Abstract

In this paper, a 1:4.25 ratio ferrite magnet and Nd-Fe-B 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 Nd-Fe-B design that confirm the calculations and also demonstrate that the proposed magnetic gearbox can operate with a low torque ripple.
