Analysis of the Vibration Characteristics of Coaxial Magnetic Gear
IEEE Transactions on Magnetics, 2016This paper investigates the vibration and noise characteristics of the coaxial magnetic gear (CMG) by the electromagnetic forces. In the CMG, the vibration and noise can be generated by the exciting forces acting on three parts, namely, low-speed rotor, high-speed rotor, and modulating pieces, respectively.

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

Analysis and optimization of coaxial magnetic gears
2016 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM), 2016Coaxial magnetic gears with permanent magnets have a very simple structure and performance comparable to that of mechanical gears. The paper describes an analytical simplified approach for the analysis and design procedure. The mathematical model is one-dimensional: only the variation of electromagnetic quantities as function of angular position is ...

Development of a novel Coaxial Magnetic Gear
2017 15th International Conference on Electrical Machines, Drives and Power Systems (ELMA), 2017Magnetic Gears (MGs) offer many advantages compared to mechanical gears such as reduced maintenance, high reliability and inherent over load protection. Among various MGs, a Surface Permanent Magnet (SPM) type Coaxial Magnetic Gear (CMG), which may be accepted to be a classical CMG, is may be preferable owing to its high torque transmission capability.

Harmonic analysis of the magnetic field of a coaxial magnetic gear
2017 15th International Conference on Electrical Machines, Drives and Power Systems (ELMA), 2017In this paper two constructions of a coaxial magnetic gear (CMG) have been investigated. A 2D time dependent Finite Element Method (FEM) models of the two constructions have been implemented. A harmonic analysis of the gears' magnetic fields and output dynamic torques are performed. The FEM modelling is carried out by ANSYS Maxwell software.

Structural Optimization of a Novel Coaxial Magnetic Gear
Advanced Materials Research, 2012Compared with the traditional mechanical gear, permanent magnetic gear has some unique advantages, such as high efficiency, noise free, zero friction, and overload protection and so on. However, its applications are always constrained due to its unstable or not smooth torque produced by this kind of magnetic gear. Based on the structure of the magnetic

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.
