Product overview
The DYS BE8108 is a brushless outrunner motor intended for multicopter propulsion. Its physical architecture combines a CNC-machined shell, Japanese NSK bearings, 0.2mm Kawasaki silicon steel and 40UH magnets, as described for the BE series. For installation planning, both published winding variants have an 86.8mm diameter, 26.6mm length, 8.0mm shaft and 240g motor weight. These manufacturer dimensions provide an initial integration envelope.
Procurement should identify either the BE8108-16 at 100KV or the BE8108-12 at 135KV, because their current, power and pull figures differ. Both specification blocks list 6–12S LiPo operation and an unexplained NP configuration designation. The separate load tables report operating points from 14.8V to 25V with carbon-fiber load designations; their pull figures remain tied to those conditions. A motor component without an itemized accessory package, complete aircraft configuration or airframe kit. Confirm the selected motor, propeller, controller and installation details before procurement.
