Problems.Full-text restricted to subscribers or individual document purchasers.Electromechanical drive systems have both electrical and mechanical processes. Designing these systems involves many factors like steady-state performance, braking, speed control, overloads, ambient conditions, and mechanical coupling. This textbook comprehensively covers the fundamentals of electromechanical drives, combining theory and analytical studies. It is divided into three main parts: mechanical (torques, masses, inertia), electrical (DC, induction, and synchronous machines), and motor selection (rated torque, power, and thermal stress capacity). Aimed at advanced students majoring in electrical or mechanical disciplines, this 15-week course material is based on extensive teaching experience. It includes practical examples, detailed solutions, and drill problems. Additionally, it serves as a valuable reference for design and supervising engineers in various industries.Advanced students studying courses on electric drives or electromechanical drives. This is a required topic for senior and graduate level students majoring in electric power systems and the material can be covered in one academic semester (15 weeks).Also available in print.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.Zivan Zabar is Professor Emeritus of Electrical and Computer Engineering at the Tandon School of Engineering, New York University, USA. His areas of expertise are electric power systems, electric drives, and power electronics.Title from PDF title page (viewed on February 1, 2025).
