PRESENTATION OUTLINE: INTRODUCTION WORKING PRINCIPLE PROPULSION SYSTEM POWER SUPPLY MAGLEV VS CONVENTIONAL TRAIN EFFECT ON ENVIRONMENT ADVANTAGES DISADVANTAGES APPLICATION INFORMATION CONCLUSION REFERENCE

INTRODUCTION:-:

INTRODUCTION:- 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 km\h in Japan. The Maglev Train uses magnets to reach a really high velocity. It doesn’t touch the floor because It levitates due to the magnets. Maglev is a short for Magnetic Levitation.

WORKING PRINCIPLE:-:

WORKING PRINCIPLE:- A maglev train floats about 10mm above the guidway on a magnetic field. It is propelled by the guidway itself rather than an onboard engine by changing magnetic fields Once the train is pulled into the next section the magnetism switches so that the train is pulled on again. The Electro-magnets run the length of the guideway.

PowerPoint Presentation:

PROPULSION SYSTEM The system consists of aluminum three-phase cable windings in the stator packs that are on the guideway . When a current is supplied to the windings, it creates a traveling alternating current that propels the train forward by pushing and pulling.

PowerPoint Presentation:

When the alternating current is reversed, the train brakes. Different speeds are achieved by varying the intensity of the current. Only the section of track where the train is traveling is electrified. .

POWER SUPPLY:

POWER SUPPLY Batteries on the train power the system, and therefore it still functions without propulsion. The batteries can levitate the train for 30 minutes without any additional energy. Linear generators in the magnets on board the train use the motion of the train to recharge the batteries. Levitation system uses less power than the trains air conditioning.

MagLev vs. Conventional Trains:

MagLev vs. Conventional Trains MagLev Trains Conventional Trains No Friction = Less Maintenance Routine Maintenance Needed No Engine = No fuel required Engine requires fossil fuels Speeds in excess of 300 mph Speeds up to 110 mph

Effect on Environment ::

Effect on Environment : It doesn’t need any kind of fuel. It doesn’t send out any CO2.

Advantages of a maglev Train:-:

Advantages of a maglev Train:- It is 250 times safer than conventional railroads 700 times safer than automobile travel Speeds up to 500 km/h. A accident between two maglev trains is nearly impossible because the linear induction motors prevent trains running in opposite directions.

Disadvantages:-:

Disadvantages:- The big problem about this is that the pieces for the maglev are really expensive The procedure to build it up is very expensive as well

PowerPoint Presentation:

APPLICATION INFO The trains are virtually impossible to derail because the train is wrapped around the track. Collisions between trains are unlikely because computers are controlling the trains movements.

`:

` The train is earthquake proof because the greater space (10 mm) between the track and the train leaves more room for track deformation. Linear generators will produce all the electricity needed in the train’s interior. Only the part of the track that is used will be electrified so no energy is wasted.

CONCLUSION:

CONCLUSION 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.
