Analysis of coaxial magnetic gears
2015 International Conference on Clean Electrical Power (ICCEP), 2015The behavior of a magnetic gear which employs rare earth magnets is analyzed; the magnetic gear allows the power to be transmitted by transforming speed and torque. An analytical simplified approach for the analysis of the considered magnetic gear is used in this paper. The approach can be suitable for design aims.

Review and Analysis of Coaxial Magnetic Gear Pole Pair Count Selection Effects
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022Magnetic gears perform the same function as mechanical gears using magnetic fields instead of interlocking teeth. A review of the design processes used in the literature demonstrates that a critical design parameter, pole pair count, is often given ...

An optimization tool for coaxial magnetic gears
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2017Purpose 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
