Abstract: In this paper, in order to shorten the development cycle of permanent magnet synchronous motor, reduce unnecessary human error, provide technical parameters, facilitate adjustment and verification programs, a PMSM CAD system with good manmachine interface and comprehensive features was developed. This paper studied the electromagnetic design process of PMSM and secondary development works of Ansoft Maxwell. A seamless connection achieved between VB and Ansoft Maxwell, by using VB as development tools of interface and database as connection point. The system supports input of design parameters of PMSM, can automatically read data, modeling, analysis, and export results. The system is a powerful auxiliary tool for motor designer, has a good prospect of engineering application.
