Highly efficient permanent magnet synchronous motors are widely used for electric appliances and electric vehicles. In order to further improve the efficiency of the permanent magnet synchronous motor, it is necessary to simulate the motor characteristics under the actual operating condition. In this study, we introduce numerical results of PWM drive using JMAG-Designer Ver.17.1 with control circuit modeling functions. We describe the influence of eddy current loss on analysis results by using control circuit modeling functions. In addition, we also report the results of loss comparison of sinusoidal drive and PWM drive at typical operating points.
