Electric Machinery and Transformers has been written for students at the junior-senior level studying various types of electrical machines. Based upon many years of teaching experience, the textbook is developed in such a way that it provides maximum flexibility without any loss of continuity from one topic to another. We feel that this approach would enable an instructor to easily adapt the material to meet the requirements of a course in electrical machines. For institutions that are on a quarter system and offer only one course in electrical machines, we suggest that they concentrate more on the hndamenrals and budget the time for the advanced topics.
The textbook concentrates on the basic operation of each machine and tends to minimize the non-essentials. The material presented in each chapter progresses from established principles to advanced topics. In the second edition, we included a large number of review questions at the end of each chapter. Since the addition of review questions has been greatly appreciated by the students, we have kept it intact in the third edition as well. Based upon the comments received from students, other instructors, and reviewers, we have added substantial amount of new material either to remedy perceived deficiencies or to further clarify the concepts.
We have also changed some examples in the text to complement the theoretical development preceding each of these examples. In addition, we have also revised some of the exercises at the end of each section. As we stated in the second edition, these exercises are expected to nurture confidence and enhance the comprehension of the material presented in each section. We have also revised the problems at the end of each chapter and arranged them in such a way that they offer a wide range of challenges for the student.

These problems must be treated as an integral part of the learning process and the student should use intuitive reasoning to solve them. Some of the problems in the text require the solution of nonlinear equations and we suggest that the student should be encouraged to solve these problems using software packages such as MathCAD@. We have used MathCAD@ to solve almost all the examples in this textbook. We encourage the use of a software package because it reduces the drudgery of mundane calculations, enables the student to probe further into the intricacies of a machine, and helps the student to focus on “what if” types of queries.
Our basic philosophy in writing the third edition has not changed. We felt then and we strongly feel now that a superficial treatment of the subject based upon mere statements of facts leads only to the memorization of equations which are soon forgotten. In order to motivate the student, we must present the material in a systematic order. In other words, when teaching electric machines our objectives are to Explain the physical construction of a machine, Shed some light on its windings and their placement, Describe the fundamental laws that govern its operation, Justify the assumptions imperative to develop the relevant theory, and Emphasize its limitations.
Once the student acquires a clear understanding of a machine, we must then develop the necessary equations using as few fundamental laws as possible. Each equation should be put in proper perspective by associating it with the machine’s performance.
When the operating principles of a machine are explained properly and the corresponding equations are developed from basic laws, the student will learn to Appreciate the theoretical development, Reduce intimidation, and Grasp the powers of reasoning.
The end result of such a teaching process is that, in the future, the student will not hesitate to tackle even more difficult problems with confidence. We have tried our best to incorporate this philosophy in the development of the text.
