Comparison of Coaxial Magnetic Gears With and Without Magnetic Conducting Ring

IEEE Transactions on Applied Superconductivity, 2016
This paper quantitatively compares four coaxial magnetic gears (CMGs) with and without magnetic conducting ring (MCR), which are artfully integrated into a permanent-magnet (PM) machine. In addition, different gear ratios are investigated for both topologies.

Comparison of coaxial magnetic gears with parallel and series magnetic circuits

2016 Eleventh International Conference on Ecological Vehicles and Renewable Energies (EVER), 2016
This paper quantitatively compares two coaxial magnetic gears (CMGs) with parallel magnetic circuit and series magnetic circuit, which are artfully integrated into a permanent magnet (PM) brushless DC motor. By using the finite-element method, the performances of both CMGs are compared and evaluated.

Eddy current losses in permanent magnets of a coaxial magnetic gear

2018 20th International Symposium on Electrical Apparatus and Technologies (SIELA), 2018
In the present work, eddy current losses in permanent magnets of a coaxial magnetic gear construction are estimated. Transient finite element method model is implemented for eddy currents calculation in dynamic operational mode. Simulations in different rotational speeds are performed and results for the eddy currents demagnetization effect over the ...

Study on cogging torque in coaxial planetary magnetic gear

2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC), 2016
In this paper, the cogging torque in coaxial planetary magnetic gear (CPMG) is investigated. The known method for estimation the cogging torque fundamental frequency in permanent magnet synchronous machines is adapted to the double-rotor structure of the CPMG.

Analytical calculation of magnetic field distribution in coaxial magnetic gears

2010
Coaxial magnetic gears are a new breed of magnetic devices, which utilize the interaction of permanent magnet fields to enable torque transmission. Apart from using a numerical approach for their magnetic field analysis, an analytical approach is highly desirable since it can provide an insightful knowledge for design and optimization. In this paper, a
