摘要
本文利用无刷直流电机的数学模型 ,推导并仿真分析了任意平顶宽度梯形波反电动势无刷直流电动机在矩形波和正弦波两种电流驱动下的转矩脉动情况 ,得出在梯形波反电势平顶宽度减小到一定数值后 。
For the BLDCM which has a general crest width of the back EMF waveform, two kinds of torque ripple conditions when drived by square wave as well as by sine wave current are deduced based on the mathematical models. Simulation analysis indicates that sinusoidal current driving is more favorable to minimizing the torque ripple when the crest width of the back EMF waveform is less than a certain value.
