Abstract
A magneto flywheel includes arcuate ceramic magnets of non-uniform radial thickness. A rotor for the flywheel is made of soft material. The magnets of the magneto flywheel have a set of radial poles of alternating polarity, and an other set of opposite poles directed toward the cylindrical periphery of the magneto rotor. A ferromagnetic band of deflectible material with the surface projection is disposed between the rotor and the magnets.
