This book covers the basics and the state of the art of energy-efficient motor technologies, which can be used now and in the near future to achieve significant and cost-effective energy savings. It describes recent developments in advanced motor technologies such as permanent magnet and reluctance motors. Energy-efficient motor technologies, though enabling a huge amount of electricity to be saved, still have not been widely adopted. The book presents barriers to the adoption of those technologies and features policies to promote the large scale penetration of energy-efficient technologies, describing the experiences carried out so far in different parts of the world. The volume includes contributions from relevant institutions in the European Union, North America, Latin America, Japan and New Zealand.
