Reluctance Electric Machines

Electric energy is arguably a key agent for our material prosperity. With the notable exception of photovoltaic generators, electric generators are exclusively used to produce electric energy from mechanical energy. More than 60% of all electric energy is used in electric motors for useful mechanical work in various industries. This book presents the modeling, performance, design, and control of reluctance synchronous and flux-modulation machines developed for higher efficiency and lower cost. It covers one- and three-phase reluctance synchronous motors in line-start applications and various reluctance flux-modulation motors in pulse width modulation converter-fed variable speed drives.FEATURES Presents basic and up-to-date knowledge about the topologies, modeling, performance, design, and control of reluctance synchronous machines. Includes information on recently introduced reluctance flux-modulation electric machines (switched- flux, flux-reversal, Vernier, transverse flux, claw pole, magnetic-geared dual-rotor, brushless doubly fed, etc.). Features numerous examples and case studies throughout. Provides a comprehensive overview of all reluctance electric machines.

"Reluctance motor drives start to find their rightful place in the adjustable speed motor drives. This is in part due to their lower cost, ease of cooling, higher fault tolerance, and suitability for use under harsh operating and ambient condition. The book by Prof . Boldea and Prof. Tutelea offers a physically insightful approach to electromechanical energy conversion in this family of electric machines. Authors provide an in depth explanation of the electromagnetic performance, interdependence between control and magnetic design and fundamentals of design. I found this book to be a great resource for practicing engineers in industry and researchers in the academia. There is an outstanding balance between the theoretical contents and engineering aspects of design and control throughout the manuscript which makes this book an excellent choice for a graduate course in academic institutions or series of short courses for practicing engineers in the industry. I would like to strongly recommend this book for researchers and practitioners in the area of electric machines."-Babak Fahimi, Distinguished Chair of Engineering at University of Texas at Dallas, USA "I stress that this attractive book is very useful for students of electrical, mechanical, and mechatronics as well as for practicing engineers interested in the design and optimization of electrical machines and drive systems."—IEEE Industrial Electronics Magazine, March 2019 Issue

Professor Ion G. Boldea is a Full Professor of Electrical Engineering at the University Politechnica of Timisoara, Romania. He has spent approximately 5 years as Visiting Professor of Electrical Engineering in both Kentucky and Oregon, USA since 1973, when he was a Senior Fullbright Scholar for 10 months. He was also a Visiting Professor in the UK at UMIST and Glasgow University. He is a full member of the Romanian Academy of Technical Sciences, a full member of the European Academy of Sciences and Arts of Salzburg, Austria, and a full member of the Romanian Academy. He has delivered IEEE-IAS Distinguished Lectures since 2008. He has given keynote speeches, tutorial courses, intensive courses, technical consulting in the USA, South America, E.U, South Korea, and China based on his numerous books and IEEE Trans. and Conference papers over the last 45 years in the field of rotating and linear electric machines and drives for renewable energy, vehicular, industrial, and residential applications. Professor Boldea is a Life Fellow of IEEE. He won the IEEE 2015 Nikola Tesla Award for "contributions to the design and control of rotating and linear electric machines for industry applications."Professor Lucian N. Tutelea (M’07) received the B.S. and Ph.D. degrees in electrical engineering from the Politehnica University Timisoara, Timisoara, Romania, in 1989 and 1997, respectively. He was a Visiting Researcher with the Institute of Energy Technology, Aalborg University, Denmark, in 1997, 1999, 2000, and 2006, as well as the Department of Electrical Engineering, Hanyang University, South Korea, in 2004. He is currently a Professor with the Department of Electric Engineering, Politehnica University Timisoara. His main research interests include design, modeling, and control of electric machines and drives. Professor Tutelea published more than 80 papers indexed IEEE Xplore or in Web of Science with more than 400 citations.
