## Contents


Preface

Electric machines are some of the most important technological pillars in the development of modern societies. They were first used in multiple rotatory-based applications in industry, and later found application in the energy and transport sectors. As such, the research and developments around electric machines are constantly evolving. Scientific and technological efforts in electric machines are being applied in three main areas: (1) electric motor technologies (AC/DC, synchronous/asynchronous induction, permanent magnet, reluctance, etc.), (2) supervision and maintenance strategies (fault detection, condition-based monitoring, predictive maintenance, etc.), and (3) control schemes (vector control, fault-tolerant approaches, etc.). Each field of application has its own specifications in terms of electric motor requirements and performances.

This book presents original research work on electric machine technologies and applications.

The first section discusses the maintenance of electric motors, combining signal processing and artificial intelligence as a strategic methodology from which novel fault detection and identification schemes are being deployed. It also reviews predictive maintenance strategies over new industrial communication architectures, the integration of new industrial information drivers from text sources, and the effects of some renewable energy-based power

The second section focuses on electric motor controls and their suitability to different motor technologies. It discusses direct torque control and Lyapunov-based sensorless schemes in switched reluctance, squirrel-cage induction, and permanent magnet synchronous machines

The chapters in this book highlight a diversity of new trends in electric machines, including electric motor technologies, supervision and maintenance strategies, and control schemes.
