Electrical Machines I

Electrical Machines I. Instructor: Dr. Debaprasad Kastha, Department of Electrical Engineering, IIT Kharagpur. Electrical machines are basically electromechanical energy conversion devices which convert electrical energy to mechanical energy and vice versa. There are different types of electrical machines that are used, although their basic operating principles are somewhat similar, they are very different from their point of view of construction and usage. This course will talk about two types of electrical machines, namely the transformer and the dc machine. (from nptel.ac.in)
