MAGNETIC CIRCUIT

MAGNETIC CIRCUITS 4.1 INTRODUCTION TO ELECTROMAGNETISM •A conductor carrying a Current is always surrounded all along its length by a magnetic field. This important relationship between magnetism and current electricity which was discovered by Oersted in 1820 forms the basis of electromagnetism. Electromagnetism is the branch of engineering dealing with the magnetic effects of an electric current In this chapter, we shall study certain fundamentals 'of electromagnetism with special emphasis on magnetic circuits principles. summarized below, as it is assumed that students are already familiar with them. 4.2 MAGNETISM AND ITS EFFECTS •Before we begin the study of electromagnetism, some of the common terms used in magnetism are briefly • Important Properties of a Magnet: 0 () When freely suspended by a piece of silk fibre, it sets itself in a definite direction so that its North pole It attracts small pieces of iron. points towards the North direction and the South pole points towards...

INDUSTRIAL CONTROL BASIC

-
Introduction Motor starters are one of the major inventions for motor control applications. As the name suggests, a starter is an  electrical device which controls the electrical power for starting a motor. These electrical devices are also used for  the purpose of stopping, reversing and protecting electric motors. The following are the two major components of a  starter: THE BEST ELECTRICAL CONTROLS BUSINESS ON THE PLANET! Unmatched Service | Superior Product Quality | Advantage Pricing Page 1 of 9 1. Contactor: The main function of the contactor is to control the electric current to the motor. A contactor can  make or break power to the circuit. 2. Overload Relay: Overheating and drawing too much current can cause the motor to burn out and become  practically useless. Overload relays prevent this from happening and protect the motor from any potential  danger. A starter is an assembly of these two components, which allows it to turn on or off an electric...

ELECTRICAL ENGINEERING INTRODUCTION

-
Image
INTRODUCTION TO ELECTRICAL ENGINEERING aim of this blog is to introduce electrical engineering. The chapter is organized to provide the newcomer with a view of the different specialties making up electrical engineering and to place the intent and organization of the book into perspective. Perhaps the first question that surfaces in the mind of the student approaching the subject is, Why electrical engineering? Since this book is directed at a readership having a mix of engineering backgrounds (including electrical engineering), the question is well justified and deserves some discussion. The chapter begins by defining the various branches of electrical engi- neering, showing some of the interactions among them, and illustrating by means of a practical example how electrical engineering is intimately connected to many other engineering disciplines. In the second section, mechatronic systems engi- neering is introduced, with an explanation of how this book can lay the foundation for inte...

D.C Analysis

-
 DC analysis is one of the standard analyses that we can perform using PSpice. Other standard analyses include transient, AC, and Fourier. Under DC analysis, there are two kinds of simulation that PSpice can execute: DC nodal analysis and DC sweep. PSpice allows dc nodal analysis to be performed on sources with an attribute of the form DC value and provides the dc voltage at each node of the circuit and dc branch currents if required. To view dc node voltages and branch currents requires adding two kinds of additional parts, shown in Fig. D.11. The symbol VIEWPOINT is connected to each node at which the voltage is to be viewed, while the symbol IMPROVE is connected in the branch where the current is to be dis- played. This necessitates modifying the schematic. For example, let us consider placing voltage VIEWPOINTS and current IPROBES to the schematic in Fig. D.8(c). To add VIEWPOINTS, we take the follow- ing steps: 1. Click Draw/Get New Part (or type <Ctrl- G>). 2. Type VIEW...
