| 摘 要： | 针对二维有限元和磁链法计算无轴承开关磁阻电机(Bearingless switched reluctance motor,BSRM)电感特性的局限性,建立了BSRM稳定悬浮时的三维有限元模型,采用双标量磁位法计算得到其磁场分布,应用一种仅需计算非线性系统能量增量即可计算电感的增强型能量增量法,计算其绕组电感.以-7.5 kW,12/8结构的BSRM为例,简单比较了双标量磁位法与二维有限元法、矢量磁位法和棱边有限元法分别求解BSRM磁场时的计算规模和平均计算时间,说明了双标量磁位法在大规模计算场合的优越性;研究了电感与转子径向位移的关系;计算获得了样机处于稳定悬浮状态下的主、悬浮绕组电感;研究了端部效应对电机磁场分布和绕组电感的影响.通过实验验证了电感计算的准确性,为优化设计和精确控制该类电机奠定了基础.

| Abstract: | Due to inductance computation limitations using 2D finite element method(FEM) and flux linkage method for the bearingless switched reluctance motor(BSRM),3D distributions of a magnetic field for a BSRM under the condition of steady magnetic suspension are obtained by the double scalar magnetic potential method(DSMP),and then static inductances of main-and suspended windings are calculated with the enhanced incremental energy method(EIEM) only needing the nonlinear incremental energy computed.For a 7.5 kW 12... |
