Abstract: A stator for a rotating electric machine has a stator core provided with a plurality of slots arranged in a circumferential direction of the stator core, and a stator winding that is wound around the slots. The stator winding is configured of a plurality of covered conductor linear portions. The covered conductor linear portions are each provided with an exposed portion formed on an end. The plurality of covered conductor linear portions are each joined to another covered conductor linear portion at the exposed portion, and the conductor joined portion is covered by an insulator at least in a range that includes an end portion of the insulation cover. The insulation cover covers the conductor, in an adhered state there to, and has a low-adhesion portion that that is either adhesive-free or has a lower adhesive strength than other parts on the conductor and is distanced from an end portion.

Abstract: A rectangular wire having: a multilayer conductor member constructed by stacking, in a thickness direction, a rectangular metallic conductor that has a layer of a first thermoplastic resin formed on the outer periphery thereof, the first thermoplastic resin being a non-crystalline resin having no melting point or a crystalline resin having an amide bond; and a layer of a second thermoplastic resin having a melting point of 300° C. or more on the outer periphery of the multilayer conductor member.

Abstract: An electric conductor is provided for forming a coil upon being bent. The electric conductor includes a pair of electric conductor wires and an insulating coat. The electric conductor wires each have a substantially rectangular cross section and are arranged in alignment with each other in an alignment direction. The alignment direction is perpendicular to corresponding sides of the substantially rectangular cross sections of the electric conductor wires; the corresponding sides have the same length. The insulating coat is formed on outer peripheral surfaces of the electric conductor wires. The insulating coat has a thick portion formed at a boundary between the electric conductor wires. The thick portion is thicker than and protrudes outward from other portions of the insulating coat which adjoin the thick portion in a circumferential direction of the electric conductor.

Abstract: According to one embodiment, an insulated wire is disclosed. The insulated wire includes an aluminum conductor, and a first insulating film provided on the aluminum conductor. The first insulating film is made of a first polyimide obtained by reacting an acid component containing 50 mol % to 90 mol % of 3,3?,4,4?-biphenyl tetracarboxylic acid dianhydride, 5 mol % to 20 mol % of 3,3?,4,4?-benzophenone tetracarboxylic acid dianhydride, and 5 mol % to 40 mol % of pyromellitic anhydride with a diamine component containing 4,4?-diaminodiphenyl ether.
