Abstract

This paper presents characteristics of a permanent magnet linear synchronous motor (PMLSM) considering lateral leakage flux and lateral displacement. In order to analyze the PMLSM with large air gap and finite width, a new three dimensional equivalent magnetic circuit network method (3D EMC) is introduced, which supplements the magnetic equivalent circuit by using numerical techniques. It can model flux ripple three-dimensionally by the teeth and slot structure of the PMLSM, and can take nonlinear magnetic phenomenon into account, which results from using the distributed magnetic circuit parameter, permeance. The analysis considering lateral flux and lateral displacement in the PMLSM which is problematic in 3D is performed using 3D EMC and is compared with the experimental value
