This book reports the state of the art of energy-efficient electrical motor driven system technologies, which can be used now and in the near future to achieve significant and cost-effective energy savings.

This document assists in establishing an energy management plan, identifying energy savings opportunities, and designing a motor improvement plan.

This guidebook provides a step-by-step approach to developing a motor system energy-improvement action plan.

In industry, a motor consumes an annual quantity of electricity which corresponds to approximately 5 times its purchase price, throughout its whole life of aroun~ 12 to 20 years. Motors are by far the most important type of electric load.

Completely revised and expanded, the book reflects the recent state of the field, as well as recent developments in control electronics, the economics of energy-efficient motors and systems, and advanced power electronic drivers.

Electric motor-driven systems are estimated to consume over hlf of all electricity in the United States and over 70% of all electricity in many industrial plants.
