多闭环直流拖动电控系统

直流拖动电控系统为了实现平稳的调速过程,主要采用直流电动机,因为直流电动机调速方便,只要改变电机的输入电压或励磁电流,就可以在宽广的范围内实现无级调速,而且在磁场一定的条件下它的转矩和电流成正比,从而使得它的转矩易于控制、转矩的调节性能和控制性能比较理想。

Electric Control System of Multiple Close-loop DC Trailing

In order to achieve smooth speed process,DC drive electric control system mainly adopts DC motors,because of convenient DC motor speed control,as long as the input voltage or the motor excitation current is changed,variable speed control can be achieved within a wide range scope and under certain conditions in the magnetic field,it is proportional to the torque and current,making it easy to control torque,torque regulation performance and control performance are ideal.
