Demand-side management opportunities through the use of energy-efficient motor systems

The key issues related to efficient motor systems operation are presented, with a particular emphasis on electronic adjustable speed drives (ASD), due to their comparatively larger potential for savings. The potential for savings associated with the use of ASD in the residential, commercial, and industrial sectors are presented. With ASD it is estimated that one-fifth of the drive power consumption can be saved, that, is over 250 TWh/yr. The combined use of ASD with other efficient motor technologies can increase the savings to 30%. Research, development, demonstration, and training options are proposed which can significantly expand the cost effectiveness, performance, and scope of efficient motor systems applications.<
