摘要
A motor unit includes a motor, a power source, and a motor control circuit. The power source supplies electric current to the motor. The motor control circuit is coupled to the motor and the power source, and includes a driver, a detector, and a controller. The driver controls duty cycle of the motor. The detector is coupled to the driver, and is operable so as to detect amount of the electric current supplied by the power source to the motor. The controller is coupled to the detector, and enables the driver to control operation of the motor at a reduced duty cycle reduced from an initial duty cycle when the amount of the electric current detected by the detector is higher than a predetermined reference threshold value configured in the controller. A method for protecting a motor from burnout is also disclosed.
