Characteristic of double gap SLIM under constant current excitation

Abstract

A single-sided linear induction motor (SLIM) may have double clearance under certain practical conditions. In order to evaluate the effects of double air-gaps five-layer Fourier transform model of SLIM has been developed and its performance has been predicted in Fourier-space using Parseval's theorem. The validation of developed model has been done using FEM code 'ANSYS 5.0' and experimental results. The effects of additional gap on thrust and normal force have been investigated. © 2003 Elsevier Science Ltd. All rights reserved.
