Download or read book Theory of Electrical Machines written by Claudio Bruzzese and published by Società Editrice Esculapio. This book was released on 2022-01-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprehends basic and advanced theoretical tools for the analysis of structure and operation of power electrical machines. The principal machine typologies are discussed: single and three phase transformer, induction machine, and synchronous machine. The first chapter resumes important notions of electromagnetism, oriented to the study of electrical machines: starting from the properties of Maxwell’s equations in matter (in particular in magnetic materials), electric and magnetic integral laws and their application to practical electric and magnetic circuits are explained. In the subsequent chapters the electrical machines are analyzed in first from a physical point of view, and then suitable models, equations, and equivalent circuits are derived from the fundamental principles. The AC operation is deepened, by using both time-domain and frequency domain equations and equivalent circuits, since this is the main operating modality. The text is mainly targeted to students enrolled in a Master degree in Electrical Engineering, and is designed to be used for a one- or two-semester course in electrical machines. The prerequisites for effective use of the text are the courses of mathematical analysis, physics, and circuit theory.

Download or read book The General Theory of Alternating Current Machines written by Bernard Adkins and published by Springer. This book was released on 2013-11-11 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book on The General Theory of Electrical Machines, by B. Adkins, which was published in 1957, has been well received, as a manual containing the theories on which practical methods of calculating machine performance can be based, and as a text-book for advanced students. Since 1957, many important developments have taken place in the practical application of electrical machine theory. The most important single factor in the development has been the increasing availability of the digital computer, which was only beginning to be used in the solution of machine and power system problems in 1957. Since most of the recent development, particularly that with which the authors have been concerned, has related to a. c. machines, the present book, which is in other respects an up-to-date version of the earlier book, deals primarily with a. c. machines. The second chapter on the primitive machine does deal to some extent with the d. c. machine, because the cross-field d. c. generator servesas an introduction to the two-axis theory and can be used to provide a simple explanation of some of the mathematical methods. The equations also apply directly to a. c. commutator machines. The use of the word 'general' in the title has been criticized. It was never intended to imply that the treatment was comprehen sive in the sense that every possible type of machine and problem was dealt with.

Available in PDF, EPUB and Kindle. Book excerpt: Electrical Machines primarily covers the basic functionality and the role of electrical machines in their typical applications. The effort of applying coordinate transforms is justified by obtaining a more intuitive, concise and easy-to-use model. In this textbook, mathematics is reduced to a necessary minimum, and priority is given to bringing up the system view and explaining the use and external characteristics of machines on their electrical and mechanical ports. Covering the most relevant concepts relating to machine size, torque and power, the author explains the losses and secondary effects, outlining cases and conditions in which some secondary phenomena are neglected. While the goal of developing and using machine mathematical models, equivalent circuits and mechanical characteristics persists through the book, the focus is kept on physical insight of electromechanical conversion process. Details such as the slot shape and the disposition of permanent magnets and their effects on the machine parameters and performance are also covered.
