A new approach To stator impregnation

The new family of solventless varnishes and the new application process described in this paper will alter the concepts of the varnish processing of rotating electrical equipment. A summary of the benefits which may be obtained from the new solventless varnishes and the associated processes include sharply reduced processing time for the treatment of both rotors and stators, minimum equipment investment and floor space, process savings, reduced fire hazard and a multipurpose product which will allow a manufacturer to coat, impregnate and encapsulate rotating electrical equipment to produce a superior product.
