Product Technical Specification: High-Performance Motorcycle Magneto Stator¶

1. Product Overview¶

This series of magneto stators is specifically designed for the motorcycle market, targeting extreme reliability and high power output. By utilizing 220°C (Class HC) ultra-high temperature enameled wire and 100% pure oxygen-free copper materials, it ensures superior power generation efficiency and an exceptionally long service life even under severe high-temperature and high-vibration environments.

2. Key Selling Points¶

🚀 220°C Industrial-Grade Heat Resistance Technology¶

Material Grade: Uses Class HC (220°C) composite-coated enameled wire.
Core Advantage: Far exceeds industry standards (typically 180°C), effectively preventing coil burnout during heat buildup from traffic congestion or prolonged high-RPM engine operation.

💎 100% Pure Oxygen-Free Copper Windings¶

Low Internal Resistance: Compared to aluminum or alloy wire, internal resistance is lower, significantly reducing heat loss (\(I^2R\)).
High Conversion Rate: Improves power generation efficiency by 15% - 20%, ensuring stable battery charging even at idle.

🛡️ Structural Stability and Durability¶

Vibration-Resistant Design: Copper wire possesses superior mechanical tensile strength and ductility, perfectly withstanding the high-frequency vibrations of a motorcycle engine.
Oil and Corrosion Resistant: Specialized varnish film formulation prevents peeling and aging even with prolonged immersion in engine oil.

3. Technical Comparison¶
