voltage gradient

During the research of 11kW rare earth permanent magnet brushless DC motor starting process,the control strategy by slope voltage was used to reduce the higher current.

在对11 kW稀土永磁无刷直流电动机起动过程研究中,针对起动电流过大,采用斜坡电压的方法进行控制。

Via controlling the slope voltage and the time that ever step postpone, the fault that the torque increased as along with the phase voltage of stator growing was improved.

基于89C51单片机的软并网装置成功地应用在定桨距失速型600kW风力发电机组的软并网系统中,该软并网装置通过控制斜坡电压的步长和电压平台的延迟时间,最大限度的改善了传统的斜坡电压软启动方式造成的电机转动力矩随定子电压的升高,转矩 时间曲线呈抛物线形发散增大的弊端。
