Product overview
The YAHREE DF 4114 Multi-Rotor Motor KV430 is a brushless propulsion component for medium and large multirotor drones, including aircraft used for aerial photography, mapping, inspection and logistics. Its construction combines a 20SW1500 core, N38SH heat-resistant magnet, SUS420J2 shaft, high-precision bearing and 18AWG silicone wire. The 12N14P motor measures 48+/-0.1 mm in diameter and 31+/-0.5 mm long, providing dimensions for installation planning. The KV430 version recommends a 4-6S LiPo supply, 6S/80 A ESC and 16-inch propeller. Custom KV, appearance and color options support OEM/ODM projects.
With a 16-inch propeller at 24 V and 100% throttle, the motor produces 4420 g thrust while drawing 42.9 A and 1029.6 W, with efficiency of 4.29 g/W. Thrust varies with propeller, voltage and test conditions. At 24 V, the continuous current/power limit is 46 A/1104 W, while 51 A/1224 W is limited to a maximum of 15 seconds. Temperature at maximum continuous current is 80°C. The magnet has a maximum operating temperature of 150°C, with a recommended maximum of 120°C.
