Towards Miniaturization of Magnetic Gears: Torque Performance Assessment [PDF]
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,

Magnetically Geared Induction Machines [PDF]
IEEE Transactions on Magnetics, 2015 A wound-rotor induction machine is artfully coupled to a magnetic gear to achieve a high-torque-density drive system called magnetically geared induction machine (MaGIM). The high-speed rotor of MaGIM is common to both the machine and gear sides. A rotating diode rectifier electrically links the machine's wound rotor and a dc boost winding on the gear ...

Rotary-to-Linear Magnetic Gear
IEEE Transactions on Industry Applications, 2023 The paper introduces a permanent magnet rotary-to-linear magnetic gear whose topology is derived based on the operating principle of a transverse flux VRPM machine. It is shown that when the number of poles per unit length on all three members, rotor, translator and stationary flux modulating ferromagnetic pieces, are the same, the proposed gear is ...

Magnetic Loss Analysis in Coaxial Magnetic Gears [PDF]
Electronics, 2019 This paper proposes a procedure for computing magnetic losses in coaxial magnetic gears. These magnetic structures are made of permanent magnets and ferromagnetic poles in relative motion transferring torque between two shafts in a contactless way. The loss computation in magnetic materials is crucial to define the system performance.
