Abstract
A method of impregnating electric machinery (32) containing windings with a resin (46) in accordance with the invention includes providing a vessel (30) for containing the electric machinery and an impreganting resin with the vessel having an interior volume (40) in contact with an exterior surface (42) of the electric machinery to be contacted with resin to impregnate the windings; heating the vessel containing the electric machinery to a temperature sufficient to reduce viscosity of the resin upon contact with the machinery to promote flow of resin into contact with the windings; contacting the heated vessel and electric machinery with the resin with the heated electric machinery reducing the viscosity of the resin with the reduced viscosity resin flowing into contact with the windings to be impregnated; curing the resin within the vessel to cause the resin to be retained in contact with the windings and removing the electric machinery from the vessel.
