摘　　要：以一台5.5 kW鼠笼式异步电动机为例,建立了二维瞬态电磁场物理模型。利用有限元方法分析转子断条故障对电动机电流、转矩和转速等性能的影响,得到了不同断条程度对电动机性能影响的规律。Taking a 5.5 kW squirrel cage asynchronous motor as an example,two-dimensional transient electromagnetic field model is established.Influence on motor performances such as current,torque and speed due to the rotor broken bars are analyzed by the finite element method and the influence rule on motor performance due to different degrees of the broken bars are obtained.
