Burr Inspection for Stator Cores
Burr inspection controls stamping burr height and edge quality to ensure accurate lamination assembly, minimize air-gap variation, and support reliable motor core performance.
Precise burr control is essential for maintaining the dimensional accuracy and assembly quality of stator laminations. By controlling burr height and edge condition during stamping, we help reduce lamination interference, prevent insulation damage, improve stacking consistency, and support reliable magnetic and mechanical performance in finished stator cores.
