ABSTRACT:
A hybrid alternator has a rotor with a plurality of permanent magnets disposed between opposing claw-pole segment pole fingers. The magnets are radially retained by the pole fingers during rotation. The magnets are supported during high speed rotation characterized by outward flexure of the pole fingers at surfaces inboard of extreme ends of the magnets thereby reducing load stresses on the magnet.
