Effects of Axial Flux Magnetic Gear Misalignment
2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020Magnetic gears have recently received significant interest as a potential replacement for mechanical gears. Some papers have proposed that magnetic gears may be more tolerant to misalignment than their mechanical counterparts. This paper describes a parametric finite element analysis (FEA) study of the effects of misalignment in an axial flux magnetic ...

Axial Flux Cycloidal Magnetic Gears
IEEE Transactions on Magnetics, 2014The radial flux cycloid permanent magnet gear is characterized by a high gear ratio and a high torque density due to the use of one air gap. There are at least three disadvantages of this gear: 1) eccentric motion of the output rotor must be transferred to concentric shaft rotation; 2) the bearing loads are very large due to the offset rotor rotation ...

Magnet Gear with Two-Axial Magnetic Paths
Journal of the Korean Society for Precision Engineering, 2014A magnet gear composed of two layers of permanent magnets repeated circumferentially can transmit the power without mechanical contact. In the topology called by the magnet shutter gear known as the most competitive concept among the existing concepts, the number of pole-pairs on the high speed rotor corresponds to that of low speed rotor through ...

Mechanical behavior of axially magnetized permanent-magnet gears
IEEE Transactions on Magnetics, 2001We studied permanent-magnet (PM) gears with axially magnetized permanent magnets and a plane air gap in terms of mechanical behavior. We determined the torque and forces exerted between the two rotors of these devices, using a seminumerical method based on the calculation of the forces between the magnets of the rotors. The study deals with the general

Multi-Objective Optimization of an Axial-Flux Magnetic Gear Using Taguchi Method
The Power Electronics, Drive Systems & Technologies Conference, 2023Torque and speed scaling has always been a challenging issue in industrial facilities. Nowadays, magnetic gears are becoming the proper alternative to their mechanical counterpart due to their inherent advantages. As magnetic gears are scaling the torque,

An Axial-Field Flux-Modulated Magnetic Gear
IEEE Transactions on Applied Superconductivity, 2016This paper proposes an axial-field flux-modulated magnetic gear (AF-FMMG), in which the rotations with different speeds of the inner rotor and the outer rotor can be achieved based on the modulation function of two stationary modulation rings. Due to the axial-flux configuration, the proposed AF-FMMG offers the advantages of a simpler mechanical ...
