Electrical machines form an integral part of a large electrical power system, with other components as well. The aim of this book is to give detailed theory of the experiments on the electrical machines. This laboratory manual on electrical machines is meant for electrical engineering students of B.E. and B. Tech. and polytechnics in India and abroad. This book gives the basic information to the students with the machine phenomenon, working principles and testing methods, etc. It also imparts a real physical understanding of various types of electrical machines.
The main attraction of this laboratory manual is its power point presentation for all experiments. With the help of this any college or institute can conduct these experiments using available machines with little modifications. By studying this PPT, an average student can also perform the experiments with great interest and enthusiasm.
The conclusion written at the end of each experiment will help the student as well as working engineers, to know the behaviour of various machines. This book will be a valuable asset to the practicing engineers, teachers and students.

    1. Experiments for second year of B.E. or B.Tech.
    2. Experiments for third year of B.E. or B.Tech.
    3. Experiments for second and third year of polytechnics.
