摘　　要：传统磁力联轴器的性能依赖于稀土材料,其结构对永磁材料的利用率不高,难以进一步优化。文中改变了磁力联轴器的磁极结构,于内外转子均采用永磁极与铁芯极交替排布,提出一种双交替极径向同步磁力联轴器;通过有限元分析,对比验证了交替极结构与传统结构联轴器的气隙磁密、磁场分布和转矩性能。通过验证得到,在保证材料用量的前提下,交替极联轴器性能更好、材料利用率优化空间更大。The performance of traditional magnetic couplings depends on rare earth materials and its structure of the permanent magnet materials is not highly efficient and difficult to further optimize. This paper changes the magnetic pole structure of the magnetic coupling. The permanent magnetic poles and the iron core poles are alternately arranged in both the inner and outer rotors, and a double alternating-pole radial synchronous magnetic coupling is proposed. The air gap magnetic density, magnetic field distribution and torque performance of the alternating pole structure and the traditional structure coupling are verified by finite element analysis and comparison. The result shows that under the premise of ensuring the amount of material, the alternating pole coupling has better performance and more room for optimization of material utilization.
