Abstract
The present disclosure discloses a brushless DC motor braking system and method. during the braking process of the brushless DC motor, the busbar voltage value is controlled to always be between the high threshold of the busbar voltage and low threshold of the busbar voltage through the brake control module; and different PWM modulation signals are used to control the brushless DC motorto perform slow braking until stopping based on different busbar voltage states. Thus, in the present disclosure, the method not only ensures that the busbar voltage value continues to be maintained between the high threshold of the busbar voltage and low threshold of the busbar voltage, thereby protecting electronic components and circuits and extending their service life; but also avoids the hard braking method of direct conduction of the three lower transistors of the three-phase inverter in related arts.
