Abstract：In order to improve the performance of linear induction motor,considering the transverse and longitudinal edge effect,an equivalent circuit of cap linear motoris established.After the determination of the cap secondary optimization variables,the analytical expression and the multi objective optimal function of the thrust,efficiency,power factor and secondary weight per unit length are obtained.Under the constraint of the secondary width,the optimal calculation of thrust,efficiency,power factor and equal weight per unit is realized by genetic algorithm.The 3D FEM (finite element model) is established for the composite secondary and cap secondary.The comparative results between the analytical expression and FE simulation prove the applicable of the optimization methods.
