| 摘 要： | 针对五种PWM调制方式对永磁无刷电动机换相转矩脉动的大小进行了分析和比较。理论推导得到：pwm_on方式的换相转矩脉动最小；Hpwm_Lpwm方式的换相转矩脉动最大；其余三种的换相转矩脉动在其两者之间：经仿真分析和实验观测，验证了理论分析的正确性。

| Abstract: | The magnitudes of the commutation torque ripple of permanent magnet brushless DC motor were analyzed and compared with 5 PWM modes, resulting in the least commutation torque ripple as pwm-on, the maximum as Hpwm-Lpwm, the others in between them. And the correctness of above conclusions were verified by simulation and experiment in this paper. |
