II. ABSTRACT
As the world continues to grow and as cities continues to become more crowded and congested, our normal modes of transportation will not be able to handle these overpopulated areas. The answer to this transportation problem lies in the world of electro magnetism and superconducting magnets. Electromagnets and superconducting magnets have allowed us to create a magnetic levitation train nicknamed “MAGLEV” that floats on the track instead of being directly on it. This has a lot of potential to creat ....etc

Ever since the discovery of the wheel, man has been in constant pursuit to achieve better and faster means of transportation. The FLYING TRAINS that is the MAGLEV (magnetic levitation) trains is the realization of such zestful endeavors. These ultra high-speed trains are acting as an indisposable resource to make the world smaller. Maglev is a generic term for a family of technologies in which a vehicle is suspended, guided and propelled by magnetic forces. Due to its need for an entirely new infrastructure, maglev technology has had a prolong ....etc

MAGNETIC LEVITATION SYSTEM
plant consists of an electromagnet, an optic position sensor, a
ferromagnetic sphere and a power interface.
Due to the spherical shape the measurement is nonlinear and needs
to be electronically or digitally linearised.

Velocity estimation
For fast nonlinear and unstable dynamical systems, such as magnetic
levitation, high quality of control is essential.
The ball velocity measurement is a dicult task.
Measurements of position and current is used for the velocity
estimatio ....etc

MAGLEV TRAINS



ABSTRACT:

The concept of magnetically levitated or maglev trains is of very much interesting.
The conventional trains with wheels and guide rails turn to be uneconomical beyond 200 km/hr because at this high speed, air resistance and hence the drag force increases. Therefore, they are very much expensive and require intensive maintenance. Maglev trains avoid these disadvantages and prove highly beneficial.

It is based on the three principles viz. electrod ....etc

Maglev- Magnetic Levitation Vehicle



Introduction

Levitation means to raise or float against the gravitational force. So, Magnetic Levitation is that a raise made using magnets or magnetic field. The train which runs using this principle is called as “Magnetic Levitation Trains” or “Maglev Trains”.
These trains will float over a track called the guide way using the basic principles of magnets, replacing the steel wheel and track trains.

Magnetic Levitation
Introduction
Magnetic Levitation is a way to suspend objects in air without any support, as if in defiance of gravity. An unsung phenomenon of the past which is now being put to use in a variety of interesting and useful applications. As a child we must have seen a ping pong ball being levitated on an air stream at the output pipe of a vacuum cleaner. Magnetic levitation, also known as maglev is used in a similar way to levitate objects in air without any support, using magnetic field. Levitation is the process by which an ....etc

Maglev Trains


1. INTRODUCTION
1.1 History
First generation Maglev systems have been developed in Japan and Germany.
Hermann Kemper began research on Maglev system in Germany and conducted successfully tests in the 1930’s (receiving a patent in 1934).
In the late 1960’s the German government began a study of traffic and modes which led to the development of very high speed maglev system by the German ministry of research and technology. The development included short stator, EDS and EMS technology and sy ....etc

The concept of this break through technology in transportation system was put forward by the American rocket scientist Robert Goddard in 1904. His hypothesis that by the sheer use of electromagnetic rails, the trains could be lifted off the tracks gained popularity with many nations of the world. Intense investigations and plans were charted out by Japan and Germany by the 70â„¢s on this notion on flying trains.

The movement of maglev train is based on the concepts of magnetism and magnetic fields, formed by the utilization of high-powe ....etc
