| 摘要 |
The present invention relates to a motor structure, which includes a base having a shaft tube centrally, in which a bottom portion of the shaft tube is sealed for placing a bearing therein, and at least a reference plane is provided on the outer periphery of the shaft tube; a rotor having a spindle disposed centrally therein for passing through the bearing and rotating therein; a stator module disposed on the outer periphery and positioned on the reference plane. Besides, an urging part is disposed on an inner periphery of the top insulation sleeve of the stator module to urge against the bearing so that the precise assembling position of the stator module can be definitely defined to prevent the bearing from getting loose due to high assembling position and to prevent the fracture of the urging part due to low assembling position.
