Abstract

See full text

A permanently magnetizable rotor having a central rotor structure including a rotor shaft supporting a cylindrical backiron. The rotor further includes a multi-pole structure comprising circumferentially alternating pole elements, and a rotor cover extending longitudinally over the multi-pole structure. The rotor additionally includes an endcap including an engagement surface positioned in engagement with an end of the backiron. The endcap defines first and second anti-rotation features for preventing circumferential rotation of one or more of the pole elements about the backiron. The first anti-rotation feature is configured differently than the second anti-rotation feature and each anti-rotation feature defines a torque transmitting feature for transmitting a torque from different locations on the multi-pole structure.
