为了更形象地说明交流电机定子旋转磁场的形成机理,基于复平面建立单元交流电机的时空统一矢量方程,详细讲解交流电机旋转矢量的数学推导过程,解析电压、电流及磁链等旋转矢量的物理意义,并以异步电动机和永磁同步电机为例,利用基于复平面的交流电机旋转矢量方程深入浅出地讲解交流电机的工作原理.%In order to illustrate the formation mechanism of the magnetic field of the rotating stators for AC-motors, the time-space unified rotation vector equations are proposed based on the complex plane in this paper. The mathematical derivation process of the rotating-vectors for the AC-motors such as voltage, current and flux linkage is analyzed in detail, and the physical significance of the rotating vectors is explained. Using the proposed rotating vector equations for the induction motor and the permanent magnet synchronous motor as examples, the working principle of the AC motors can be illustrated in simpler but more comprehensible ways.
