脉动电流 meaning in English

current ripple
pulsating current
pulsating-current
pulsatory current
ripple current

Modified formula for sensorless dc motor speed estimation was proposed through the test for relationship between the current ripple frequency and the rotation speed in a 4 - pole dc motor
摘要根据4极直流电动机的转速与脉动电流频率关系的实验结果，对现有的无传感器直流电动机测速公式提出了修正意见。
A common example is shown in figure 11 . 34 where the resonant circuit formed by an inductive power line and its decoupling capacitor may be excited by pulse currents drawn by the ic
图11 . 34所示的例子中，电源线的电感与去耦电容形成了谐振电路，芯片工作时产生的脉动电流，可能会激励该电路（产生振荡）。
The new modified formula not only meets with our experiment result , but also can explain the examples of relationship between the speed and the current ripple frequency of dc motors in the literature
新的修正公式不仅能够解释文中的实验结果，也能满足以往文献提出的直流电动机转速与脉动电流频率之间的关系。
