摘　　要：本文结合Ansoft Maxwell软件,对永磁有刷直流电机主要参数进行计算,从而确定电机定转子结构参数和绕组参数。利用Ansoft Maxwell中的RMxprt模块对电机进行结构设计和性能分析,得到转速和输入电流、空载下气隙磁通波形等之间的关系。根据RMxprt的设计数据可以在Maxwell 2D模块中生成模型,可以对磁场进行进一步的有限元分析,得到磁通密度云图,磁密矢量图。Combining with Ansoft Maxwell Solftware, this paper calculates the main parameters of Permanent magnet brush DC motor, then determines the structure parameters and winding parameters of motor stator and rotor. Then structure design and performance analysis of the motor are performed by using the RMxprt module in Ansoft Maxwell, which obtains the relationship among the rotational speed, the input current and the Air-Gap Flux Density under no- lood. According to the RMxprt design data, the Maxwell 2D module can generate modules and carry out a further finite element analysis for magnetic flux density map and flux vector diagram.
