摘要

本文在传统表面贴装式直线永磁电机(SM-LPMM)的基础上,提出了一种改进的t型直线永磁电机(T-LPMM)。所提出的拓扑结构旨在保护永磁体表面免受腐蚀,并提高其抗高频振动的刚度。首先,考虑插入式t形结构,在MATLAB中采用自动脚本的有限元法对无槽磁场进行预测;然后,采用Schwarz-Christoffel (SC)映射计算槽效应。然后,建立子域(SD)模型分析电枢反应,并采用田口法进行优化。通过有限元分析对优化结果进行了验证,并与T-LPMM和SM-LPMM进行了对比试验。实验证明了所提出的T-LPMM具有优异的电磁输出性能。

Design and Optimization of an Improved T-shape Linear Permanent Magnet Machines
This paper presents an improved T-shape linear permanent magnet machine (T-LPMM) based on a traditional surface-mounted linear permanent magnet machine (SM-LPMM). The proposed topological structure aims to protect the surface of the permanent magnet from corrosion and enhance the rigidity against make highfrequency vibration. Firstly, the slotless magnetic field is predicted using finite-element method (FEM) with automatic scripting in MATLAB to consider the inset T-shape structure of PM. Then, the Schwarz-Christoffel (SC) mapping is adopted to calculate the slot effect. Afterward, a subdomain (SD) model is established to analyze the armature reaction, and Taguchi method is employed for optimization purposes. The optimized result is verified by FEM, and a comparison experiment is conducted between T-LPMM and SM-LPMM. The experimental demonstrate superior electromagnetic output performance of the proposed T-LPMM.
