Product overview

The T-MOTOR MN4112 UAV motor serves multi-rotor, VTOL and fixed-wing applications, including aerial photography. Available in KV320 and KV420 versions, it is rated for a 6S LiPo battery. The KV320 version has an idle current of 1.1A at 10V, a peak current of 40A for 180s and maximum power of 910W for 180s. The KV420 version has an idle current of 1.4A at 10V, a peak current of 54A for 180s and maximum power of 1210W for 180s.

The motor measures Φ47.4*38.7mm and weighs 172g including its cable. Its 12N14P construction combines an imported silicon steel stator with anti-rust treatment and 180℃ heat-resistant coatings, N45SH magnets and 686ZZ/696ZZ bearings. Level C copper wire has 220℃ heat resistance. Centrifugal cooling and airflow channels provide heat dissipation, with the airflow channel design increasing heat flux by 18%. The lead cable measures 16AWG*150mm, the coil insulation test is 500V for 5s, and package weight is 275g.
