About Electric Machines: Theory, Operating
Product Description Retaining the user-friendly style of the First Edition, the Second Edition of this unique book provides detailed information on the application and safe operation of motors, generators, and transformers at the Technology Level, and includes examples in the use of NEMA and NEC Standards. With an emphasis on current industrial standards, this book presents AC machines and transformers before DC machines, motors before generators, gives more attention to machine characteristics, and makes extensive use of NEMA standards and tables. For Applications Engineers, Electrical Engineers, Maintenance Engineers, Marine Engineers, Mechanical Engineers, Nuclear Engineers, Operating Engineers, and Petroleum Engineers, who want an easy-to-understand, yet detailed explanation of the current industrial standards in the field of Electronics. From the Back Cover Here is what reviewers have to say about Electric Machines, Second Edition.The topic organization is certainly unique. I like the concept of developing AC machines first, particularly starting with motors before generators. The practical application concepts and problems are particularly interesting.We do need a machinery book with some NEMA standards and tables as found in Hubert's book. Because DC generators are internally AC generators, covering AC before DC is acceptable given a circuits course and knowledge of complex numbers as a prerequisite for this course.The author's years of experience with machines has resulted in a clean, concise delivery of the text material enhanced by accompanying schematics, pictures, and sample problems.I consider this text to be the best I have seen on the subject of electric machines. The writing style is very good, and the author has both practical and theoretical knowledge. I think this makes the text more believable to the students.A good blend between the simple approach to machines found in some texts and the highly technical approach found in others. Among all the new texts I have seen over the past few years, this is the best.I feel that the general order of topic coverage (transformers, AC machines, and DC machines) while different from the more usual order (DC, AC, transformers) is reasonable and in fact is the order that we have used in our courses for many years. Mr. Hubert's wealth of experience shows through and I am impressed with what I have read.For the general market, the most attractive feature is the stand-alone character of the major sections of the book. The material is well written and the coverage is thorough. Review questions have been well chosen, and homework problems cover the material well. Example problems are appropriate, applicable, and well conceived.When one is forced to teach such a course in one semester, one has to make choices on what to teach and on what to skip. In this respect, the author's decision to introduce AC machinery first and leave DC machinery as a standalone module provides some flexibility to the instructor on how to handle the material. Excerpt. © Reprinted by permission. All rights reserved. This second edition retains the easy-to-understand student-oriented approach that was the hallmark of the first edition. Additional steps were added to some derivations, and some example problems were expanded for even greater clarity and ease of understanding. New example problems and new homework problems were also added to further enhance student learning. Also added is a section on the high-efficiency NEMA design E AC motors. The text is designed to be used for a one- or two-semester course in electrical machinery. The minimum prerequisite for effective use of the text is a circuits course and a working knowledge of complex algebra and phasor diagrams. A review of current, voltage, and power relationships in the three-phase system, including applications of complex power, is provided in Appendix A for students who need extra help. The text is unique in tha
