Product overview
The Yahree LJ5330 KV220 is a brushless propulsion motor for fixed-wing UAVs and VTOL aircraft. Its aluminum alloy construction incorporates a 12-slot, 14-pole arrangement with a speed constant of 220+/-5% RPM/V. Motor diameter is 63+/-0.10 mm, motor length is 56+/-0.5 mm, and weight is 400+/-15 g. A long shaft and multiple mounting variations accommodate different frame installations. Cooling uses a bottom air inlet and centrifugal fan structure, while the mounting design includes an embossed interface and reinforced housing.
The motor recommendations specify 12S-14S LiPo batteries and 18-20 inch propellers, alongside a YHR Fixed-Wing 130 A ESC rated for 6S–12S and a specific recommendation for 19-inch fixed-wing propellers. At 44 V, maximum continuous current and power are 70 A and 3080 W; the 95 A and 4180 W maximum is limited to 15 seconds. The magnet temperature limit is 150°C, with 120°C recommended as the maximum. Recommended aircraft takeoff weight is 4500–5000 g depending on actual payload configuration. Thrust varies with propeller, voltage and test conditions.
