Zusammenfassung

Abstract There is disclosed herein an apparatus and assembly method, 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 thereagainst by the shapes of adjacent leg surfaces. A cover plate having chamfered slots formed therein 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.
