Claims

[Scope of utility model registration request]

(1) A plurality of coils each made of a conductor and an interlayer insulating material are stacked in the axial direction so as to maintain an insulating distance between the coils, and the winding is integrally cast with a thermosetting mold resin. In a molded winding wire in which conductive connection parts such as connection leads and connection terminals are embedded within a predetermined angular range of a molded resin layer on the outer circumference of the wire, a thermosetting composite insulation having a higher thermal conductivity than the molded resin is used. The opening is in the angular direction where the conductive connection part is arranged. A resin molded winding wire, characterized in that inter-coil insulating plates in the form of circular discs are interposed between the coils.

(2) Utility Model Registration The resin-molded winding according to claim 1, wherein the inter-coil insulating plate is made of a cured mold resin containing a larger amount of inorganic filler than the mold resin layer.
