This book on
"Electrical Machines" has been written for students preparing for
B.E./B.Tech, A.M.I.E. section B, U.P.S.C., and other
Competitive Examinations. It consists of two parts:
Part I ? deals with D.C. machines, and
Part II ? deals with A.C. machines and Polyphase circuits. Besides this,
"Additional Topics" and a
"Questions Bank" on
"Objective Type Questions" have been incorporated at the end of the book to make it a comprehensive unit in all respects.
Salient Features:- The presentation of the subject matter is very systematic and the language of text is lucid, direct and easy to understand.
- Each chapter of book is saturated with much needed text supported by neat and self-explanatory diagrams to make the subject self-speaking to a great extent.
- A large number of solved examples, properly graded, have been added in various chapters to enable the students to attempt different types of questions in the examination without any difficulty.
- At the end of each chapter Highlights, Objective Type Questions, Theoretical Questions and Unsolved Examples have been added to make the book a complete and comprehensive unit.
