ROTOR INCLUDING ANTI-ROTATION FEATURE FOR MULTI-POLE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2013/138406
Kind Code:
A3
Abstract:
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 comprises discrete indentations extending into the peripheral surface and engaged by corresponding discrete portions of an end of the rotor cover, the second anti-rotation feature comprises tabs that extend axially from the engagement surface of the endcap and engage in spaces defined in at least an end portion of the multi-pole structure, and each anti-rotation is suitable for transmitting a torque on the multi-pole structure.
