ABSTRACT

•By employing no wheels, maglev eliminates the friction, and concomitant heat, associated with conventional wheel-on-rail train configurations.

•“Driving without wheels, Flying without wings” deals with the present scenario of magnetic levitation (maglev) with Linear induction motor (LIM)

“DRIVING WITHOUT WHEELS,

FLYING WITHOUT WINGS”

• 1750 – John Mitchell

• 1900 – Robert and Emile Bachelet

• 1970 – German and Japanese engineers start research and development towards their versions of Maglev technology.

INTRODUTION

How maglev worksHow maglev works

A maglev train floats about 10mm A maglev train floats about 10mm above the guide way on a magnetic above the guide way on a magnetic field.field.

•Less energy consumption because no rail-track friction

•Requires no fossil fuel which can harm the environment.

•Less noise pollution since the train never hits the track

•MagLev guideways and trains take up less space than conventional trains

AdvantagesAdvantages• Because the train floats along there is no Because the train floats along there is no

contact with the ground and therefore no contact with the ground and therefore no need for any moving parts.Hence there need for any moving parts.Hence there are no components that would wear out.are no components that would wear out.

• The trains can attain speeds upto The trains can attain speeds upto 330miles/hr which is not economically 330miles/hr which is not economically viable for commercial railwaysviable for commercial railways

DisadvantageDisadvantage

The biggest problem is that The biggest problem is that it is much more costly than it is much more costly than conventional track railways and conventional track railways and governments around the world governments around the world aren't willing to invest so heavily aren't willing to invest so heavily in such a project.in such a project.

ApplicationsApplications

NASA plans to use magnetic levitation for launching of space vehicles into low earth orbit. The mining industry will also benefit from Maglev.

CONCLUSION

Research on this ‘dream train’ has been going on for the last 30 odd years in various parts of the world.
