Product overview
The EMAX E3 2814 is a propulsion motor for integration into FPV aircraft. Its physical architecture combines a steel shaft, AL 7075 anodized housing and one-piece outer rotor with N52SH arc magnets, single-strand winding and a G1-level precision bearing. The motor measures 35.1 mm in diameter and 45.5 mm in length. Installation interfaces comprise a 19 x 19 mm M3 mounting pattern, a 5 mm bearing shaft and an M5 prop adapter shaft thread with CW threading.
Both KV configurations support 3-6S batteries, with a 9-10 inch propeller range for 850KV and an 8-9 inch range for 1100KV. Their respective weights are 82 g and 81 g without silicone wire; the lead specification is 270 mm of 18 AWG silicone wire. Supplied hardware comprises five M3 x 10 screws, one aluminum M5 nyloc nut, and one washer and screw for the shaft. Electrical limits differ by configuration: peak current and maximum power are specified at 6S.
