Abstract

PURPOSE:To prevent the cooling of the outside molded coil from being disturbed by absorbing resin oozed due to the tightening force produced when the outside molded coil is wound, by a winding member and thus preventing the extrusion of the resin in a cooling duct. CONSTITUTION:A predetermined number of turns of coil 20 is wound on the outer periphery of an insulating layer 21, an insulating layer 22 is formed on the outer periphery thereof, and an inside molded coil 2 is thus completed. An insulating winding member 9 is wound on the outer peripheral surface of the coil 2, and a plurality of rectangular longitudinal duct pieces 4, 4... are then arranged at a predetermined interval circumferentially on the coil. Further, a winding member 10, an insulating layer 31, a coil 30 and an insulating layer 32 are formed to complete the outside molded coil 3. Subsequently, the coils 2 and 3 are heated to harden the resin impregnated into the layers 22, 32 to form one body, thereby completing the molded coil 1 formed with cooling ducts 5, 5...,.
