CAD System for Permanent Magnet Synchronous Motors with External Rotors

讨论了外转子永磁同步电动机与内转子永磁电机结构的不同之处,介绍了外转子永磁同步电动机转子轭磁压降、计算极弧系数的计算方法。并在此基础上采用可视化的编程工具C++Builder 6.0设计开发了基于Windows的外转子永磁同步电动机计算机辅助系统,通过设计实例,将该CAD系统设计结果与已有的CAD系统设计结果进行了比较,证明了该CAD系统的可靠性和准确性。

This paper discussed the differences between external rotor permanent magnet synchronous motors（ ERPMSWs） and conventional motors, and proposed methods to calculate the parameters of permanent magnet synchronous motors with external rotors, such as the rotor yoke voltage drop, calculating arc coeffieiency. A computer aided design （ CAD ） system using C ＋＋ Builder 6.0 was developed based on Windows. With an example, the CAD system design results and predecessors design CAD system design results were compared. The results verify the reliability and practicality of the CAD system.
