Product overview
The YAHREE 3115 is a brushless motor intended for cinematic and exploration FPV flights. Its 12N14P slot-and-pole architecture accompanies a 900 RPM/V rating with a tolerance of +/-10%. The motor measures 37.1+/-0.15 mm in diameter and 47.8+/-0.3 mm in length, and weighs 120+/-3 g. Recommended propulsion components are an 8–10-inch propeller, a 4–6S LiPo battery and a 6S/120A ESC. OEM/ODM options include custom KV, appearance and color.
The 900KV version has maximum continuous ratings of 50 A and 1250 W at 25.2 V, with a temperature of 105°C at maximum continuous current. The higher rating of 72 A and 1800 W at 25.2 V is limited to 10 seconds. Maximum magnet operating temperature is 150°C, with a recommended maximum of 120°C. Free-load current is 2.8 A maximum at 20 V, and phase-to-phase resistance is 36.5 mΩ +/-8% at 25°C. Thrust varies with propeller, voltage and test conditions.
