Electrical and Electronic Principles and Technology by
This much-loved textbook introduces electrical and electronic principles and technology to students who are new to the subject. Real-world situations and engineering examples put the theory into context. The inclusion of worked problems with solutions really help aid your understanding and further problems then allow you to test and confirm you have mastered each subject. In total the books contains 410 worked problems, 540 further problems, 340 multiple-choice questions, 455 short-answer questions, and 7 revision tests with answers online. This an ideal text for vocational courses enabling a sound understanding of the knowledge required by technicians in fields such as electrical engineering, electronics and telecommunications. It will also be an excellent refresher for foundation and undergraduate degree students. It is supported by a companion website that contains solutions to the 540 questions in the practice exercises, formulae to help students answer the questions, multiple choice questions linked to each of the 23 chapters and information about the famous mathematicians and scientists mentioned in the book. Lecturers also have access to full solutions and the marking scheme for the 7 revision tests, lesson plans and illustrations from the book.
Electric Machinery and Transformers by
Designed for junior- and senior-level courses in electromechanical energy conversion, Electric Machinery and Transformers, 3/e, continues the strong pedagogical tradition established by its successful previous editions. It begins with a review of the fundamentals of circuit theory andelectromagnetics and then introduces the concept of electromechanical energy conversion. The text not only provides a systematic development of a model for each electric machine based upon established principles and basic laws, but also introduces students to applications and advanced topics. Italso includes information on the construction of each electric machine. Electric Machinery and Transformers, 3/e, enhances student learning of the basic operating principles of electric machines by using numerous supporting examples, review questions, illustrations, exercises, and chapter summaries. It encourages intuitive reasoning for problem-solving over therote memorization of equations and procedures. This third edition covers the following main topics: principles of electromechanical energy conversion; transformers; direct-current generators and motors; synchronous generators and motors; polyphase induction motors and single-phase motors; the dynamics of electric machines; andspecial-purpose machines.
Electrical Machines by
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.
Non-Conventional Electrical Machines by
The developments of electrical machines are due to the convergence of material progress, improved calculation tools, and new feeding sources. Among the many recent machines, the authors have chosen, in this first book, to relate the progress in slow speed machines, high speed machines, and superconducting machines. The first part of the book is dedicated to materials and an overview of magnetism, mechanic, and heat transfer.
Rotating Electrical Machines by
In this book a general matrix-based approach to modeling electrical machines is promulgated. The model uses instantaneous quantities for key variables and enables the user to easily take into account associations between rotating machines and static converters (such as in variable speed drives). General equations of electromechanical energy conversion are established early in the treatment of the topic and then applied to synchronous, induction and DC machines. The primary characteristics of these machines are established for steady state behavior as well as for variable speed scenarios. Important new applications for this technology (such as wind turbines, electric propulsion systems for large ships, etc.) are addressed and the book is illustrated with a large number of informative and detailed photographs, provided by various companies at the leading edge of research and applications in the field.
