An Equivalent Circuit for the Single-sided Linear Induction Motor Secondary Width optimization

Abstract

There are some problems with regard to the optimization of the secondary width of the single-sided linear induction motor used in subway, such as the large amount of calculation and takes a long time. Firstly, an equivalent circuit for secondary width optimization is proposed. Based on the energy conversion relationship, the formulas for calculating thrust and efficiency related to secondary width are derived. Then, the finite element simulation of different secondary widths is carried out, and the optimal widths in the range are found out by comparing with the analytical results. Finally, the linear induction motor experimental platform is used to verify the correctness of the equivalent circuit.
