The winding line is completed on a single machine. The equipment is advanced in design. All tooling is designed in the form of quick-change. The change of the same punch is completed instantly, and the change of tooling between different punches is less than ten minutes. The whole machine is constructed from world-brand components. The performance is excellent and the failure rate is low. Since there is no need for manual wire transmission, the neatness of the winding is guaranteed when offline, and there is no paint film damage and indentation after offline. The slot full rate can reach more than 90%, which is very suitable for the production of high-efficiency small-notch motor stators.
