Abstract
Electric motors are significant users of electricity in the United States. Approximately 66 percent of the total electricity in the U.S. is used by electric motors. Electronic adjustable speed drives (ASDs) can save energy, lower maintenance cost and improve product quality. By providing a variable frequency output to ac motors the speed of the motors can be controlled and matched to the process requirements. The benefits that may be derived from using ASDs are described and the type of ASDs, applications and specific case studies of ASD installations are also discussed.
