ABSTRACT:
A permanent magnet rotor, wherein a magnet cage includes a plurality of equally spaced, longitudinally extending, selectively shaped legs, a sleeve mounted within the inner surfaces of the legs, and a shaft press fitted through the sleeve. A plurality of wedge-shaped magnets are inserted between adjacent legs around the sleeve, retained by the shapes of adjacent leg surfaces. A cover plate having chamfered slots is mounted on the leg ends against the magnets. The ends of the legs are staked in the chamfered slots to secure the rotor assembly.
