ABSTRACT:
A phase winding of a stator winding comprises one or more pairs of interconnected partial coil, each partial coil formed of sequentially connected U-shaped segment pairs, each pair comprising a large segment and small segment. Two segment legs, of the large and small segment respectively of such a pair, constitute first and second conductor layers of a first stator slot and have their tip portions mutually connected. The remaining two segment legs respectively constitute fourth and third conductor layers of a second slot that is distant by one pole pitch, and have their respective tip portions mutually connected.
