الوصف
An electric drive is the electromechanical system that converts electrical energy into mechanical motion, working together with the driven object—such as machine tools, industrial equipment, vehicles, home appliances, and medical or domestic devices. This book is designed for secondary-level and university-level learners in electromechanical fields, including bachelor’s and master’s students, and also for technicians and engineers. It introduces the basic laws governing driving and driven systems, dividing complex behavior into simpler parts and developing models from ideal linear assumptions toward distributed, nonlinear, and non-stationary effects. Topics include electric-drive properties, efficiency, universal machine modeling, motor types and drives, scalar and vector control methods, and practical issues in speed/torque regulation and dynamic performance.
