3. INTRODUCTION
MAGLEV trains use the principle of magnetic
levitation to carry and propel vehicles with magnets,
increasing efficiency due to reduced friction. The
current project aims to conduct a case study and
implement a working model of MAGLEV train using
permanent magnets for levitation and a propeller for
movement.
4. Maglev Technology
For electromagnetic suspension (EMS) electronically
controlled electromagnets. In the train attract it to a
magnetically conduction track.
Electrodynamics suspension (EDS) uses
superconducting electromagnets or strongly
permanent magnets which pushes and pulls the train
towards the designed levitation. Position on the guide
way.
5. Innovative Technology
First fundamental innovation in the field of railroad
technology since the invention of the railway
A high speed maglev train uses non-contact magnetic
levitation, guidance and propulsion systems and has no
wheels, axles and transmission
Compared with traditional railways, maglev systems have
features that could constitute an attractive transportation
alternative:
1. High Speed
2. High Safety
3. Less Pollution
4. Low Energy Consumption
6. Basic Laws for Magnetic Levitation
FARADAY’S LAW
Induced electromotive force generates a current,
which flows in such direction as to induce a counter
magnetic field that opposes the magnetic field
generating the current
LENZ’S LAW
Induced electromotive force generates a current,
which flows in such direction as to induce a counter
magnetic field that opposes the magnetic field
generating the current
7. Track Technology
The inductrack is a newer type of EDS that uses
permanent room-temperature magnets to produce the
magnetic fields instead of powered electromagnets.
Permanent magnets had not been used before because
scientists thought that they would not create enough
levitating force.
8. Construction Details
The components that are used in this project:
•Permanent magnet motor
•Metal permanent magnets
•Fan
•Switch
•9 volt battery
•Wires
•Fibre base
9. Stability
Stability is a main factor for every system, so we have to
consider the stability for this MAGLEV train also.
Earnshaw’s theorem shows that any combination of
static magnets cannot be in a stable equilibrium.
Therefore a dynamic magnetic field is require to
achieve stability.
10. Project Goal
To make the Maglev train system as cost and energy
effective as possible.
Our project observes only the components that will
affect the effectiveness of the entire system, which also
accounts for the economic costs
The station stops will affect the speed of the train,
because depending on the distances, the train will not
be able to reach maximum speeds. Increasing the
number of stops increases the overall travel time, but
increases the amount of money generated by the
Maglev system.
11. Future scope
Some countries like China have embraced it and others
like Germany have balked at the expense
This system is not ready for use now, but it should be
ready within few years. The train is earthquake proof
because the greater space (10cm) between the tracks
and the train leaves more rooms for track deformation
12. Conclusion
Superconducting material was not used because of
climate conditions. Instead an array of permanent
magnets was used during the implementation which
can also be replaced by electromagnets for greater
efficiency
Guideways are very expensive.
Proper environment is needed. Our country’s climate
condition is difficult to execute this type of technology.
Maintenance cost is high.
Maglev track is highly electrified, therefore a lot of
safety is needed
