特种电动机高压阀门准确制动的仿真计算

Accurate Control of Special Electromotor High Press Valve

对于特种异步电动机拖动的高压阀门 ,切断电动机交流供电电源后 ,在电机的定子绕组中通入适当的直流电流 ,产生直流磁场 ,使电机进行能耗制动 ,让阀心和电机转子的能量 ,包括动能消耗在转子的绕组中 ,达到准确停车的目的。

When AC power is cut off ,DC power exerting on coil of stator forms DC magnetomotive force,motor can apply break in energy consumption. Thus the valve can accurately stop. And the computor simulation is introduced.
