U-Power Technologies’ U7 motor features stable, durable, and powerful performance, designed for multi-copters with an all-up weight (AUW) of 10-24kg, and comes with waterproof capabilities.

The U7 motor boasts six holes that are beveled upwards, featuring waterproof and sand-resistant design. Notably, this motor cools down an impressive 2.5 times faster than comparable products. Additionally, its ABNORMAL SHAFT features a specialized screw for secure installation of the stator and rotor.

Equipped with EZO bearings, this motor ensures a prolonged service life of over 1,600 hours with trouble-free operation, allowing for smoother performance, reduced noise, and extended runtime.

The high-standard precision winding uses a thin 0.2mm silicon steel sheet, ensuring tight coils and slots, which reduces heat and eddy currents, ultimately improving the motor’s efficiency.

Recommended Specification: Maximum Efficiency – 9.6 grams per watt. Maximum Thrust – 2 kilograms per arm. Operating Voltage – 24 volts. Recommended Propeller Size: T-MOTOR CF20*6.
