Abstract :
In the composite insulation system of a magnet-wire coating and a varnish, there is the possibility of harmful reaction between the two at elevated temperatures. Thus, there may be discontinuities in the Arrhenius curves (log of thermal life versus the reciprocal of the absolute temperature). Experimental results are given showing reactions between certain varnishes and certain combinations of polyester/polyamide-imide enamel systems.
