摘　　要：考虑到机电特征参数变化对机械转子系统产生影响,建立一种基于SPWM(sinusoid pulsewidth modulation)技术的变频器笼形异步电机机械转子的机电耦合系统模型,并利用该模型对系统起动非平稳过程进行研究。结果表明,所建模型对机电耦合系统动力学规律研究有参考价值。Through the effects of the electromechanic characteristic parameter＇s change on the mechanic rotor have been considered, the electromechanic coupling system is composed of converter based on SPWM, cage type asynchronous machine and mechanic rotor has been established to study the rotor＇ s non - stationary process. The findings showed that the model can be availably studied the dynamical rule of the electromechanic coupling system in engineering.
