摘要
三相绕线式异步电动机转子回路外接并联阻抗 ,可以改善起动性能 ,简化控制电路 ,适用于重复短时工作制负载的起动控制。讨论了阻抗参数的计算方法。
That rotor loop of three-mutually coil asychronism motor connects with parallel connection impedance can improve starting performance and predigest control circuit.It is the same with starting control for repeat working load.The method of impedance parameter numeration is discussed in this paper.
