Sunl Roketa Vespa J100 Magneto Stator
Overview
The Sunl Roketa Vespa J100 Magneto Stator is an internal electrical component mounted on the engine crankshaft. It utilizes electromagnetic induction driven by the flywheel to generate alternating current (AC) while the engine runs.

Applications Scenarios
Engineered for 2-stroke 90cc-100cc Minarelli engines on Sunl, Roketa, and retro Vespa J100 clones.
Pre-configured 5-wire setup (3-pin block connector + 2 bullet terminals) for immediate plug-and-play installation without wire splicing.
Fully compatible with standard 12V DC chassis systems, stock regulators, and standard 5-pin CDI ignition modules.
Calibrated to factory OEM flywheel magnetic profiles to preserve stock ignition timing and prevent backfiring.
Custom & OEM Service
Connector Customization: Genuine Molex, Amphenol, or waterproof Deutsch connectors available to match your specific wiring harness blueprints.
Harness Length Adjustments: Flexible wire length customization from 250mm to 600mm.
High-Output Upgrade: Optional modification increases charging capacity to 110W (a 30% increase over OEM standard) to support auxiliary electronics or GPS trackers.
Assembly Line Integration: Heavy-duty fiberglass braided sleeving or split-loom corrugated tubing with custom color coding and laser-etched logos/barcodes.
Prototyping Lead Time: CNC-machined and hand-wound samples delivered within 14 business days from technical blueprint sign-off.
Quality Testing
Surge Testing: 100% inter-turn insulation surge testing executed to detect microscopic wire shorts before final assembly.
Dynamic Spin Verification: Automated dynamometer batch testing up to 10,000 RPM ensures output curve stability under maximum engine stress.
Thermal Shock Resistance: 50-cycle thermal shock testing (-40°C to +150°C) to prevent coil cracking and insulation breakdown in extreme climates.
Corrosion Resistance: Passes 72-hour salt spray test (ASTM B117).
Batch Traceability: Permanent laser-etched production date codes and batch numbers on the core rim for direct component-to-material lot tracking.
Supply Support
12 multi-axis CNC winding machines maintain uniform tension, supporting a monthly capacity of 45,000 units.
Annual rolling contracts up to 100,000 units with quarterly or bi-monthly scheduled releases.
60-day safety stock of silicon steel and Class H copper wire stabilizes unit pricing against raw material market volatility.
Regular re-orders are shipped within 30 days, backed by a contractual 1% per-week late delivery penalty.
