CGF Pre-Shipment Inspection for Electromotor
Sourcing large industrial electromotors, three-phase motors, high-voltage motors and driving motors from Chinese manufacturers? CGF Inspection provides reliable Pre-Shipment Inspection (PSI) service for electromotors before goods leave the factory.
Pre-Shipment Inspection will be scheduled when over 80% of bulk production is finished. Our inspectors carry out random sampling according to recognized AQL standards to evaluate overall quality consistency. All non-conformities will be photographed, recorded and notified to the factory for rectification before container loading.
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.
Avoid motor breakdown and customer claims after arrival. Arrange professional pre-shipment inspection for your electromotor orders with CGF Inspection.
