scope:
This guide defines thermal limit curves, recommends a standard procedure for construction of the curves, and provides the definitions and information necessary to properly use these curves.
The guide also describes thermal limit curve* for large squirrel -cage motors defined as those motor ratings built in frames larger than the frame normally used for 500 hp, 1800r/min motors.
Purpose
The purpose of this guide is to assist in a uniform understanding of the construction, interpretation, and use of motor thermal limit curves.
