Performance Potential of High Gear Ratio Coaxial Magnetic Gears
2021 IEEE International Magnetic Conference (INTERMAG), 2021It 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.

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.

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.

A Coaxial Magnetic Gear With Consequent-Pole Rotors
IEEE Transactions on Energy Conversion, 2017In this paper, a novel coaxial magnetic gear (MG) is proposed, in which both permanent magnet and consequent poles are employed on the inner and outer rotors. The MG is expected with improved torque transmission capability by increasing the effective magnetic flux and offering additional reluctance torque.

Dynamic model of coaxial magnetic planetary gear
2015 18th International Conference on Electrical Machines and Systems (ICEMS), 2015This paper presents equations, describing the dynamic behavior of a coaxial magnetic planetary gear and its implementation in a Matlab/Simulink model. Parameters of speed oscillations caused by a disturbance of the drive torque are studied. The paper also includes simplified formulas for calculation an eigenfrequency and damping parameters of the ...

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.
