  • Electricity is an invisible force that is used to transfer energy into heat, light, intelligence, or motion. Electricity is explained in terms of electrical charge, potential differ- ence (or voltage), electrical charge flow (or current), and resistance to current flow. Figure 1-1 graphically illus- trates electron flow through a conductor by comparing it with water flow through a pipe. The normal unit of current measurement is the ampere, whereas the normal unit of voltage measurement is the volt. The unit of opposition to current flow, or resistance, is the ohm...

  • This text started out many years ago as a lab-based text, one of the first such published by ISA—titled Basic Electrical Measurements and Calibration—in 1978, nearly 28 years ago. Many things in the electrical/ electronics industry have changed since this first edition was published. In the years following publication, digital instrumentation has become affordable, widespread, and has almost totally displaced analog devices in automation. While analog instruments have not completely disappeared, it is no longer the technology of choice for current automation installations....

  • 1. STEPPER MOTOR SYSTEMS OVERVIEW Motion Control, in electronic terms, means to accurately control the movement of an object based on either speed, distance, load, inertia or a combination of all these factors. There are numerous types of motion control systems, including; Stepper Motor, Linear Step Motor, DC Brush, Brushless, Servo, Brushless Servo and more. This document will concentrate on Step Motor technology. In Theory, a Stepper motor is a marvel in simplicity. It has no brushes, or contacts.

  • This textbook provides a thorough coverage of basic electrical and electronic theory at a level which is easily understood by the student who does not have a knowledge of advanced mathematics. Following the chapters explaining fundamental theory, the applications to electrical and electronic systems are described. Although a detailed study of advanced electronic systems is beyond the scope of the text, the last several chapters are devoted to descriptions of many of these systems as installed in modern aircraft and space vehicles.

  • Electric motors convert electrical energy into mechanical energy by utilizing the properties of electromagnetic energy conversion. The different types of motors operate in different ways and have different methods of calculating the performance, but all utilize some arrangement of magnetic fields. Understanding the concepts of electromagnetics and the systems of units that are employed is essential to understanding electric motor operation.The first part of this chapter covers the concepts and units and shows how forces are developed.

  • The electricity industry is changing rapidly. The first years of liberalisation mainly brought competition between utilities. The separation of supply (retail) from distribution, however, and the introduction ofcompetition for residential customers has taken the electric utilities out of their familiar territory into the stroppy waters of fighting for the consumer.

  • In writing this book the author has been primarily concerned with the presentation of the basic essentials of power-system operation and analysis to students in the final year of first degree courses at universities and colleges of technology. The emphasis is on the consideration of the system as a whole rather than on the engineering details of its constituents, and the treatment presented is aimed at practical conditions and situations rather than theoretical nicety.

  • Communication happens in the form of signals. Signals are transmission of energy (mechanical, electrical or light) through appropriate media. A signal that is constant and changed once conveys single information. The more changes in the signal, the more information that the signal can convey. For example, a push can mean one thing and removing it can mean another thing.

  • Getting started with basic electronics is easier than you might think. This Instructable will hopefully demystify the basics of electronics so that anyone with an interest in building circuits can hit the ground running. This is a quick overview into practical electronics and it is not my goal to delve deeply into the science of electrical engineering. If you are interested in learning more about the science of basic electronics, Wikipedia is a good place to start your search.

  • Most students of electricity begin their study with what is known as direct current (DC), which is electricity °owing in a constant direction, and/or possessing a voltage with constant polarity. DC is the kind of electricity made by a battery (with de¯nite positive and negative terminals), or the kind of charge generated by rubbing certain types of materials against each other. As useful and as easy to understand as DC is, it is not the only \kind" of electricity in use.

  • Which came fi rst, the chicken or the egg? I was faced with just such a quandary when I set down to create the original edition of this book. The way that I found people got the most out of the topics was to get some basic ideas and concepts down fi rst; however, those ideas were built on a presumption of a certain amount of knowledge. On the other hand, I realized that the knowledge that was to be presented would make more sense if you fi rst understood these concepts—thus my chicken-vs.-egg dilemma....
