| 摘 要： | 基于电磁学磁感回路分析,建立了异步电动机仿真模型。结合分析异步电动机内部故障时定子阻抗的变化,得到异步电动机启动过程、正常运行、发生故障后的机端侧电流、转子转速、定转子角差、转矩等各电气量的数据变化,为电动机模型仿真提供了一种基于磁感回路参数的新仿真方法,以便于为电动机内部故障分析提供定量分析。

| Abstract: | This paper introduces a asynchronous motor model which is established base on the analysis of electromagnetic induction circuit.Analyzing the stator impedance change of asynchronous motor with inner faults,the change electrical data such as the motor terminal current,rotor speed,relative angle between stator and rotor,speed-torque in the starting process,running process and fault happening process of asynchronous motor can be got,which put forward a new simulation method based on the magnetic Induction circuit parameters for the asynchronous motor simulation.At the same time this method is useful to quantitative analysis the inner fault of asynchronous motor. |
