摘　　要：以1台三相、12/8极、3kW开关磁阻电机(SRM)为样机,在电机电磁场基础理论及条件假设的基础上,建立场-路耦合的电机电磁场计算模型,利用时步有限元法对电机工作在额定负载工况下的运行情况进行仿真和数值求解,进一步分析电机气隙磁密的分布情况和谐波含量,并对电机定、转子铁心磁密进行研究。在此基础上,通过将电机铁心分段,分析额定负载状态下电机不同铁心段的铁心损耗,并得出一些有益的结论。In this paper,a three-phase,12/8pole,3kW switch reluctance motor（SRM）is selected as the prototype,based on the fundamental theory of electromagnetic field and the assumed conditions.The calculating model of electromagnetic field with field-road coupled,time-step finite element method is used to simulate and calculate under rated load working conditions.Both the distribution of gap flux density and harmonic content are analyzed in-depth,moreover,the core flux density of stator and rotor are calculated and analyzed.Based on this,with cores segmented,the core loss of each segment under rated load condition is calculated and some valuable conclusions can be drawn in the end.
