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。
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.
