Experimentally Testing a Halbach Rotor Coaxial Magnetic Gear With 279 Nm/L Torque Density

This paper presents the practical design, analysis, and experimental testing results and encountered issues for a 5.67:1 Halbach rotor magnetic gear with a ferromagnetic back support. Testing results for both a Halbach rotor magnetic gear with rectangular modulation supports and a bridgeless circular modulation support rod design is evaluated. The presented magnetic gear design is shown to be capable of operating with a peak torque of 189 Nm and an active region torque density of 279.3 Nm/L.
