Summary: This textbook deals exhaustively with electrical machines and provides examples of their application to modern electromechanical drive systems. Some everyday examples of these applications can include: a cooling fan driven by electric motor (usually a single-phase induction motor), a washing machine drum driven by a PM brushless motor or SRM, an electric screwdriver driven by an AC brush motor, a wind turbine with induction or PM brushless generator, etc. Most of the material in this book has been classroom-tested, with very successful results. Each chapter contains a minimum 10 numerical examples to help enforce new information, while exploring technical problems and their possible solutions. In addition to standard electrical machines, the content offers students an opportunity to familiarize themselves with modern electrical machines.
