摘要

A stator winding (20) has a plurality of conductor members (293A, 203B) forming coil ends, and each of the conductor members (203A, 203B) of the coil ends is hardened and heat-treated to have hardness which changes along the length of conductor members (293A, 203B). Therefore, the stiffness of the coil ends changes and resonant vibration of the stator (21) can be reduced.
