The GNR65 is a high-performance permanent magnet starter motor designed for passenger cars, SUVs, and light commercial vehicles. It features a planetary gear reduction system, which delivers high torque at low speeds while minimizing size and weight—critical for compact engine compartments in modern vehicles. The motor operates on a 12V electrical system with a power output of 1.4kW, making it ideal for starting engines ranging from 1.5L to 3.0L displacement.
With a stator outer diameter of φ65mm, the GNR65 offers a compact and lightweight design weighing only 2.5kg, reducing overall vehicle mass and improving fuel efficiency. The permanent magnet rotor provides higher efficiency and longer lifespan compared to traditional wound-field designs, while the planetary gear set ensures smooth and reliable engagement with the flywheel.
Engineered for extreme environments: operates reliably across a wide temperature range of -40°C to +125°C, ensuring reliable cold starts in Arctic conditions and stable performance in desert heatwaves. The integrated electromagnetic switch includes anti-welding protection, preventing contact point sticking during repeated use. Additionally, the switch incorporates a breathable membrane structure, which prevents ice formation on contacts in cold climates, ensuring consistent operation even in freezing temperatures.
Safety is prioritized through the use of flame-retardant materials throughout the housing and internal components, enhancing fire resistance and meeting global safety standards. The compact structure minimizes space requirements in tight engine bays, while the robust mechanical design resists wear and vibration over time.
The motor is rated for 50,000 start cycles, making it suitable for long-term use in both urban and rural driving conditions. All units undergo rigorous testing, including thermal cycling, vibration endurance, and full-load cranking tests, to ensure consistent performance under real-world conditions.
