### Maglev Trains

1. 1. MAGLEV Driving without wheels, Flying without wings
2. 2. Maglev High-speed rail technology; train is suspended on a magnetic cushion above a magnetized track and so travels free of friction
3. 3. Index ➔Introduction ➔Basic Principle of Maglev Trains ➔Types of Maglev Trains ➔Flash File( about working of Maglev )
4. 4. INTRODUCTION Maglev=Magnetic + Levitation. Any thing which may levitate(raise or float) by means of a magnetic power is simply called as magnetic levitation. • Maglev is noiseless ,friction less , and require no maintenance. • The lack of friction allow maglev vehicle to travel at a speed over 300 miles/hr. • Electrified transport reduces pollution. The term ‘MAGLEV’ can be briefly explained by using an example of ‘MAGLEV TRAINS’.
5. 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. 6. Levitation • Levitation is a process by which an object is suspended by a physical force against gravity. • For example, a superconducting sample, which can be considered either as a perfect diamagnet or an ideally hard superconductor, easily levitates in an ambient external magnetic field.
7. 7. Propulsion • Propulsion is a means of creating force leading to movement. • Maglev uses magnetic levitation to suspend, guide and propel vehicles with magnets rather than using mechanical methods.
8. 8. Lateral Guidance • Maglevs need a guidance force to keep the vehicle on track. • It is obtained with the levitation electromagnets of particular shapes. • These are designed a/c to the rails and then clever placement of the electromagnets with respect to the rails is done.
9. 9. Types of Maglev Trains Based on the technique used for Leviation the are two types of Maglev trains 1. Electromagnetic Suspension -Attractive 2. Electrodynamic Suspension -repulsive New type of EDS
10. 10. Brief EXPLANATION Electromagnetic Suspension(EMS) Electromagnetic Suspension uses electromagnets to leviate the train Electrodynamic Suspension(EDS) Electrodynamic Suspension uses Superconductors for leviation, propulsion and lateral guidance
11. 11. Due to its successfull implementation. We will only study EMS
