Design of high-speed linear induction motors– part I: electromagnetic modelling
This paper presents an analytical methodology to obtain the magnetic field distribution and calculate the performance of single-sided linear induction machines (SLIMs). The methodology uses a permeance function to estimate the magnetic field in the gap, Fourier analysis to calculate the travelling harmonics and transfer matrices to solve the diffusion equation in a multi-layer model of the rotor. Key performance parameters such as thrust, losses and efficiency are readily calculated using the proposed methodology. Furthermore, the proposed methodology can be generalized for double-sided LIMs (DLIMs) and for machines with multi-material reaction plates. The methodology is applied to a case study of a SLIM for high-speed transportation, presents results and provides an insight into the end effect, the reduction of thrust as the speed increases.

Abstract
This paper presents an analytical methodology to obtain the magnetic field distribution and calculate the performance of single-sided linear induction machines (SLIMs). The methodology uses a permeance function to estimate the magnetic field in the gap, Fourier analysis to calculate the travelling harmonics and transfer matrices to solve the diffusion equation in a multi-layer model of the rotor. Key performance parameters such as thrust, losses and efficiency are readily calculated using the proposed methodology. Furthermore, the proposed methodology can be generalized for double-sided LIMs (DLIMs) and for machines with multi-material reaction plates. The methodology is applied to a case study of a SLIM for high-speed transportation, presents results and provides an insight into the end effect, the reduction of thrust as the speed increases.
