Abstract

PURPOSE: To easily design and prepare this resin mold coil, by forming a cooling duct while providing it with elasticity to some extent.
CONSTITUTION: A coil conductor 12 is wound on coil formers 11 through interstage insulating paper 13. A plurality of duct forming portion materials 14 and a plurality of duct materials 15 are arranged around the conductor, and the coil conductor 12 is further wound on the materials 14, 15 similarly as a coil 2 at the outside, thus making up a coil portion. In this case, the duct meterials 15 are disposed to the middle of the adjacent portion materials 14, and the portion materials 14 consist of airtight matter, such as, a polyester film, etc., have hollow portions and are built up in approximate baggy shapes that one ends are under opening conditions. The duct materials 15 are cylindrically made up by compound, etc. Liquids are filled in the portion materials 14 and hermetically sealed, and the duct materials 15 are extracted. The coil portion is set to a metal mold, and mold resin is injected and heating hardened. Adverse effects exerted on the coil of hardening contractile force can be softened because the duct forming portion materials 14 have elasticity. After resin hardens, the sealing-up of the portion materials 14 is broken and the portion materials are removed.
