Product overview
The T-MOTOR AX435-A is a brushless motor for fixed-wing cruise UAV propulsion, available in KV220 and KV250 versions. Designed for pusher configurations, it provides rear shaft output for internal mounting and front shaft output for external mounting. An integrated collet-type hub accommodates folding propellers. The motor measures 49.5 mm in diameter by 77.5 mm and has a 150 mm enameled-wire lead. Both versions use a 12N14P configuration, are rated for a 12S LiPo supply and weigh 480 g including cable.
The KV220 version has specified maximum power of 1550 W, peak current of 75 A and maximum thrust of 7.5 kg; the KV250 version has corresponding specifications of 2000 W, 82 A and 9.7 kg. Thrust depends on the propeller and operating point. T-MOTOR recommends an aircraft takeoff weight of 10–12 kg and a setup pairing the AX435-A with an AT115A ESC and an AUFZ16*13, AUFZ17*14 or AUFZ17*11 propeller. This takeoff-weight recommendation applies to the aircraft configuration.
