15mm Sensorless Brushless DC Motor

Imported Custom Silver Wires
Fast current flow on silver wires surface improves motor response speed for easy control over aircraft. Silver winding greatly reduces copper loss and helps lower motor heat by 30%.

Magnetic Circuit Optimization
Curved magnets in U8 are with less magnet space. Optimized design help save energy during flight.

Max. Thrust: 7.3kg Heavy Load
With the fall of motor temperature, the max thrust of new U8 reaches 7.3kg from 5kg which doubles the aircraft payload.

Patent Technology
Protect motors from sand, dust, foreign matters and magnetic particles. Bore Diameter of net < 1 mm

Sillicon Steel Sheet
Special anti-rust treatment Capability of passing 48h salt spray test.

Imported Custom Bearings, Dual Bearing Protection
Simulated analyses are carried out based on the stress under operating condition in axial and radial directions. Redesign of custom bearing contributes to prolong the bearing life to 1000h+ under normal operation. Property of anti-rust and anti-corrosion from dual bearing protection gets the motor through 6h salt spray test.

Safety
The silver wire lead avoid soldering. Say no to faulty and cold soldering. Imported German 7075 aviation aluminum alloy reinforces the motor structure by 20%.
