INTRODUCTION

• Why maglev train needed Increasing pollution level from automobilesDepleting fuel resources It is cheaper, faster, not congested, and has much longer

service lifeneed 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


MAGNETIC LEVITATION

• 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”


MAGLEV TECHNOLOGIES

There are two technologies

Electromagnetic suspension(EMS)Uses attractive magnetic

force of magnets

Electrodynamic suspension(EDS)Uses repulsive force between magnets


BASIC PRINCIPLE OF MAGLEV TRAINS

Maglev trains have to perform the following function to operate in high speed

1.Levitation 2. Propulsion 3. Lateral

LEVITATION

• 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.


PROPULSION

• 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


LATERAL GUIDANCE

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.


How Maglev train Works

• 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!


GUIDE WAY

• 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.


Track Construction

ADVANTAGES

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


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)


Future Scope in India

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


CONCLUSION• 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
