As a premier coreless motor manufacturer, we provide high-performance, ultra-reliable 8520 Coreless Brushed Motors paired with 65mm propeller solutions. Engineered specifically for 1S battery power systems, this series delivers extreme RPM and instant response within an ultra-lightweight frame—making it the ideal propulsion source for drones, RC aviation, and micro-smart hardware.
🛠️ Factory Direct & Full Customization Services
- Comprehensive Parameter Tailoring: As a direct source factory, we customize shaft length, shaft diameter, lead wire length, terminal connectors, rated voltage, speed, and torque performance to seamlessly match your specific project requirements.
- Extreme High-Speed Precision: Operating at a standard rated 3.4V to clock 51,000 RPM, and capable of pushing up to 56,000 RPM at 3.7V, ensuring rapid and crisp responsiveness for your devices.
- Ultra-Lightweight Engineering: Weighing just 5 grams per unit, it minimizes overall payload to significantly maximize flight times and structural agility.
- Low Resistance & Quiet Operation: Utilizing high-grade magnets and an advanced ironless winding structure, our motors minimize internal friction and electrical resistance, ensuring high efficiency with minimal noise.
