Abstract
A stator winding includes forty-eight winding bodies 22 that are each produced by winding a jointless continuous conductor wire that is coated with insulation, and that are arranged at a pitch of one slot in a circumferential direction so as to be mounted into a first slot 131, a second slot 132, and a third slot 133 that are circumferentially consecutive at an angular spacing of six slots. The winding bodies 22 are configured into a δ-shaped coil pattern that is formed by inserting the conductor wire 19 sequentially into the first slot 131, the second slot 132, the third slot 133, and the second slot 132, so as to alternate an axial direction of insertion into the first slot 131, the second slot 132, and the third slot 133.
