Electromagnetic and Electromechanical Machines
The major emphasis in this third edition, as in the first, is placed on physical rather than mathematical concepts in the analysis of conventional electrical machinery such as electromagnets, reactors, transformers, rotating electromagnetic machines, and machine system performance.
The Obligation:
Engineering is more than a number-crunching business. It is a matter of life and death. In 1907, when engineering errors led to a Canadian bridge collapse that killed seventy-five men, the profession's moral obligations were stark and obvious. Engineers increasingly realized that technical expertise was not enough, and in 1925, a group of Canadian engineers formally and publicly promised to uphold the highest ethical standards. To remind themselves of their pledge, they fashioned iron rings to be worn on the outer finger. Unfortunately, for decades engineers in the United States had no similar institution. Then, on a summer day in 1970, 170 engineers, students, and teachers met on the campus of Cleveland State University for the first ceremony of what would become the Order of the Engineer. Today, the stainless steel rings worn by the Order's members are recognized throughout the world as the outward sign of an inward commitment to ethical engineering. This 50th Anniversary edition tells the story of the Order's origins and growth over half a century. Kip A. Wedel teaches American history at Bethel College in North Newton, Kansas.
Modeling and High Performance Control of Electric Machines
Modeling and High Performance Control of Electric Machines introduces you to both the modeling and control of electric machines. The direct current (DC) machine and the alternating current (AC) machines (induction, PM synchronous, and BLDC) are all covered in detail. The author emphasizes control techniques used for high-performance applications, specifically ones that require both rapid and precise control of position, speed, or torque. You'll discover how to derive mathematical models of the machines, and how the resulting models can be used to design control algorithms that achieve high performance. Graduate students studying power and control as well as practicing engineers in industry will find this a highly readable text on the operation, modeling, and control of electric machines. An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department. Instructor Support materials are also available.
