Features: The operation of production machinery driven by electric motors is called electric traction. In modern production, most production machinery adopts electric traction, such as various fans, pumps (water and oil), machine tools, cranes, rolling mills, transport machinery, chemical machinery, textile machinery, printing machinery, etc. According to the type of motor, electric traction is divided into DC electric traction and AC electric traction. This book mainly introduces the principles of AC and DC motors and the content of AC and DC electric traction. The book is divided into 9 chapters, which respectively introduce the motion equation of electric traction systems, the magnetic circuit, operating principles, working characteristics, and mechanical characteristics of DC motors; the starting, braking, and speed regulation of DC motors; the operating principles, operating characteristics, and connection group numbering of transformers; the windings, electromotive force, and magnetic flux of AC motors; the principles, working characteristics, and mechanical characteristics of induction motors; the starting, braking, and speed regulation of induction motors; the steady-state operation, starting, and speed regulation of synchronous motors, permanent magnet synchronous motors; and the selection of motors in electric traction systems. At the end of each chapter, there are review questions and exercises for review and practice. This book can be used as a textbook or reference book for automation majors, electrical engineering majors, and mechatronics majors in ordinary universities and adult universities, as well as for relevant technical personnel to study and reference.
