Description

Electrical Machines. Instructor: Prof. G. Bhuvaneshwari, Department of Electrical Engineering, IIT Delhi.

The course introduces electrical machines - namely transformers, DC and AC rotating machines, which are, arguably, the most important components of the energy and power conversion industry. Transformers, being static, are the easiest of electrical machines and hence they will be dealt with initially after introducing magnetic circuit fundamentals. DC and AC machines will be discussed after understanding the process of electromechanical energy conversion through a magnetic field. The efficiency, voltage regulation and characteristics of these machines will be discussed while they are functioning as generators. Further, their speed-torque characteristics, starting, braking, speed control and efficiency will be discussed while they function as motors. Every topic will include their applications in various power industries as well. (from nptel.ac.in)
