ABSTRACT:
A stator of an electric motor includes teeth, coils each wound about one of the teeth, and a yoke. Each tooth includes a tooth main body and a tooth reinforcing portion, which is integrally molded with at least a part of the surface of the tooth main body. The tooth main portions are formed a powder magnetic core material. The tooth reinforcing portions have a higher mechanical strength than that of the tooth main bodies. The yoke has fitting openings each receiving one of the teeth. Each tooth is fitted to the corresponding fitting opening in such a manner that the tooth reinforcing portion contacts a wall surface that defines the fitting opening.
