| 摘 要： | 针对磁悬浮开关磁阻电机运行过程中容易出现磁饱和及转子偏心的问题,建立了一种新型的一体化数学模型.首先,依据电机磁场的有限元分析结果,基于麦克斯韦张量法求出了径向力及转矩关于气隙磁密的表达式.其次,根据电机的等效磁路,结合铁芯材料的磁化特性,计算了非线性气隙磁密.最后,以此二者为基础建立了磁悬浮开关磁阻电机的一体化数学模...

| Abstract: | In light of magnetic saturation and radial displacements in bearingless switched reluctance motors(BSRM),a novel integrative mathematical model was proposed.Based on the finite element analysis of motor magnetic field,the radial force and torque expressions about gas magnetic densities were obtained by Maxwell stress tensor method.The nonlinear gas magnetic densities were calculated based on single equivalent magnetic circuit combined with the nonlinear magnetization characteristic of iron core.At last,the ... |
