Abstract

This paper presents an analytical analysis of magnetic field in a slotless-type permanent magnet linear synchronous machine (PMLSM). For the verification, the numerical analysis (finite element method (FEM)) of magnetic field is accomplished and comparison between analytical and numerical solution of magnetic field is presented. Both analytical and numerical solutions are obtained by 2D analysis via magnetic vector potential, respectively. The paper also presents the comparison between analytical and numerical (FEM) solution of static thrust and normal force using Maxwell's stress tensor method. The verifications show that good agreement between analytical and numerical solution of magnetic field, static thrust and normal force is obtained.
