MICROSTEP DRIVING MODE OF THREE PHASE HYBRID STEPPING MOTOR

摘要

This paper describes a microstep driving mode with constant torque for three-phase hybrid (HB) stepping motor. The mathematical model of three-phase HB stepping motor is analyzed. On the study of harmonic torque of the motor, the method to compensate harmonic torque is presented. So the step resolution and step accuracy can be improved. The microstep performances are verifiel by the result of experiments.
