This paper analyzes the principle of sine-wave phase current at microstepping driving for 3-phase hybrid stepmotor. A current-controlled generation circuit of PWM is designed. A microstepping driving system working under high voltage and high current with IGBTs is realized. The results of experiment indicate that the designed microstepping driver has good torque-frequency characteristic and it can eliminate surging at low frequency.
