Paperback. Condición: New. Print on Demand. This book explores the phenomenon of sparking in single-phase commutator motors, a subject of critical importance in their design. The author, an expert in electrical engineering, provides a comprehensive analysis of the problem, discussing its origins, causes, and potential solutions. The book begins by exploring the fundamental concepts of sparking and introduces the concept of sparking voltage, a key metric in evaluating commutation performance. The author then delves into the various factors that influence sparking voltage, including the reactance voltage, external voltage, and contact resistance between brushes and commutator. The author also examines the impact of specific design choices on sparking, such as the number of commutator segments, brush width, and the use of auxiliary poles or compensating windings. Detailed calculations and examples are provided to illustrate the effects of these factors and guide readers in optimizing motor design. Throughout the book, the author emphasizes the importance of understanding the underlying principles of sparking to effectively prevent or minimize it. This in-depth exploration makes this book an invaluable resource for engineers and researchers working in the field of electric machines and motor design.
