Product overview
The Kpower DF3115 is a brushless DC propulsion motor designed for 10-inch FPV drones used in racing, freestyle and aerial photography. Its construction combines 0.2mm silicon steel laminations to reduce eddy current losses and core heating, N45H high-temperature magnets and magnet wire rated to 200 °C. Imported NMB heavy-duty bearings are designed for over 1,000 hours of service life. The motor also has a 12N14P slot/pole configuration, rotor balance of ≤5mg and an IP42 rating.
Mechanical integration dimensions are Ф37.5X46.1 mm (Φ1.48" × 1.81"), with a weight of 116 g including cable. Interfaces comprise a 5 mm shaft, M5 propeller mounting holes and 18AWG*300 mm wire. The 900 KV motor operates over 4-6 S, with a recommended 4-6S 80A ESC and 13/15 inch propeller. Rated power is 279 W, maximum power is 1390 W and maximum thrust is 3860 g; no-load current is 1.5 A at 10V.
