Product overview

The T-MOTOR U7 V2.0 is a multirotor brushless DC motor designed for high-thrust UAVs in the 10-24kg class, serving aerial imaging, photography, delivery services and agricultural crop protection. Its KV280, KV420 and KV490 variants support 3-8S lithium batteries and use a 12N14P slot and pole configuration. Each motor measures Φ60.7×39.5mm, with a 6mm shaft and 750mm wires in size 16#. Maximum current ratings are 35A, 40A and 44A respectively, with corresponding maximum continuous power ratings of 204W, 350W and 500W.

Side openings accelerate airflow to improve heat dissipation efficiency by a factor of 2.5. Precision windings combine imported oxygen-free copper wire rated for 180°C heat resistance with 0.2mm imported silicon steel laminations, helping reduce heat generation and eddy currents while maintaining slot fill. Large imported bearings support smoother, quieter running, with fault-free operating time under load reaching up to 1600 hours. Including wires, the KV280, KV420 and KV490 variants weigh 317g, 296g and 299g respectively.
