Quality Assurance & Testing Protocol

At WGT China Weigao Motor, every motor undergoes a rigorous multi-stage inspection process. Each unit is delivered with a Certified Test Report.

• Routine Tests: DC resistance, insulation resistance, high-voltage withstand, no-load parameters, and vibration/noise analysis.
• Type Tests: Full-load efficiency, power factor, temperature rise (stator/bearing), and overload capability verification.
• Process Control: From raw material physical/chemical testing (coils, iron cores) to dynamic rotor balancing, every stage is audited for precision.

Painting, Packaging & Warranty

• Surface Treatment: Standard 120μm coating (40μm primer + 80μm finish). Custom colors available.
• Export Packaging: Seaworthy, fumigated wooden cases designed for safe long-distance international shipping.
• Warranty: 12 months from commissioning or 18 months from delivery (whichever comes first). Extended warranty options are available upon request.
