Product overview
The YAHREE 2812 is a brushless propulsion motor for cinematic and cruising FPV drones, including long-range builds and cinematic lifters. Its construction combines hard-anodized aerospace-grade 7075 aluminum with imported NMB bearings and a 12N14P slot/pole arrangement. The motor measures 33.4+/-0.15 mm in diameter and 40+/-0.3 mm in length. Ultra-thin stainless steel dust filters sit in the stator, while split exhaust blades form part of the rotor’s heat-management arrangement. It is a motor component for integration into a drone propulsion system.
The 930 KV and 1100 KV versions weigh 76.5+/-2 g and 78.5+/-2 g respectively. Both recommend 4-6S LiPo power and a 6S/100A ESC; their respective propeller recommendations are 7–9 inches and 7–8 inches. At 25 V, both have a 33 A/825 W continuous rating, with higher maximum ratings limited to 10 seconds. Maximum magnet temperature is 150°C, with 120°C recommended. Bearing replacement is recommended after 60–80 flight hours, even if bearings appear in good condition. For best performance, recommended takeoff weight is up to 3600 g, depending on setup.
