Development of a method for estimating motor efficiency and analyzing motor condition

PDF Version Also Available for Download.

Description

There is a need for an efficiency estimating 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 ... continued below

Description

There is a need for an efficiency estimating 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 a reasonable accuracy. The study reports on several efficiency estimation methods and compares them with actual dynamometer measurements of efficiency. It is found that reasonable estimates can be made without a high level of cost and disruption of the process.
