Product overview
The T-MOTOR AT2814 is a long-shaft brushless propulsion motor intended for 3D, F3A and UAV fixed-wing aircraft with a flying weight of 1.3-1.4kg. Its KV900, KV1050 and KV1200 versions provide three configurations within the same motor family. Maximum thrust is specified as 2.6kg, while the electrical supply requirement is 3-4S LiPo. The supplied configuration consists of one motor and one hardware pack, making this a propulsion component for integration into an aircraft.
Installation space must accommodate a motor measuring 35.2mm in diameter and 54.5mm in length, together with its 100mm enameled-wire leads. The motor uses a 12N14P configuration and has 5mm input and output shaft diameters. Weight including cable is 108g for KV900, 107g for KV1050 and 108g for KV1200. Recommended matching components are T-MOTOR AT40A or AT55A electronic speed controllers and T12*6 or T13*6.5 propellers; the packing list specifies the motor and hardware pack.
Electrical limits differ by variant and retain explicit time qualifications. KV900 has a 45A peak-current rating and 650W maximum-power rating, KV1050 has 50A and 700W, and KV1200 has 55A and 800W; each of these ratings is specified for 180 seconds. At 10V, idle current increases across the three versions from 1.2A to 1.5A to 1.8A. Internal resistance is respectively 82mΩ, 35mΩ and 26mΩ, so procurement specifications should identify the required KV version alongside its corresponding electrical ratings.
