Design and Analysis of Different Structures of Permanent Magnet for Permanent Magnet Linear Synchronous Motors

Fengrui Cui, Zhaolong Sun, Hanning Qian, Wei Min Xu

Abstract

Permanent magnet linear synchronous motor (PMLSM) has a good application prospect in the fields of electromagnetic emission. The finite element method is applied to analyze the magnetic field of PMLSM with different permanent magnet (PM) structures. Then, the thrust characteristic of the PMLSM is optimized by PM cutting and Halbach PM, which promotes the study of permanent magnet structure problems in the design of PMLSM.
