I don't have any datasheets for them the machine was purchased with them on, on the end of the motors it says FL57STH76-2808B, 1.8. 2.8A/PH they look like the Nema double 6mm shaft motors and they look new, if this helps.
The controller for them was a cheep looking thing called (Aliencnc) and the wiring just taped together hence the reason to build a new setup.
