FIELD: electrical machines.
SUBSTANCE: invention relates to a coating composition for an electrical steel sheet, to an electrical steel sheet, a laminated core and a rotating electrical machine. The electrical steel sheet used for the laminated core has, on the surface of the base steel sheet, an insulating coating applied with an electrical steel sheet coating composition. The coating composition for electrical steel sheet contains epoxy resin, epoxy resin hardener and elastomer-modified phenolic resin, wherein the amount of elastomer-modified phenolic resin is 10-100 weight parts per 100 weight parts of epoxy resin.
EFFECT: ensuring the magnetic properties of the electrical steel sheet and its heat resistance, as well as the adhesion strength between electrical steel sheets even at high temperatures.
