MOTOR SYSTEM AND FAN MODULE USING THE SAME

摘要

A motor system includes a stator magnetic pole, a driving unit and a stop control unit. The stator magnetic pole is adapted to couple with a rotor for the rotor to rotate relative to the stator magnetic pole. The stator magnetic pole has first and second ends. The driving unit is electrically connected with the stator magnetic pole and drives the rotor to rotate by changing the polarity of the stator magnetic pole. The stop control unit is electrically connected to the stator magnetic pole and the driving unit. If the rotor rotates when the motor system is not electrically powered, the stator magnetic pole generates electricity that changes the path of the electric current flowing through the stop control unit, and the stator magnetic pole outputs an electric current from the first end to the second end or from the second end to the first end thereof. In addition, a fan module is also disclosed to solve the problem.

1. A motor system comprising:
a stator magnetic pole having first and second ends; a rotor rotatably coupled with the stator magnetic pole; a driving unit electrically connected with the stator magnetic pole and driving the rotor to rotate by changing a polarity of the stator magnetic pole; and a stop control unit electrically connected to the stator magnetic pole and the driving unit, wherein if the rotor rotates when the motor system is not electrically powered, the stator magnetic pole generates electricity that changes a path of an electric current flowing through the stop control unit, and the stator magnetic pole outputs an electric current from the first end to the second end or from the second end to the first end thereof, thereby stopping the motor system.
