摘要 针对传统的4极6槽双边对称长初级永磁直线同步电机,在保证电磁推力大小的情况下,提出采用双边错位来降低永磁体涡流损耗的有效方法。介绍电机的基本结构,阐明双边错位结构可以完全消除偶数次电枢谐波磁动势,进而能大幅度降低次级永磁体涡流损耗。利用有限元分析(FEA)软件对比分析对称结构和错位结构的定位力、电磁推力和次级涡流损耗,验证错位方法的正确性,并进行结构优化设计。最后,研制一台样机并搭建实验平台,测得样机的空载反电动势、定位力以及静推力。

Abstract:As for the traditional 4-pole 6-slot double-sided symmetrical long primary permanent magnet linear synchronous motor, under the condition of ensuring the electromagnetic thrust, an effective method to reduce the permanent magnet eddy current loss was proposed by adopting bilateral dislocation. The basic structure of the motor was introduced. The double-sided dislocation structure could completely eliminate the even number of armature harmonic magnetomotive force, thereby greatly reducing the permanent magnet eddy current loss. The finite element analysis (FEA) software was adopted to analyze the detent forces of symmetric and dislocation structures, the electromagnetic thrust and the secondary eddy current losses. The accuracy of the dislocation method was proved and the structure was optimized. At last, a prototype was developed, and its back-electromotive force (back-EMF), detent force and static thrust were measured through an experimental platform.
