EMAX ECO II 2207 1900KV Brushless Motor

The EMAX ECO II 2207 1900KV is an upgraded brushless motor tailored for heavy 6S 5-inch freestyle and racing drones. Moving away from the flat magnets of the original ECO series, the V2 introduces N52SH curved magnets to deliver tighter stator clearance. This translates to noticeably sharper throttle response and higher low-end torque. It retains the accessible price point of its predecessor while drastically improving bell durability and magnetic circuit efficiency for modern FPV flight.

Key features

• Upgraded N52SH curved magnets for higher torque and tighter clearance compared to flat magnets.
• Robust 9x4x4 mm EZO bearings to maintain smooth operation and longevity through heavy impacts.
• Strengthened hollow steel 5 mm shaft with standard M5 prop threading.
• Machined aluminium bell with a rounded profile for enhanced crash resilience.
