Product overview
The YAHREE 2807 is a brushless propulsion component for long-range FPV, cinematic and mapping drones. Its 1300 RPM/V configuration uses a 12N14P slot-and-pole arrangement within a body measuring 33.4+/-0.15 mm in diameter and 34.5+/-0.5 mm long. At 57+/-2 g, it provides a defined motor envelope for propulsion integration. Recommended supporting equipment comprises a 4-6S LiPo battery, a 6S/80A ESC and a 6–7-inch propeller. OEM/ODM projects can specify custom KV, appearance and color.
Electrical integration must distinguish continuous operation from short bursts: the motor is rated at 20 A and 504 W continuously at 25.2 V, while 52 A and 1310 W are limited to five seconds. Temperature at maximum continuous current is 90°C; the magnet has a 150°C operating maximum with 120°C recommended. Propeller selection also changes the operating point. At 25.2 V, the HQ7*4.5*3 three-blade configuration reaches a listed 2720 g thrust at 55.4 A and 1396.08 W, exceeding the separate maximum current and power ratings.
