DYS BE2808 brushless motor

By DYS ↗

The DYS BE2808 is a brushless outrunner motor for aircraft propulsion, offered in 1760KV, 1400KV and 1080KV configurations. All three share a 35mm-diameter, 30mm-long body, 75g weight and 5mm shaft. LiPo cell ranges and continuous electrical limits differ by configuration, while pull varies with battery and propeller selection.

Product overview

The DYS BE2808 provides aircraft propulsion as a brushless outrunner motor component. Its three configurations share a cylindrical envelope measuring 35mm in diameter and 30mm in length, with a weight of 75g. The mechanical dimensions include a 28mm stator diameter, 8mm stator length and 5mm shaft diameter. Construction combines Kawasaki 1200# silicon steel in 0.2mm thickness, 40UH high-temperature magnets, Japanese NSK bearings and a precision CNC-machined, balanced shell. The motor configurations are 1760KV, 1400KV and 1080KV, identified as BE2808-8, BE2808-10 and BE2808-13, respectively.

Electrical limits differ across those configurations. The 1760KV version specifies 3–4S LiPo, 36.2A maximum continuous current and 535W maximum continuous power; the 1400KV version specifies 3–5S, 34A and 629W; and the 1080KV version specifies 3–6S, 23.6A and 523W. Pull and electrical demand vary with the battery and propeller combination. For example, the 1080KV motor with 5S LiPo and a 9x6E propeller has an operating row of 31.4A, 1620g pull and 580.9W. That row exceeds its 23.6A and 523W continuous ratings.
