A High Torque Density Halbach Rotor Coaxial Magnetic Gear

2019 IEEE International Electric Machines & Drives Conference (IEMDC), 2019
This paper presents the design, analysis, and experimental testing results for a 5.67:1 Halbach rotor magnetic gearbox with a ferromagnetic back support. Using 3-D finite element analysis software the Halbach magnetic gearbox was calculated to achieve a volumetric torque density of 284N.m/L with only an active region outer diameter of 120mm.
