Vibration and Noise Analysis of a Coaxial Magnetic Gear
2019 II International Conference on High Technology for Sustainable Development (HiTech), 2019In the present work are estimated vibration and noise spectrums of a coaxial magnetic gear under no-load operational conditions. The developed approach is used to incorporate three different types of vibration analyzes: random vibration, response spectrum and harmonic response analyzes, based on modal analysis results. Finite element method modeling is

Comparison of Coaxial Magnetic Gears With and Without Magnetic Conducting Ring
IEEE Transactions on Applied Superconductivity, 2016This 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 Radial Force at Modulating Pieces in Coaxial Magnetic Gear and Magnetic Geared Machine
IEEE Transactions on Magnetics, 2018Unlike the coaxial magnetic gear (CMG), the magnetic geared machine (MGM) has the ac armature winding on the inner part or the outer part. Besides, the PM excitation field of the CMG and the ac armature field of the MGM have different space harmonic components of magnetic field from one other.
