Key Features
Grade 180 Copper Windings
99.9% oxygen-free copper with 180°C heavy magnet wire. Built specifically to minimize warranty claims in high-temperature, high-load tropical markets.
50,000-Start Carbon Brushes
Engineered with 65% copper content to maximize electrical conductivity.
Anti-Fade N38H Magnets
Dual permanent neodymium magnets retaining stable magnetic flux up to 120°C, ensuring consistent cranking torque during frequent hot-engine restarts.
Anti-Vibration Zinc End Caps
Reinforced die-cast front caps engineered to withstand engine idling harmonics, preventing mounting bolt loosening and bracket cracking.
Quality Control
100% Automated Load Testing: Every unit undergoes computerized OQC testing for no-load current, loaded speed, and torque output before final packaging.
Durability Trials: Random batch samples undergo continuous start-stop testing under simulated engine resistance to verify long-term fatigue limits.
500V AC Insulation Verification: All motors pass a 1-second high-potential (Hi-Pot) test to guarantee zero electrical leakage to the chassis.
In-House Component Casting: Front and rear brackets cast in-house using standardized aluminum alloys to secure critical dimensions and precise mounting alignment.
Barcode Traceability (<350 PPM): Laser-etched serial numbers link each unit to its specific raw material and manufacturing logs, maintaining an audited factory defect rate below 350 PPM.
Supply Capacity
4,500 Units Daily Output: Dedicated starter motor workshops operating multiple shifts to secure stable inventory and uninterrupted volume supply.
Lead Times: OEM/ODM custom sampling completed within 14 business days; repeat container orders dispatched within 30 calendar days.
After-Sales Support
24-Month Factory Warranty
Backed by a 24-month or 20,000-kilometer operational guarantee calculated from the Bill of Lading (B/L) date.
8D Claim Resolution
Defective items receive direct financial credit or replacements in the next shipment; official 8D corrective action reports are issued within 5 business days.
2% Free Wear Parts
Full container orders include a complimentary 2% wear-and-tear parts kit (carbon brushes and oil seals) to support your local distribution networks.
Compliance
ISO 9001:2015 Certified: Manufactured under a certified quality management system with full process traceability. Certificates available for download.
CE & RoHS Compliant: Fully verified for European market safety and environmental regulations; third-party test reports provided upon request.
REACH & IP67 Rated: 96-hour salt spray resistant housing sealed with fluororubber O-rings. Built with non-hazardous materials to ensure smooth customs clearance globally.
