摘　　要：为了准确刻画对象模型,采用一阶等效电路瞬态涡流分析法对动态边端效应影响下动初级高速六相直线感应电机的参数时变规律进行了定量计算,并通过感应涡流损耗推导得到考虑动态边端效应时电机的等效电路。基于此,通过电磁推力计算及效率评估对动态边端效应影响下电机的工作特性进行了详细分析。利用不同运行速度条件下的有限元仿真及动态实验验证了理论分析和推导的正确性。In order to accurately describe the object model,the first-order equivalent circuit transient eddy current analysis method was used to quantitatively calculate the parameter time-varying rule of the moving primary high-speed six-phase linear induction motor under the influence of the dynamic end effect,and the equivalent circuit of the motor was deduced considering the dynamic end effect through the deduce of the induction eddy current loss.On this basis,the performance characteristics of the motor under the influence of the dynamic end effect were analyzed in detail through the calculation of electromagnetic thrust and efficiency evaluation.The correctness of the theoretical analysis and the accuracy of the motor model were verified by the finite element simulation and dynamic experiment under different operating speeds.
