  • Publication number: 20050104252
    Abstract: An insulated coil for electric rotating machinery, according to the present invention is manufactured based on a method of manufacturing the insulated coil for an electric rotating machinery, which includes the steps of taping a mica tape on a coil conductor to mold an insulating layer, impregnating the coil with resin under vacuum and pressure condition, attaching a molding jig on the coil impregnated with the resin, and then heating the resin with which the coil is impregnated, to cure the resin, thus manufacturing the insulated coil. The mica tape taping step, a heat-shrinkable tape taping step, the impregnating step under vacuum and pressure, the resin heating/curing step utilizing a liquid heating compound and a molding jig-disassembling/finishing step are carried out to manufacture the insulated coil.
