Abstract
A stator includes an annular stator core and a stator coil. The stator core has U-phase slots, V-phase slots and W-phase slots sequentially and repeatedly provided in pairs in its circumferential direction. The stator coil has U-phase, V-phase and W-phase windings respectively received in the U-phase, V-phase and W-phase slots. In each of the slots, there are received 2×N in-slot portions of a corresponding one of the phase windings in radial alignment with each other, where N≧2. Each of the phase windings consists of a pair of sub-windings connected parallel to each other. Each of the sub-windings includes winding sections that are classified into N winding section groups. Each of the winding sections of (N−1) winding section groups is connected via only serial connection, and each of the winding sections of the remaining one winding section group is connected via both serial connection and parallel connection.
