Abstract

PURPOSE: To prepare the title coil of high reliability by laying the duct forming material, which is an airtight bag filled up with granular material, between the first and the second coils, injecting and hardening resin, and removing granular material to form a cooling duct.
CONSTITUTION: A coil conductor 15 is wound arround by turns on a coil winding mold 14 through interstage paper 16 and after a prescribed number of windings a duct forming material 10 is placed followed by further winding thereon the coil conductor 15 thus to form the coil. This duct forming material forms a bag with one open end with a relatively heat resisting and airtight duct forming crust 11 e.g. polyester film etc. and a tacky tape 12, and after filling up its inside with granular material 13 such as silica etc., the one open end is sealed to form itself. This coil is inserted into the metallic mold for molding which has been treated by mold releasing, then mold resin is injected, heat hardened and by hardening or by removing the duct forming material 10 to prepare the resin mold coil having a cooling duct.
