The book is designed for beginners who want to gain an initial overview of the field of electrical machines and drives. To understand these topics, one must first engage with the fundamentals of electrical engineering. Therefore, this book also includes a comprehensive introduction to the basics of electrical engineering, initially covering the electrical quantities of electric and magnetic fields, as well as direct current, alternating current, and three-phase networks. Building on these fundamentals, the book then conveys, focusing on the essentials, a basic understanding of the structure and operation of important electrical machines such as transformers, three-phase asynchronous motors, direct current motors, and three-phase synchronous generators. Subsequently, the fundamentals of power electronics are introduced, which are essential for modern variable-speed electric drives.
