Abstract

PURPOSE: To make a metallic mold unnecessary by using insulation layers of prepreg material set inside and outside of coil wound around with a conducting wire as a mold at the stage of filling a molding resin.
CONSTITUTION: Prepreg material 3 preparedly impregnating an epoxy resin in sufficiently dried glass cloth, etc., is wrapped around a coil former 2 as inside insulation layer. After winding coil 4, prepreg material 5 is wrapped as outside insulation layer. Then, these product is set on the pedestal 7 and epoxy resin is poured 71 and filled betwen layers 3 and 5 and hardened by heating. Expensive metallic mold is not necessary by this method.
