摘要

The stator (52) of the electric motor (50) includes teeth parts (52a) formed from electromagnetic steel sheets, windings (52) wound around the teeth parts (52a) and a yoke section (52c) produced of magnetic material, which accepts the windings (52b) and the teeth parts (52a). The yoke section (52c) includes a steel tube. The yoke section (52c) is formed of a magnetic iron material with a low carbon component.
