摘　　要：针对永磁直流电动机的特点,结合电机CAD技术,开发了永磁直流电动机CAD系统。系统采用有限元分析软件Ansys完成电机电磁场的数值分析,采用数据库对设计方案及材料参数进行管理,计算准确可靠,功能完善实用,具有较好的工程应用前景。According to the character of the permanent magnet direct current motor, the permanent magnet direct current motor computer aid design system was developed. The electromagnetic fields of the motor was analyzed by applying the finite element method software-ansys. The design projects and the parameters of material were managed by applying databases. The system which has practical functions can yield more accurate and reliable design solutions than the traditional method. As a powerful tool for designer of electric motor, it has wide application prospects in engineering.
