Product overview
The T-MOTOR Navigator MN701-S KV280 is a brushless propulsion motor intended for multirotor, VTOL and fixed-wing UAVs. Its civilian application range includes aerial photography, cargo drones, tethered aircraft, mapping and inspection. The KV280 configuration uses a 6S LiPo supply, with recommended propeller diameters of 24–26 inches and recommended ESCs comprising the FLAME 70A 6S and FLAME 100A 6S. Its electrical specifications include an idle current of 2.0A at 17V, a peak current of 65A for 180 seconds and maximum power of 1600W for 180 seconds.
The motor measures 79.2mm in diameter by 37.4mm and weighs 355g including its cable. It combines a 24N28P configuration with centrifugal cooling, imported 608ZZ bearings and IP45 ingress protection. Both the IN and OUT shaft diameters are 8mm, while the lead cable is 14AWG and 150mm long. Internal resistance is 23mΩ. Its Level C copper wire has a temperature-resistance specification of 220°C, and its magnets have a temperature-resistance specification of 150°C; these material ratings do not define the motor's permissible operating temperature.
