Standard

In this IEEE standard thermal limit curves for induction machines are defined. A procedure is established for the presentation of these curves, and guidance for the interpretation and use of these curves for machine thermal protection is provided This guide applies to three-phase squirrel cage induction machines. 250 hp (200 kW) and above. It is intended to be used for machines designed for specified load and application conditions. However, it may also be used for smaller, general purpose machines if application and load conditions are specified.

620-1981 - IEEE Trial Use Guide for Construction and Interpretation of Thermal Limit Curves for Squirrel-Cage Motors Over 500 hp
April 16, 1981 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

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 curves for large squirrel-cage motors defined as those motor ratings bu...
