Product overview
The T-MOTOR AT2820 is a long-shaft propulsion motor for 3D, F3A and UAV fixed-wing aircraft with a flying weight of 1.4-1.6kg. Its KV880, KV1050 and KV1250 versions share a Φ35.2*63.5mm motor body, 12N14P configuration and 100mm enameled-wire leads. Each has 5mm shaft diameters at both the input and output. Weight including cable is 139g for KV880 and KV1050, and 141g for KV1250. Internal resistance differs across the three versions: 39mΩ, 28mΩ and 16mΩ, respectively.
The supplied configuration consists of one AT2820 motor and one hardware pack. Recommended accompanying components are the T-MOTOR AT55A or AT75A ESC and T12*6 or T13*6.5 propeller. All three motor versions support 3-4S LiPo batteries. Their maximum power ratings are 700W, 900W and 1000W for KV880, KV1050 and KV1250 respectively, each qualified for 180 seconds; peak current ratings for that duration are 45A, 65A and 70A. The motor family has a maximum thrust specification of 3.1kg.
