Designed to serve as a textbook for a single semester undergraduate course on electromechanical energy conversion devices or electric machines, ELECTRIC MACHINES strikes a balance between theoretical coverage, easy explanations, and practical applications, presenting real world applications of concepts without compromising on the rigor or the continuity of the text. The book provides excellent readability, in a conversational style, combined with invaluable industry insight. The accompanying website provides problems solved in MATLAB, SPICE simulations, manufacturing data, as well as additional problems for students and instructors.

Features and Benefits

  • Inclusion of Control Schematics.
  • Clear and precise descriptions.
  • Many application based examples.
  • Great balance between high quality theoretical coverage, easy explanations, and practical application examples.

Efficacy and Outcomes


"As an instructor of Engineering Technology students, I was especially pleased to read (in the preface) that great effort was made to 'bridge the gap between academic work and practical work'."

— Todd Batzel, Pennsylvania State University, Altoona College Division of Business and Engineering

"I especially like the practical focus of the book. In these days of reduced laboratory experience, the student may not get a chance to experiment with real transformers, motors and generators. While the very practical information stressed here is not a perfect substitute for hands-on work, this information will be very valuable."

— Herman Hill, Ohio University, School of Electrical Engineering and Computer Science

"I am glad to see that [the second edition] retained all of the wonderful coverage of fundamentals and engineering practice that made [the] first edition so valuable, and I know that future generations of students will benefit from the book like myself...The textbook proper can definitely serve an undergraduate course on Electric Machines, and the textbook with the web resources can be used at the graduate level. [The] textbook offers numerous insights into the practice of engineering. The explanations and figures are thoughtful and beneficial to the learning process. The in-chapter examples, exercises, and end-of-chapter problems are exceptional; in that, they not only support an understanding of the subject matter, but offer practical insight into applications. [This] textbook is unique because it seamlessly blends fundamentals and engineering practice. It is a 'must have' for students and practicing engineers alike."

— Dr. Frank Mercede, Villanova University
