本文在传统永磁同步电机定子裂比定义的基础上得出了双定子电机定子裂比的定义,针对这一双定子电机设计的重要参数建模进行了研究,根据求出的最优值设计了一台125 kW的双定子永磁同步电机,并用有限元分析软件进行了仿真验证,为双定子永磁同步电机在有轨电车上的应用提供了一定的理论基础。

Based on the traditional definition of stator split ratio for permanent magnet synchronous motors,this paper proposes a definition of stator split ratio for dual stator motors.The important parameter modeling for the design of this dual stator motor is studied,and a 125 kW dual stator permanent magnet synchronous motor is designed based on the optimal value obtained.Simulation verification is conducted using finite element analysis software,so as to provide a certain theoretical basis for the application of dual stator permanent magnet synchronous motors on trams.
