英文摘要：

The largest longitudinal edge effect of motor performance was introduced in this paper, the negative effect was obtained by the electromagnetic field analysis, and the equivalent factor was gotten by using electrical potential induced by effective primary winding. The longitudinal edge effect was used into the equivalent circuit, the motor characteristic through equivalent circuit considering edge effect are computed. Finally, the thrust, normal force, subpower factor and efficiency were discussed under different air gap and supply power frequency. The work in this paper provides important method and evidence for the characteristic analysis of linear induction traction motor and rail transit application.
