TM2812 Brushless Outrunner Motor 900KV & 1100KV 78g for UAV & Industrial Drive
Dual KV Options for Different Mission Profiles —
900KV (25V): Tuned for maximum efficiency and endurance. It produces 1534g thrust at 50% throttle with an outstanding efficiency of 4.14 g/W, peaking at 3066g thrust (1127W) at 100% throttle. Ideal for long-endurance flight.
1100KV (25V): Tuned for aggressive performance and heavy lifting. It delivers 1562g thrust at 50% throttle at 4.00 g/W efficiency, peaking at an impressive 3313g thrust (1644W) at 100% throttle.
High Power & Thrust Density — With a max power of 1122W (900KV) and 1650W (1100KV), the B2812 generates exceptional thrust for its class, easily powering heavy multirotors and large fixed-wing aircraft.
Optimized for 9-Inch Propellers — The 14-pole rotor and 28x12mm stator are specifically calibrated for the HQ9x3.5x3 prop, ensuring precise throttle response and high aerodynamic efficiency without needing a gearbox.
Precision & Durability — Features a robust 5mm titanium alloy shaft with an M5 CW thread, a 4x M3 mounting hole pattern (19x19mm), and a compact 33.9x41.9mm motor size.
Thermal Resilience — Built to handle demanding flight conditions. At 100% throttle for 2 minutes, the internal temperature stabilizes at 96.5°C (900KV) and 108°C (1100KV), ensuring reliable operation under extreme loads.
Ready to Install — Each unit ships with 4x M3x8 screws and 1x M5 nut, making it a drop-in upgrade for your propulsion system.
Heavy-Lift & Long-Endurance UAVs — Perfect for industrial survey, mapping, and agricultural spraying drones requiring 9-inch props and extended flight times. The 900KV variant's 4.14 g/W efficiency is ideal for maximizing battery life.
Cinematic & Heavy-Payload Drones — The 1100KV variant's 3.3kg peak thrust per motor provides the punch needed for large cinema cameras and heavy FPV platforms.
Fixed-Wing & VTOL Aircraft — Excellent for vertical take-off and landing (VTOL) hybrid UAVs and large fixed-wing FPV planes where reliable, high-torque propulsion is critical.
eVTOL & Advanced Air Mobility — Suitable for scale model eVTOL prototypes and experimental personal aerial vehicles requiring reliable multi-rotor propulsion.
High-Performance RC Models — Large-scale RC planes, gliders, and heavy-duty RC cars or boats that require powerful, high-RPM brushless power in a lightweight package.
Industrial & Lab Equipment — High-speed centrifugal test rigs, wind tunnel propulsion fans, and custom industrial blowers where a compact, 1650W outrunner motor is needed.
Robotics & Heavy-Duty Actuators — Direct-drive propulsion for large mobile robots, track drives, and heavy-duty aerial robotics.
