CGF INSPECTION Pre-shipment inspection for Electromotor
CGF provides professional Pre-Shipment Inspection (PSI) service for industrial electromotors before shipment. Our qualified inspectors implement on-site random sampling inspection in factory based on international AQL standards. We identify potential mechanical & electrical defects at the final production stage, effectively reduce failure risk after delivery and avoid costly overseas returns. Main checkpoints for electromotor pre-shipment inspection:
• Verify overall dimension, shaft size, mounting type and model specification against approved technical drawing.
• Inspect housing coating: scratch, paint peeling, rust, deformation, casting defect and oil leakage.
• Check nameplate data, voltage, power, IP protection grade, marking clarity and compliance label.
• Inspect terminal box, wiring terminal, cable interface, sealing condition and connector tightness.
• Carry out no-load running test, check abnormal noise, vibration, temperature rise and rotation smoothness.
• Test insulation resistance, grounding continuity and safety protection structure.
• Audit anti-rust treatment, plastic wrapping, wooden crate reinforcement, shipping mark and export packaging.
CGF Pre-Shipment Inspection for Electromotor
Complete Electromotor Inspection Checklist
✅ Specification & Dimension Verification
Measure overall size, shaft diameter, shaft extension length, mounting hole position and flange size. Confirm motor model, power, speed match your technical requirements and approved sample.
✅ Casing & Surface Appearance Inspection
Check motor housing for paint damage, scratches, rust spots, casting pores, cracks and deformation. Inspect oil seal end cover for traces of oil leakage.
✅ Nameplate & Marking Audit
Verify nameplate parameters including power, voltage, frequency, IP rating, insulation class and serial number. Check warning labels, rotation mark and certification logos are complete and legible.
✅ Terminal Box & Internal Wiring Check
Inspect terminal block tightness, cable entry sealing, wire arrangement, grounding connection. Prevent loose wiring, poor sealing leading to water or dust ingress.
✅ No-Load Operation Performance Test
Switch on power for running test. Monitor abnormal friction noise, excessive vibration, overheating and irregular rotation speed.
✅ Electrical Safety Test
Complete insulation resistance test and continuity of protective earth circuit to meet standard safety requirements.
✅ Anti-Rust Treatment & Export Packaging Check
Inspect anti-rust oil on shaft, plastic protective covers, moisture-proof desiccant inside crate. Check wooden box strength, shockproof filler and correct shipping marks.
✅ English Inspection Report
After on-site audit, you will receive a full inspection report including dimension data, defect photos, testing records and comprehensive quality conclusion.
