Abstract

The flux reversal machine (FRM) is a new brushless doubly salient permanent-magnet machine. Its operation is similar to that of the brushless dc motor, so it can be driven by 120° square wave voltage and use pulsewidth modulation (PWM) pulse patterns in two-phase feeding scheme to control the speed. This paper introduces PWM modes used in FRM control system, and analyzes their different influences on the performances of the FRM using a time-stepped voltage source finite-element method. To prove the propriety of the proposed analysis method, digital signal processor (DSP) installed experimental devices are equipped and the experiment is performed.
