Electric Motors and Drives - Austin Hughes - 3rd Edition

Electric Motors and Drives – Austin Hughes – 3rd Edition

Electric Motors and is intended for non-specialist users of electric motors and , 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 to select the right technology for a given job. Austin Hughes’ approach, using a minimum of maths, has established as a leading guide for engineers, and the key to a complex subject for a wider readership, including technicians, managers and students.
