Magnetic Levitating Gear

Researchers from Universidad Carlos III de Madrid (UC3M) are developing a new transmission mechanism with no touching parts, based on magnetic forces which prevent friction and wear and make lubrication unnecessary. It can be applied in space travel and exploration but has also been adapted for use in other areas, such as the railroad and aircraft industries. 3This research is being carried out under the auspices of Magdrive, a European research project coordinated by Professor José Luis Pérez Díaz, from the UC3M Instituto Pedro San Juan de Lastanosa, in which seven European entities participate. It consists of the development of a magnetic gear reducer, that is, a mechanism that transforms speed from an input axle to another in an output axle (as in a bicycle chain mechanism or the gearbox of an automobile). But in this case, unlike a conventional gear reducer, this transmission is produced without contact between the pieces thanks to the magnetism.
