  • Premium Materials, Durable & Reliable: Stator and rotor use high-purity enameled windings with Class F insulation resistant to high temperatures, preventing overheating damage during frequent start-stop cycles. High-wear-resistant graphite brushes ensure stable conductivity and extend service life. Premium aluminum alloy die-cast housing provides vibration resistance, impact protection, and dust/splash resistance, suitable for various driving conditions. Built-in high-quality one-way clutch automatically disengages after engine start, preventing flywheel back-drive damage to starter.
