Abstract

This paper investigates the performance of a -25:1 gear ratio cycloidal magnetic gearbox (CMG) with a flux-focusing rotor topology. The performance of the CMG is investigated by conducting an iterative parameter sweep analysis. An active region torque density of 291 Nm/L is calculated to be achievable with a 0.46% torque ripple. The cycloidal gearbox operates utilizing a nonuniform rotor air gap and this has the adverse effect of creating large nonsymmetric radial forces.
