Therefore, Pulsating torque has very little effect on the starting of motor.
因此脉动转矩对电动机起动影响很小。
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。
Frequency of this pulsating torque is six times as high as that of the fundamental current.
这种脉动转矩的频率为基波电流频率的六倍。
