Laboratory Manual for Electrical Machines (2nd) edition includes four new experiments in electrical machines so that it can cater to the complete syllabus of undergraduate laboratory courses of electrical machines. This book gives the basic information to the students with the machine phenomenon, working principles and testing methods, etc. It also imparts real physical understanding of various types of electrical machines. The main attraction of this laboratory manual is its power point presentation for all experiments.
