ABSTRACT:
A permanent-magnet generator includes a flywheel having a ringlike portion and a bottom portion which closes off one end of the ringlike portion and a plurality of protrusions bulging inward from the bottom portion of the flywheel. An irregular surface portion is formed in each of the protrusions for producing turbulence when the flywheel rotates, the irregular surface portion being irregularly shaped in section along a circumferential direction of the flywheel.
