However, a larger output can be obtained by increasing the rigidity of the support frame and reducing the gap.
- the permanent magnet 16, the driven permanent magnet 46, and the driving permanent magnet 58 are all two-layered and circular, but the present invention is not limited to this, and one or more Three or more sheets may be stacked, and the shape is arbitrary such as a square or trapezoid. Alternatively, when the radius of the rotor is small, for example, as shown in FIG. 16, a curved magnet 150 whose entire surface is convexly curved to one side is preferable.
