Moters & Appliance Parts Measurement

Motors & Compressors Shafts Measurement

Application Background

In motors and compressors, shaft precision directly impacts the performance, efficiency, and lifespan. Motor shafts require precise control of grinding outer diameter, segment height and runout due to their high-speed design. Compressor crankshafts feature complex geometries that require more advanced measurement, including Roundness, Cylindricity and Coaxiality. However, traditional contact tools and CMMs are slow, labor-intensive, and unsuitable for high-volume inline inspection.

Common Measurement Challenges

• High accuracy requirements are limited by operator variability in manual measurement
• Complex crankshaft geometries are difficult to measure with contact tools
• CMMs are lab-based and cannot provide real-time process feedback
• Manual record-keeping leads to traceability and data analysis issues
• Inline full inspection demands are hard to meet with conventional tools
