This fully revised edition of the book is systematically organized as per the logical flow of the topics included in electrical machines courses in universities across India. It is written as a text-cum-guide so that the underlying principles can be readily understood, and is useful to both the novice as well as advanced readers. Emphasis has been laid on physical understanding and pedagogical aspects of the subject. In addition to conventional machines, the book's extensive coverage also includes rigorous treatment of transformers (current, potential and welding transformers), special machines, AC/DC servomotors, linear induction motors, permanent magnet DC motors and application of thyristors in rotating machines.
Salient Features New and improved figures, diagrams and equations Explicit and rigorous treatment of transformers-;current, potential and welding transformers Auto transformers, Three Phase transformers, and Rotating machines are discussed in detail Detailed discussion of Polyphase Induction motors Covers electromechanical energy conversion Special machines, AC/DC servomotors, linear induction motors and permanent magnet DC motors (PMDC) Pedagogy includes solved numerical problems, practice problems, short answer questions and multiple choice questions with answers.
