摘要
采用场路结合的方法，建立和求解了二维涡流场方程——定子电压方程的耦合有限元方程。并借助于电路分析，计算实心转子永磁同步电动机起动过程中的动态转子参数，同时用端部系数计入端部效应的影响，从而获得转子参数随滑差ｓ的变化曲线。在此基础上建立永磁同步电动机起动过程的计算机仿真数学模型，用龙格—库塔法解之，便可得到各种动态特性。此法可用于研究电机的起动特性、分析电机参数和永久磁钢特性对电机起动性能的影响，进而可改进电机的设计。
With combined field and circuit method, the
paper presents and solves the finite equations coupling eddy field and stator voltage. The
dynamic rotor parameters of solid rotor PM synchronous motor is calculated. By employing the
factor of motor end, the end effect is considered in the curves of dynamic rotor parameter.
Besides, a simulation mathematics model is established. It could be easily used to determine
the starting behavior of the motor and the roles of each parameter acting. Thus it will be a great
help in motor improvement and design.
