Abstract
The windings () wound around each of the teeth () form two coil groups () of three-phase concentrated windings which are disposed point-symmetrically to each other with respect to the rotational shaft. Each of the coil groups () includes a first coil (), in which the windings () are wound around the teeth in a forward direction, and a second coil (), in which the windings () are wound around the teeth in a reverse direction. When each of the teeth () is allocated with a U phase, a V phase, and a W phase in this order in a circumferential direction so that the first coil () wound for each phase is set to be coils of the U phase, the V phase, and the W phase, and the second coil () wound for each phase is set to be coils of the −U phase, the −V phase, and the −W phase, the coils of the U, −W, V, −U, W and −V phases are electrically connected between the adjacent segments () in this order.
