  1. 1. 1 PRESENTEDPRESENTED BYBY:-:- MAGLEV TRAIN
  2. 2. Driving without wheelsDriving without wheels Flying without wingsFlying without wings 2
  3. 3.  Introduction.  History.  Principle.  How Maglev Works.  Benefits.  Current projects.  Banes And Boons.  Conclusion.  References. 3
  4. 4.  Maglev is a short for Magnetic Levitation.  Magnetic Levitation is the process of suspending an object in air with the help of magnetic fields.  The Maglev Train is one of the fastest transport media in the whole world.  The maximum speed reached for a Maglev train has been 581 kmh in Japan. 4
  5. 5.  In the 1960s in Britain Eric Laithwaite developed a functional maglev train. His maglev had 1.6 km of track and was in detail tested. His research was stopped in 1973 because lack of money and his progress was not enough.  1970 – German and Japanese engineers start research and development towards their versions of Maglev technology. Eric Laithwaite 5
  6. 6.  Maglev trains have to perform the following principles to operate in high speeds. 1. Levitation 2.Propulsion 3.Lateral Guidance 6
  7. 7. 7  A maglev train floats about 10mm above the guide way on a magnetic field.  2 ways of levitating a train-Electromagnetic suspension(EMS) and Electrodynamics suspension(EDS).
  8. 8.  Both ways have the same underlying concept-a magnet will repel another magnet. In both cases magnets in both the track and the undercarriage of the train repel each other to levitate the train. 8
  9. 9.  An alternating current is ran through electromagnet coils on the guide walls of the guide way. This creates a magnetic field that attracts and repels the superconducting magnets on the train and propels the train forward. Braking is accomplished by sending an alternating current in the reverse direction so that it is slowed by attractive and repulsive forces. 9
  10. 10.  Maglev uses 30% less energy than a high-speed train traveling at the same speed (1/3 more power for the same amount of energy).  The operating costs of a maglev system are approximately half that of conventional long-distance railroads.  Research has shown that the maglev is about 20 times safer than airplanes, 250 times safer than conventional railroads, and 700 times safer than automobile travel.  Maglev vehicle carries no fuel to increase fire hazard  The materials used to construct maglev vehicles are non-combustible, poor penetration transmitters of heat, and able to withstand fire. 10
  11. 11.  U.S.A -The united states Congress is planning to spend $1 billion for a test project that either connect Pittsburgh’s suburbs its airport or Baltimore to the Washington international airport .  GERMANY - A Transrapid connection linking the city centre of the Bavarian capital Munich to the airport (37 km) had been planned. It promised to reduce the connection time from about 40 minutes by the existing S-Bahn (German city railway system) to 10 minutes.  INDIA-The Indian Ministry is currently in the process of reviewing a proposal to start a Maglev train system in India.It has already been estimated that the cost to complete this process would be over $30 Billion. 11

  13. 13.  Banes :-  The biggest problem is that it is much more costly than conventional track railways and governments around the world aren't willing to invest so heavily in such a project.  Another problem is that the EM waves from the tracks may affect . mobiles and pacemakers of heart patients.  Boons:-  Maintenance  Friction  Speed  Less Noise 13
  14. 14.  . Maglev trains use magnets to levitate and propel the trains forward.  . Since there is no friction these trains can reach high speeds.  . It is a safe and efficient way to travel. 14
