Abstract: According to the embedded control weak magnetic control characteristics of permanent magnet synchronous motor, with weak magnetic speed ratio as the optimization goal, and using finite element simulation software, embedded speed permanent magnet synchronous motor was analyzed rectangle and V the size and position of permanent magnet motor parameters and the influence of the speed range, through optimizing the position and size of the permanent magnet motor weak magnetic speed range had expanded.The parameters of the optimized motor were calculated, and the range of motor speed before and after optimization was compared.It provided a certain basis for the optimization and parameter calculation of the built-in speed-regulating permanent magnet synchronous motor.

Key words: built-in speed-regulating permanent magnet synchronous motor, permanent magnet size, speed regulating range, finite element analysis
