Concentricity Inspection for Stator Cores
Concentricity inspection verifies the alignment of critical inner and outer diameters to ensure accurate core geometry, precise motor assembly, and stable operating performance.
Precision concentricity control ensures the inner and outer diameters of stator and rotor cores remain accurately aligned within specified tolerances. By minimizing eccentricity and dimensional variation, it supports precise motor assembly, balanced rotation, reduced vibration and noise, and stable performance in high-performance motor applications.
