Electrical Machines

Electrical Machines is designed for the students of electrical and allied engineering programs to explain the principle, construction and working mechanism of various AC and DC Machines. The book begins with introductory chapters on electromechanical conversion theory, which forms the underlying principle of machines. It then discusses the principles, working, operating characteristics and control of various DC machines, followed by detailed chapters on Transformers and AC Machines. The last chapter of the book is devoted to the principles and working of certain special machines such as BLDC, Universal Motor and Hysteresis Motor. Key Features Presents detailed chapters on theory, analysis, performance and control aspects of various machines Pedagogy includes around 314 solved examples, 303 short and long answer questions, 159 multiple choice questions and 137 numerical problems Includes examples illustrated through MATLAB simulation as well Presents photographs of real machines and associated schematics Includes a chapter on Special MachinesOnline Resource CenterFor Faculty Chapter-wise PPTs Solutions ManualFor Students MCQ Test Generator Additional MATLAB codes Additional Reading MaterialTable of Contents1.
