Abstract
A motor includes a base, a stator, and a rotor. The base includes a shaft tube having an open end and receiving an inner assembly. The stator is mounted to an outer periphery of the shaft tube. The rotor is rotatably coupled to the inner assembly. The stator includes an insulating bobbin unit having an extension extending in a radial direction to the open end of the shaft tube. The extension includes an engagement hole. The shaft tube includes a positioning member having an engaging section engaged in the engagement hole. The insulating bobbin unit is fixed by an end of the engaging section. The engagement stability of the stator is enhanced by engagement of the positioning member of the base and the insulating bobbin unit.
