Magnetic gearbox for automotive power transmissions: An innovative industrial technology
Engineering Science and Technology, an International Journal, 2023 Conventional coaxial magnetic gears are structures with permanent magnets, which working principle is equivalent to that of epicyclic gearing. The motion is transferred between different axles, without contact in the rotating elements, by modulating the ...

Simulation of a linear permanent magnet vernier machine for direct-drive wave power generation [PDF]
, 2011 This paper proposes a linear permanent magnet (PM) vernier machine for direct-drive wave power generation. Firstly, the machine structure is proposed and its parameters are indentified by finite element analysis (FEA). Secondly, the mathematical modeling

Towards Miniaturization of Magnetic Gears: Torque Performance Assessment
Micromachines, 2017 Magnetomechanical components can be a good solution in order to reduce, or even completely avoid, friction phenomena in micro-electro-mechanical systems (MEMS) since they can transmit forces through magnetic fields without contacts. In this communication,
