本文分析了一种1：4.25比例的铁氧体磁体和钕铁硼磁体的高极数磁通聚焦磁齿轮箱。一个简单的参数扫描分析表明，高于以前公布的扭矩密度值是可以实现的。实验结果，然后提出的钕铁硼设计，确认的计算，也表明，建议的磁齿轮箱可以运行的低转矩涟漪。
In this paper a 1:4.25 ratio ferrite magnet and NdFeB magnet flux-focusing magnetic gearbox with a high pole count is analyzed. A simple parameter sweep analysis is used to show that higher than previously published torque density values are achievable. Experimental results are then presented for the NdFeB design that confirm the calculations and also demonstrate that the proposed magnetic gearbox can operate with a low torque ripple.
