Manufacturing Capabilities

 

Multi-axis CNC machinery maintains uniform copper wire tension and precise turn counts across 6, 8, or 11 poles to eliminate voltage drops.


Monthly output of 80,000 stator units across three dedicated assembly lines to secure your seasonal peak-demand supply chain.


In-house progressive stamping dies maintain silicon steel core structural dimensions within ±0.05 mm to minimize magnetic loss.

 

Quality Control & Testing Standards

 

100% Dielectric & Surge Testing: Every unit undergoes automated insulation validation and a 1,500V high-voltage surge test, with QA inspection logs archived for 3 years.

 

Precision Trigger Gap Inspection: Factory QA verifies pickup trigger gaps using mechanical fixtures to guarantee stable ignition timing and prevent engine stalling.

 

Thermal Shock Validation: Randomly sampled batch units undergo 100 cycles of destructive thermal testing (-30°C to 150°C).

 

ASTM B117 Corrosion Resistance: Salt spray testing validates all exposed steel brackets and terminal pins.

 

Supply Capacity

 

Standard 25-day lead time from deposit to port delivery for full container loads (FCL), backed by a 98.5% on-time delivery record.

 

MOQ is 500 units per specific stator configuration.

 

Anti-static bubble bags are packed inside double-wall corrugated cartons, secured on ISPM 15 heat-treated, fumigation-free wooden pallets.

 

Supports FOB Ningbo/Shanghai, CIF Rotterdam, and DDP destination warehouse routing.

 

After-sales Support

 

24-Month Factory Warranty: Full replacement coverage for electrical failures and material defects under standard operating conditions.


Defective components credited directly against the next invoice based on photo/video evidence, with no return shipping costs required.


Detailed 8D problem-solving engineering reports are provided within 48 hours for any batch-level field issues.

FAQ

 

Q: How long does the GY6 magneto stator typically last?

A: Under normal riding conditions, the stator is designed for 8–10 years or approximately 30,000–50,000 km of service. Actual lifespan depends on engine temperature, electrical load, and maintenance.

Q: What charging voltage does the stator produce during engine operation?

A: The stator delivers 13.5–14.5V charging voltage at normal operating RPM when paired with a compatible regulator/rectifier.

Q: How can I confirm compatibility before placing a bulk order?

A: Compatibility is verified by comparing the engine model, pole count, bolt spacing, connector type, pickup coil position, and flywheel dimensions. Technical drawings or sample parts are recommended before production.

Q: What information is required for OEM customization?

A: Providing the original sample, CAD drawing, engine model, connector specification, wire length, and target output requirements is usually sufficient.

Q: Can the stator be stored for long periods before installation?

A: Yes. When kept in its original moisture-resistant packaging at 5°C–35°C with humidity below 75%, the stator can be stored for up to 24 months without affecting electrical performance.

Q: Is the stator suitable for high-RPM or modified engines?

A: Yes. The silicon steel core and high-temperature insulated copper windings are designed for continuous operation at up to 9,000 RPM, making the stator suitable for most performance-oriented GY6 engines.
