Abstract
A flywheel magneto generator is disclosed, which includes a flywheel rotor, a stator disposed in the flywheel rotor and a signaling stator disposed outside said flywheel rotor. The flywheel rotor comprises a bowl-like flywheel, a plurality of arcuate permanent magnets engaged at the ends thereof with each other and aligned on the inner surface of the peripheral wall of the flywheel, and securing means for securing the magnets to the flywheel. The invention is characterized in that the securing means comprises a single wedge-like magnetic member interposed between the opposing ends of a pair of the permanent magnets and a screw coupling for coupling said wedge-like magnetic member to the peripheral wall and for urging said wedge-like magnetic member radially outwardly. The screw coupling is provided with an extending member of a magnetic material extending through the peripheral wall of the flywheel, magnetically insulated from the peripheral wall and having an outer end exposed outside the flywheel. The signaling stator is provided adjacent the peripheral wall of the flywheel so that the signaling stator is magnetically associated with the exposed end of the screw coupling.
