Features: Brushless DC motor is a new type of DC motor that uses electronic commutation technology to replace the brush commutation of traditional DC motors. It has the advantages of high operating efficiency, large starting torque, wide speed regulation range, and linear mechanical characteristics of general DC motors, as well as the features of simple structure, reliable operation, and easy maintenance of AC motors. Since the 1970s, with the successive emergence of high-performance power electronic devices and high-performance magnetic materials, the performance of brushless DC motors has been greatly improved, expanding its application scope across various fields and becoming increasingly widespread. Since the first edition of this book was published in 1996, it has been well-received by a broad readership and has been reprinted multiple times. This revision retains the fundamental principles, magnetic circuit structure, stator winding characteristics, design calculations, and control methods of brushless DC motors from the first edition, with only minor modifications and supplements. Additionally, incorporating the author's recent research achievements, two new chapters (Chapter 6 and Chapter 7) have been added, focusing on the applications and miniaturization of brushless DC motors in various fields. This book is a specialized monograph that closely integrates theory and practice, making it suitable for intermediate and advanced technical personnel, as well as university teachers and students, as a reference.
