复合笼条转子异步电动机起动过程的仿真分析

Analysis to Starting State of Induction Machine with Compound Cage Rotor by Simulation

根据交流电机统一理论,建立了不考虑漏磁饱和影响的复合笼条异步电动机的数学模型。基于MATLAB语言对一台复合笼条异步电动机起动性能进行了仿真计算,仿真计算结果与实际结果基本相吻合。同时,研究了转子电阻、漏感的变化对电机起动性能的影响,得出了一些有益的结论。

According to the theory of AC motor, the math-ematic model of induction machine with compound cage rotor is built up ignoring effect of leaking magnetic saturation. Based on MATLAB language, the starting performance of an induction machine with compound cage rotor is calculated by simulation and the result of simulation is consentaneous with practical result basically. Simultaneously, the effect of resister and leakage reactance to starting performance of motor is studied and some helpful conclusion is got.
