摘　　要：为克服双斜槽感应电机轴向拓扑仿真时需采用低效率高精度的三维有限元仿真的问题,针对错开双斜槽转子感应电机(DSRIM)提出一种等效电路,然后基于多层有限元模型建立DSRIM的轴向分层等效电路。在等效电路与磁场耦合分析的基础上,运用分布磁路法求出气隙磁场分布与稳态性能指标。与试验结果进行对比,对比结果显示该方法的计算结果具有指导意义。To overcome the problem of using low-efficiency and high-precision 3D finite element simulation in axial topology simulation of double skewed induction motor,an equivalent circuit is proposed for the staggered double skewed rotor induction motor(DSRIM)and then the axially layered equivalent circuit of DSRIM is established based on the multi-layer finite element model.Based on the coupling analysis of the equivalent circuit and the magnetic field,the air-gap magnetic field distribution and steady-state performance index are obtained by using the distributed magnetic circuit method.The calculation results are compared with the experimental results,and it is shown that the calculation results of this method have guiding significance.
