The PL7Q-220A Stator Wire production line is designed for the stator production of alternators in gasoline-powered vehicles. Its main processes include winding, pre-compression, coil twisting, taper forming, connection forming, stacking, layering, compaction, paper application, bending, welding, wire tying, winding & roundness correction, preliminary testing, varnishing, inner circle honing, dimensional inspection, final testing, painting, and marking. The copper wire is first wound and then, after a series of shaping processes, embedded into the slots of the iron core; insulation paper is inserted into the slots of the flat iron core, which is then bent into a circle using a bending and welding machine; in the final stage, the stator undergoes dimensional shaping, varnishing, marking, and other operations. The production cycle is ≤24 seconds.
