3 phase stepper ?

[64dodge]

I'm gaithering parts for hobby cnc have most of mechanicals , ballscrews , linear guides & rail , table & gantry. Working on electrical now. Theres some 3phase oriental steppers with gear reducers at work that were taken off a job and are about to be tossed out. Supervisor says there good but just wrong. Would these be good for use on a hobby cnc if they are the right size or be better another kind such as 2 phase? Dont know much about this I'm a machinest.

Thanks

Found out today these arent steppers but induction motors.
