Flatness Inspection for Stator Cores
Flatness inspection verifies lamination and core flatness to prevent deformation, ensure proper assembly, maintain stack stability, and support consistent motor performance.
Maintaining precise stator core flatness is essential for accurate assembly, stable stacking, and reliable motor performance. Our flatness inspection identifies deformation, warping, and uneven surfaces throughout production, ensuring the finished core meets specified flatness requirements and maintains consistent geometry during motor assembly and operation.
