9780891169918: Electric Machines Steady-State Operation: Steady State Operation

With numerous chapter problems and worked-out examples, this book presents a general introduction to electric machines, including their rating and certain economic considerations. Using a tradition presentation, the author includes a discussion of magnetic circuits and transformers, conventional dc, induction and synchronous machines. He closes with coverage of dynamics of electromechanical systems and incremental-motion electromechanical systems.
