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, making its application scope extend to 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 many times. For this revision, the basic principles, magnetic circuit structure, stator winding characteristics, design calculations, and control methods of brushless DC motors retained from the first edition have been slightly modified and supplemented, combined with the author's recent research achievements. Two new chapters, the 6th and 7th, have been added, focusing on the applications and miniaturization of brushless DC motors in various fields. This book is a specialized monograph closely integrating theory and practice, suitable for intermediate and advanced technical personnel and university teachers and students to read and reference.
