普通的直流电是指大小(电压高低)和方向(正负极)都不随时间(相对范围内)变化,比如干电池。脉动直流电是指方向(正负极)不变,但大小随时间变化。
原油形式,切碎,脉动直流电流从传统充电器生产效率较低的收费。
The crude form, chopped, pulsating DC current from conventional chargers produces a less efficient charge.
发现了手摇交流发电机演示实验中出现脉动直流电的奇异现象并对此作出了合理的解释。
The phenomenon of a pulsating direct current in demonstrative experiment of hand alternator is founded and the reasonable explanation is presented.
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。
So the compensation of pulsating torque is very importance for the application of PMSMs.
