摘要
对大型复杂结构的十五相感应电机进行了三维有限元时谐电磁场分析计算。建立了精准的三维有限元电机模型,给出了定转子电流密度、整个矢量磁密分布,对其进行了分析说明,获得了气隙径向磁通密度结果,并进行了谐波分析。三维有限元电磁场计算可得到精确的电磁场分布及电机性能参数,对新型结构多相电机研制能给出依据,在结构优化设计方面也能起到借鉴作用。
Three-dimensional finite element analysis of harmonic electromagnetic field in a large and complex structure 15-phase induction machine had been completed. Accurate 3D finite element machine model was established. The current density of stator and rotor, and the entire vector flux density distribution were given, then analyzed and explained. The air gap radial flux density was obtained and had been made harmonic analysis. We can obtain the accurate electromagnetic field distribution and performance parameters through 3D finite element calculation of electromagnetic field. This method can give the basis for the muhiphase machine development of new structure and can play reference in terms of structural optimization design.
