Maglev

  1. 1. By, BejgamSoujanyaMAGLEVTrainsthat fly!!!!!!Trainsthat fly!!!!!!
  2. 2. ABSTRACT•By employing no wheels, maglev eliminates thefriction, and concomitant heat, associated withconventional wheel-on-rail train configurations.•“Driving without wheels, Flying without wings”deals with the present scenario of magneticlevitation (maglev) with Linear induction motor(LIM)
  3. 3. “DRIVING WITHOUTWHEELS,FLYING WITHOUTWINGS”
  4. 4. • 1750 – John Mitchell• 1900 – Robert and Emile Bachelet• 1970 – German and Japanese engineers startresearch and development towards theirversions of Maglev technology.INTRODUTION
  5. 5. How maglev worksHow maglev worksA maglev train floats about 10mm aboveA maglev train floats about 10mm abovethe guide way on a magnetic field.the guide way on a magnetic field.2 ways of levitating a train-2 ways of levitating a train-Electromagnetic suspension(EMS) andElectromagnetic suspension(EMS) andElectrodynamic suspension(EDS).Electrodynamic suspension(EDS).

  12. 12. • Less energy consumption because no rail-track friction• Requires no fossil fuel which can harm theenvironment.• Less noise pollution since the train never hitsthe track• MagLev guideways and trains take up lessspace than conventional trains
  13. 13. AdvantagesAdvantages• Because the train floats along there is noBecause the train floats along there is nocontact with the ground and therefore nocontact with the ground and therefore noneed for any moving parts.Hence there are noneed for any moving parts.Hence there are nocomponents that would wear out.components that would wear out.• The trains can attain speeds uptoThe trains can attain speeds upto330miles/hr which is not economically viable330miles/hr which is not economically viablefor commercial railwaysfor commercial railways

  15. 15. ApplicationsApplicationsNASA plans to use magnetic levitationfor launching of space vehicles into lowearth orbit.The mining industry will also benefitfrom Maglev.
  16. 16. CONCLUSION Research on this ‘dream train’has been going on for the last30 odd years in various partsof the world.
