MEDIUM-LOW SPEED MAGLEV
Maglev, or magnetic levitation, is a transport which suspends guides and propels dominantly trains using magnetic levitation from a very large number of magnets for lift and propulsion. This method of locomotion is faster, quieter and smoother. Unlike conventional systems which require a 30 km/h minimum speed, Maglev is able to operate at any speed.
HISTORY OF MAGLEV
High speed transportation patents were granted to various inventors throughout the world. Early United States patents for a linear motor propelled train were awarded to the inventor, Alfred Zehden (German). The inventor was awarded U.S. Patent 782,312 (June 21, 1902) and U.S Patent RE 12,700 (August 21, 1907), another early electromagnetic system was developed by F.S. Smith. A series of German patents for magnetic levitation trains propelled by linear motors were awarded to Hermann Kemper 1937 and 1941. An early modern type of maglev train was described in U.S. Patents 3,158,765,
Magnetic system of transportation, by G.R. Polgreen (August 25, 1959).The first use of ¡°Maglev¡± in a United States patents was in ¡°Magnetic levitation guidance¡± by Canadian Patents and Development Limited. The world¡¯s first commercial automated maglev system was a low speed maglev shuttle that ran from the airport terminal of Birmingham International Airport to the nearby Birmingham International railway station between 1984 to 1995.
Based on experimental work commissioned by the British government at the British Rail Research Division laboratory at Derby, the length of the track was 600 meters (1,969 ft), and train ¡°flew¡± at an altitude of 15 millimetres (0.6 in). It was in operation for nearly eleven years, but obsolescence problems with the electronic system made it unreliable in its later years and it has now been replaced with a cable-drawn system. One of the original cars is now on display at Rail world in Peterborough, while the RTV31 hover train vehicle is preserved on the Nene Valley Railway in Peterborough
