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。
A pulsating torque component can be compensated by inject a selected harmonic component to the phase current.
消除转矩脉动可以通过对定子电流加入谐波的方式完成。
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。
