MAGNETIC LEVITATION VEHICLE Abstract: This paper “Driving without wheels, flying without wings” deals with the present scenario of magnetic levitation (maglev) with linear induction motor (LIM). The magnetically levitated train has no wheels, but floats-- or surfs-- on an electromagnetic wave, enabling rides at 330 miles per hour. There are two basic types of non-contact Maglev systems Electro Dynamic Suspension (EDS), and Electro Magnetic Suspension (EMS). EDS is commonly known as “Repulsive Levitation,” and EMS is commonly known as "Attractive Levitation." Each type of Maglev system requires propulsion as well as "levitation." The various projects above use different techniques for propulsion, but they are all variations of the Linear Induction Motor (LIM) or Linear Synchronous Motor (LSM). The cost of making the guide way is a high percentage of the total investment for a maglev system. When the terrain becomes difficult Magley is best. Many of the tunnels, embankments, and cuttings necessary for roads and railroads are avoided because Maglev guide ways can be easily adapted to the topography. Adaption of Maglev system is a bit costlier, but deploys electricity in electromagnets in an extraordinarily efficient manner. Maglev will set off a transportation and broader scientific explosion. The Maglev Train: Research on this ‘dream train’ has been going on for the last 30 odd years in various parts of the world. The chief advantages of this type of train are: 1. Non-contact and non-wearing propulsion, independent of friction, no mechanical components like wheel, axle. Maintenance costs decrease. Low noise emission and vibrations at all speeds (again due to non-contact nature). Low specific energy consumption. Faster turnaround times, which means fewer vehicles. All in all, low operating costs. Speeds
