摘要:
An outer rotor type brushless motor of the present invention comprises: a rotor portion having a rotor frame, a shaft, and a rotor magnet; a bearing housing; a stator portion facing the rotor magnet and having a stator core, a plurality of first salient pole portions extending toward the rotor magnet from the stator core, an insulation surrounding the first salient pole portion, and a winding around the first salient pole portion through the insulation; and a torque holding portion provided on an inner side of the outer circumference portion of the rotor frame and an outer circumference of the bearing housing, and having a plurality of second salient pole portions disposed coaxially with the stator core and extending toward the rotor magnet, where the first salient pole portions and the second salient pole portions are provided in different numbers.
