EMAX ECO II Series 2207 1700KV Brushless Motor

The ECO II 2207 1700KV motor is optimized for 5-inch to 5.5-inch propellers. This size range allows it to achieve its rated 1980g maximum thrust efficiently across its 3S to 6S voltage range, making it suitable for both high-performance freestyle and efficient long-range flight profiles.

N52SH magnets are a higher-grade neodymium material with superior magnetic strength and higher temperature resistance compared to N48 magnets. In the ECO II, this upgrade creates a tighter magnetic airgap within the 12N14P stator, resulting in significantly more torque, higher RPM capability, and a more responsive throttle curve for aggressive flying.

This motor uses the standard 16x16mm M3 mounting pattern common to most 5-inch FPV frames. The included package provides M3 screws in multiple lengths (6mm, 7mm, 8mm) to accommodate different frame thicknesses. The prop is secured with the included aluminum M5 nylock nut onto the CW-threaded 4mm shaft.

Yes, the ECO II 2207 1700KV motor is explicitly rated for 3S to 6S LiPo input. Its design, including the N52SH magnets and robust construction, can handle the increased power and RPM of a 6S system, providing pilots with a wide performance envelope from smooth cruising to high-power bursts.
