ABSTRACT:
Methods of constructing a void-free, cellulose-free electrical winding insulated with a solid resinous insulation. The method includes forming a plurality of conductor turns on a substrate, with each conductor turn being immersed in liquid resinous insulation as it is formed, to provide a void-free intermediate structure. The void-free aspect of the intermediate structure is maintained up to and including the final step of the method by building solid insulation, thin layer upon thin layer, from the liquid resinous insulation, while the conductor turns are being formed, with the solid insulation, as it is formed, providing a solid substrate for the continued application of liquid resinous insulation and subsequent conductor turns of the winding.
