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,

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.

COMPARISON OF MAGNETIC-GEARED PERMANENT-MAGNET MACHINES [PDF]
Progress In Electromagnetics Research, 2013 With the advent of magnetic gears, researchers have developed a new breed of permanent-magnet machines. These magnetic-geared permanent-magnet machines artfully incorporate the concept of magnetic gearing into the permanent-magnet machines, leading to achieve low-speed high-torque direct-drive operation.
