Stepping Motors, 4th Edition

Fri, 30 Oct 2020 15:43:11 GMT

Stepping motor technology is well established and used for motion control, most notably for computer peripherals but also wherever digital control is employed. This book provides an introductory text which will enable the reader to both appreciate the essential characteristics of stepping motor systems and understand how these characteristics are being exploited in the continuing development of new motors, drives and controllers. A basic theoretical approach relating to the more significant aspects of performance is presented, although it is assumed throughout that the reader has no previous experience of electrical machines and is primarily interested in the applications of stepping motors. Paul Acarnley's outstanding reference book is widely known and used, and this, the 4th edition, has been significantly updated to include many new applications that have emerged since the previous edition was published. Coverage includes: drive circuits, accurate load positioning, static torque characteristics, multi-step operation, torque/ speed characteristics, high-speed operation, open-loop control, closed-loop control and microprocessor-based stepping motor systems.

Telecommunications Quality of Service Management

Tue, 12 Jun 2018 01:36:26 GMT

In today's increasingly competitive communications environment, Quality of Service (QoS) is of paramount importance in the battle to win market share. However, the enhanced expectations of customers and the introduction of many new services and technologies makes comprehending and meeting customer requirements a real challenge. Building on the issues covered in Quality of Service in Telecommunications (1997), this book examines the technical, service and human issues that need to be addressed in order to provide a level of QoS that will meet those requirements. One key objective is to increase the reader's understanding of the importance of QoS and to show how the concepts presented can be applied to the reader's own circumstances. The book provides a comprehensive overview of definitions and standards, frameworks and models, network performance, internet, mobile and satellite services, the impact on customers, external drivers, economics, fraud and security and future trends. The authors, established experts in their fields, have wide-ranging experience in both UK and US telecommunications companies, reflecting the global nature of this industry and the universal concept of QoS.

Radio Man

Tue, 12 Jun 2018 00:34:11 GMT

Radio Man tells the story of C.O. Stanley, the unconventional Irishman who acquired Pye Radio at the beginning of the broadcasting age. Although he started with little experience and even less money, he was to make Pye a major player in the British electronics industry - only to crash it spectacularly forty years later. From the romance of early radio to the birth of the mobile, Stanley and Pye were players in some of the key moments of twentieth century Britain. His obsession with the infant medium of television allowed Pye to provide the equipment that put radar into planes in time for the Battle of Britain. His energy also drove Pye's pioneering work on the proximity fuse - work that would revolutionise antiaircraft warfare - and the company's manufacture of the war's most successful army radios.

In the 1950s Stanley led the offensive against the BBC's monopoly of television in a battle that split the British establishment. When his son, John, took Pye into mobile radio Stanley fought and defeated the bureaucrats who then controlled Britain's airwaves.

Stanley's loss of Pye in 1966 illustrated British industry's inability to withstand foreign competition. It also brought tragedy. Stanley himself escaped with honour more or less intact, but left his son to face public humiliation on his own.

This revealing and meticulously researched text is written within the broad context of the political, technological and business changes of the time, and shows how a very ambitious businessman was brought down by the qualities that made him so successful.

Developing Effective Engineering Leadership

Tue, 12 Jun 2018 00:25:26 GMT

Engineering companies and other organizations face many serious challenges in the 21st Century. One that is now becoming widely recognized is the loss of corporate knowledge through staff turnover, whether it is natural or forced through downsizing or delayering. A company's store of knowledge and expertise is an asset built up through the learning and experience of its employees.

In this book the authors show that such loss of experience and knowledge can substantially erode corporate culture and impact upon a company's ability to develop and reinvent itself in response to its market. The concentration is on process, culture, structure and leadership, to assist engineering organizations in managing their valuable knowledge resources and the people who possess them. It provides effective methodologies to devise solutions to the real challenges faced by engineering managers today.

Illustrated with scenarios and practical examples, which will be familiar to engineers worldwide, this book represents great value to all those in engineering management practice. In addition, as management increasingly appears within the syllabus of engineering courses, it will interest engineering students preparing for careers in industry, as well as their educators.

Power Systems Electromagnetic Transients Simulation

Mon, 11 Jun 2018 23:51:53 GMT

Accurate knowledge of electromagnetic power system transients is crucial to the operation of an economic, efficient and environmentally-friendly power system network, without compromising on the reliability and quality of the electrical power supply. Simulation has become a universal tool for the analysis of power system electromagnetic transients and yet is rarely covered in-depth in undergraduate programmes. It is likely to become core material in future courses.

The primary objective of this book is to describe the application of efficient computational techniques to the solution of electromagnetic transient problems in systems of any size and topology, involving linear and nonlinear components. The text provides an in-depth knowledge of the different techniques that can be employed to simulate the electromagnetic transients associated with the various components within a power system network, setting up mathematical models and comparing different models for accuracy, computational requirements, etc.

Written primarily for advanced electrical engineering students, the text includes basic examples to clarify difficult concepts. Considering the present lack of training in this area, many practising power engineers, in all aspects of the power industry, will find the book of immense value in their professional work.
