At present, domestic motor manufacturers are basically embedding wires manually, and some small or micro motors are offline mechanically. Due to the limitation of tooling and technology, large and medium-sized motors can only be offline manually. We do maintenance. When some foreign motors are repairing imported motors, due to the high labor cost, they may have to use mechanical off-line instead of labor. China is crowded and cheap, so it won't use mechanical methods. Because the equipment cost is higher, it is not as good as the labor cost.
