Patent abstract

In a stator winding, series coils are connected in parallel. One series coil includes series-connected U phase coils that are wound oppositely in direction by turns in the order in which the coils are series-connected and that are arranged in the manner that one and the other coil sets of the U phase coils are separated in the circumferential direction of a stator core and are opposite to each other in the radial direction thereof. The other series coil includes series-connected U phase coils that are wound oppositely in direction by turns in the order in which the coils are series-connected and that are arranged in the manner that one and the other coil sets of the U phase coils are separated in the circumferential direction of the stator core and are opposite to each other in the radial direction thereof.
