Abstract:
A method for providing electrical and mechanical protection for a coil winding, said method comprising the steps of:inserting said coil winding into an auxiliary spacing apparatus having an essentially U-shaped cross-section comprising three sides, each side being perpendicular to each other, said auxiliary spacing apparatus having projections on all three sides of said essentially U-shape auxiliary apparatus; inserting said auxiliary spacing apparatus containing said coil winding into a metal mold having a three-faceted essentially U-shaped cross-sections forming a circular or oval cutout in a surface of said metal mold, each of said projections on each of said three sides of said auxiliary spacing apparatus contacting respective ones of said three facets of said essentially U-shaped cross-sections of said cutout of said mold resulting in exterior surfaces of said coil winding being equidistant from surfaces of said cutout of said three-faceted metal mold; and injecting resin molding into said mold having said auxiliary spacing apparatus and said coil winding to form a uniform thickness insulation layer about said coil winding.
