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.
