T-MOTOR P80 III KV100 (ohne Stift, Agrar)

The P80 III KV100 from T-MOTOR, a Chinese maker, is an enclosed, waterproof and corrosion-resistant outrunner for agricultural spraying drones. The layout has 36 slots and 42 poles, and the housing measures 91.6 x 43 mm.

The motor weighs 649 g. At KV 100 and 47.15 V that works out to about 4,700 rpm at no load. Power and peak current, 2,700 W and 60 A, apply for 180 s and fit 45 V. The recommended propeller is the G30x10.5 on 6 to 12S. The product overview quotes up to 18,200 g of thrust without stating the set-up; the test-stand table shows about 14 kg with the G30x10.5 at 47.15 V. As a matching ESC the maker names the FLAME 80A 12S, whose 80 A designation lies a good third above the peak current of 60 A.

Spraying plant protection products from the air is subject in the EU to its own authorisation rules under plant protection law, alongside aviation law. For EU classification the take-off mass of the whole aircraft counts, tank fill included: C3 and C4 reach up to 25 kg, and above that the specific category with an operational authorisation applies. Remote ID is mandatory for C1 to C3. A 12S battery passes the 160 Wh air-transport limit from about 3.6 Ah.

Waterproof and corrosion-resistant does not mean maintenance-free: after work the motor and the cable exit should be rinsed with clean water and dried, because spray residues attack bearings and seals. Check the bearing run, the winding insulation under sustained heat and the bell's concentricity.
