Design of Voltage Regulator
A transformer is a device with two or more stationary electrical ckt that are conductively disjointed but magnetically coupled by a common time-varying magnetic Field. Transformer are basically passive device for transforming voltage and current one of the windings, generally termed as secondary winding, transformer energy through the principal of mutual induction and drivers power to the wad. The voltage level at primary and secondary windings are usually different and any increase or decreas ....etc

MOTIONLESS ELECTROMAGNETIC GENERATOR


ABSTRACT:
It introduce one of the revolutionary apparatus in the world of free
Energy / over unity devices, namely Motionless Electromagnetic Generator (MEG) .The major objective behind the invention of MEG is to design a magnetic generator in which the generation of electricity is accomplished without moving parts and moreover which eliminates a need for an external power source during itâ„¢s operation. In other words it is the objective to design a magnetic generator for which the coefficient o ....etc

INTRODUCTION
* Use of air gap magnetic flux probes-proven effective in detection of generator winding shorted turns
* Improve quality of predictive maintenance decision when or if to perform rework
* Can pinpoint the no: & location(pole & coil) of shorted turns without having to take generator offline
EFFECTS OF SHORTED TURNS IN ROTOR WINDINGS
* If percentage of total turns shorted out is small, the generator may be able to run at rated load for years without further proble ....etc

Abstract

An electromagnetic generator without moving
parts includes a permanent magnet and a magnetic core including first
and second magnetic paths. A first input coil and a first output coil
extend around portions of the first magnetic path, while a second input
coil and a second output coil extend around portions of the second
magnetic path. The input coils are alternatively pulsed to provide
induced current pulses in the output coils. Driving electrical current
through each of the input coils reduces a level of flux from the
per ....etc

FLUX ESTIMATORS FOR SPEED-SENSORLESS
INDUCTION MOTOR DRIVES



Abstract

This thesis deals with flux estimators for speed-sensorless induction motor drives. To enhance
the stability and the performance of state-of-the-art sensorless drives, new flux estimator
designs based on the standard motor model are proposed. Theoretical and experimental
research methods are both used. The dynamics and stability of flux estimators
are analyzed using linearized models, and the effects of parameter errors are investig ....etc

Abstract
A significant percentage of the flux used in submerged are welding gets converted into very fine particles particles
termed as flux dust due to transportation and handling. If these very fine particles are not removed fromt he flux before
welding, it may results ....etc

COUPLED FIELD ANALYSIS ON
WELD STRUCTURE
ABSTRACT

In the present scenario, products should be ensured for good quality. In order to achieve the required quality and reduced product development time, concept of Concurrent Engineering can be applied. Finite Element Analysis is one of the tools in concurrent engineering.
In this paper, the quality of a butt welded joint is analyzed using ANSYS 7.1- Finite Element Analysis Software. It is modeled as a three dimensional transient heat conduction problem. The process ....etc

Abstract:
The field oriented control emerged as an important approach for the control of AC machines, and continues to be explored and developed in the literature. The estimation of the rotor flux from the measurable variables was the only method used to implement the vector control of the induction machine. To replace the estimator based on the mathematical model of the system, which can lead to unintended errors due to uncertainties on the model and on the measures we use an appropriate observer.
