Abstract
A dual-voltage brushless motor () includes a casing, a motor shaft () rotatably coupled to the casing, a rotor fixedly connected to the motor shaft (), and a stator () configured to face the motor. The rotor contains a plurality of permanent magnets, and the stator () includes a first set of winding and a second set of winding. The first winding is electrically isolated from the second winding. The dual-voltage brushless motor () is adapted to be driven when the first set of winding receives a first control signal or when the second set of winding receives a second control signal. By configuring two separate motor controllers of the motor, the motor () can be operated under different power supplies such as AC power supply and DC power supply. As a result the application of the motor is greatly extended.
