ethesis.nitrkl.ac.inmechanical energy via different kinds of electric motors- DC Motors, Synchronous Motors and Induction Motors. Induction Motors are often termed the “Workhorse of the Industry”. This is because it is one of the most widely used motors in the world. It is used in transportation and industries, and also in household appliances, and laboratories.
