Magnetic Loss Analysis in Coaxial Magnetic Gears [PDF]
Electronics (Switzerland), 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.

THE DEVELOPMENT OF MAGNETIC GEARS FOR TRANSPORTATION APPLICATIONS [PDF]
Mobility and Vehicle Mechanics, 2017 The gears, where the power and torque transmissions are performed with no contact and with help of the magnetic forces, are called magnetic gears. With this gears, unlike the mechanical gear transmissions, there are no noise, vibrations and friction, so therefore, there is no need for lubrication and maintenance costs are considerably lower.

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 ...
