Abstract

PURPOSE:To keep stable rotating force by arranging permanent magnets onto a large rotating disk and by providing numerous rotating small disks driven by a micromotor, on which permanent magnets are also arranged, on the outside circumference of this large disk. CONSTITUTION:A micromotor 5 is driven by a battery 6, with which small disks 1 and 7 directly coupled to it are rotated. Several pieces of permanent magnet 3 is symmetrically arranged onto the disks 1 and 7. Onto the same surface of this small disk 1 a large disk 2 to be the rotor of a motor is arranged, onto which several pieces of permanent magnet 4 are symmetrically arranged. A large disk 2 is thereby rotated stably by the resiliency of permanent magnets 3 and 4 and the output is taken out of an output shaft 10.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention includes permanent magnets arranged symmetrically on a large rotating disk serving as the main body of a motor rotor, and permanent magnets arranged symmetrically around the outer periphery of the large rotating disk. This invention relates to a composite magnetic gear type motor that generates stable rotational force through the repulsion of symmetrically arranged permanent magnets on many rotating small discs driven by micro motors.

Conventionally, internal combustion engines such as electric motors and gasoline engines have been used as drive sources for various types of equipment used outdoors. Electric motors are generally more efficient and economical, and provide better operation and handling. However, it cannot be operated independently without a power source, and even if there is a power source, a fixed wiring facility is required for this purpose. On the other hand, internal combustion engines such as gasoline engines can be operated independently and do not require fixed facilities, but there are many problems such as refueling and handling.

Furthermore, the presence of windings in electric motors makes the motor structurally complex, which is less desirable in terms of cost.

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

(b) The micro motor (5) is driven by a storage battery (6), and the small disc (1) (
7) rotates. A permanent magnet (3) is placed on this rotating small disk.
are arranged symmetrically.

(b) On almost the same plane as these small rotating disks, as shown in Figure 1, a rotating disk (2
) is placed on this disk as well.

Also, several permanent magnets (4) are arranged symmetrically.

(c) The large disk rotates stably due to the repulsive force of the permanent magnets (3) and (4). When disc (1) and disc (2) have the same polarity of magnets during rotational motion and take positions that face each other, the two repulsive forces are strong and the rotational force of the large disc becomes large.

(The air gap between the permanent magnets should be as small as possible. In the present invention, it was set to 3 mm.) In order to increase the rotational force, several small disks (1) were installed as shown in Figure 1. In the layered structure of small disks as shown in FIG. 2, there are several tens of small disks in total. Although it depends on various conditions, experimental results show that the number of revolutions of the disc (2) is between 1000 and 1
About 200rpl.

The output was several tens of W.

(e) All micromotors were connected in series, and a storage battery was connected to this. The terminal voltage per 21 micromoors was 08 to 1.5 .

(f) Several small discs (1) have their rotating shafts connected by a timing belt (9) to maintain two-rotation synchronization and improved starting characteristics. In addition.

The output is taken out from the output shaft α0.

According to the above two aspects of the present invention, a large rotational force can be obtained by utilizing the repulsive force of the permanent magnet.

A storage battery is used to drive the micromotor, and the terminal voltage of the micromotor is approximately 1.5μ which is sufficient. Therefore, the two motors are useful as a drive source for various types of equipment outdoors, and are easy to start.

It should be noted that the weight of the motor body could be reduced by using plastic or the like.

Note that the following may be considered as an implementation mode for this consideration.

In other words, as shown in Figures 3 and 4, this motor has a cup-shaped structure, and small discs (15) are arranged not only on the outer periphery of the large disc (α, 0) but also on the inside. It is thought that it is possible to increase the rotational force and output by increasing the number of small disks (product), (product), (15), and (16).

In this case as well, the micromotors on the inside and outside of the large disc are all connected in series to improve synchronization of one rotation and the starting characteristics.
