At EMAX, our engineers are constantly innovating to create the ultimate brushless motors. Their latest achievement is the ECO II Series, a new line that enhances performance and durability while maintaining affordability. Completely redesigned, the ECO II features a fresh architecture with a rounded shape and reinforced structure for maximum durability. Its reflective finish adds a sleek, modern touch, blending aesthetics with resilience.
To further elevate performance, the ECO II utilizes N52SH arc magnets instead of the previous N48 magnets, resulting in more powerful throttle response and higher RPMs. This boost in torque and thrust gives pilots the flexibility to tackle any racetrack or flight scenario with ease. The ECO II Series represents a significant advancement in affordable brushless motor technology, ushering in a new era of performance for all.
The Original Emax ECOII-2004-3000KV Brushless Motor is a versatile drone motor used across a wide range of applications including FPV racing drones, agricultural spray drones, aerial photography platforms, and custom multirotor builds.
Common use cases:
Replacement motor for crashed or worn-out drone
Building a custom quadcopter or hexacopter from scratch
Upgrading to a more efficient motor for longer flight times
This product is ideal for drone builders, FPV pilots, and agricultural drone operators.
Technical Tip: When selecting a drone motor, match the KV rating to your propeller size and battery voltage. Lower KV = larger props + more efficiency; higher KV = smaller props + more speed.
