Trains that fly on air.

3. What is meant by Maglev?
 Maglev = Magnetic + Leviation
Any thing which may levitate(raise or
float) by means of a magnetic
power is simply called as magnetic
levitation.

4. Motion of the Maglev train
• Purely based on magnetism and magnetic fields
•Magnetic fields produced by powerful electromagnets
•Wheels eliminated from the train allowing it to
essentially move in the air frictionlessly

5. Basic Principle of Maglev
Trains
Maglev trains have to perform the following
functions to operate in high speeds
1.Levitation 2.Propulsion
3.Lateral Guidance

6. Magnetic leviation system
Based on the techniques used for
Levitation there are three types of Maglev
trains
1. Electro magnetic Suspension
2. Electro dynamic Suspension
3. Inductrack

7. Electromagnetic suspension
•The electromagnets on the
underside of the train pull it up to
the ferromagnetic stators on the
track and levitate the train.
•The magnets on the side keep the
train from moving from side to side.

8. Electrodynamic Suspension
Magnetic field produced by
superconducting magnets
located at the bottom of the
train
•The train is levitated by
the repulsive and
attractive force between
the magnetic fields of the
train and the guideway

9. inductrack
The major difference between the
Inductrack and the Electrodymanic
System is the use of permanent magnets
rather than superconducting magnets.

10. PROPULSION
•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 and propels the train forward.
•Braking is accomplished by sending an
alternating current in the reverse direction so
that it is slowed by attractive and repulsive forces.

11. GUIDANCE
 The Maglev train is a noncontact system that
requires a guiding force for the prevention of
lateral displacement

12.  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.

13. COMPARISION OF MAGLEV AND WHEEL
TRAIN
MAGLEV IRON WHEEL
 No mechanical contact
 No possibility of
derailment
 Mantainence very little
 Travels at very high speed
 Contact between wheels
and rails
 Derails from a minor
defect
 Needs mantainence quite
regularly
 Slower than maglev trains

14. Advantages
•The maglev tracks take up a lot less land,
because they are elevated. This also reduces
the amount of collisions and accidents.
•Maglev trains use far less energy than other
types of transportation.
•Maglev trains do not pollute
•Maglev trains are much faster
• Less maintenance

15. Disadvantages
 Cost and infrastructure
 Weight of the electromagnets is also an issue
 Feasible only in urban areas

16. RECORDS!!
On 21st
April, 2015 a maglev train operated by
central Japan Railway has set a world record of
603 kmph .

17. Conclusion
More energy efficient and environment friendly than present
day railway system
Maglev will have a positive impact on sustainability.
Maglev trains are the future of the transportation world.
