MOTOR/DRIVE SELECTION; Introduction; Power Range for Motors and Drives; Load Requirements - Torque-Speed Characteristics; General Application ConsiderationsReview QuestionsElectric Motors and Drives is intended for non-specialist users of electric motors and drives, filling the gap between theory-based academic textbooks and the more prosaic 'handbooks', which provide useful detail but little opportunity for the development of real insight and understanding. The book explores all of the widely-used modern types of motor and drive, including conventional and brushless D.C., induction motors and servo drives, providing readers with the knowledge to select the right technology for a given job.
