摘　　要：采用有限元法分析了内嵌式变频永磁同步电动机转子永磁体各尺寸对电机气隙磁密和静动态特性及性能影响,研究了矩形和V形两种永磁体结构转子的永久磁极各尺寸选择依据和范围,利用分析结果分别设计了矩形和V形永磁体转子两种内嵌式永磁同步电动机。针对所设计的矩形永磁体转子内嵌式变频永磁同步电动机的交直轴电感参数和永磁体磁链值进行了有限元计算,对电机参数的实验测试结果证明了理论分析的正确性,分析结果为内嵌式变频永磁同步电机的设计和参数计算提供了理论依据。In this paper,by using finite element analysis,the effects of various dimensions of rotor permanent magnets of the embedded variable-frequency permanent magnet synchronous motor on the magnetic flux density,the static/dynamic characteristics,and the performance of the motor were analyzed;the design principles and dimension ranges of the permanent magnetic pole dimensions of the two permanent magnet rotors with rectangular and V-shaped permanent magnets were investigated.On the basis of the analysis results,a rectangular-shaped permanent magnet motor and a V-shaped permanent magnet motor were designed.The d axis inductance,q axis inductance,and permanent magnet flux were calculated through finite element analysis.An experiment was conducted to test the parameters of the motors,and the results validated the theoretical analysis.This paper provides a theoretical basis for the design and parameter calculation of the embedded variable-frequency permanent magnet synchronous motor.
