EMAX ECO II 3115 Brushless Motor 500KV
by EMAX

The EMAX ECO II 3115 500KV motor is engineered for endurance, stability, and powerful performance in cinematic or long-range drone builds. With a robust 3115 stator and 500KV winding, it thrives on 8–10S LiPo systems using 10″ propellers, delivering around 2,000 W of efficient power. Featuring precision dual NSK bearings, a CNC-machined aluminum bell, high-temp multi-strand copper windings, and optimized cooling—this motor offers reliable continuous thrust with low internal resistance (~0.095 Ω) and smooth throttle control (idle current ~0.8 A). Lightweight and durable, it is ideal for heavy-lift, cine, and endurance missions.
