Abstract

PURPOSE: To reduce the size of an electric ally driven motor without deteriorating the performance, such as a torque and an irregular rotation by molding a coil with a yoke injectionmolded, using resin mixed with magnetic material, such as iron powder.
CONSTITUTION: A coil 3 is wound in advance and set in an injection mold. A housing 5 is simultaneously set in the mold. A yoke 4 is composed by mixing with a soft magnetic material, such as iron powder in resin, and injected in the mold in which the coil 3 and the housing 5 are set. Accordingly, it is not necessary to wind the coil between narrow slots, but the shape of the coil can be freely fabricated. As a result, the number of poles of the slots can be easily increased, and the winding efficiency can be enhanced.
