Features: Compared to electrically excited motors, permanent magnet motors, especially rare-earth permanent magnet motors, have significant advantages such as simple structure, reliable operation; small size and light weight; low loss and high efficiency; and flexible and diverse shapes and dimensions. As a result, they are widely used in nearly all fields, including aerospace, defense, industry, agriculture, and daily life. This book is a compilation and summary of the research and development achievements of the Special Motors Research Institute of Shenyang University of Technology over the past decade. It elaborates on the research and analysis methods suitable for computer application in permanent magnet motor research, primarily using equivalent magnetic circuit analytical solutions combined with modern design methods such as electromagnetic field numerical calculations. The book analyzes the operating principles, structures, calculation methods, and design characteristics of various basic types of modern permanent magnet motors. It focuses on rare-earth permanent magnet motors, but the fundamental content is equally applicable to other types of permanent magnet motors such as alnico and ferrite permanent magnets. The book strives to adhere to the principle of integrating theory with practice, clarifying basic principles and concepts while providing essential formulas, reference data, and curves needed for design, manufacturing, and operation. It also aims to reflect the new technologies, achievements, and practical application trends of the permanent magnet motors discussed. Four basic types of permanent magnet motors are accompanied by practical electromagnetic computer programs and examples, and two permanent magnet motor electromagnetic computer source programs are provided. This book serves as a reference for scientists and engineers engaged in the research, design, manufacturing, testing, and operation of permanent magnet motors; it can also be used as a graduate textbook for electrical and electrical engineering programs in universities; and it is suitable as a teaching reference book or continuing education material for faculty and students in electrical engineering and automation control disciplines.
