Abstract

A simulation model for the performance prediction of brushless DC drives is used to investigate the speed control obtained from modulation index and commutation advance variations for a motor of complex magnetic circuit geometry powered by a sine-coded PWM (pulsewidth modulation) inverter. The results of the study show the effects of motor model complexity on voltage and torque. Optimum performance conditions in the field-weakening mode are determined, and the value of motors using sinusoidal induced voltages is explored.
