商品簡介
This text covers all aspects of electrical machines in a clear and concise manner at an introductory level. The emphasis is on machines as parts of systems rather than on the detail of the machines themselves, and on the applications of various types of machine.
The author begins by describing the mechanisms for torque and power production, particularly in three-phase power systems, and introduces the basic laws of electromagnetism and electromechanical energy conversion and the techniques of power electronics. This is followed by a detailed discussion of the operation, characteristics and control of major types of electrical machine (D.C., three-phase synchronous and induction machines). For each, a simple power system with a balanced and unbalanced load is considered. Less common and unconventional machines including stepper and micromotors are also outlined. The text concludes with a comparison with mechanical drives.
Extensive use of worked examples and of comments separated from the main discussions is made throughout the text.
The book is intended to provide an introduction to the operation and control of a range of electrical machines, and is targeted specifically towards students studying electrical, electronic or mechanical engineering at degree level.
