MAGLEVS Transportation is one factor that influence our way of life most and has got a direct impact on a country''s economy. It was found that the
trains with
wheels accelerate beyond a certain limit. It exerts heavy dynamic head on the track and at high speeds the wheels begin slipping against the track. This led the scientists to think and develop
MAGLEV trains.
Magnetic levitation trains popularly known as ''Maglevs'', is the latest development in the locomotive industry. Maglevs does not run on wheels. Therefore they do not have any mechanical limitations to acieve high speed. There are two types of Maglevs: 1) One is the electro-magnetic suspension system, which uses the magnetic attraction principle. 2) Other is the electro-dynamic suspension system, which uses the repulsion priniciple to levitate the
Train from the guide way. The magnetic train floats on a magnetic field and is propelled by a linear induction motor. It is similar to electric motor except tat its stator windings underneath. It is powered by four 440V batteries. Magnets on train are super conducting where as rails are ohmic. The
principle on which the maglev works is that " Like poles repel and unlike
poles attract each other". Maglev is an elegant technology with many advantages over conventional means of transit. Because the maglev vechicles never touch the guide way, they make little noise and incur low maintenance costs. Writers ............
