Abstract

Possibilities of improvement of operational and dielectric properties of epoxyamine electrical insulating varnish coatings for electric motor windings with determination of optimal ratios of mixture components are considered. It is established that curing with new aminosiloxanes improves the dielectric and operational characteristics of the varnish compositions. The possibility of using aminosiloxanes as hardeners for epoxydian resins recommended for use as a varnish coating for electric motor windings is experimentally studied. The adhesive strength and heat resistance of the developed epoxyamine varnish coatings are investigated. The use of aminosiloxanes leads to an increase in the adhesive strength and heat resistance of varnish compositions.
