Abstract
A 10-pole 12-slot permanent magnet synchronous motor comprises a plurality of teeth. From among two adjacent teeth around which coils of the same phase are wound adjacent to each other, the rotational direction width of a winding portion of a first tooth placed in front along a rotational direction of a rotor is set narrower than that of a winding portion of a second tooth placed behind along the rotational direction of the rotor. With this configuration, the circumferential length of the coil wound around the first tooth can be shortened with suppressing increase in iron loss in the winding portion of the first tooth.
