A stator manufacturing method for a motor includes an assembling step coupling a magnetic driving assembly onto an outer circumferential wall of a shaft tube, a mold combining step disposing the shaft tube and the magnetic driving assembly in an intra-cavity of a fixture unit, a glue injecting and forming step injecting a filling glue into the intra-cavity, with the filling glue solidifying into a protective glue coating with which the shaft tube and magnetic driving assembly are coated, a mold removing step removing the fixture unit from the shaft tube, magnetic driving assembly and protective glue coating, and a shaft tube seat coupling step providing a shaft tube seat having an engaging portion and coupling the engaging portion with the shaft tube, allowing the shaft tube, the magnetic driving assembly, the protective glue coating and the shaft tube seat to be coupled together to form a stator for the motor.

A rotation direction control method of a cooling fan is disclosed. The rotation direction control method includes a detection step, a determination step and a driving step. The detection step receives a temperature control signal from a temperature detection unit by a rotation direction control unit when a predetermined dust-expelling time period begins. The determination step determines whether a detected temperature is higher than a predetermined value based on the temperature control signal by the rotation direction control unit. The driving step controls the rotation direction control unit to keep outputting a cooling signal so as to drive a motor of the cooling fan for a cooling operation when the determination of the determination step is positive.
