The development of the motor maintenance digital production line addresses pain points in traditional motor maintenance models. By incorporating automation and information technology, it improves assembly efficiency (by over 20%) and quality while reducing maintenance costs. It enables full traceability of maintenance work orders and material requisitions, including quality cross-checks, repair data confirmation, and progress control, gradually enhancing motor maintenance quality traceabili-ty. It also achieves automated data collection and information-based quality management, enabling paperless operations and forming a digital maintenance system.
