The book details the modeling, performance, design, and control of reluctance synchronous and flux-modulation machines developed for low cost and high efficiency. It covers one and three phase reluctance synchronous motors in line-start applications and reluctance flux-modulation motors in pulse width modulation converter-fed variable speed drives.

The numerous numerical design and control examples(with practical specifications) throughout the 23 Chapters of the book allow the reader deep and fast access to a practical but thorough unitary (good for comparisons) methodology in designing and control of LEMs for various applications

This book provides extensive coverage of variable speed generators in distributed generation and renewable energy applications around the world. Numerous design and control examples illustrate the exposition. Fully revised and updated to reflect the last decade¿s worth of progress in the field, the second edition adds material on doubly fed induction generator control under unbalanced voltage sags and nonlinear loads, interior permanent magnet claw-pole-alternator systems, high power factor Vernier permanent magnet (PM) generators, PM-assisted reluctance synchronous motors/generators for electric hybrid vehicles, and more.

This book explores large- and medium-power synchronous generator topologies, steady state, modeling, transients, control, design, and testing. Numerous case studies, worked-out examples, sample results, and illustrations highlight the concepts. Fully revised and updated to reflect the last decade¿s worth of progress in the field, the second edition adds coverage of high-power wind generators with fewer or no permanent magnets (PMs), PM-assisted DC-excited salient pole synchronous generators, autonomous synchronous generators¿ control, line switching parameter identification for isolated grids, synthetic back-to-back load testing with inverter supply, and more.

Alternating current (AC) induction and synchronous machines are frequently used in variable speed drives with applications ranging from computer peripherals, robotics, and machine tools to railway traction, ship propulsion, and rolling mills. This book examines the progress achieved worldwide in vector control since 1969.
