This Book "Generalized Theory of Electrical Machines" is designed as a textbook for the readers who have already studied the basics of common types of Electrical Machines. In this book, an attempt has been made to unify the treatment of Rotating Electrical Machines. The topics included in this book are Elements of Generalized Theory, Linear Transformations in Machines, DC Machines, Polyphase Synchronous Machines, Polyphase Induction Machines, Single Phase Motors, AC Commutator Motors and Transformers. An entirely new chapter is added in the present edition to deal with stepping motors, brushless dc motors and variable reluctance motors along with a wide variety of objective type of questions and answers.
Dr. RS. Bimbhra retired as Professor of Electrical and Electronics Engineering from Thapar Institute of Engineering and Technology (Deemed University), Patiala-147004. He has over 40 years of teaching and research experience in Electrical Engineering. He has published several papers in renowned journals at national and international conferences. Dr. Bimbhra is a fellow of I.E. (India), a member of I.E.E. (U.K.) and a life member of I.S.T.E.
