Abstract:
A modulated litz wire wherein the braid of a litz wire is varied along its length such that bulkier sections are located at the end-turns of a motor, while more compact parallel stranded sections are located in stator slots or magnetic gaps. Variations may include parallel stranded sections replaced with a longitudinal twist for improved handling or improved current sharing in strands.
