This is an introductory work explaining the principles, construction, and use of electric motors and their associated drive controls. It starts from basic physics and progresses to discuss state-of-the-art topics such as piezoelectric motors and vector control. It is largely non-mathematical in its approach and provides an uncluttered overview of the subject, easily accessible to beginning students in electrical and electronic engineering as well as engineers and scientists from other disciplines. This authoritative text is fully illustrated with precise, clear diagrams and photographs.
