Abstract
A flywheel having a molded cage formed around a plurality of magnets attached to the flywheel. The cage extends into one or more grooves formed in the flywheel to resist the shrinkage of the cage inside diameter as it cools following an injection molding process. The gap between the cage and magnets and an adjacent stator is precisely controlled and minimized. Shutoff surfaces formed on the flywheel function as a portion of the die for injection molding of the cage.
