3. INTRODUCTION:-
 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 because It
levitates due to the magnets
• Maglev is a short form of Magnetic
Levitation

4. HISTORY:
 1971: West Germany
(90 kmph)
 1972 : Japan (60
kmph)
 1975 : West Germany
(401.3 kmph)
 1979 : Japan (517
kmph)

5. The Technology:
 3 types of technologies are in use:
 EMS (Electro Magnetic Suspension)
 EDS (Electrodynamic Suspension)
 Inductrack System (Permanent Magnet Passive
Suspension)

6. EMS:
+++
 Low magnetic fields inside and
outside the vehicle
 Commercially available
 No secondary propulsion system
needed
---
 The system needs to be
monitored by outside system to
maintain the distance between
the Track and the train
 Vibraitions may occur due to
instability and outside
monitering

7. EDS (Electrodynamic Suspension)
 Principle: uses a repulsive force between two
magnetic fields to push the train away from the
rail

8. INDUCTRACK SYSTEM:
+++
 No power requiered to activate
the magnets
 Can levitate at low speed
(5km/h)
 Lower Costs
---
 Wheels needed at slow speed
Principle : Same system as the EDS, but the track is made of permanent
magnets. Magnetic field placed under the train

9. WORKING:-
 A maglev train floats about 10mm above the
guideway on a magnetic field
• It is propelled by the guideway itself
• 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

10. DIAGRAM:-

11. Block Diagrams:
•Figure 6.1 – High-Level Block Diagram
•Figure 6.2 – Next Level Block Diagram

12. 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

13. • 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

14. POWER SUPPLY
• Batteries on the train power the system, and
therefore it still functions without propulsion
• The batteries can levitate the train for 30
minutes without any additional energy
• Linear generators in the magnets on board of
the train use the motion of the train to recharge
the batteries
• Levitation system uses less power than the
trains air conditioning

15. MagLev vs. Conventional Trains
MagLev Trains Conventional Trains
No Friction = Less
Maintenance
Routine Maintenance
Needed
No Engine = No fuel
required
Engine requires fossil
fuels
Speeds in excess of
300 mph
Speeds up to 110 mph

16. EFFECT ON ENVIRONMENT:-
 It doesn’t need any kind of fuel
 It doesn’t send out any CO2

17. Future of conventional trains:-
 Future of conventional train is Maglev Train
 Hundreds of miles would be possible in few
hours

18. Advantages:-
• It is 250 times safer than conventional railroads
• 700 times safer than automobile travel
• Speeds up to 500 km/h
• A accident between two maglev trains is nearly
impossible
• Smooth motion & Less noisy

19. Contd…
• 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

20. CONTD…
•The train is earthquake proof because the
greater space (10 mm) 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

21. Disadvantages:-
 The big problem about this is that the pieces
for the maglev are really expensive
 The procedure to build it up is very expensive
as well

22. CONCLUSION:-
• 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
• Its construction cost is more but
maintainance cost is less
