These are justified by simulation . 5 . the principle of compensating pulsating torque is proposed 分析了谐波加入法消除转矩脉动的原理和摘要不足。
So the compensation of pulsating torque is very importance for the application of pmsms 因此,对无刷直流电动机的应用,必须考虑其转矩脉动的抑制问题。
The pulsating torque components caused by stator current divergence from ideal conditions are studied 消除转矩脉动可以通过对定子电流加入谐波的方式完成。
At the meantime , there are the problems about the pulsating torque output and emi existed in the controller and we analyze the causes 同时,指出了该系统中存在的转矩脉动大、电磁干扰等问题,并分析了其原因。
The main disadvantage of pmsms is its pulsating torque . torque smoothness is an essential requirement in a wide range of high - performance motion control applications 然而,无刷直流电动机具有较大的转矩脉动,而对于这些应用场合,转矩平滑通常是基本要求。
