Abstract

PURPOSE:To increase productivity and to increase radiant effect and space occupancy rate, by a method wherein epoxy group powder insulation is applied to the tooth section of a core and after treating earth insulation, a refrigerant-resistance and self- fusing enamel wire is wound on the tooth section of the core to eliminate a varnish impregnation treatment process. CONSTITUTION:Epoxy group powder insulation is previously applied to the tooth section of a core to form an earth insulating layer and a coil made by winding a double structure self-fusing enamel wire having a refrigerant-resistance semi-cured layer is mounted on the slot section of the core. And the coil is heated by using a coil molding mold to integrally harden the semi-cured enamel layer. In this way, radiant effect and space factor are improved comparing with the case where a film is used for earth insulation and a varnish impregnation treatment process also becomes unnecessary, accordingly, productivity and quality are improved and durability is also enhanced.
