U3 KV700 12N14P external rotating brushless motor
With 4mm shaft, 80W drone motor, suitable for 3-4S multi-rotor drone
The U3 multi-rotor brushless DC motor is specially designed for 3-8 kg high-thrust UAVs and is widely used in aerial photography, distribution services, agricultural plant protection and other fields. Its unique side hole design accelerates airflow and increases motor heat dissipation efficiency by 2.5 times. It uses imported oxygen-free copper wire for precision winding, with a temperature resistance of up to 180°C, excellent short-circuit tolerance, and is matched with high-quality 0.2 mm imported silicon steel sheets. This ensures high tank occupancy, reduces motor heating and eddy current losses, and increases efficiency to the last every cent. The motor is equipped with high-quality imported large bearings for smoother operation, lower noise, and a rated load MTBF (Mean Time Between Failures) of up to 1,600 working hours.
