초록
This paper presents characteristics analysis of brushless DC motor(BLDCM) which driven by two types of PWM mode. The phase current and torque ripples are generated differently at each PWM mode. So they have a different influence on motor characteristics. In this paper, we have analyzed characteristics of BLDCM using time-stepped voltage source finite element method. The effect of two types of PWM mode had been confirmed by comparing each phase current and torque ripple waveform. The compared simulation result is useful to select a better PWM mode.
