The coil winding method of the six-slot three-phase stator on the market is mostly one enameled wire around one slot or two slots, which requires multiple wire breaks. After the winding is completed, the wires need to be manually organized, and then the copper wires are spot welded to the corresponding phase terminals, so the production efficiency is not high. When the phase terminals are connected in parallel corners, four copper wires need to be welded to one terminal, which is a great challenge for production processing and connection stability. During the manual operation process, too many wire ends also increase the risk of wiring errors, resulting in low product yield. Summary of the invention
