摘要： A stator includes a stator core having a plurality of slots in a circumferential direction about an axis and having an end surface in a direction of the axis, and a first coil and a second coil of different phases which are wound on the stator core in distributed winding. A winding factor is 1. Each of the first coil and the second coil has winding portions, the number of which corresponds to the number of poles. The winding portions include first and second winding portions adjacent to each other in the circumferential direction. The first and second winding portions are inserted into one slot of the plurality of slots and extend from the one slot to both sides in the circumferential direction on the end surface. The first and second coils are annularly disposed in different positions in a radial direction about the axis on the end surface.

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.
