EMAX ECO III Series 2207 1700KV Brushless Motor

This motor is optimized for 5-inch propellers, such as 5040, 5045, or 5050 tri-blade designs, on 3S to 6S LiPo batteries. The 1700KV rating provides a versatile balance, allowing for efficient cruising on lower voltages and aggressive power on 4S-6S. Always ensure your electronic speed controllers (ESCs) are rated for the corresponding current draw.

Yes, the EMAX ECO III 2207 1700KV motor is fully compatible with 6S LiPo batteries (25.2V). Its electrical design, including single-strand windings and N52SH magnets, is engineered to manage the increased power and RPM. Ensure your ESCs, propellers, and frame are also rated for 6S operation to maintain system integrity.

The motor utilizes precision G1-grade ball bearings for smooth operation. Maintenance involves periodic inspection for debris and applying a drop of lightweight bearing oil (e.g., sewing machine oil) to the top and bottom of the shaft where it meets the bearing. Avoid over-lubrication, as excess oil can attract dust and grime.

The 5mm shaft is made of hardened steel and is press-fitted into the motor bell. While durable, a severe impact can bend it. Replacement requires specific tools and skill to press out the old shaft and install a new one without damaging the bell or magnets. For most users, it is often more practical to service the entire motor unit.
