Product overview
The T-MOTOR AX435-B is a brushless propulsion motor for fixed-wing cruise UAVs, with a recommended takeoff-weight range of 10–12 kg. Its pusher-oriented architecture supports rear shaft output for installations inside the airframe and front shaft output for external mounting. The motor measures Φ49.5 × 89 mm, has 8 mm shaft diameters at both ends, and weighs 485 g including its cable. An integrated collet-type propeller hub accommodates folding propellers, while tilted centrifugal fins in the end caps provide cooling aligned with the direction of rotation.
The motor is offered in KV220 and KV250 configurations, both rated for a 12S lithium-polymer battery. KV220 specifies 1550 W maximum power, 75 A peak current and 7.5 kg maximum thrust; KV250 specifies 2000 W, 82 A and 9.7 kg respectively. The recommended propulsion combination pairs the AX435-B with an AT115A ESC and an AUFZ16×13, AUFZ17×14 or AUFZ17×11 propeller. These are recommended integration components. The motor's 150 mm enameled-wire leads, 12N14P configuration and collet hub define its principal electrical and mechanical integration features.
