ABSTRACT:
A stator winding is configured into a polyphase alternating-current winding by joining together end portions of a plurality of winding sub-portions in a vicinity of each of axial ends of coil end groups within a predetermined circumferential range. Covers are fitted onto each of ancillary connection portions constituted by joint portions between the end portions of the plurality of winding sub-portions so as to closely fit onto an inner circumferential surface, an axial end surface, and an outer circumferential surface of each of the ancillary connection portions, the covers each being filled with a first electrically-insulating resin.
