Maglev, or magnetic levitation, is a system of transportation that suspends, guides and propels vehicles, predominantly trains, using magnetic levitation. Trends in increased mobility of large masses with changing lifestyle for more comfort are leading to congestion on roads with automobiles. Besides, increasing pollution levels from automobiles, depleting fuel resources, critical dependence on the fuel import.The highest recorded speed of a Maglev train is 581 kilometers per hour (361 mph), achieved in Japan.
All operational implementation of maglev technology have had minimal overlap with wheeled train technology and have not been compatible with conventional railroad tracks. Because they cannot share existing infrastructure, maglev must be designed as complete transportation systems. The term “maglev” refers not only to the vehicles, but to the railway system as well, specified designed for magnetic levitation propulsion. Development of magnetic levitated transport systems is under progress in developed countries.
i am btech student in scms college kerala i want to do aproject based ob the principle magnetic levitation
hi i need 2 knw abt magnetic trains . a tchnical seminars i need full details
Magnetic Levitation Train
The objective of this project is to create a laboratory scale magnetic levitating train model
using Inductrack technology developed by Dr. Richard Post from Lawrence Livermore
National Labs, Previous work by Paul Friend is discussed as well as the physics
associated with Inductrack. The levitation and propulsion systems built in lab is
described. The conclusion includes the results and suggestions for future work on the
A Linear Synchronous Motor (LSM) was chosen to propel the train. A basic top view of
an LSM is shown in Figure 2.2 below. It consists of copper wire powered by 3ø AC
Power wrapped around slots cut in laminated iron. The iron is laminated to help
eliminate eddy currents. Each color represents a different phase with a 120° phase
difference between each line.
The Inductrack Technology uses the basic concepts above to first propel and then levitate
a train. The train consists of at least two sets of Halbach arrays. One set is placed over
the track to levitate the train, while the other set is placed above the motor to provide
When the motor is powered, the train begins to move on wheels along the track. The
levitation Halbach array induces current in the track which induces a magnetic field
around the slits to oppose the magnetic field of the levitation Halbach array. This
produces the levitation. The faster the train moves, the higher the train levitates. Paul
Friend’s research helped him plot levitation height vs. the velocity of the train as shown
in Figure 4.1. In this example, the train reaches a peak height due to the lessened effect
of the magnets on the track. The height and velocity of the track are dependent on
parameters of the track and Halbach array.
