磁性齿轮正变得越来越有吸引力，因为它们提供的优势，如低振动和噪音，和低维护操作相比，传统的机械齿轮。特别是行星式磁力齿轮，比其他类型的齿轮具有更大的传递扭矩。因此，行星式磁力齿轮有望投入实际应用。本文首先利用有限元分析方法计算了表面贴装永磁行星式磁力齿轮的转矩特性和效率。最后，给出了基于有限元分析结果制造的电磁齿轮样机的实验结果。最后，基于有限元分析和实验结果，验证了原型齿轮的效率提高。改进后的原型齿轮效率达到90%以上。
Magnetic gears are becoming attractive since they offer advantages such as low vibration and acoustic noise, and low maintenance operation in comparison with conventional mechanical gears. Planetary type magnetic gears, especially, have larger transmission torque than the other types. Therefore, the planetary type magnetic gears are expected to be put into practical use. In this paper, first, torque characteristics and efficiency of a planetary type magnetic gear with surface-mounted permanent magnet (SPM) are calculated by finite element analysis (FEA). Next, experimental results of a prototype magnetic gear manufactured on the basis of the FEA results are indicated. Finally, efficiency improvement of the prototype gear is demonstrated based on the FEA and experimental results. The improved prototype gear has achieved high efficiency of over 90%.
