Performance analysis of the moving primary six-phase linear induction motor

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.
