back electromotive force

基本解釋

Using the motor control special chip ML4428, the counter electromotive force detection and back-EMF commutation were realized.
所設(shè)計(jì)的無(wú)刷直流電機(jī)穩(wěn)速控制系統(tǒng)用電機(jī)控制專用芯片ML4428實(shí)現(xiàn)了反電勢(shì)的檢測(cè)、換相和功率敺動(dòng)；
Accordingly, a cogging torque and noise are reduced without reducing a back-electromotive force, thereby obtaining a high efficiency.
因此，在不減小反電動(dòng)勢(shì)的情況下減小了頓轉(zhuǎn)扭矩和噪音，由此獲得高傚率。
