摘要
无刷直流电机(BLDCM)电磁转矩脉动产生于电流换相时,分析了由三相全桥逆变器驱动的无刷直流电机在五种PWM斩波调制方式下的换相过程及其所产生的转矩脉动,并找出了最佳的PWM斩波调制方式,仿真及实验结果与理论分析一致。
Electromagnetic torque ripple of brushless DC motors （BLDCM） generated in the current commutation interval, this paper presents a comprehensive analysis on the generated torque ripples and phase commutation in the six switch, Three-phase inverter brnshless DC motor drives, and find out the best PWM pattern for BLDCM, The simulation and experimental results verify the amplitude of the phase current and torque ripple under 5 kinds of PWM pattern, which are consistent with theoretical analysis.
