Product overview
The YAHREE JT5220-A KV220 is a propulsion motor for fixed-wing UAV integration. Its body measures 60 ±0.10 mm in diameter and 46 ±0.5 mm in length, weighs 432 ±15 g and uses a 24N28P slot/pole arrangement. This version has a speed constant of 220 RPM/V ±5%. Integration recommendations cover a 6S–12S LiPo battery, a 6S–12S/130 A ESC and an 18–20 inch propeller. OEM/ODM customization options include KV, appearance and color.
At 44.4 V, maximum continuous current and power are 66 A and 2930 W, with a motor temperature of 94°C at maximum continuous current. The higher rating of 90 A and 3996 W at 44.4 V is limited to 15 seconds. Maximum magnet operating temperature is 150°C, with a recommended maximum of 120°C. With the 1910 propeller, 30% throttle at 43.5 V yields 3030 g thrust and 6.16 g/W efficiency; 100% throttle at 43.1 V yields 10370 g and 3.73 g/W. Thrust varies with propeller, voltage and test conditions.
