Spin stabilized magnetic levitation



INTRODUCTION
The Levitron®1 ~Ref. 1! is a remarkable toy which levitates
in air a 22-g spinning permanent magnet in the form of
a small handspun top. The top is spun on a lifter plate on a
permanent magnet base and then raised to the levitation
height. The top floats about 3.2 cm above the base for over 2
min until its spin rate declines due to air resistance to about
1000 rpm. Unlike an earlier magnet toy which re ....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
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

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

Introduction To Maglev Technology And Application


1.1 Principle of Maglev System
Maglev is a system in which the vehicle runs levitated from the guideway (corresponding
to the rail tracks of conventional railways) by using electromagnetic forces between
superconducting magnets on board the vehicle and coils on the ground. The following is
a general explanation of the principle of Maglev.

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

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
