The TMotor UAV Brushless Motor U8II KV85 offers a centrifugal air-cooling system and a built-in array for efficient heat dissipation. The terrific cooling performance guarantees reliability during running. It can operate in a 50 °C environment disdainfully.

U8LITE and U8M are with the same magnetic circuit design, Imported German 7075 aviation aluminum alloy assists in motor toughness while the motor cap is simplified with 15%+ weight reduction. An open structure offers a better cooling performance.

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: The curved magnets in the new U8 have less magnet space. Optimized design help save energy during flight.

Heavy Load: with the fall of motor temperature, the max thrust of the new U8 reaches 7.3 kg from 5 kg doubling the aircraft payload.

Imported Custom Bearings Dual Bearing Protection: Simulated analyses are carried out based on the stress under the operating condition in axial and radial directions. Redesign of custom bearing contributes to prolonging 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 avoids soldering. Say no to faulty and cold soldering. Imported German 7075 aviation aluminum alloy reinforces the motor structure by 20%.

Sliver leads the trend with intelligence: FOC ESC: Smooth control, Low noise, High efficiency. The latest ultra-light 28-inch carbon fiber prop weighs only 55g (the weight of a standard 28-inch CF prop is 98g). An increase of 12% in-flight time and weight loss of 320g (quadcopter) is attainable once U8LITE and the ultra-light prop are on your aircraft.
