摘要： An aluminum wire, which is an electric wire of an electric motor of a compressor, is wound around a copper wire, which is another electric wire, at interval in the length direction. The portion around which the aluminum wire is wound is brazed with a brazing material containing a flux. Thus, the aluminum wire and the copper wire are joined together, and an electric wire joint section is formed. Insulating paper is mounted to the electric wire joint section. The inner surface of the insulating paper is brought into contact with the surface of the electric wire joint section to which a residue of the flux adheres.

摘要： A rotor core has first and second magnet insertion holes along an outer circumference, and first and second slits along an inner circumference. The first and second slits have first and second facing portions facing each other. The first facing portion has a first inner end and a first outer end. The second facing portion has a second inner end and a second outer end. An inter-slit portion is provided between the first and second facing portions and is defined by a first straight line connecting the first and second inner ends and a second straight line connecting the first and second outer ends. In a radial direction of the rotor core, a minimum distance D1 from the inner circumference to the slits, a minimum width W1 of the slits, and a length W2 of the inter-slit portion satisfy at least one of D1

摘要： The present invention provides a solvent-free varnish composition, including: a thermosetting resin (A) having two or more (meth)acryloyl groups in a molecule thereof; a thermosetting resin (B) having one or more epoxy groups in a molecule thereof; a monofunctional vinyl-based monomer having an ether bond or an ester bond; an organic peroxide having a 10-hour half-life temperature of 40° C. or more; and a curing catalyst for an epoxy resin, in which a mixed resin of the thermosetting resin (A) and the thermosetting resin (B) has an epoxy equivalent of from 500 to 5,000. The solvent-free varnish composition can be used as an insulating varnish that shows a small energy loss and requires a short curing time in its curing treatment step, and that provides a cured product that barely causes the precipitation of an oligomer or the like even when exposed to a refrigerant-based environment containing a refrigerant and a refrigerating machine oil under high temperature and high pressure.

摘要： A rotor includes a rotor core having a magnet insertion hole and a permanent magnet provided in the magnet insertion hole. The rotor core has a slit on an outer side of the magnet insertion hole in a radial direction of the rotor core. The permanent magnet is magnetized by placing the rotor so as to face a tooth around which a winding is wound, rotating the rotor in a first rotating direction from a rotational position where a center of the magnet insertion hole in a circumferential direction of the rotor core faces a middle portion between both ends of the winding in the circumferential direction and supplying electric current to the winding, and rotating the rotor in a second rotating direction opposite to the first rotating direction from the rotational position and supplying electric current to the winding.

摘要： A magnetizing method includes the steps of preparing a rotor comprising a rotor core having a magnet insertion hole and a permanent magnet provided in the magnet insertion hole, placing the rotor so as to face a tooth around which a winding is wound, rotating the rotor in a first rotating direction by a first angle θ1 from a rotational position where a center of the magnet insertion hole in a circumferential direction of the rotor core faces a middle portion between both ends of the winding in the circumferential direction and supplying electric current to the winding, and rotating the rotor in a second rotating direction opposite to the first rotating direction by a second angle θ2 from the rotational position direction and supplying electric current to the winding. The second angle θ2 is smaller than the first angle θ1.
