Description

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.

Reviews

"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."
