The book provides a comprehensive overview of electrical machines and their interaction in electric drive systems. It aims to explain the phenomenological understanding of today's drive systems and their components to the reader, without solely relying on purely abstract mathematical representations. Research work, years of teaching experience, and ongoing collaboration between the authors and industry have resulted in a comprehensive technical book for engineers in both study and practice, which includes numerous exercises with solutions. The book is aimed at engineers working in electrical drive technology and automation technology, as well as students of electrical engineering and mechanical engineering who are seeking a solid, complete, and accurate introduction to modern, controllable and non-controllable, automated electric drives.
