Magnetic Levitation Train by Shaheen Galgali_Presentation
Magnetic levitation is a highly advanced technology which uses the principle of Electromagnetic suspension & Electrodynamics suspension technology. It has various uses, The common point in all applications is the lack of contact and no friction. This increases efficiency, reduces maintenance costs, and increases the useful life of the system. Magnetic levitation is a technique to suspend an object without any support other than that of a magnetic field. There are already many countries that are attracted to maglev system. Many system have been proposed in different parts of the worlds. Maglev can be conveniently considered as a solution for the future needs of the world. This contribution deals with magnetic levitation. An overview of types, principles and working of magnetic levitation is given with the example by train are presented.

Principle of Maglev Train

Construction of track
Future scope in India

• Why maglev train needed
Increasing pollution level from automobiles
Depleting fuel resources
It is cheaper, faster, not congested, and has much longer
need for fast
• The lack of friction allow maglev vehicles to travel at a speed
• Maglev trains are based on maglev principle And they are
noiseless, frictionless, and require no maintenance

• 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”

There are two technologies
Uses attractive magnetic force
Uses repulsive force between

Maglev trains have to perform the following function to
operate in high speed
1.Levitation 2. Propulsion 3. Lateral

• The eight figured levitation coil are installed on the sidewalls of the
• 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.
7SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
• 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
8SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
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.

• 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
This means there is no friction
between the train and the track!
10SECAB I.E.T Vijayapur Dept. Of EEE2-May-16
• 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.

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.
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)

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

• 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
A country like INDIA could benefit very much if this were
implemented here. Further possible application need to be
