Abstract

The invention provides an insulator, a motor and a compressor, which inhibits stress applied to a wire when equipping wires inside and outside an insulator wall surface of the motor stator and prevents damage owing to press and vibration to an angle portion. The insulator has a circular periphery wall portion (46w) which extends along the shaft direction of a core portion and forms a groove (46xS) allowing the wire (43b) to pass. An inclination surface (51) which is inclined in the racial direction of the core portion relative to the axial direction of the core portion is formed in one wall portion (46wL) in wall portions on two sides of the groove (46xS) in the periphery wall portion (46w) and on the periphery side of the end portion opposite to another wall portion (46wR). The wire (43b) is disposed along the inclined surface (51).

Description

technical field [0001] The present invention relates to insulators for electric motor stators, electric motors and compressors. Background technique [0002] Conventionally, various compressors have been developed that compress refrigerant using the rotation of an electric motor. For example, there is a scroll compressor that compresses refrigerant in compression chambers formed between a fixed scroll and a movable scroll each having a spiral lap. In this compressor, an electric motor is used to rotate the movable scroll eccentrically. [0003] In such a motor, for example, a power supply and each winding section are connected to supply current from the power supply to the winding section (coil). In addition, for example, in order to provide a neutral point, each winding part is connected separately. [0004] Patent Documents 1 to 3 disclose insulators provided with terminals for such connection. [0005] In addition, Patent Document 4 discloses an insulator that enables...
