Analysis and optimal design of the slit type low speed linear induction motor

Abstract

This paper describes the analysis and optimal design of the slit type linear induction motor (LIM) with transformed secondary reaction plate. In an analysis method, we select a unit region corresponding to a single secondary slit pitch and the presence of the rest of the secondary distribution is implied by specifying the pitch boundary condition. From the analysis method, we construct the equivalent circuit and analyze the characteristics of the LIM. Using the sequential quadrature programming (SQP), the optimum design variables are derived. The analysis result by the proposed method is compared with the experimental result.
