Product overview
The T-MOTOR MN1118 serves as a propulsion component for industrial multirotor UAVs. Its architecture uses a 36-slot, 40-pole arrangement, imported 6902ZZ bearings and a 12 mm output shaft. The published diameter of 120.5 mm and height of 50.9 mm establish an initial installation envelope, while the 150 mm enameled-wire leads inform electrical routing. Procurement therefore concerns a motor for aircraft integration.
The published configurations are KV90 for 14S LiPo and KV108 for 12S LiPo, with different current, resistance, power and weight specifications. Both receive an M200A14S ESC and VZ40x16.1 propeller recommendation. Selection should retain the 180-second qualification attached to maximum continuous power and the manufacturer's qualification of its platform test data as selection references. IP45 protection, winding insulation and magnet temperature ratings describe particular motor properties.
