ABSTRACT:
A stator winding includes a plurality of winding sub-portions in each of which a strand of wire formed from a continuous wire is wound so as to alternately occupy an inner layer and an outer layer in a slot depth direction within slots at intervals of a predetermined number of slots and form a lap winding having two turns in each lap, the strands of wire folding over outside the slots at end surfaces of a stator core, four of the strands of wire constituting the winding sub-portions being housed so as to line up in each of the slots in a slot depth direction, turn portions formed by folding the strands of wire over outside the slots at a first end surface of the stator core being disposed circumferentially to form two rows in a radial direction, and turn portions formed by folding the strands of wire over outside the slots at a second end surface of the stator core being disposed circumferentially to form two layers in an axial direction.
