Product overview
The T-MOTOR MN1130 KV45/KV53 is a propulsion motor for heavy-lift multirotor UAVs, with applications including logistics, emergency supply and agricultural spraying. Its silver-and-black body measures Φ120.5*65.9mm and uses a 36N40P configuration, a 12mm output shaft and imported 6902ZZ bearings. Imported silicon steel, anti-rust treatment and heat-resistant stator coatings form part of its construction. The motor has an IP45 protection rating and a stated operating temperature range of -30℃~55℃.
Integration centers on a 24S LiPo propulsion system. The KV45 combination pairs an M200A24S ESC with NS45x17.5 or NS47x18 propellers, while KV53 pairs the same ESC with a VZ40x16.1 propeller; these are recommended combinations, with no stated inclusion of those components. The motor has 150mm enameled-wire leads. Custom cable length, mounting-hole pattern, KV, coating, logo and temperature-sensor options are offered. Maximum-power ratings for both variants and the KV45 peak-current rating carry a 180-second qualification.
