Paperback. Zustand: New. Print on Demand. This book explores the speed control of induction motors used for rolling mill service, a topic of great interest to the steel industry. The author provides a thorough examination of common speed control arrangements, including rheostat or secondary control, primary or voltage control, frequency changers, multi-speed motors, and cascade or concatenated control. The book also delves into early regulating systems, such as the Kramer system and the Scherbius system, and discusses their advantages and limitations. Additionally, it explores recent regulating systems, including the synchronous converter method and the modification of the Scherbius system, highlighting their significance in double-range regulation. The book concludes with a comprehensive examination of starting and controlling apparatus, covering both squirrel-cage motors and form-wound motors, providing valuable insights for engineers and technicians working with induction motors in rolling mill applications.
