Problems solved by technology

[0004] In the case where aluminum wire is used for the stator winding, the adhesion between aluminum and the insulating coating is worse than that between copper and the insulating coating, so short circuits may occur due to peeling off of the insulating coating
[0005] In particular, when the varnish dipping treatment is performed on the coil of the motor, the varnish is dried by heating, so an oxide film is easily formed on the surface of the aluminum, and the insulating coating is easily peeled off.
Therefore, in the case of using aluminum wire for the stator winding, there is a problem that it is difficult to guarantee the quality

Embodiment Construction

[0032] Hereinafter, embodiments of the present invention will be described in detail. In addition, in the following description, the case where the compressor is a scroll compressor is demonstrated as an example, but the type of compressor is not limited to a scroll compressor.

[0033] figure 1 It is a vertical cross-sectional view of a scroll compressor as a compressor of the present embodiment. figure 2 It is a cross-sectional view of a scroll compressor as a compressor of the present embodiment. As shown in the figure, the scroll compressor 1 is an internal high-pressure type compressor. Such as figure 1 As shown, the scroll compressor 1 includes: a vertical cylindrical airtight container 2 formed of a steel plate; a motor (electric component) 20 accommodated in the inside of the airtight container 2; The rotary shaft 22 of the 20 drives the scroll compression member 10 . Furthermore, figure 1 The vertical scroll compressor 1 shown is figure 1 the top of the figur...

Abstract

A compressor motor (20) is provided with: a lead wire; a stator (23) around which a stator winding (24) comprising a copper-clad aluminum wire having an insulating coating film on the surface is wound; and a rotor (25) that rotates inside the stator (23). Furthermore, the compressor motor (20) is provided with a conductive connection member having a protrusion on the inner surface, and the lead wire and the stator winding (24) are crimped by the protrusion. In addition, the protrusion of the connection member breaks through an insulating coating film of the stator winding (24) made of a copper-clad aluminum wire and a copper layer to reach an area of aluminum.

Description

technical field [0001] The present invention relates to a motor for a compressor, a compressor and a method for manufacturing the motor for a compressor. Background technique [0002] Conventionally, a compressor is used in which a compression element such as a scroll type or a rotary type and an electric motor (electric element) are accommodated in an airtight container, and the compression element is driven by the motor to compress refrigerant. The electric motor includes a stator in which a stator winding is wound around an iron core, and a rotor rotating inside the stator, and the compression member is rotationally driven by a rotating shaft fitted to the rotor. [0003] In conventional motors for compressors, two types of copper wires and aluminum wires are used as stator windings, and a refrigerant-resistant insulating film is coated on the copper wires or the aluminum wires. In general, copper wire is used for the stator winding when electrical conductivity is import...
