JPS62178155A - Unwound motor using repulsion of permanent magnet - Google Patents

Abstract

PURPOSE:To obtain a stable turning force by using a repulsion of permanent magnets arranged on a small rotating disc driven by a micromotor and that of permanent magnets arranged on a rotating disc to be the main body of a motor rotor. CONSTITUTION:A micromotor 1 is driven by a dry cell 2 to rotate a small disc 3 connected directly with said micromotor. On this small disc 3, several permanent magnets 4 are arranged symmetrically. Also on the disc 5 to be a motor rotor, several permanent magnets 6 are arranged symmetrically. The repulsion of said permanent magnets 4 and 6 rotates the disc 5 so that a turning force may be extracted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses permanent magnets arranged symmetrically on a rotating small disk driven by a micro motor.

On the other hand, this relates to a motor that does not use windings and is rotated by the repulsive force of permanent magnets arranged symmetrically on a large disk serving as a motor rotor having a diameter several times larger than that of the motor rotor.

Conventionally, a motor has a stator or a rotor wound with wires, and rotational force is obtained by passing an electric current through the motor.

Therefore, when used outdoors, there is a problem in terms of power supply, and in the current situation where small and large capacity batteries have not been sufficiently developed, the use of motors has been very inconvenient. Furthermore, the presence of windings makes the motor structurally complex, which is also undesirable from a cost standpoint.

The present invention was made to compensate for such shortcomings.1
Please explain the outline using drawings.

(a) The micro motor (1) is driven by a dry battery (2), and a small circular plate (3) directly connected to this micro motor rotates. Here, a permanent magnet (4) is placed on this rotating small disk.
are arranged symmetrically.

(b) As shown in Figure 1, a disk (5) several times the diameter of which will become the rotor of the motor is installed on almost the same surface as this small rotating disk, and a permanent magnet (6) is also placed on this disk. ) are arranged symmetrically.

(c) The repulsive force between the permanent magnet (4) and the permanent magnet (6) is strong when the disc (3) and the disc (5) have the same polarity and are in opposing positions during rotation. The rotational force becomes large.

) To increase the rotational force, three small discs (3) were installed as shown in Figure 1. It depends on various conditions.

According to the results of this experiment, the rotation speed of the disk (5) is 700 tp1
It was about 1 or more.

According to the above-described first aspect of the present invention, by utilizing the repulsive force of a permanent magnet, a large rotational force can be obtained without using windings or wires.

Here, the rotation caused by the micro motor Q of the small disk helps in stable motor rotation.

Moreover, this requires only a small amount of power. Since the micromotor can be driven by a dry cell battery of 1.5V, it can be started easily even outdoors, and since the motor body has no wires, its structure is simple and its manufacture is easy. It would also be possible to reduce the weight by using materials such as plastic.

However, it would be convenient to use a commercially available micromotor, which would allow for mass production and economically reduce costs.

Note that the following may be considered as an implementation mode for this consideration. In other words, by using U magnets (7) as permanent magnets and arranging them as shown in Figure 2, it is possible to use the repulsive force between the north poles or between the south poles, thereby increasing the rotational force. It is.

Further, a small circular plate and an annular plate (8) are arranged concentrically as shown in Fig. 3, and a permanent magnet (9) is placed on each plate.

00) are arranged radially, rotational force can be obtained by using attractive force instead of repulsive force.

However, since the rotor body has an annular shape, it is unavoidable that the rotor body is structurally weak.
