Coaxial Magnetic Gear Design and Optimization
IEEE Transactions on Industrial Electronics, 2017The main aim of this paper is the imposition of constraints for the multiobjective optimizations of magnetic gears. In order to reduce the computational effort, a semianalytic design procedure is adopted, providing a fast simulation tool that can be embedded within an optimization loop.

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.

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

3D Modelling of a Coaxial Magnetic Gear
2019 11th Electrical Engineering Faculty Conference (BulEF), 2019In this paper a 3D model of a coaxial magnetic gear has been developed. Typically, magnetic gears are considered as a 2D plane-parallel models. In such models, the edge effects on magnetic field distributions in the forehead of the construction are not estimated where magnetic reluctance is significant especially for shorter length designs.

Eddy Current Losses of Coaxial Magnetic Gears
2018 XIII International Conference on Electrical Machines (ICEM), 2018Reduction of eddy current losses is essential for magnetic gears efficiency enhancement. These losses are resulting in output torque reduction, especially in high rotational speeds and high gear ratios. In this paper, we developed an approach for determination of the eddy current losses of a coaxial magnetic gear.
