pulsating direct current 中文意思是什麼
pulsating direct current
解釋
脈動直流電-
Abstract in this paper the phase commutation and current curves of brushless motor variable - speed system are studied. according to the results that the pulsating torque is influenced greatly by the ratio of the direct current supply voltage and the electromotive force of the motor, an approach to reduce the pulsating torque is presented
本文通過對無換向器電動機模型的換相過程和電流波形的研究,得到換相轉矩波動受直流電源電壓和電動機電動勢幅值的比( u / e )的影響較大的結論並獲取了最佳u / e ,同時通過模擬研究了電流波形,提出了減小轉矩脈動的控制策略。
