This book contains the papers presented at the tenth international conference on Energy Efficiency in Motor Systems (EEMODS). EEMODS' 2017 organised in Rome, Italy, by University of L'Aquila on 6-8 September 2017. This major international conference has been very successful in attracting an international community of stakeholders consumption (including manufacturers, consumers, governments, international organisations, academia and experts) dealing with motor systems (motors, drives, pumps, compressors, fans, etc.) to discuss the progress achieved in technologies, industrial applications and policies, the strategies that need to be implemented to further progress this important work. Potential readers who may benefit from this book include researchers, engineers, policymakers, and all those who can influence the design, selection, application, and operation of motor system.
