EMAX E3 Series 2807 Brushless Motor - 1700KV
by EMAX

The EMAX E3 Series 2807 1700KV Brushless Motor is an industrial-grade, high-velocity propulsion system meticulously engineered for large-scale 6-inch and 7-inch FPV drones. Optimized for aggressive freestyle flying, high-speed cinematic pursuits, and tactical sUAS applications, the 1700KV variant serves as the high-RPM performance choice of the E3 line. It is explicitly tuned for high-voltage 3S to 4S LiPo power configurations, providing an exceptionally punchy top-end throttle response and unmatched control authority for 4-Cell multirotor platforms swinging large propellers.

At its structural core is an oversized, heavy-duty 2807 stator utilizing a robust 12N14P configuration and a beefy 5mm bearing shaft to ensure uncompromised durability during high-stress flight maneuvers or hard field impacts. This motor handles a maximum continuous power threshold of up to 907W and manages a peak continuous current of 54A when pushed on a full 4S setup. To maximize thermal and electrical efficiency while simplifying the custom building process, the motor is equipped with high-temperature multi-strand copper windings and extra-long 200mm pre-soldered 18AWG silicone lead wires. Weighing 49.6 grams bare, this motor offers pro drone builders, commercial sUAS manufacturers, and drone racers a rugged, elite propulsion foundation built for high-speed tracking and responsive performance.
