Maglev trains use magnetic levitation to float and propel trains along guideways without touching the surface. This is achieved through the interaction of magnets and electromagnetic coils that create both lift and thrust. Maglev trains can travel at speeds over 300 mph and have several advantages over conventional trains, including higher speeds, less energy use, and no friction between train and rails. While still under development, countries like Germany and Japan have operational maglev systems that could be improved upon to create faster, more efficient train travel in the future.

5. INTRODUCTION:
TRAINS THAT
FLY ON AIR

6. What is Maglev?

7. In order for the train float,
there must be two coils.
The top coil is installed in
the train and the bottom
coil is placed in the track .
Attraction is caused by
having the currents within
each of the circuits ,
traveling in the same
direction
LEVITATION BY ATTRACTION:

8. Similar poles of a magnet repel
each other . In order for the train
to float , there must be two coils.
The top coil is placed within the
train and the bottom coil is placed
on the track . The current in the
top circuit travels in the opposite
direction of the current in the
bottom , resulting in the repulsion
between two coils.
PROPULSION BY REPULSION:

9. PRINCIPLE OF MAGLEV:
● In this,there are forces
which push the
superconducting
magnet upwards and
ones which pull them
upwards
simultaneously, thereby
levitating the Maglev
vehicle.

11. The Maglev Train History
In the 1960s in Britain Eric Laithwaite
developed a functional maglev train. His
maglev had 1.6 km of track and was in
detail tested. His research was stopped in
1973 because lack of money and his
progress was not enough. In the 1970s,
Germany and Japan also began research
and after some failures both nations
developed mature technologies in the
1990’s……………………………………..

12. How does it work
●A maglev train floats about 10mm above the
guidway on a magnetic field.
It is propelled by the guidway itself rather than an
onboard engine by changing magnetic fields
Once the train is pulled into the next section the
magnetism switches so that the train is pulled on
again.
The Electro-magnets run the length of the
guideway.

13. The Maglev Train and Culture
●The Maglev Train has helped the people in some
countries to think better about the travel by train.
●I think it wouldn’t have worked in USA because it is a
bigger country that is developing and that is focusing
now in other industries. They also have plains that
connect every main city. It is easy to travel in
America.

16. LINEAR INDUCTION MOTOR IN MAGLEV:

20. The magnets on the train produce eddy
currents in the levitation coils when traveling
over them
The method of levitation requires a certain
velocity before levitation will occur

22. THE WORKING OF GUIDEWAY:

23. $200 = 32 NdFeB Permanent Magnets
$100 = Aluminum for Train
$120 = Model Track and Wheels
$43 = Wood for Guide Rails
FREE= Wire Wrapping for Guide Rails
$463 = Total Cost

25. Problem
●Current land transportation is slow
●Land is limited by friction
●Flying is expensive
●Air and land travel takes up a lot of fuel

26. 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

27. Implementation
●Strong magnets on moving car
●Magnetic forces hold car in position
●Vertically
●Inclining or declining track
●Weight distribution changing
●Horizontally
●Wind forces
●Turning

28. Superconducting Magnets
●Superconducting magnets on
train induce current on
conducting sheet
●Induced currents generate
magnetic repulsive force
●In conducting sheet guideway
there are power losses in sheet
●Slightly corrected by making
small conducting loops
●Still significant losses…

29. A Better Design
●James Powell, and Gordon
Danby invented the “Null-
Flux” system
●When the vehicle is at the
symmetry point of the loop,
the net magnetic flux
through the loop circuit is
zero

30. Forward
Propulsion
●No connection with track
●Linear Synchronous Motor used
●AC current in windings in the guideway
●Speed in controlled by frequency of the AC power
●High efficiency because only the section of track that the
train is on needs current

31. The MagLifter

32. ●The train can travel at about 300 mph. (acc.
can go only up to 200 mph).
●For trips of distances up to 500 miles its total
travel time is equal to a plane.
●It can accelerate to 200 mph in 3 miles, so it
is ideal for short jumps.
SPEED:

33. Advantages of Magnetic Levitated Transportion
system:
● Despite the speeds up to 500 km/hour, passengers
can move about freely in the vehicles at all times.
● Maglev vehicle carries no fuel to increase fire hazard
● The materials used to construct maglev vehicles are
non-combustible, poor transmitters of heat, and able
to withstand fire penetration.
● In the unlikely event that a fire and power loss
occurred simultaneously, the vehicle is automatically
slowed down so that it stops at a predefined
emergency power station.

34. ● A collision between two maglev trains is nearly
impossible because the linear induction motors
prevent trains running in opposite directions or
different speeds within the same power sectionically
reduce travel time.
● Maglev uses 30% less energy than a high-speed
train travelling at the same speed (1/3 more power
for the same amount of energy).
● The operating costs of a maglev system are
approximately half that of conventional long-distance
railroads.

35. CURRENT PROJECTS:
● Germany and Japan have been the
pioneering countries in Maglev research.
Currently operational systems include Tran
rapid (Germany) and High Speed Surface
Transport (Japan). There are several other
projects under scrutiny such as the Swiss
Metro, Seraphim and Induct rack. All have
to do with personal rapid transit.

46. ● Magnetic levitation is a phenomenon that
is likely to have considerable potential in
the future. Particularly through the use of
superconductive levitation.
● A new idea for magnetic levitation is in the
use of storage of energy. Very basically it
uses a rotating ring (flywheel) that stores
(kinetic) moving energy which can be
'extracted'
