Abstract

PURPOSE:To obtain a motor requiring no power supply by fitting a magnet to an arm mounted on a rotor and oppositely facing the magnet and a stator magnet. CONSTITUTION:A shaft 3 is installed to a rotor 2, and an arm 4 in an arbitrary shape is set up on the side surface of the rotor 2. A magnet 5 is fitted to the side surface of the arm 4. The magnet 5 attached to the arm 4 and a stator magnet 1 are faced oppositely. The arm 4 is mounted on the side surface of the rotor 2, and repulsive force working to the magnet 5 is applied to the rotor 2 through the arm 4. That is, the arm 4 is set up, thus displacing the direction of force directed toward the center of the rotor 2 working to the magnet 5, then generating force through which the rotor 2 is turned.

Description

Detailed Description of the Invention (Industrial Application Field) This invention provides a magnet 5 to an arm 4 of an arbitrary shape provided on a rotor 2, and a magnet 5 is provided on an arm 4 of an arbitrary shape provided on a rotor 2. The present invention relates to a motor using a magnet, in which a magnet 1 is arranged.

(Problem to be solved by the invention) Conventionally, 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 obviates these drawbacks.

There was also a demand for the development of a motor that did not require a power source.

(Means and effects for solving the problem) This will be explained with reference to the drawings: (A) A rotating shaft 3 is provided to the rotor 2.

(B) Arm 4 of arbitrary shape (hereinafter referred to as arm 4)
is provided on the side of the rotor 2.

(C) A magnet 5 is provided on the side surface of the arm 4.

(D) The stator magnet 1n polarity facing the magnet 5 provided on the arm 4 is magnetized so that the stator magnet 1n surface facing the magnet 5 has one polarity, and the stator magnet 1n facing the magnet 5 is magnetized. Place magnet 1.

The present invention has the above-described configuration, and if the stator magnet 1 (hereinafter referred to as magnet 1) and the magnet 5 have the same polarity and face each other, the repulsive force acting on the magnet 5 is originally directed toward the center of the rotor 2. This is a force in the direction toward , and no force to turn the rotor 2 is generated at all.

However, the rotor 2 of the present invention is provided with an arm 4 on the side, and the repulsive force acting on the magnet 5 is applied to the rotor 2 through the arm 4.

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, thereby generating a force that turns the rotor 2.

Furthermore, if one of the magnets 1 and 5 faces each other with opposite polarity, the attractive force acting on the magnet 5 will be deviated from the direction outward from the center of the rotor 2, and the direction of rotation will be changed. change.

In this case, even if the magnet 5 is made of a magnetic material, an attractive force is generated in the same way, so the magnet 5 rotates.

(Claim 5) Furthermore, even if the arm 4 and the magnet 5 are made of magnetic material and the arm 4 and the magnet 5 are integrally molded, if the arm 4 faces the magnet 1, an attractive force will be generated and the magnet will rotate. do. (Claim 5) In this way, the present invention provides the magnet 5 by the arm 4.
This is characterized in that the force that rotates the rotor 2 is generated by shifting the direction of the force acting on the rotor 2 from the diameter line of the rotor 2.

Furthermore, it goes without saying that the rotational force will change if the following procedure is carried out.

(E) Change the facing angle of magnet 1 and magnet 5.

(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 the magnet 1n.

The magnetic force of the magnet 5 is changed.

(L) Center point of the mounting surface of rotor 2 of arm 4 and rotor 2
0°≦KD≦360°, 0°≦KD≦−360° Angle K that changes the angle KD of the center point of the tip of arm 4 with respect to the line connecting the center points of
When D is 0 degrees, the magnet 5 is provided on the arm 6 as shown in FIG. 2, and the direction of the force acting on the magnet 5 is shifted from the diameter line of the rotor 2 depending on the position where the magnet 5 is provided.

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

Incidentally, even if the magnet 1 is placed inside the magnet 5 and the magnet 5 is provided on the arm 4 so as to face the magnet 1, as in conventional electric motors, the force acting on the magnet 5 is not caused by the rotation by the arm 4. Since it deviates from the diameter line of child 2, it rotates in the same way. (Outer rotor type motor) This outer rotor type motor is applicable to claims 1 to 5.

(Effects of the Invention) As described above, since the motor using the magnet of the present invention uses magnets for both the stator pole and the rotor pole, it does not require a power source and can be used as a light bulb even without batteries. It can be used even if the line is not drawn.

It is economical as it does not require batteries or electricity.

(Embodiment) (N) Even if the arm 4 is a magnet and the arm 4 and the magnet 5 are integrally molded, the arm 4 shifts the attractive force or the repulsive force from the diameter line of the rotor 2.
If the 1n surfaces of the magnet face each other, they will rotate in the same way.

(Claim 4) (O) The arm 4 provided to the rotor 2 is not limited to being screwed, and may be welded.

It may also be anything else.

Incidentally, if the rotor 2 and the arm 4 are integrally molded, assembly becomes easier.

It may be provided on the top or bottom surface. It may also be anything else.

(Q) It is best to use a non-magnetic material for the rotor 2.

However, as long as there is a sufficient distance between the magnet 1 and the rotor 2, there is no problem even if the rotor 2 is made of a magnetic material.

It may also be a hexahedron.

Alternatively, it may be a thin circular plate.

It may also be anything else.

(T) The shape of the magnet 1n is not limited to a prismatic ring shape, but may be an elliptical arch shape. Alternatively, they may be arranged around a regular hexahedron. Also, other types may be used.

Incidentally, when the number of poles of the rotor 2 increases, the magnets 1 are not limited to being arranged over the entire 360 degrees, but may be arranged partially. Also, other types may be used.
