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 ...

Modeling of Dynamic Torque Control of a Coaxial Magnetic Gear

2019 22nd International Conference on the Computation of Electromagnetic Fields (COMPUMAG), 2019
Overload of magnetic gears effects in output rotor slipping which reduce its speed and torque. Here is presented a dynamic model of a control system to avoid overload and keep optimal power transmission between rotors of a coaxial magnetic gear. The dynamic control model couples transient finite element magnetic model, kinematic losses model, to keep ...

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
