  • MAGNETIC LEVITATION (MagLev) By Nazia Banoo Siddiqui (EEE,6th sem)
  • What is MagLev?MagLev Technology; -levitates objects in air - electromagnetic propulsion - caused by electro magnets
  • Technology in MagLev1)ELECTROMAGNETIC SUSPENSION; - uses attractive magnetic force of a magnet.2)ELECTRODYNAMIC SUSPENSION; -uses repulsive force between 2 magnetic fields
  • Basic Concepts Of MagLev are- - Halbach Array -Levitation Track -Propulsion system
  • Halbach Array•grade 38, Neodymium-IronBoron (NdFeB).•Posses “ one-sided flux” structure
  • MagLev “Guideways” or Tracks Track repels magnets on undercarriage of train, sending the train forward. Train levitates between 1 and 10 cm above guideway.
  • Levitation Track Using laminated copper sheets
  • PropulsionA Linear Synchronous Motor (LSM) propels the train. copper wire powered by 3ø AC
  • Inductrack Technologybasic concepts - propel & levitate
  • Velocity of train vs. height
  •  Advantages of Inductrack system are; low weight low power requirements non adhesive drive system Disadvantages are; early development status lack of control over levitation
  • Travel Speeds At 300 kmph cheaper than flying!!!! Maglev
  • MagLev vs. Conventional Trains MagLev Trains Conventional TrainsNo Friction = Less Routine MaintenanceMaintenance NeededNo Engine = No fuel Engine requires fossilrequired fuelsSpeeds in excess of Speeds up to 110 mph300 mph
  • Better for the Environment Less energy consumption because no rail- track friction Requires no fossil fuel MagLev guideways & trains take up less space than conventional trains Less noise pollution
  • Obstacles Expensive guideway. Existence of conventional high speed train. Health concerns due to electromagnetic fields. Lack of investment
  • MagLev Applications Disneyland’s California Adventure Coaster& roller coaster uses MagLev technology to propel car from 0-55 mph in less than 5 seconds! Disneyland® - California Screamin
  • Other applications are- U.S. military is looking into using MagLev Possible uses could include:  Rocket launching  Aircraft carrier launching pad  Space craft launching
  • Present Scenario Commercially viable It will run for commercial service At present countries like germany, japan & china have shown their interest. Since 1990 maglev has gained status of nationally funded project.
  • Conclusion Department of Energy, found that “maglev technology” is a technically feasible transportation system. The Inductrack technology will require a long and expensive development period
