基于Maxwell 14的外转子电励磁双凸极电机研究

摘要

基于Ansoft Maxwell 2D的仿真环境,建立外转子电励磁双凸极电机(DSEM)的仿真模型.对模型进行瞬态磁场仿真,研究电动机的空载特性和负载特性,获得电动机在不同转子位置角度时的磁场分布、电枢和励磁绕组磁链以及电磁转矩曲线等数据.这些数据为电动汽车驱动系统用电机的设计和优化提供了一些参考.%This paper introduced a simulation model of Doubly Salient Electro-magnetic Motor (DSEM) with external rotor based on the simulation environment of Ansoft Maxwell 2D, The non-load characteristics and load characteristics of motor were researched by the transient magnetic field simulation. The magnetic field distribution, magnetic chain of the armature and field windings and electromagnetic torque curves in different rotor position angle were obtained. These data provided some reference for motor drive system's design and optimization for electric cars.
