Cogging Torque Analysis of Magnetic Gear
IEEE Transactions on Industrial Electronics, 2012This paper describes the harmonic spectra of the cogging torque of a magnetic gear. The operating principle of this gear is described, and the transmission torque under operation in accordance with the gear ratio is mathematically formulated. In particular, the harmonic order of the cogging torque is described in detail.

2014 11th IEEE/IAS International Conference on Industry Applications, 2014
This paper aims to present the operation principle of the magnetic gear by the finite-element method (FEM). The effect of the modulation phenomena is explained using the Coaxial Magnetic Gear as reference. The approach consists basically in obtaining the flux densities waves for the machine air gaps and then analyzes its harmonic spectra. Additionally,

Permanent magnets for a magnetic gear
2016 19th International Symposium on Electrical Apparatus and Technologies (SIELA), 2016A research of the permanent magnet influence on the steady-state and the dynamic characteristics of a magnetic gear is carried out. For this purpose, a two dimensional finite element model has been developed and applied using Ansys Maxwell package. Permanent magnets such as Alnico, ferrite, SmCo and NdFeB are utilized in order to evaluate their effect ...

VII.High-Efficiency Magnetic Gear and Developing Magnetic-Geared Motor
2016 International Conference of Asian Union of Magnetics Societies (ICAUMS), 2016Magnetic gears can transmit torque without any mechanical contacts. Hence, they have low vibration, no wear and fatigue, which offer maintenance-free operation. Various kinds of magnetic gears have been introduced in previous papers and patents. Among them, a flux-modulated type magnetic gear, which consists of an inner and outer rotor with surface ...

A Magnetic-Geared Machine Derived from the Dual-Flux-Modulated Magnetic Gear
2019 International Conference on Artificial Intelligence and Advanced Manufacturing (AIAM), 2019A dual-flux-modulated CMG (DFM-CMG) evolved from the conventional CMG is presented. The torque capability of the DFM-CMG is higher than that of the conventional CMG. A DFM magnetic-geared machine (DFM-MGM) derived from the DFM-CMG is also proposed, which is obtained by replacing the high-speed rotor (HSR) of the DFM-CMG with a stator.
