2. INTRODUCTION
We are here trying to develop an idea to run a train based
on the technology of magnetic levitation. The magnets will
lift the train above the track by the magnetic forces and the
train will run some distance above the track. In that way we
will be able to totally remove the problem of friction.
3. Current Problems
Current land transportation is slow
Land is limited by friction
Flying is expensive
Air and land travel takes up a lot of fuel
4. Solution
Reduce friction for land travel
“Hover” just over the railroad tracks
Process is simpler than making a
plane fly
Staying on land is safer
5. The Maglev Train
• The Maglev Train is one of the fastest transport
media in the whole world.
• The maximum speed reached for a Maglev train has
been 581 kmh in Japan.
• The Maglev Train uses magnets to reach a really
high velocity
• It doesn’t touch the floor. It levitates because the
magnets.
• Maglev trains use magnets to levitate and propel the
trains forward.
• Since there is no friction these trains can reach high
speeds.
• It is a safe and efficient way to travel.
6. TWO TYPES DEVELOPED IN
WORLD
Transrapid
Transrapid is a German high-speed monorail train
Chuo Shinkansen
The Chuo Shinkansen is a planned Japanese maglev line
designed to ultimately connect Tokyo, Nagoya, and Osaka
7. Transrapid
Transrapid is a German high-speed monorail train using magnetic
levitation based on a 1934 patent. Planning for the Transrapid system
started in 1969 with a test facility for the system in Emsland, Germany
completed in 1987.
8. How Transrapid Works
Support System
•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.
•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!
9. Levitation System’s Power
Supply
• Batteries on the train power the system.
• The batteries can levitate the train for 30 minutes without
any additional energy.
• Linear generators in the magnets on board the train use
the motion of the train to recharge the batteries.
• Levitation system uses less power than the trains air
conditioning.
10. 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.
11. •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.
12. Application Information
Safety
•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.
13. Chuo Shinkansen
The Chuo Shinkansen is a planned Japanese maglev line
designed to ultimately connect Tokyo, Nagoya, and Osaka. Its initial
planned route is between Shinagawa Station in Tokyo and Nagoya
Station in Nagoya
14. How Chuo Shinkansen Works
Type of Magnet Uses
•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.
15. Principle:
In this, there are forces
which push the
superconducting magnet
upwards and ones which
pull them upwards
simultaneously, thereby
levitating the Maglev
vehicle.
16. •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.
Propulsion
17. A repulsive force and an
attractive force induced
between the magnets
are used to propel the
vehicle
Principle of propulsion:
18. An electric current
resulting in a repulsive
force acting on the
levitation coils of the side
near the car and attractive
force acting on the
levitation coils of the side
farther apart from the car.
Principle of Lateral guidance:
23. Application Information
• This system is not ready for use now, but it
should be ready in a few years.
• It’s top speed with people aboard is 350 mph.
• The super conducting magnets create a
strong magnetic field that could be a problem
for some passengers.
24. •The train is earthquake proof because the
greater space (10 cm) between the track and
the train leaves more room for track deformation
•Linear generators will produce all the electricity
needed in the train’s interior.
•Only the part of the track that is used will be
electrified so no energy is wasted.
26. Conclusion
There’s definitely a better way to travel
Currently test tracks are being built in America
Maglev transportation has a questionable future
