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.

This concise, complete primer on electric machines is specifically tailored for practicing engineers who require knowledge in this area and for mechanical and electrical engineering students. The authors focus on the similarities between the four main types of electric machines: the synchronous, the transformer, the dc machine, and the induction machine. This new edition moves logically from the presentation of background to problem analysis and problem solving sessions, on to hands-on experience in testing machines. Short examples are included at the end of each section as well as case studies as learning tools.
