Performance Potential of High Gear Ratio Coaxial Magnetic Gears
2021 IEEE International Magnetic Conference (INTERMAG), 2021 It has been traditionally thought that a coaxial magnetic gear (MG) can only have a high volumetric torque density at a low gear ratio. This paper points out that by using the right sized radius and utilizing judicious radial parameter sweep analysis a high torque density can be created that also operates with a high gear ratio.

An optimization tool for coaxial magnetic gears
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2017 Purpose This paper aims to show a complete optimization tool that can be used for the design of coaxial magnetic gears. In the first part, the paper deals with the semi-analytic modelling of these machines and also discusses how to reduce the computational efforts. In the second part, an optimization algorithm is adopted for finding the Pareto optimal
