发明名称 Magnetization apparatus and magnetization method
摘要 A magnetization apparatus for magnetizing a magnetic material provided inside a yoke housing of a motor, which has a connector portion radially outward of the yoke housing, includes at least one pair of magnetization cores and a plurality of magnetization coils. The at least one pair of magnetization cores are provided to oppose to each other, wherein the at least one pair of magnetization cores have corresponding magnetization surfaces, which oppose to each other. The plurality of magnetization coils generate a magnetic field at the at least one pair of magnetization cores, wherein the plurality of magnetization coils magnetize the magnetic material in a state, where the yoke housing is provided between the magnetization surfaces. The at least one pair of magnetization cores defines a receiving recess therein for receiving the connector portion of the motor in the state, where the yoke housing is provided between the magnetization surfaces.
