Product overview
The T-MOTOR MN501-S IP45 Multirotor Fixed Wing UAV Motor KV300 belongs to the Navigator motor range and serves propulsion applications in multirotor, VTOL and fixed-wing aircraft. Intended uses include aerial photography, cargo drones, tethered aircraft, mapping and inspection. Its architecture combines a bell-shaped canopy for dust protection and cooling, a centrifugal cooling design and a 24N28P configuration. The motor measures Φ55.6*33.9mm and weighs 170g including cable. Mechanical integration details include 6mm internal and 4mm external shaft diameters, a 16AWG*150mm lead cable, and a mounting limit of ≤5mm for thread penetration into the motor.
The KV300 configuration accepts 6-8S LiPo power and has an idle current of 1.1A at 15V. Its 40A peak-current and 1000W maximum-power ratings each carry a 180s qualification. Recommended propellers measure 20-22 inches; the matching guide names the T-MOTOR P20*6 propeller, Flame 60A 12s v2 ESC and ALPHA 40A 6S ESC, while the electrical specification recommends AIR 40A. Supply consists of one selected-KV motor and one hardware pack, with a package weight of 350g. The motor has IP45 protection, a maximum thrust of 5.2kg and an MTBF of about 1000 hours. Regular lubrication is advised.
