Method of assembling an electric motor

摘要

A stator assembly of a motor comprises a plurality of yokes fabricated by laminating a plurality of steel plate sheets having predetermined length; a plurality of poles coupled between the yokes and fabricated by molding magnetic material using a mold; and a plurality of bobbin bodies, on which coil for generating induced magnetism is wound, covered on outer portions of the poles, and the yoke is fabricated by laminating a plurality of steel plate sheets and the pole and the bobbin body are fabricated in a powder metallurgy method to reduce the material cost and to improve a function of the motor.
