Description

Technical Field

[0001] This utility model relates to the technical field of flat wire motor welding, and more specifically, it relates to a flat wire motor stator welding device. Background Technology

[0002] With the continuous development of electric vehicles, the power density of electric vehicle motors is also increasing. Compared with round wire motors, flat wire motors have a higher slot fill factor. The increased slot fill factor means that more copper wire can be filled within the same space, generating a stronger magnetic field and further improving power density. Winding welding is a crucial process in the trial production of flat wire motors. Because welding requires clamping the two copper wires together, traditional manual clamping can result in tiny gaps between the wires, leading to defects such as bubbles and incomplete welds, affecting stator quality. Furthermore, the large number of weld points makes manual welding inefficient and labor-intensive. Utility Model Content
