Pyrhönen Juha, Jokinen Tapani, Hrabovcovä Valëria. Design of Rotating Electrical Machines

John Wiley & Sons, Ltd, 2008. — 538 p.Electrical machines are almost entirely used in producing electricity, and there are very few electricity-producing processes where rotating machines are not used. In such processes, at least auxiliary motors are usually needed. In distributed energy systems, new machine types play a considerable role: for instance, the era of permanent magnet machines has now commenced.
About half of all electricity produced globally is used in electric motors, and the share of accurately controlled motor drives applications is increasing. Electrical drives provide probably the best control properties for a wide variety of processes. The torque of an electric motor may be controlled accurately, and the efficiencies of the power electronic and electromechanical conversion processes are high. What is most important is that a controlled electric motor drive may save considerable amounts of energy. In the future, electric drives will probably play an important role also in the traction of cars and working machines. Because of the large energy flows, electric drives have a significant impact on the environment. If drives are poorly designed or used inefficiently, we burden our environment in vain. Environmental threats give electrical engineers a good reason for designing new and efficient electric drives.In one complete volume, this essential reference presents an in-depth overview of the theoretical principles and techniques of electrical machine design. This book enables you to design rotating electrical machines with its detailed step-by-step approach to machine design and thorough treatment of all existing and emerging technologies in this field.Senior electrical engineering students and postgraduates, as well as machine designers, will find this book invaluable. In depth, it presents the following:
Machine type definitions; different synchronous, asynchronous, DC, and doubly salient reluctance machines.
An analysis of types of construction; external pole, internal pole, and radial flux machines.
The properties of rotating electrical machines, including the insulation and heat removal options.
Responding to the need for an up-to-date reference on electrical machine design, this book includes exercises with methods for tackling, and solutions to, real design problems. A supplementary website hosts two machine design examples created with Mathcad: rotor surface magnet permanent magnet machine and squirrel cage induction machine calculations. Classroom tested material and numerous graphs are features that further make this book an excellent manual and reference to the topic.About the Authors.Abbreviations and Symbols.
