Product overview

The T-MOTOR MN3520 KV400 is a motor for aerial photography UAVs, built with EZO bearings and flexible mounting holes. Its 12N14P construction incorporates silicon steel laminations measuring 35mm in outer diameter and 20mm in height. The motor measures Φ42.5×42mm and uses a 4mm shaft. Its 16# wires are 600mm long, with motor weight measuring 222g including wires and 194g excluding wires.

The MN3520 KV400 supports 4-8S lithium batteries, with a no-load current of 1.2A and a maximum current of 38A. At 22.2 V with a T-MOTOR 15*5CF propeller, it produces 1540 G of thrust at 65% throttle, drawing 8.8 A and 195.36 W. With a T-MOTOR 16*5.4CF propeller at the same voltage and throttle setting, thrust is 1780 G, current is 10.2 A and power is 226.44 W.
