DESCRIPTION OF THE PREFERRED EMBODIMENTS 1. The fixed rotor (2) and the drum rotors A (4), B (5) and C (6) are always (non) magnetic materials. However, if the disc portion of the drum has a certain distance from the position of the fixed magnet, a ferromagnetic material can be used. 2. The magnet to be fixed is stored in a stainless steel case or the like made of a permanent (non) magnetic material, and the storage case is fixed so as to withstand the centrifugal force of the drum rotor. 3. Since the facing magnets may come into contact at the time of starting the rotor or at the time of overload, attach a cushioning material. 4. Flywheel (1) on the outermost drum rotor

The output shaft (13) is fitted between a so-called double bearing, which is a bearing for fixing the rotating body by fitting (6), and fixed to the drum rotor (5) or the flywheel (14). (FIG. 3) 6. A method in which a fixed rotor and a plurality of drum rotors are taken as one set, a plurality of sets are arranged coaxially, and an outermost drum rotor is connected.

[0006]

According to the method of arranging the magnets of the rotating body using the permanent magnet of the present invention, the two rotating bodies having different diameters are separated from each other by two axes, and the two rotating bodies are separated into a small rotating body in a non-contact state. When the power source is connected and rotated, the same rotation speed is transmitted to a large rotating body via magnetism, and the rotation is continued in parallel. Here, non-contact means that the two large and small rotating bodies are not connected by a belt or a gear. A plurality of rotating bodies are sequentially increased in diameter and rotated in the same manner. The input torque of the small rotating body is T1, and the torque of the output shaft attached to the large rotating body is T2.
As a result, data of T1 <T2 is obtained.
