Features: This book primarily elaborates on the working principles, structural characteristics, basic electromagnetic and energy relationships of DC motors, transformers, and three-phase asynchronous motors. It focuses on analyzing the mechanical characteristics of separately excited DC motors and three-phase asynchronous motors, as well as their starting, speed regulation, braking principles and related calculations. Additionally, it briefly describes the structure, working principles, and basic characteristics of single-phase asynchronous motors, synchronous machines, and control motors. It then provides a concise introduction to the fundamental knowledge of motor power selection.
While ensuring the content is sufficient, the book minimizes theoretical depth, avoids complex mathematical derivations, simplifies some intricate calculations, and enhances physical concepts to make the material more accessible and easy to understand. At the same time, it incorporates practical examples, exercises, and thought questions from industrial applications to broaden knowledge and deepen understanding of the course. This book is suitable for vocational schools offering electrical operation and control programs. It can also serve as a textbook for "Fundamentals of Motors and Drives" courses in electrical disciplines at vocational schools, such as mechatronics. It also holds reference value for engineering technicians engaged in motor and power technology work.
The graphical symbols, textual symbols, quantities, units, and related motor and transformer standards used in this book adhere to the latest national standards.
