Principle of WorkingPrinciple of Working(EMS)(EMS)

Electro-magnetic SuspensionElectro-magnetic Suspension

This means there is no friction between the train and the track!

How EMS works?How EMS works? We know that opposite poles repel each other We know that opposite poles repel each other

and this fact is used to support the working of and this fact is used to support the working of a maglev train.a maglev train.

Electromagnets of opposite polarity are helpful Electromagnets of opposite polarity are helpful in lifting the train in air for around ten in lifting the train in air for around ten centimeters.centimeters.

Therefore there is no physical contact of the Therefore there is no physical contact of the train with the earth.train with the earth.

This is the basic concept.This is the basic concept.

Levitation System’s Power SupplyLevitation System’s Power Supply

Batteries on the train power the system, and therefore Batteries on the train power the system, and therefore it still functions without propulsion. it still functions without propulsion.

The batteries can levitate the train for 30 minutes The batteries can levitate the train for 30 minutes without any additional energy.without any additional energy.

Linear generators in the magnets on board the train Linear generators in the magnets on board the train use the motion of the train to recharge the batteries.use the motion of the train to recharge the batteries.

Levitation system uses less power than the trains air Levitation system uses less power than the trains air conditioning.conditioning.

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.

•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.

.

The + PointsSafety

•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.

Maintenance

• There is very little maintenance because there is no contact between the parts.

Comfort

•The ride is smooth while not accelerating..

Economic Efficency

•The initial investment is similar to other high speed rail roads. (Maglift is $20-$40 million per mile and I-279 in Pittsburg cost $37 million per mile 17 years ago.)

•Operating expenses are half of that of other railroads.

•A train is composed of sections that each contain 100 seats, and a train can have between 2 and 10 sections.

•The linear generators produce electricity for the cabin of the train.

Speed

•The train can travel at about 300 mph.

•For trips of distances up to 500 miles its total travel time is equal to a planes.

•It can accelerate to 200 mph in 3 miles, so if implemented in India, the time taken to travel to kanyakumari from Kashmir would reduce to 6 hours which is currently about 70 hours.

Environment

•It uses no fossil fuel for propulsion and hence it is low at pollution.

•There is no smoke, no gases, no wastes and therefore the environment remains clean.

•The risk of global warming is too low to be considered as this means of transportation is totally gas free.

•Noise Pollution

•The train makes little noise because it does not touch the track and it has no motor. Therefore, all noise comes from moving air. This sound is equivalent to the noise produced by city traffic.

Magnetic Field:

•The magnetic field created is low, therefore there are no adverse effects.
