Year: 2008 Language: english Author: Juha Pyrh¨onen, Tapani JokinenHanna, Niemel¨a Genre: Technical book Publisher: John Wiley & Sons, Ltd Format: PDF Quality: eBook Pages count: 541 Description: 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. Finland has a strong tradition in electric motors and drives. Lappeenranta University of Technology and Helsinki University of Technology have found it necessary to maintain and expand the instruction given in electric machines. The objective of this book is to provide students in electrical engineering with an adequate basic knowledge of rotating electric machines, for an understanding of the operating principles of these machines as well as developing elementary skills in machine design. However, due to the limitations of this material, it is not possible to include all the information required in electric machine design in a single book, yet this material may serve as a manual for a machine designer in the early stages of his or her career. The bibliographies at the end of chapters are intended as sources of references and recommended background reading. The Finnish tradition of electrical machine design is emphasized in this textbook by the important co-authorship of Professor Tapani Jokinen, who has spent decades in developing the Finnish machine design profession. An important view of electrical machine design is provided by Professor Val´eria Hrabovcov´a from Slovak Republic, which also has a strong industrial tradition.
You could place the contents screen shots in the contents area rather than in the screenshots area and type the contents. Now You need to upload three screen shots from different parts of the book (I.e. beginning, mid and end ) in order to comply with the rules. Use the pencil on the top right hand corner to enter the edit status. There you can shift the syntax commands of the screenshots spoiler to the contents spoiler and to upload New images for the screenshots. Good luck.

Description: Electrical machines are almost entirely used in producing electricity, and there are very few

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.
