Abstract: A method for manufacturing a compressor includes fixing a stator core to an inside of a barrel via a resin member by shrink fit. An outer peripheral surface of the resin member is a first joining surface. A surface in contact with the first joining surface on an inner peripheral surface of the barrel is a second joining surface. The fixing the stator core to the inside of the barrel includes joining the first joining surface to the second joining surface. Upon joining, to the second joining surface, an intermediate portion of the first joining surface between a first end and a second end facing each other, spaces between the first joining surface and the second joining surface are formed between the first end and the intermediate portion and between the second end and the intermediate portion.

Abstract: An insulated wire, containing: a conductor; a foamed insulating layer; and an unfoamed filled layer on the outer circumference of the foamed insulating layer, in which the filled layer contains a partial discharge resistant material, which insulated wire has all of high partial discharge inception voltage, resistance to partial discharge, heat resistance, and abrasion resistance (scratch resistance).

Abstract: An inverter surge-resistant insulated wire, having at least one baked enamel layer around the outer periphery of a conductor, and an extrusion-coated resin layer at the outside of the baked enamel layer, wherein a total thickness of the baked enamel layer and the extrusion-coated resin layer is 50 ?m or more, a thickness of the baked enamel layer is 60 ?m or less, and a thickness of the extrusion-coated resin layer is 200 ?m or less, wherein the minimum of tensile elastic modulus of the extrusion-coated resin layer at a range of 25 to 250° C. is 100 MPa or more, wherein a dielectric constant of an insulation layer having a combination of the baked enamel layer and the extrusion-coated resin layer is 3.5 or less at 25° C. and 5.0 or less at 250° C., and wherein a relation between dielectric constant (?1?) of the baked enamel layer at 250° C. and dielectric constant (?2?) of the extrusion-coated resin layer at 250° C. satisfies (?2?/?1?)>1.
