波动电流 undulating current
fluctuating current
- 经改进控制回路后有效根除了真空泵电流波动的故障。
The trouble of fluctuating current for vacuum pump has thoroughly been removed through an improvement of controlled circuit. - 实验发现亚稳态电流波动峰具有快速上升、缓慢下降的特点。
It is found that the current fluctuations of the metastable pitting occurred with a characteristic of quick increase and slow decrease. - 在变速参数中影响电机瞬时电流波动最为显著的因素依次为变速波形、变速幅度和变速频率。
The significant factors which exert an influence on instantaneous fluctuation of motor current are in sequence :Vari-speed wave form, vari-speed amplitude and vari-speed frequency.
