摘要：针对基于三相异步电动机物理模型的数学模型分析十分复杂的问题，通过将三相异步电动机数学模型转换到d-q坐标系，利用单相异步电动机的双旋转磁场分析法，并利用二相电机的物理模型和等效电路模型，对三相异步电动机机械特性等进行了研究，推导出了基于二相模型的三相电机的机械特性方程。实验结果证明了该方法的可行性。

Abstract: Aiming at the problem that it is complicated to analyze mathematical model of threephase asynchronous motor based on physical model. The mathematical model of threephase induction motor was transformed to d-q coordinates, the mechanical characteristics based on physical model and circuit model of twophase motor, and doublerevolving field theory were studied. The mechanical characteristics equation of threephase induction motor was derived. The results indicate that this method is feasible.
