一种自动扶梯用混合励磁电磁铁的设计分析

摘要

本文设计了一款采用电励磁和永磁体励磁并联结构的混合励磁电磁铁，并对其进行了电磁场分析，给出了样机的设计方案和测试结果。%This paper presents a new design of electromagnet, which excited by electricity and permanent magnet both. The structure and the principle of the electromagnet are explored.3D FEM is used to analyze the electromagnet and the result shows in this paper.
