ACTIVE MAGNETIC BEARINGS (AMB)
A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact, for example, they can levitate a rotating shaft and permit relative motion without friction or wear. In active magnetic bearings (AMB) a stable equilibrium is achieved by means of one or more control loops. The use of control loop for maintaining the gap between the shaft and bearing differentiate the active magnetic bearings (AMB) from pa ....etc

Abstract

Designing Magnetic Bearings

• Magnetic bearings are used to levitate flywheels so they can spin at high speeds without mechanical contact.
• The design of a bearing set to control a flywheel weighing 5100 lbs and spinning at 15,000 revolutions per minute was described in the paper, “Permanent Magnet Bias, Homopolar Magnetic Bearings for a 130 kW-hr Composite Flywheel,” by B. Murphy, H. Ouroua, M. Caprio, and J.Herbst.
• The paper was presented at the Ninth International Symposium on M ....etc

-: ABSTRACT:-
Bearings are valuable.... until they go bad, and then they are worthless. But the definition of Bad Condition of Bearing is not standardized yet. To quickly discover what bearings may be salvaged, we offers positive testing machine. Because “A Bearing Saved is a Bearing Earned”. We tried to compare the bearings on ideal and defective condition on Sound and Vibration factor. For Sound we used microphone and for Vibrations we implemented piezoelectric sensor. Instea ....etc

CHAPTER ONE
1.0 INTRODUCTION
Experience is the best teacher, it has been said. Although the relevance and importance of theoretical knowledge in any field of study can not be over- emphasized, the practical knowledge and experience is just as essential. It is to this end that the student industrial work experience scheme (SIWES) was instituted.
The Student Industrial Training Work Experience Scheme (SIWES) is now made compulsory exercise carried out by the entire 400level student across the country. This takes pla ....etc

Superconductor Ceramics and SiliconeComposite Dc Engine
Abstract
This paper gives a new approach to the use of compositematerials in dc engines for efficient power development.Composite materials are manufactured from two or morematerials with different properties. By means ofexamining the property of superconductor, it is found thatthey are perfect diamagnetic repellers and they arecapable of producing work. Such superconductingproperty can be achieved in the composite materialsconsisting of superconductor ceramics and metal or metal ....etc
