Product overview
The YRDRONE YU13819 KV39 is a motor for multirotor propulsion integration. Its body measures 147.5+/-0.1 mm in diameter and 50+/-0.3 mm in length, with a weight of 1795+/-18 g. The KV39 configuration has a speed constant of 39+/-5% RPM/V. Recommended supporting components are a 14-24S LiPo supply, a 14-24S / 200 A ESC and a 49-inch folding propeller. OEM/ODM projects can specify custom KV, appearance and color.
At 100 V, maximum continuous current and power are 120 A and 12000 W, with a temperature of 93°C at maximum continuous current. The higher 180 A / 18000 W rating applies for a maximum of 15 seconds. Magnet operating temperature is limited to 180°C, with 150°C recommended as the maximum. With the 49-inch folding propeller, the 100% throttle entry gives 47012 g thrust at 99.81 V and 84.5 A. Thrust varies with propeller, voltage and test conditions.
