Abstract
A synchronous motor includes a stator that includes nine teeth that are divided into three phases, each of which includes three adjacent teeth, windings being concentratedly wound around the teeth. The circumferential width of a tip portion of a central tooth among three teeth forming each phase is made smaller than the circumferential widths of tip portions of both-side teeth, and the tooth thickness of the tip portion of the central tooth is made smaller than the tooth thicknesses of the tip portions of the both-side teeth.
