  • Insulation System - an overview | ScienceDirect Topics

    Common insulation systems today are classes A, B, F and H having temperature limits of 90, 130, 155 and 180 & C respectively. Motor insulation life is generally considered to be halved for every 10 & C rise up to these limits. In addition to thermal device protection provided in the starting equipment motors may also have thermistors embedded in their windings in the areas of anticipated hot spots.
