| Abstract: | A new controller for 3-phase brushless DC motor was designed based on conventional closed-loop feed-back control theory and PWM theory.The circuit had the advantages of high motor supply voltage,large output current,and accurate zero point,and it also had a 100% adjustable high side duty cycle and over-current protection function.It is a real four-quadrant torque motor controller. |
