Determining Motor Load & Efficiency from Measured Data

A. Bhatia, B.E.

Those familiar with motors know that just because a motor has a nameplate rating of 50 horsepower doesnÂ’t mean that it actually delivers 50 horsepower to its load. The load itself determines the horsepower needed to drive it, and whatever motor is connected to that load will try to deliver the power that the load demands. Spotting overloaded motors can help you avoid motor burnouts whereas spotting underloaded motors can lead to downsizing and reduced operating costs.

This 3-hr course presents a brief overview of some of the different ways to determine a motor's load from in-situ measurements. This course shall be useful for field engineers to select or to establish a proper efficiency evaluation method by understanding the theories and error sources of the methods.

The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
