A coil insertion machine typically consists of a mechanical transmission system, a variable frequency speed control system, a PLC (Programmable Logic Controller) integrated control system, a human-machine interface touchscreen, and the core winding mold. The mold comprises several grooved guide teeth and guide bars fixed within these grooves. The guide bars are roughly rectangular in shape with no fixed grooves on their outer surface.
Its working principle involves the drive system controlling the winding head to guide the coil along a specific path into the slot of the motor stator core. To improve winding quality, some advanced models employ high-frequency vibration winding technology. This technology ensures smooth entry of the enameled wire into the slot and effectively reduces the stress on the enameled wire during winding. Simultaneously, the equipment incorporates multiple winding modes, allowing operators to select the appropriate mode based on the wire diameter and material (e.g., copper wire, aluminum wire, copper-clad aluminum wire).
A significant design improvement is the elimination of the paper insertion device found in traditional fully automatic winding machines, along with a simplified mold structure using roughly rectangular guide bars with no fixed grooves on their outer surface. After the improvement, the wiring is done by machine, and then the slot cover paper or bamboo strip is inserted manually. This simplifies the machine structure and reduces the equipment manufacturing cost while maintaining production efficiency and product quality at a similar level.
