Abstract

There is a need for an efficiency estimation tool that can be used easily and with a reasonable level of confidence so that motors can be evaluated for replacement with energy-efficient motors in a simple, cost-benefit analysis. In addition, it would be desirable to assess the condition of the motor at the same time the efficiency is being measured. This report provides an overview of various methods for estimating the operating efficiency of a motor without actually removing it from service and testing it on a dynamometer; the report also provides a concept for including a motor condition diagnostic into the same tool. The efficiency estimation and motor diagnostic tool needed for the cost-benefit analysis must be easy to use, without disrupting the operating process and must provide reasonable accuracy.
