counter 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)計的無刷直流電機穩(wěn)速控制系統(tǒng)用電機控制專用芯片ML4428實現(xiàn)了反電勢的檢測、換相和功率驅(qū)動；
With the mature technology and simple circuits, the counter-electromotive-force measuring can be used for detecting the rotor's position owing to no mechanical brush in the brushless DC motor.
根據(jù)無刷直流電機無機械電刷這一特殊結(jié)構(gòu)，采用反電動勢測量方法來檢測轉(zhuǎn)子位置，技術(shù)成熟、電路簡單；
