Abstract

This paper carries research on the method of smooth method of Brushless DC Motor. Brushless DC motor applied in human skeleton booster is required to switch frequently among four-quadrant operation states of forward rotation, backward rotation, electro motion and braking control. Basically, this switch is expected to be soft. That means it is unexpected that motor comes about the phenomenon of impact of great force, speed mutation and so on. According to the requirement, the paper presents the design of driving circuit of brushless DC motor and put forward a corresponding control method. In the end, the paper proved the correct of this method by using simulation and experimental data.
