Product overview
The T-MOTOR MN1118 KV90/KV108 is a motor for heavy-load multirotor UAVs used in cargo transport, firefighting, emergency delivery, and agricultural or forestry spraying. Its silver-and-black body measures Φ120.5*50.9mm, with a 36N40P slot-and-pole arrangement, a 12mm output shaft, imported 6902ZZ bearings and 150mm enameled-wire leads. The motor has IP45 protection and a stable operating temperature range of -30℃~55℃. The recommended propulsion combinations pair either motor version with an M200A14S ESC and VZ40x16.1 propeller.
The KV90 configuration uses a 14S LiPo supply and weighs 1170g including leads, while KV108 uses 12S and weighs 1186g including leads. Their respective maximum thrust specifications are 39.2kg and 38.0kg; rated thrust per axis is 16~18kg. Maximum continuous power carries a 180s qualification: 2281W for KV90 and 2230W for KV108. Maximum current is 163A and 192A respectively. Both configurations share magnets resistant to 180℃ and a winding insulation withstand-voltage test of 1000V.
