Patent ID: 7078841

Claim:
A magneto-generator, comprising: a flywheel having a cylindrical peripheral wall and a flat bottom wall which closes said cylindrical peripheral wall at one end thereof; a plurality of magnets disposed on and along an inner peripheral surface of said cylindrical peripheral wall of said flywheel; a generator coil disposed internally of said flywheel in opposition to said magnets for generating electricity under the action of electromagnetic induction taking place between said magnets and said generator coil; ventilating through-holes formed in a joined portion between said cylindrical peripheral wall and said flat bottom wall of said flywheel so as to extend in continuation partially through both said cylindrical peripheral wall and said flat bottom wall; and a plurality of upstanding fins disposed on said flat bottom wall for generating forced air currents flowing from interior to exterior of said flywheel by way of said ventilating through-holes upon rotation of said flywheel to thereby cool said generator coil.
