Abstract

This work presents a 2-D electromagnetic field analysis of the single-sided linear induction motor (LIM), taking into account saturation in both primary and secondary cores. An analytical layer model has been developed in which the primary core is modeled by two different layers representing the yoke and teeth-slot regions. Such representation facilitates the evaluation of the magnetic state of the primary yoke and teeth separately. A generalized mathematical formulation of a multilayer model is presented. The analytical computation results from a seven-layer model correlate very well with experimental results obtained from an intermediate-capacity transit system LIM. The model is well suited for sensitivity analysis and design studies.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
