    摘要: A motor includes a rotor, a sensor unit, an offset unit, a rectification unit and a modulating unit. The sensor unit outputs a first signal in accordance with a magnetic field variation of the rotor. The offset unit is coupled to the sensor unit, and outputs a second signal in accordance with the first signal. The rectification unit is coupled to the offset unit, and outputs a third signal in accordance with the second signal. The modulating unit is coupled to the rectification unit, and outputs a control signal in accordance with a result by comparing the third signal with a periodic signal. The modulating unit controls a reverse rotation of the rotor smoothly in accordance with the control signal. A control method of the motor is also disclosed.
