by the opposed fixed position magnet 2. Then, at the position where the weight body is vertically oriented, the polarity of the fixed magnet at the lower position is changed to be the same as the permanent magnet of the opposed weight body, and the polarity of the fixed magnet at the upper position is opposed. Make the polarity of the permanent magnet of the weight body different. As a result, the weight body is moved upward, and a driving force is generated in the rotation body by the movement of the center of gravity of the rotation body accompanying the movement of the weight body.

One effective means for changing a set of magnets in the attracted state to the repelled state is to move one magnet in a direction crossing the line of magnetic force. Specifically, a holder 5 rotatable on a tangential plane of the rotation trajectory of the rotating body is supported on the outer periphery of the rotating body 1, and two or more fixed-position magnets 2 are mounted on the same plane. The guides 6 are arranged with different polarities, and the guide 6 arranged on the outer periphery of the rotating body is engaged with a part of the holder 5, and the holder is rotated according to the rotating position of the rotating body, and the permanent magnet 3 of the heavy body is Opposing fixed position magnet 2
To change the polarity of the home position magnet. The change of the magnetic pole is performed at the lower position of the rotation. The auxiliary magnet 7 can be fixed by approaching the fixed position magnet 2 to the outside of the fixed position magnet 2 of the rotating body 1 to apply a repulsive force to the attracted magnet.

[0007]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view showing a basic mode of the present invention. The rotating body 1 formed in a single cylindrical shape rotates about a rotation center O, and has an output shaft fixed with the rotation center O as an axis.

The fixed magnets 2, 2 whose polarity can be changed are arranged at opposing positions separated by a certain distance from the rotation center O of the rotating body 1, that is, at both ends, and move freely inside the cylindrical rotating body 1. Stores possible weights 4. The weight body 4 is
Weights 4b are attached to both ends of the rod-shaped support 4a, and permanent magnets 3 and 3 are fixed to the ends thereof.
Approach the fixed position magnet 2 to a position separated by a certain dimension X, and allow the range of the stroke L to float.

The attractive force of the two magnets is inversely proportional to the square of the distance. Therefore, when the two magnets come into close contact with each other, the coercive force becomes very large, and an excessive force is required to separate the two magnets in the attracted state. Therefore, in the present invention, the closest approach distance between the heavy permanent magnet and the fixed position magnet is secured to some extent so that an excessive force is not required. In order to prevent the weight body 4 from approaching the fixed position magnet 2 up to a position separated by a certain dimension X, and not to approach it further, a stopper 8 is projected inside the cylindrical rotating body 1. The permanent magnets 3 fixed to both ends of the weight body 4 have the same polarity, and in the illustrated example, the outside has N poles.

When the rotating body 1 is oriented in the vertical direction and shown by a solid line in FIG.
Is an S pole and attracts the permanent magnet 3 of the weight 4. On the other hand, the surface of the fixed position magnet 2 at the lower position facing the weight body 4 is an N pole, and repels the permanent magnet 3 of the weight body 4. As a result, the weight 4 is pushed upward. As a result of the weight body 4 being pushed upward, the center of gravity O _{1 of the} weight body is located at 1/2 L above the center of rotation O, and the eccentricity generates a rotational force on the rotary body 1 and is indicated by an arrow. Start to rotate.

The rotating body 1 makes a half turn and the fixed position magnet 2
When the portion where the permanent magnet 3 of the weight body is in the attracted state comes to the lower position, the center of gravity of the weight body is located at O ₁ ′ immediately below the rotation center O, and the rotational force is lost. At this time, if the polarity of the fixed position magnet 2 located at the lower position is changed to the polarity repelling the permanent magnet 3 of the weight body 4, in the illustrated example, the surface facing the weight body is changed from S pole to N pole, the weight body 4 To a state shown by a solid line from a state shown by a two-dot chain line in FIG.
A rotational force due to eccentricity is generated again.

The combination of the magnetic force of the permanent magnet 3 of the weight body 4 and the magnetic force of the fixed position magnet 2 is such that one fixed position magnet 2 and one permanent magnet 3
Thereby, the weight body 4 is made a magnet having a strength capable of pushing up or pulling up about 1/2 L. That is, the weight L can be moved by repelling the weight 4 approximately from the bottom and by sucking the weight 4 approximately 1/2 L from the top. According to the experiment of the present inventor, a displacement slightly larger than twice the distance for sucking or repelling the weight body was actually realized by the synergistic action of the suction force and the repulsion force.

It is a known fact that the attractive force and the repulsive force of the magnet are inversely proportional to the square of the distance, and the closer the force, the stronger the force. As shown by the solid line in FIG. 1, once the weight body rises and the fixed position magnet 2 and the permanent magnet 3 at the upper position are attracted, the weight body 4 can be held only by the attraction force at the upper position. The repulsive force of the fixed position magnet 2 and the permanent magnet 3 at the lower position is not necessary. That is, the fixed position magnet 2 and the permanent magnet 3 from the upper position to the lower position of the rotating body 1 are in the attracted state, and the repulsive force is obtained by forcibly changing the polarity at the lower position. The fixed position magnet 2 and the permanent magnet 3 from the lower position to the upper position of the body 1 do not need to be maintained in a repulsive state, and need to be changed to the attracted state before moving to the upper position. There is. Then, after the weight body 4 is lifted by forcibly changing the polarity of the fixed-position magnet 2 in the lower position, the fixed-position magnet 2 is set in a free state. ,
By the permanent magnet 3, a force for changing the polarity of the attracted state acts, and the polarity is naturally changed. That is,
By forcefully acting on the fixed position magnet 2 at the lower position, the weight 4
By a small external force that raises
The weight body 4 can be raised by a large distance L, and a large output can be obtained by the large lifting distance L.

