Abstract
Provided is a synchronous motor comprising a rotor that includes magnetic poles arranged at equal intervals in the circumferential direction, and a stator that includes stator teeth arranged at intervals in the circumferential direction. Stator teeth other than a reference tooth are displaced from positions corresponding to integral multiples of the phase difference of two-phase alternating currents with respect the stator tooth in electrical angle. Both a first-type coil supplied with a first phase and a second-type coil supplied with a second phase are wound by concentrated winding on the stator teeth arranged at the displaced positions.
