摘　　要：以一台凸极同步电动机为例,给出了基本假设和边界条件,利用正弦时变场原理和有限元法,并以端电压和磁感应强度为收敛条件,对凸极同步电动机起动时的电磁场和定子绕组的电流进行了分析和计算,并与实测结果进行对比。分析研究了起动时凸极同步电动机磁场的分布和谐波。In this paper a salient pole synchronous motor is taken as an example, the basic hypothesis and boundary condition are given, by using sinusoidal transient field theory and finite element method, the starting electromagnetic field of the salient pole synchronous motor and the current in the stator windings are analyzed and calculated when the end voltage and the flux density are taken as convergent condition and compared with the actual results. By analyzing and studying magnetic field distribution and harmonic wave when the salient pole synchronous motor starting, some useful conclusions are gotten.
