The document is a seminar presentation on maglev trains, covering topics such as their principle of operation, developers, types, and advantages over conventional trains. It emphasizes the technology of magnetic levitation that allows trains to move without contact with the ground, highlighting the differences between electromagnetic and electrodynamic suspension systems. Notable examples include the Shanghai Maglev Train and speed tests conducted by the Central Japan Railway Company.

4. MAGLEV is derived from term MAGNETIC LEVITATION
Basic principle of MAGLEV is called Magnetic Levitation
Maglev is Transport that uses magnetic levitation to move vehicles
without making contact with the ground
4Shanghai train(china)

5. DEVELOPER OF “MAGLEV TRAIN”
GERMANY and JAPAN Greatest developer of the MAGLEV TRAINS
Train construction is Same but prototypes different
JAPAN use Electromagnetic suspension (EMS)
GERMANY use Electrodynamic suspension(EDS)

6. This repulsion and attraction property
used in maglev train
Instead of using permanent magnet,
the principle of electromagnetism is used
to create strong and large temporary magnets

7. Basic Principle of MAGLEV Trains
Maglev trains have to perform the following function to operate in
high speeds
1. Levitation
2. Propulsion
3. Lateral guidance

North pole
Same pole repel-push the train forward
different pole attract-pull the train forward

9. TYPES OF MAGLEV TRAIN
Based on the techniques used for levitation
There are two types:-
1) Electromagnetic Suspension(EMS)
2) Electrodynamics Suspension(EDS)

ELECTROMAGNETIC SUSPENSION(EMS)
Electromagnetic suspension
uses electromagnets to
levitate the train
10

11. ELECTROMAGNETIC SUSPENSION(EMS)
In EMS use electromagnet to levitated the train
Electromagnet attached to the train
It has ferromagnetic stator to the train and levitation
 In EMS system Levitation by attraction magnetic force of magnet
Standard electromagnet use i.e. coil only conduct electricity when power supply is
present
Ems system can provide both propulsion and levitation using linear motor at the centre of
track
11

12. EMS uses “C” shaped that is connected to train and wrapped around the
train and connected to train
There is electromagnet located of lower part of “C” and inside of track
Guidance magnet keep magnet train centre and guide the train
Stator and support magnet levitate the
train 1 cm above the track
Levitation even when train is not moving

13. ELECTODYNAMIC SUSPENSION(EDS)
Electrodynamic suspension use super magnet to levitation, propulsion and
lateral guidance

14. ELECTODYNAMIC SUSPENSION(EDS)

In EDS system levitation by repulsion property
EDS system can only levitate the train using magnet not propel
it forward
Linear induction motor is used Propulsion system to move forward
Electromagnet on the underside of train and ferromagnetic
stator on track pull it up or levitate the train
Ac flow through the coil generate continuous varying
magnetic field that move forward along the track
(EDS SYSTEM )

15. Disadvantage of “EDS”
1. Maglev train must roll on rubber tires until reached a lift of speed about 62
miles/h(100km/h)
2.When it cross the 100km/h sped train levitation start
3.use super cooled , superconducting electromagnet, if in case of blackout
superconducting electromagnet can conduct electricity even after the power
supply OFF so it is costly
Disadvantage of “EMS”
1. System need to monitored by outside system to
maintain the distance between the track and train

16. “MAGLEV” train V/S “ CONVENTIONAL” Train
Maglev train Conventional train
No friction=less maintenance Routine maintenance needed
No engine=no fuel required Engine requires fossil fuels
Speed in excess of 300mph Speed up to 110mph
16

17. BETTER FOR ENVIRONVROMENT
Less energy consumption because no rail track
friction
Requires no fossil fuel
Maglev guidance and train take up less space than
convention train
Less noise pollution

18. Most famous commercial maglev train
1) Shanghai maglev train (shanghai-china)
Top speed-270 miles/hours
Average speed-160miles/hours
2) Central Japan railway company test speed in Japan
* 21 April 2015- 603km/hour
*2003 - 581 km/hour
