Abstract :
The dynamic characteristics of a flux reversal machine are analyzed using finite-element method coupling with the equation of the driving electric circuit and the motion equation. In this computation, sine-wave and rectangular-wave current drives are used as the driving conditions like a brushless motor, and the results are compared in respect of torque ripple and iron losses. Considering the torque ripples, driving a skewed motor with rectangular wave input is cost effective. However, among the parts of the motor, the rotor experienced high variations of the flux, which results in high losses.
