The BrotherHobby SE 3115 900KV brushless motor is built for high-torque applications, making it an excellent choice for long-range FPV drones, cinematic platforms, and heavy-lift multirotors. Featuring a large 31×15 mm stator and a 900KV rating, this motor delivers strong, efficient thrust while maintaining smooth and stable flight characteristics.
Optimized for 6S and 8S power systems, the SE 3115 performs best with 9–11 inch propellers, providing excellent efficiency for extended flight times and reliable lift for payload-carrying setups. Its smooth throttle response and low vibration profile make it especially suitable for cinematic FPV, aerial imaging, and mapping missions where flight stability is critical.
The motor bell is manufactured from durable aluminum alloy, offering effective heat dissipation and structural strength during sustained high-load operation. Internally, quality stator materials and optimized winding techniques reduce electrical losses, improve efficiency, and help maintain cooler operating temperatures over long flights.
A reinforced steel shaft combined with high-quality bearings ensures smooth rotation, low mechanical noise, and long service life, even under demanding flight conditions. Each motor is factory-balanced to deliver reliable, vibration-free performance right out of the box.
