Multi-rotor UAV Efficient Motor U8

Multi-rotor UAV Efficient Type Motor U8 
First generation of efficiency motor for application of surveillance that requires long flight time of over 2 hours

U8 Efficiecy Type: 20-120 mins high-end aerial photography / exploration / archaeology / remote sensing surveying and mapping etc
Industrial grade


Patented Technology, Innovative Locking Method
No circlip required, easily secure the motor's shaft with two screws


Light Weight Hollow Design with Better Heat Dissipation
The unique hollow design allows heat to dissipate effectively, prolonging the life of the motor and reducing the overall weight.



Larger bearings lower noise
Larger bearings are suitable for disc type motor that operate at a lower RPM, help reduce applied stresses, vibration and noise.
The larger bearings satisfy the needs for a smoother, quieter and steadier flight.
The efficiency reaches 18g/w (2 times that of comparable motors) at 50% throttle.



Precision Windings High Standard Silicon Steel Sheet
The precision winding techniques assure a tighter fit between each coil and slot, reducing copper losses. In addition, an advanced 0.2mm size silicon steel sheet aids in reducing heat and eddy currents further optimising efficiency.
