Electrical winding assembly constructed by (A) winding an electrical conductor into a plurality of radially-spaced layers about an axis, (B) disposing electrical insulating sheet material, which has dry, heat-reactive resin material disposed at discrete areas on at least one side thereof, between the layers of the electrical conductor, (C) applying a slurry formed of solid, heat-reactive resin particles suspended in a non-aqueous liquid carrier, wherein the liquid is chemically inert for the resin particles suspended therein so as not to dissolve or enter into a reaction with the resin, at predetermined locations between certain of the layers of the electrical insulative material and the electrical conductor and (D) heating the electrical winding assembly at a predetermined temperature for a predetermined period of time sufficient to volatize the non-aqueous liquid carrier and to cause the resin on the electrical insulative material and in the slurry to soften and form cohesive bonds between adjacent layers of the electrical insulative material and the electrical conductor as it polymerizes to a solid state. |
