Ali Emadi. Energy-Efficient Electric Motors

2004. This detailed reference provides guidelines for the selection and utilization of electric motors for improved reliability, performance, energy-efficiency, and life-cycle cost. 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. It includes five new chapters covering key topics such as the fundamentals of power electronics applicable to electric motor drives, adjustable speed drives and their applications, advanced switched reluctance motor drives, and permanent magnet and brushless DC motor drives.

Cambridge University Press, 1997. 248 p. ISBN:0521480175, 0521020328 This book deals with LEAs that convert electric energy into controlled mechanical motion of limited travel and LEGs that transform mechanical energy into electric energy. Examples range from loudspeakers and microphones to magnetically levitated material transfer in ultraclean rooms. Much of the literature on linear actuators and generators covers the principles of operation a...

Библиографический проект. In the light of new European standards of energy efficiency of electric machines, the use of line-start permanent magnet synchronous machines is set to develop greatly in the years to come. However, the starting and synchronization of these motors still remain as important challenges and need further improvements. These processes need representative models of the way the systems behave. In order to evaluate the LS-IPMSM’...

2008 John Wiley & Sons, Ltd Electrical machines are almost entirely used in producing electricity, and there are very few electricity-producing processes where rotating machines are not used. In such processes, at least auxiliary motors are usually needed. In distributed energy systems, new machine types play a considerable role: for instance, the era of permanent magnet machines has now commenced. About half of all electricity produced globa...

OECD, IEA Energy Papers No: 2011/07, 132 p ISSN:20792581 This paper is the first global analysis of the potential energy savings which could be found in electric motor- driven system (EMDS). EMDS currently accounts for more than 40% of global electricity consumption. Huge untapped energy efficiency potential was found in EMDS; around 25 % of EMDS electricity use could be saved cost-effectively, which would reduce total global electricity demand...