Although it is possible to use an electromagnet as the fixed position magnet 2 and change the polarity of the magnet by switching the current direction, it is preferable to use a permanent magnet. FIG. 3 illustrates a specific method of changing the polarity of the permanent magnet 3 of the weight body and the fixed position magnet 2 in the attracted state. In this embodiment, the holder 5 is supported by the support shaft 9 with respect to the rotating body so as to rotate on the tangential plane of the rotation locus at the outer peripheral portion of the rotating body.
, And two fixed position magnets 2 and 2 are arranged on the holder 5. The two fixed-position magnets 2, 2 support the support shaft 9
Are arranged on the surface of the holder 5 that rotates about the rotation axis on the rotation locus facing the permanent magnet 3 of the rotating body 1 with different polarities.

To rotate the holder 5 to change the polarity of the fixed-position magnet 2 directly facing the heavy permanent magnet 3,
The guide 6 is arranged on the outer periphery of the rotating body, and the guide roller 10 of the holder 5 is engaged with the guide groove 6a to follow the amplitude in the width direction of the guide groove 6a. The fixed position magnet 2 can be changed. The force required to change the attracting magnet into a repelling magnet acts as a resistance to the rotation of the holder 5, and this force corresponds to a force that pushes the weight 4 up to a height of 1 / 2L.

FIG. 4 is a sectional view of an example in which the auxiliary magnet 7 is provided outside the holder 5 on which the fixed position magnets 2 and 2 are mounted, that is, outside the fixed position magnet 2 by extending the rotating body 1. The state of the upper position of rotation of a rotating body is shown. At this time, the heavy permanent magnet 3 and the fixed position magnet 2 mounted on the holder 5 are in the attracted state, and the auxiliary magnet 7 fixed to the outermost of the rotating body
Is fixed to a polarity that repels the fixed position magnet 2 mounted on the holder 5. Therefore, by the balance between the force attracted by the heavy permanent magnet 3 and the force repelled by the auxiliary magnet 7, the holder 5 will stop the fixed position magnet 2 with the permanent magnet 3 at either the attracted state or the repelled state. And

When the repulsive force of the auxiliary magnet 7 and the fixed position magnet 2 is smaller than the attractive force of the permanent magnet 3 and the fixed position magnet 2,
While maintaining the state of FIG. 4, at the lower position of the rotation of the rotating body,
It functions as an auxiliary force when rotating the holder 5, and functions so that the holder can be rotated with a smaller force. When the repulsive force between the auxiliary magnet 7 and the fixed position magnet 2 is larger than the attraction force between the permanent magnet 3 and the fixed position magnet 2, a holding force is required by a guide or the like to maintain the state of FIG. However, in the lower position of the rotation of the rotating body, the holder 5 holds the fixed position magnet 2 with the heavy permanent magnet 3.
Automatically rotates to the position where it is repelled.

FIG. 2 shows a cylinder 1 passing through a rotation center O.
It is a longitudinal cross-sectional view showing a form in which four weight bodies are combined with a rotating body 1 in which a and 1a project radially in all directions. If one of the weights in the form shown in FIG. 2 is captured, it is of the above-described basic form. However, in the embodiment in which a plurality of weight bodies are combined as shown in FIG. 2, it is necessary to allow each of the weight bodies to move freely. Displace in the direction.
In the case of a rotating body having a single weight, a dead point is generated at the rotational position. However, in the case of a form in which a plurality of weights are combined as shown in FIG. 2, smooth driving is always possible because a rotating force is always generated.

[0019]

According to the first aspect of the present invention, the position of the weight body in the rotating body is moved by utilizing the attraction and repulsion properties of the magnet, and the eccentricity accompanying the movement of the weight body is achieved. Thus, a rotating force can be generated in the rotating body. At this time, the weight body is repelled from below the vertical position and is sucked from above. The external force energy required to change the polarity of the fixed-position magnet in this state is the force required to raise the weight by half, so that the rotating body generates rotational energy. become.

According to the second aspect of the present invention, the polarity of the permanent magnet fixed to the weight that moves in the direction intersecting with the axis of the rotating body and the fixed position magnet that performs attraction and repulsion are smoothly changed. be able to.

According to the third aspect of the present invention, in the second aspect of the invention, when the polarity of the fixed position magnet is changed, the repulsive force of the permanent magnet of the weight body and the fixed position magnet and the attraction by the magnetic force of the auxiliary magnet. The forces cancel each other out, and the polarity change of the home position magnet can be performed with a smaller force.
