Performance Curve :

Our inrunner Inrunner Brushless DC Motor feature a rotating internal rotor surrounded by stator windings, delivering high rotational speeds with excellent dynamic balance. Operating at 12V–72V, they offer speeds from 5,000 RPM to 50,000 RPM and power ratings from 10W to 3,000W. Ideal for drones, electric tools (drills, saws, grinders), RC hobbies (cars, boats, aircraft), compressors, pumps, centrifuges, and high-speed automation equipment.

1. High speed capability: Precision-balanced sintered or laminated rotor cores enable stable operation at up to 50,000 RPM with minimal vibration (<0.3 mm/s).
2. Compact power density: High-grade neodymium magnets and concentrated windings deliver exceptional power-to-weight ratios (up to 5 kW/kg) in diameters from 20mm to 65mm.
3. Smooth & efficient: Optimized magnetic circuit design achieves >90% efficiency with low cogging torque and minimal electromagnetic noise (<60dB).
4. Durable construction: Stainless steel or aluminum housing, high-speed ceramic or stainless steel bearings, and Class F (155°C) or Class H (180°C) insulation.
5. Integrated sensors: Available with Hall sensors (120° or 60° spacing) or sensorless configuration for high-temperature or harsh environments.
6. Custom options: Various shaft lengths/diameters, custom winding KV ratings (RPM per volt), front/rear mounting flanges, and IP54–IP65 sealing.
7. Production capacity: 350,000 units/month with 4–6 week lead time for custom windings or shafts.
