Magnetic Levitation Train by Shaheen Galgali_Presentation

Magnetic levitation is a highly advanced technology which uses the principle of Electromagnetic suspension & Electrodynamics suspension technology. It has various uses, The common point in all applications is the lack of contact and no friction. This increases efficiency, reduces maintenance costs, and increases the useful life of the system. Magnetic levitation is a technique to suspend an object without any support other than that of a magnetic field. There are already many countries that are attracted to maglev system. Many system have been proposed in different parts of the worlds. Maglev can be conveniently considered as a solution for the future needs of the world. This contribution deals with magnetic levitation. An overview of types, principles and working of magnetic levitation is given with the example by train are presented.

Magnetic Levitation Train by Shaheen Galgali_Presentation

  2. 2.  Introduction Magnetic levitation  Principle of Maglev Train  Levitation Propulsion Lateral guidance  How Maglev train works  Track Construction of track  Advantage  Application  Future scope in India  References  Conclusion 2SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
  3. 3. • Why maglev train needed Increasing pollution level from automobiles Depleting fuel resources It is cheaper, faster, not congested, and has much longer service life need for fast • The lack of friction allow maglev vehicles to travel at a speed over 300miles/hour • Maglev trains are based on maglev principle And they are noiseless, frictionless, and require no maintenance 3SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
  4. 4. • Maglev is a short form of magnetic levitation • Maglev is the use of magnetic field to levitate a metallic object • Using either superconductive magnets or Permanent magnets object can be levitate • The term maglev can b briefly explained by using an example of “ Maglev Trains” 4SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
  5. 5. There are two technologies  Electromagnetic suspension(EMS) Uses attractive magnetic force of magnets  Electrodynamic suspension(EDS) Uses repulsive force between magnets 5SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
  6. 6. Maglev trains have to perform the following function to operate in high speed 1.Levitation 2. Propulsion 3. Lateral 6SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
  7. 7. • The eight figured levitation coil are installed on the sidewalls of the guidewall • When the on-board superconducting magnets pass at a high speed • An electric current is induced within the coils and creates a magnetic field. • This pushes the train upward so that it can levitate above the track. 7SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
  8. 8. • Propulsion coils on the guideway are used to exert force on the train by effectively a linear motor • 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 • propels the train which pulls and push move forward 8SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
  9. 9.  When one side of the train nears the side of the guideway, the super conducting magnet on the train induces a repulsive force from the levitation coils on the side closer to the train and an attractive force from the coils on the farther side. This keeps the train in the center. 2-May-16 SECAB I.E.T Vijayapur Dept. Of EEE 9
  10. 10. • The electromagnets on the underside of the train pull it up to the ferromagnetic rotor on the track and levitate the train by linear motor. • The magnets on the side keep the train from moving from side to side. • A computer changes the amount of current to keep the train 1 cm from the track. This means there is no friction between the train and the track! 10SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
  11. 11. • The track which the train moves is called guide way • This train uses superconducting electric magnets in the vehicle to levitate and propel the train. • These magnets are cooled by liquid helium or liquid nitrogen. This means that once electrified these magnets do not require additional energy. 11SECAB I.E.T Vijayapur Dept. Of EEE2-May-16

  15. 15.  It is safe and user friendly.  It is having low friction.  It tolerate weather and random conditions, leaves and sticks that fall on the track.  It is economical.  Less cost  No pollution  Avoid excessive vibration 15SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
  16. 16. APPLLICATION OF MAGLEV • Aerospace Engineering(space craft, Rocket) • Civil Engineering & Building Facilities( Fan etc ) • Biomedical Engineering(Heart pump) • Electrical Engineering(Magnet, etc) • Automotive Engineering(car etc) 2-May-16 SECAB I.E.T Vijayapur Dept. Of EEE 16
  17. 17. The Indian Ministry currently in the process of reviewing a proposal to start Maglev Train Maglev train from • Pune (Pimple Saudagar) to Mumbai (Panvel) • Mumbai to Delhi • Mumbai - Nagpur • Chennai - Bangalore - Mysore 2-May-16 SECAB I.E.T Vijayapur Dept. Of EEE 17
  18. 18. • The maglev Train: Research on this “dream train” has been going on for the last 30 odd years in various parts the world • The chief advantage of this type of train are: Non-contact and Non-wearing propulsion, independent of friction, no mechanical component like wheel axle • Maintenance costs decrease • The Maglev offers a cheap, efficient alternative to the current rail sysytem. A country like INDIA could benefit very much if this were implemented here. Further possible application need to be explored 18SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
