| 摘 要： | 为了兼顾准确性与计算时间,采用解析法和有限元法结合研究槽口宽度对内置式永磁电机齿槽转矩的影响.解析法确定了对齿槽转矩有影响的气隙磁导平方的傅里叶分解次数,采用有限元法计算槽口宽度变化对该傅里叶分解次数的影响.计算表明,该傅里叶分解次数与齿槽转矩的幅值随槽口宽度有相同的变化规律,能够减小该气隙磁导平方的傅里叶分解次数的槽...

| Abstract: | In order to ensure the accuracy and reduce the calculation time,the analytical method and finite element method are applied to study the effect of slot opening on the cogging torque of interior permanent magnet motor.The analytical method was adopted to find the Fourier coefficients which have effect on the cogging torque,and the finite element method was used to study the effect of slot opening on these Fourier coefficients.It was found the effects of slot opening on the cogging torque and the Fourier coef... |
