This book is intended to be a text book on “Electromechanical Energy Conversion” for the undergraduates of electrical and electronic engineering students of universities and colleges. Therefore the level and amount of the knowledge to be transferred to the reader is kept as much as what can be transferred in one academic semester of a university or college. Although the subject is rather classical and somehow well established in some respects it is vast and can be difficult to grasp if went in to details. In this book it is aimed to be as short, lean and as easily understandable as possible with minimum of wording and maximum of drawings, figures and tables. A course on “electromechanical energy conversion” is a necessity in all universities and colleges entitled to grant a licence for electrical engineering. This book is aimed at meeting the requirements of this essential subject of electrical engineering by providing information just as much as it is necessary to complete the course.

A compact chapter is included with figures and tables on energy and the restraints on its production brougth about by the climate change of the planet. A new approach has been tried for some of the old subjects like magnetic circuits and electrical machines together with todays much used motors.

About the Author

Zeki Uğurata KOCABIYIKOĞLU received his BEng. and PhD Degrees in electrical engineering from the University of Sheffield UK. After receiving his PhD degree he worked for the “Iron and Steel Works in Karabuk Turkey” for 5 years and finally moved on to ASELSAN-Ankara, one of the leading defence electronics companies in Turkey. While working 28 years for the company he held several managerial positions. In his last 6 years he carried on as the vice president and “Head of Communications Division” of the company. After retiring he lectured for more than 10 years on “Electromechanical Energy Conversion” as well as “Circuit theory” “Industrial Electronics” and “Industrial Management” in several universities in Turkey. He is currently lecturing in TOBB Economy and Technology University in Ankara Turkey.
