| Abstract: | whether there is current at non-commutation duration when the energized phase of brushless DC turns into floating phase affects the motor's operating performance greatly.Based on the working principle of brushless DC motors,This paper presents a simplified equivalent model for brushless DC motors,and reveals the conditions and calculation equation when current is generated in the floating phase of brushless DC motors.It puts forward the law of generated current in the floating phase in different pulse-width... |
