This document discusses maglev trains, which use magnetic levitation to glide along tracks without touching the surface. It describes how maglev trains are propelled and guided using electromagnetic forces that lift and propel the train. Maglev trains offer advantages like higher speeds, less noise and pollution, and lower maintenance compared to traditional trains. However, their infrastructure is more expensive to build initially. The document outlines the basic principles, components, advantages and applications of maglev train technology.

3. MAGLEV - Magnetic Levitation
• Magnetic levitation is the use of magnetic
fields to levitate a metallic object.
• Manipulating magnetic fields and controlling
their forces can levitate an object.
• Using either Ferromagnetism or
Diamagnetism object can be levitated.
• A superconductor is perfectly diamagnetic
and electromagnets can exhibit varying levels
of ferromagnetism
Introduction

4. Why maglev trains needed ?
 Increasing pollution level from
automobiles
Depleting fuel resources
Limited range of buses and cars
Need for fast

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

6. BALANCE
UPLIFT

7. LEVITATIONS TECHNIQUES
1. Electromagnetic Suspension
2. Electrodynamic Suspension

8. •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.
PRINCIPLE OF LATERAL GUIDANCE

10.  Beam
 Levitation coil
 Guidance coil
 Propulsion coil

11. 1)The Maglev's speed can
vary from standstill to full
operating speed by simply
adjusting the frequency of the
alternating current.
2) To bring the train to a full
stop, the direction of the
travelling field is reversed.

12. • They do not have an engine.
• They do not use FOSSIL FUEL.
• Fast
• Quiet
• Easy maintenance
• Environmentally friendly
– No emissions
ADVANTAGES …

13. • Safety issues
– Or synchronization
could cause serious accidents
• Expensive to build
– $10-30 million per mile(1.6 km)
DISADVANTAGES …

14. They consume less energy.
Require no engine.
Move faster than normal trains because they are not
affected by ground friction.
 Incompatible with existing rail lines, unlike
traditional high-speed rail.
Initial cost is very high.
