Laser cutting technology revolutionizes motor core manufacturing with ±0.01mm precision, replacing the traditional stamping process to achieve mold-free, efficient and low-cost pilot production. The core breakthroughs include: dual-drive gantry system to ensure static accuracy, fiber laser to stabilize the spot and reduce burrs, intelligent pulse process to control thermal damage and achieve high roundness of the microvia, magnetic polishing and visual inspection technology to control the stacking error. The technology has been applied to new energy automobile flat wire motors (slot precision ±0.015mm), medical micro motors (0.05mm line width) and other fields, improving energy efficiency by 2% and reducing R&D costs by 80%. In the future, it will be developed in the direction of AI parameter optimization, picosecond cold processing and cutting inspection integration.
