Description

Technical Field

[0001] The utility model relates to the technical field of motors, and more specifically, to a skeleton with an increased head wire avoiding groove. Background Art

[0002] During the process of realizing automatic winding of a compressor motor, in the form of flying wires, the winding coils and copper wires on the skeleton are prone to friction, resulting in damage to the paint layer.

[0003] The existing skeleton design does not have a skeleton with a copper wire routing groove. During the automatic winding process, it may cause abrasion and wire breakage of the copper wire, and the copper wires may come into contact with each other, generating friction and damaging the paint layer. Summary of the Utility Model

[0004] The utility model provides a skeleton with an increased head wire avoiding groove to solve the problems in the related technologies. This device solves the problem of abrasion and wire breakage caused by the mutual contact of copper wires.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] A skeleton with an increased head wire avoiding groove of the utility model includes a stator core. An upper skeleton is arranged on the stator core. The upper skeleton is arranged in a ring shape. A groove for fixing the wire head is arranged on the inner wall surface of the upper skeleton. The top surface of the groove is flush with the top surface of the upper skeleton, so that the top surface of the groove is in an open shape for the wire head to penetrate through the upper skeleton. The width of the groove is greater than the outer diameter of the wire head.

[0007] In the above solution, through the arrangement of the groove, the copper wire is placed in the groove, which can effectively avoid the friction between the copper wire and the winding coil, and avoid the wear caused by excessive friction between the winding coil and the copper wire. The groove structure is used to protect the copper wire, thus solving the problem of abrasion and wire breakage caused by the mutual contact of copper wires, greatly avoiding the wear of the copper wire, and increasing the service life of the motor.

[0008] A plurality of stator teeth protruding inward are arranged on the inner wall surface of the upper skeleton, and the plurality of stator teeth are evenly arranged circumferentially along the inner wall surface of the upper skeleton.

[0009] In the above solution, through the arrangement of the stator teeth, they are used for winding the motor coil.

[0010] The groove is arranged along the axial direction of the upper skeleton.

[0011] In the above solution, through the arrangement of the groove, it is convenient to place the copper wire in the groove, thus protecting the copper wire and facilitating wire routing.

[0012] The grooves are evenly arranged circumferentially along the inner wall of the upper skeleton. The bottom surfaces of the grooves are all flush with the top ends of the stator teeth, and the grooves are communicated with the stator teeth.

[0013] The groove width of the groove is 1.5 mm to 2.5 mm, and the groove depth of the groove is 0.5 mm to 1.5 mm.

[0014] In the above solution, through the settings of the groove width and groove depth of the groove, the copper wire can be completely placed in the groove. The groove provides sufficient space, which can avoid the copper wire from being over-stretched or compressed, reduce the mechanical damage of the copper wire, protect the integrity of the copper wire, and can better fix the copper wire, reduce the movement and vibration of the copper wire during use, thereby enhancing the stability and reliability of the motor.

[0015] Adopting the above solution, there are the following specific advantages:

[0016] 1. Since a skeleton with an increased head wire avoiding groove of the present utility model includes a stator core, an upper skeleton is arranged on the stator core, the upper skeleton is arranged in a ring shape, and a groove for fixing the wire head is arranged on the inner wall surface of the upper skeleton. The top surface of the groove is flush with the top surface of the upper skeleton, so that the top surface of the groove is in an open shape for the wire head to penetrate through the upper skeleton. The groove width of the groove is larger than the outer diameter of the wire head. Placing the copper wire in the groove can effectively avoid the friction between the copper wire and the winding coil, and avoid the wear caused by excessive friction between the winding coil and the copper wire. Using the groove structure to protect the copper wire can greatly avoid the copper wires from contacting each other, thereby causing wear and increasing the service life of the motor.

[0017] 2. A plurality of stator teeth protruding inward are arranged on the inner wall surface of the upper skeleton, and the plurality of stator teeth are evenly arranged circumferentially along the inner wall surface of the upper skeleton for winding the motor coil. The groove is arranged along the axial direction of the upper skeleton, which is convenient for placing the copper wire in the groove to protect the copper wire and is also convenient for wire routing. The groove width of the groove is 1.5 mm to 2.5 mm, and the groove depth of the groove is 0.5 mm to 1.5 mm. The copper wire can be completely placed in the groove. The groove provides sufficient space, which can avoid the copper wire from being over-stretched or compressed, reduce the mechanical damage of the copper wire, protect the integrity of the copper wire, and can better fix the copper wire, reduce the movement and vibration of the copper wire during use, thereby enhancing the stability and reliability of the motor.

[0024] As Figures 1 to 4 shown, a skeleton with an increased head wire avoiding groove of the present invention includes a stator core. An upper skeleton 1 is arranged on the stator core. The upper skeleton 1 is arranged in a ring shape. A groove 3 for fixing the wire end 2 is arranged on the inner wall surface of the upper skeleton 1. The top surface of the groove 3 is flush with the top surface of the upper skeleton 1, so that the top surface of the groove 3 is open, so that the wire end 2 can penetrate the upper skeleton 1. The grooves 3 are evenly arranged along the circumferential direction of the inner wall of the upper skeleton 1. The bottom surfaces of the grooves 3 are all flush with the top ends of the stator teeth 4, and the grooves 3 communicate with the stator teeth 4. By adopting the design of the groove 3 and placing the copper wire in the groove 3, the friction between the copper wire and the winding coil can be effectively avoided, and the wear caused by excessive friction between the winding coil and the copper wire can be avoided. The groove 3 structure is used to protect the copper wire, greatly avoiding the contact between copper wires, reducing the wear of the copper wire, and increasing the service life of the motor. The grooves 3 are arranged along the axial direction of the upper skeleton 1, which is convenient for placing the copper wire in the grooves 3, thereby protecting the copper wire and facilitating wire routing.

[0025] A plurality of inwardly protruding stator teeth 4 are arranged on the inner wall surface of the upper skeleton 1. The plurality of stator teeth 4 are evenly arranged along the circumferential direction of the inner wall surface of the upper skeleton 1 and are used for winding the motor coil.

[0026] The groove width of the groove 3 is 1.5 mm to 2.5 mm, and the groove depth of the groove 3 is 0.5 mm to 1.5 mm. The groove width of the groove 3 is larger than the outer diameter of the wire end 2. The copper wire can be completely placed in the groove 3. The groove 3 provides enough space to avoid excessive stretching or compression of the copper wire, reduces the mechanical damage of the copper wire, protects the integrity of the copper wire, and can better fix the copper wire, reducing the movement and vibration of the copper wire during use, thereby enhancing the stability and reliability of the motor.

[0027] During the automatic winding process, first place one end of the copper wire in the groove 3, which can effectively avoid the friction between the copper wire and the winding coil and the wear caused by excessive friction between the winding coil and the copper wire, and then winding can be carried out.
