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 Electrical Machines written by Slobodan N. Vukosavic and published by Springer Science & Business Media. This book was released on 2012-10-26 with total page 666 pages. 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.

Download or read book Advancements in Electric Machines written by J. F. Gieras and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, electrical machines are classi?ed into d. c. commutator (brushed) machines, induction (asynchronous) machines and synchronous machines. These three types of electrical machines are still regarded in many academic curricula as fundamental types, despite that d. c. brushed machines (except small machines) have been gradually abandoned and PM brushless machines (PMBM) and switched reluctance machines (SRM) have been in mass p- duction and use for at least two decades. Recently, new topologies of high torque density motors, high speed motors, integrated motor drives and special motors have been developed. Progress in electric machines technology is stimulated by new materials, new areas of applications, impact of power electronics, need for energy saving and new technological challenges. The development of electric machines in the next few years will mostly be stimulated by computer hardware, residential and public applications and transportation systems (land, sea and air). At many Universities teaching and research strategy oriented towards el- trical machinery is not up to date and has not been changed in some co- tries almost since the end of the WWII. In spite of many excellent academic research achievements, the academia–industry collaboration and technology transfer are underestimated or, quite often, neglected. Underestimation of the role of industry, unfamiliarity with new trends and restraint from technology transfer results, with time, in lack of external ?nancial support and drastic - cline in the number of students interested in Power Electrical Engineering.
