鼠笼电机转子导条及端环断裂问题研究的仿真方法

A Method of Simulation of Squirrel-cage Motors with Rotor-rar and End-ring Faults

提出了一种用于仿真分析具有转子导条又端环断裂故障的鼠笼异步电机的运行行为的方法。因而可方便地描述具有任意断裂导条和端环数的转子故障状况。同其它方法相比，不但可以用于电机的稳态分析，也能用于其暂态分析。

In this paper,a method used to simulate the squirrel-cage motors with rotor-barand end-ring faults is presented. In our analysis,the stator is still represented by three-phase windings,but each loop of the rotor is considered as a single-phase winding,so it is convenient to describethe situation of the motor with any number of broken rotor-bar and end-ring.Compared with othermethods,the method of this paper can be used to analyse both the steady-stats and the transient stateof cage motor with rotor faults.
