T-Motor U8II Eciency Type UAV Motor KV190
The T-MOTOR U8II Efficiency series is the gold standard for high-end UAVs that demand extreme endurance. Whether you are flying the KV100 (ideal for 12S setups) or the KV190 (optimized for 6S/12S flexibility), these motors are engineered to stay in the air longer than the competition. By utilizing advanced iron-cobalt alloy magnets and a lightweight design, the U8II series allows your craft to carry more while consuming less. It’s the motor of choice for pilots who believe that “good enough” isn’t an option when your mission is miles away.
Key Features
What sets the U8II apart is its silver winding and curved magnet architecture. The silver winding provides a lightning-fast response time, allowing for the kind of precise speed control usually reserved for smaller racing drones. Meanwhile, the patented curved magnets optimize the magnetic circuit, resulting in a 15% boost in efficiency. To keep you flying in less-than-perfect weather, the motor is IP45 rated, meaning it shrugs off dust and rain like a local in a drizzle. Additionally, the improved temperature management ensures that even during a 40-minute flight, the motor stays cool and collected.
Specifications
Built for the long haul, this motor boasts an impressive MTBF of approximately 1,000 hours and a service life of up to 1,500 flights. With a maximum thrust of 7.3kg, it effectively doubles the payload capacity of many standard industrial platforms.
Weight: ~272g (KV100) to 277g (KV190)
Protection: IP45 (Dustproof and Waterproof)
Response: Silver wire leads for ultra-fast throttle transitions
Lifespan: Designed for 40-minute duty cycles
Matching Guide: Best paired with T-MOTOR G28*9.2 Props and ALPHA 60A ESCs
Applications
The “U Efficiency” line is purpose-built for industries where reliability is non-negotiable. It excels in long-range surveillance and mapping/surveying, where every percentage of battery saved equals more data collected. Security and protection teams rely on its low-noise profile to operate discreetly. From agricultural spraying to high-altitude cruising, the U8II provides a stable, efficient, and surprisingly quiet power plant. If your job involves “all-weather” flight and “maximum endurance,” you’ve found your motor.
