Maglev2
- 1. 8th SEM project submitted by- Swapnil,Tarun, Seraj, Sonu
- 2. WHAT DOES IT MEANS ?
- 3. DRIVING WITHOUT WHEELS - FLYING WITHOUT WINGS - IT DOESN’T ROLL - IT HOVERS .
- 4. MAGLEV TRAIN uses noncontact magnetic levitation, guidance and propulsion systems and have no wheels, axles and transmission.
- 5. ELECTRICITY AND ELECTRONICS - INSTEAD OF MECHANICS
- 6. WHY?!
- 7. Rapid growth of populations and the never ending demand to increase the speed of travel has always been a dilemma for city planners.
- 8. Current land transportation is slow Land speed is limited by friction Flying is expensive Air and land travel takes up a lot of fuel.
- 10. SPECIFIC ENERGY CONSUMPTION (WATT-HOURS / SEAT – KILOMETER)
- 11. OVERALL SYSTEM MAINTENANCE COSTS (CENT / SEAT –KM)
- 12. CO2 EMISSION (GRAMS PER SEAT – KM)
- 13. • It is the first fundamental innovation in railroad technology since the construction of the first railroad.
- 16. LEVITATION attractive forces created between the train and the track.
- 17. Basic Principle of Maglev Trains 1.Levitation 2.Propulsion 3.Guidance
- 18. EMS SYSTEM (ENERGY MANAGEMENT SYSTEM)
- 19. Types of Maglev Techniques 1. Electro magnetic Suspension - Attractive 2.Electro dynamic Suspension – Repulsive 3.Inductrack
- 22. GUIDANCE functions according to the principle of electromagnetic levitation. guidance magnets keep it laterally on track.
- 24. PROPULSION The synchronous long stator linear motor of the maglev system is used both for propulsion and braking.
- 28. ELECTRODYNAMIC SUSPENSION It uses magnets that has same polarity to create repulsive force between levitation magnet and guideway magnet. This repulsive force then will be high enough to overcome gravitational force and allows it to levitate.
- 29. ELECTROMAGNETIC SUSPENSIONS The electromagnetic suspension EMS uses attractive force system to levitate. The train’s levitation magnet will be attracted to the conductors on the underside of the guideway. The attractive force between them will overcome the gravitational force. This will in turn levitates the train
- 30. INDUCTRAC The inductrack is a newer type of EDS that uses permanent room-temperature magnets to produce the magnetic fields instead of powered electromagnets or cooled superconducting magnets. Permanent magnets had not been used before because scientists thought that they would not create enough levitating force.
- 31. (...) Permanent magnets had not been used before because scientists thought that they would not create enough levitating force. The Inductrack design bypasses this problem by arranging the magnets in a Halbach array. The magnets are configured so that the intensity of the magnetic field concentrates above the array instead of below it. They are made from a newer material comprising a neodymium-iron-boron alloy, which generates a higher magnetic field.
