Product overview
The YAHREE 2208B is a brushless propulsion motor for racing and freestyle FPV drone builds. Its 2550 RPM/V configuration has a +/-5% tolerance and a 12N14P slot/pole arrangement. The motor measures 26.8+/-0.1 mm in diameter and 31.7+/-0.3 mm in length, with a weight of 37+/-2 g. Supplied wiring consists of 155 mm long 20AWG black ultra-soft silicone wire. Its stated application covers 3.5–5-inch propellers, while the specific integration recommendations are a 5-inch propeller, 4S LiPo battery and 4S/80A ESC.
Electrical and thermal limits distinguish continuous operation from short bursts. At 16.8 V, maximum continuous current and power are 33 A and 554 W, with a temperature of 89°C at maximum continuous current. The higher 55 A / 924 W rating at 16.8 V is limited to five seconds. Maximum magnet operating temperature is 150°C, with a recommended maximum of 120°C. Thrust varies with propeller, voltage and test conditions. OEM/ODM projects have options for custom KV, appearance and color.
