摘　　要：采用子域法对表贴式永磁同步电机(SPMSM)进行建模,对电机内部磁场进行解析计算。针对传统子域法无法应用于采用偏心削极结构的SPMSM的问题,对不等厚偏心削极的永磁体子域,提出等面积分块的处理方式,将每个磁极块单独进行解析计算。将线性叠加结果与有限元法和实验结果进行对比,结果表明所提方法有较高的计算精度。此外,将不同种类电机及子域建模方法进行整合,建立用户交互平台,使计算过程可视化,为国产化工程应用软件提供可扩展性,辅助电机设计与分析工作。Subdomain analytical method is used to model a surface-mounted permanent magnet synchronous motor(SPMSM),and the internal magnetic field of the motor is analytically calculated.Aiming at the problem that the traditional subdomain method cannot be directly applied to SPMSM with eccentrically clipped poles,an equal-area block processing method is proposed for permanent magnet subdomains with unequal thicknesses of eccentrically clipped poles,and each pole block is analyzed separately.The linear superposition and summation results are compared with the finite element method and experimental results.The results show that the proposed method having high calculation accuracy.In addition,different types of motors and subdomain modeling methods are integrated to establish a user interactive platform to visualize the numerical calculation process,further providing scalability for domestically produced engineering application software and assisting motor design and analysis work.
