Description

Technical Field

[0001] The utility model belongs to the technical field of motor stator protection, in particular to a compressor motor stator with a lead side protection cover. Background Art

[0002] In the process of automatic winding of the compressor motor, flying wire is adopted. The enameled wire bridge wire on the lead side is wound on the frame and is completely leaking, which can easily cause insulation failure and damage to the enameled wire of the bridge wire. Therefore, in order to protect the bridge wire and increase the insulation safety, a new insulating cover is added to protect the enameled wire. The existing protection cover is designed to completely cover the enameled wire on the lead side. Excessive cover material causes waste. The cover is designed to completely cover the enameled wire. The refrigerant flow cannot directly contact the enameled wire, and the effect of taking away the temperature of the motor enameled wire is reduced. The motor temperature rises, resulting in increased motor copper loss, reduced efficiency, and reduced life. Utility Model Content

[0007] Through the above technical scheme, through the setting of the annular insulating plate, while ensuring that the bridge wires exposed on the edge and top of the upper frame can be protected, the annular insulating plate only covers the protective bridge wires, and thus will not affect the cooling effect of the refrigerant flow on the wire package, thereby ensuring the cooling effect of the refrigerant on the motor and improving the cooling efficiency, ensuring the durability and life of the motor, and can also reduce the material for making the insulating protective cover, thereby reducing costs; in addition, by making the outer diameter value of the annular insulating plate not exceed the outer diameter value of the stator core, it is to ensure the subsequent electronic assembly effect, and by making the inner diameter value of the annular insulating plate greater than or equal to the inner diameter value of the upper frame, it is to avoid blocking the refrigerant from cooling the motor enameled wire coil, thereby improving the cooling efficiency of the motor and ensuring its service life.

[0008] Furthermore, a plurality of flying wire grooves with the same structure are vertically opened at the top of the upper frame, a plurality of strip grooves are arranged at intervals along the outer edge of the upper frame, and the bridge wires are arranged along the strip grooves.

[0009] Furthermore, the series-connected stator coils are externally connected with three-color wires, a wire slot suitable for the three-color wires is provided at the top of the first insulating plate, and a first notch corresponding to the wire slot is provided on the second insulating plate.
