Focuses on the similarities of four types of electric machines: the synchronous machine, the transformer, the dc machine, and the induction machine. This edition includes a chapter on electric machines for special applications. It moves logically from analysis of the machines to the solution of practical machine problems. A thorough discussion of the methods used for testing the machines is also provided. The book explores the design, construction, and operating characteristics of the electric devices used in the transformation to and from electric energy. Opening with a discussion of how mankind has successfully harnessed the energy of wind, water, sun, nuclear fission, in order to make life comfortable, it explores some of the consequences of this activity on the environment. The book then proceeds to address the basic physics of energy and its conversion. Other features of the book include an examination of the basics of charge, capacitance, current, Ohm's Law as well as magnetic fields, inductance, inductive coupling, and ferromagnetism.This book should be of interest to electrical and electronic engineers; electrical technicians, supervisors and related personnel; mechanical engineers and machine/tool engineers and designers; and design engineers.

This book is about electric energy: its generation, its transmission from the point of generation to where it is required, and its transformation into required forms. To achieve this end, a number of devices are essential-such as generators, trans mission lines, transformers, and electric motors. We discuss the design, construc tion, and operating characteristics of the electric devices used in the transformation to and from electric energy. This text is designed to be used in a one-semester course in electric energy con version at the second-year level of the Bachelor of Engineering course. It is assumed that the student is familiar with the laws of thermodynamics and has taken a course in basic circuit analysis, including the application of phasors. We begin with a discussion of how humankind has successfully harnessed the energy of wind, water, the sun, biomass, animals, geothermal sources, fossils, and nuclear fission to make its life comfortable. Some of the consequences of this activity on the environment are examined. In Chapter 2, we review the basic physics of energy and its conversion. This may be, to some extent, a repetition of knowledge gained in high-school and first year university courses. However, we believe that such review is necessary to establish a suitable base from which to launch the subject of electric energy con version.
