摘要
Annular portions of a first interphase insulting sheet have void portions. After a U-phase coil is inserted in wave winding, bridge portions are mounted to slots for an adjacent V-phase coil. The void portions are formed at positions corresponding to the bridge portions that are disposed between any two of coil ends. The annular portions are stretched to form a generally pentagon shape, which facilitates mounting of the V-phase coil. The void portions formed at positions that do not need insulation will not impair the insulating function of the first interphase insulating sheet. The void portions formed in alignment with extension of the bridge portions will not cause a drop in the strength of the annular portions.
