IEEE 620-2022 PDF
This guide applies to three-phase squirrel cage induction machines, 250 hp (200 kW) and above and designed for specified load and application conditions. This guide provides a consistent way to show how the thermal limit curves for squirrel cage induction machines are to be presented. Revision Standard - Active. A procedure is established for the presentation of thermal limit curves, and guidance for the interpretation and use of these curves for machine thermal protection is provided in this guide.More Standards PDF
