Test of thermal stability of magnet wire enamel

摘要

TESTS are developed to predict the behavior of a material in service. The purpose of the twist aging test is to accurately predict the life of a magnet-wire enamel-impregnating-varnish insulation system in service with a minimum expenditure of time, labor, material, and equipment. This is accomplished by using a number of easily constructed samples subjected to accelerated aging and evaluation.1
