Description
Principles of Electrical Machines provides a comprehensive discourse on the characteristics and working principles of various types of electrical machines. Starting with magnetic circuits which form an integral part of electrical machines, the book goes on to cover transformers and the general principles of energy conversion. The book then extensively discusses different types of electrical machines—dc machines, three-phase induction machines, and three-phase synchronous machines; single-phase motors, which are widely used in household and office appliances.
