Abstract

PURPOSE:To eliminate a power source of a motor by providing a nonmagnetic arm on the side of a rotor, and providing a magnet on the side of the arm. CONSTITUTION:A rotor 2 is provided on a rotational shaft 3, and a nonmagnetic arm 4 of an arbitrary shape is formed on the side. A stator magnet 1 is disposed on the periphery of the rotor 2. A magnet 5 is provided on the side of the arm 4, and opposed at the same pole to the magnet 1. Thus, since the repelling force acting on the magnet 5 of the arm is applied through the arm 4, the rotor 2 generates a force for rotating the rotor 2 by displacing the direction of the force directed to the center of the rotor 2.

Description

DETAILED DESCRIPTION OF THE INVENTION In the present invention, a magnet 5 is provided on a non-magnetic arm 4 provided on a rotor 2, so that the magnet 5 and the stator magnet 1 face each other.
The present invention relates to a motor using magnets in which a stator magnet 1 is arranged.

Traditionally, motors require a power source, and the battery may run out or
It could not be used in areas without power lines.

The present invention has been devised to eliminate these drawbacks, and will be explained with reference to the drawings. (A) A rotating shaft 3 is provided at the center of the rotor 2.

(B) A non-magnetic arm 4 of an arbitrary shape is provided on the side surface of the rotor 2.

(C) Magnet 5 attached to the side of the non-magnetic arm 4 provided on the rotor.
will be established.

(D) Magnetize the stator magnet 1 facing the magnet 5 provided on the non-magnetic arm 4 so that the surface of the stator magnet 1 facing the magnet 5 has the same magnetism, and so that it faces the magnet 5. A stator magnet 1 is arranged.

The present invention has the above configuration, and if the stator magnet 1 and the magnet 5 have the same magnetism and face each other, the repulsive force acting on the magnet 5 is originally a force directed toward the center of the rotor 2, In this case, no force is generated to turn the rotor 2.

However, the rotor 2 of the present invention has a non-magnetic arm 4 (hereinafter referred to as arm 4) of an arbitrary shape on the side surface, and the repulsive force acting on the magnet 5 is applied to the rotor 2 through the arm 4. be.

That is, by providing the arm 4, the direction of the force acting on the magnet 5 toward the center of the rotor 2 is shifted, and the force acting on the magnet 5 is shifted toward the center of the rotor 2.
It generates the force that turns the .

Furthermore, if either the stator magnet 1 or the magnet 5 has opposite magnetism and faces each other, the attractive force acting on the magnet 5 will be deviated from the direction outward from the center of the rotor 2, causing rotation. The direction changes.

In this case, even if the magnet 5 is replaced with a magnetic material, the same attractive force will be generated and the magnet will rotate.

Further, even if the arm 4 is made of a magnetic material, if it faces the stator magnet 1, an attractive force will be generated and the arm will rotate.

As described above, the present invention is characterized in that a force for rotating the rotor 2 is generated by shifting the direction of the force acting on the magnet 5 by the arm 4 from the diameter line of the rotor 2.

In addition, the same result can be obtained by alternately providing arm 4 with arms that are oriented 180 degrees to arm 4 on the side of rotor 2, and alternately providing N-pole and S-pole magnets to the two types of arms. It is possible to rotate the

In this case, when the magnetism of the magnet in arm 4 is N pole, the magnetism of the magnet in am, which is oriented 180 degrees with respect to arm 4, is S.
The type of arm and magnetism, such as the poles, must match.

Also, the following (E), (F), (G), (H), (I),
It goes without saying that the rotational force will change if (J), (K), (L), and (M) are implemented.

(E) Change the angle at which stator magnet 1 and magnet 5 face each other.

(F) Increase the number of poles of the rotor 2.

(G) Change the length of arm 4.

(H) The rotor 2 is made hollow.

(I) Arm 4 is hollow.

(J) Change the position of the magnet 5 provided on the arm 4.

(K) Change the magnetic force of stator magnet 1 and magnet 5.

(L) The center point of the bonding surface between arm 4 and rotor 2 and rotor 2
The angle Z of the center point of the tip of arm 4 with respect to the line connecting the center points of is changed.

0°≦Z≦360° When the angle Z is 0° and 360°, as shown in Fig. 2, the magnet 5 is provided on the arm 6, and depending on the position where the magnet 5 is provided, the direction of the force acting on the magnet 5 toward the center is determined. is shifted from the diameter line of the rotor 2.

(M) Change the length from the adhesive surface of rotor 2 and arm 4 to the center of rotor 2.

In this way, the motor using magnets of the present invention uses magnets for both the stator pole and the rotor pole, so it does not require a power source and can be used even without batteries or without a power line. You can also use

It is economical as there is no need for electricity or batteries.

Note that even if the stator magnet 1 is placed inside the magnet 5 and the magnet 5 is provided on the arm so as to face the stator magnet 1, as in conventional electric motors, the force acting on the magnet 5 will be the same. are shifted from the diameter line of the rotor 2 by the arm, so they rotate in the same way.

Further, the motor using magnets according to the present invention may be implemented as follows.

(N) Even if the arm 4 itself is a magnet, the attractive force or repulsive force is shifted from the diameter line of the rotor 2 depending on the inclination of the arm 4, so the north pole face or the south pole face of the arm 4 is fixed. Arm 4 faces child magnet 1.
If you magnetize it, it will rotate in the same way.

(O) The arm 4 provided to the rotor 2 can be screwed, glued,
Other materials may be used, but if they are integrally molded, assembly will be easier.

(P) The arm 4 provided on the side surface of the rotor 2 is not limited to the side surface of the rotor 2, but may be provided on the upper surface or the lower surface, or may be provided on a combination of these three surfaces.

(Q) The rotor 2 may be made of magnetic material within the following range.

Force acting on magnet 5 > Force acting on rotor 2 (R) The shape of the rotor 2 is not limited to a cylindrical shape,
It may be hexahedral or other shapes.

(S) The shape of the arm 4 is not limited to the L-shape;
It may be arcuate or other shapes may be used.

(T) The shape of the stator magnet 1 is not limited to a circle, and may be semicircular or other shapes.

Note that when the number of poles of the rotor 2 increases, it is not necessary to arrange the stator magnets 1 over the entire 360 degrees, but they may be arranged partially.

(U) The shape of the magnet 5 is not limited to an arcuate rectangular parallelepiped, and may be a regular hexahedron or other shapes.

(V) The magnet 5 is not limited to the side of the arm 4,
It may be provided at the tip, or it may be provided on a combination of these two surfaces.

(W) The magnet 5 provided on the arm 4 may be provided by providing a recessed portion in the arm 4 and providing the magnet 5 there.
