    Unknown motors specifications

    hello everybody,
    I have 4 motors that I don;t know their exact specifications and would they be useful to be used instead of steppers in my homebuilt cnc machine.
    my cnc machine is built based on 4 axis hcncpro w/23-127 steppers combo , with a rack and pinion mechanism without gearing.
    the pictures of the motors that i have disassembled from an electric water valves system are attached.
    please, may you inform me:
    - what these motors are (Steppers?unipolar?bipolar?servo motors????)
    - why they are 28VDC and 4 Amps on the outside sticker but they are 1.2VDC and 6.6Amps on the sticker inside?
    - if they were steppers , could they be driven by the hcncpro driver board? if not is there any driver schematic that i can built for?

    thx in advance
    best regards

    They appear to be bi-polar steppers, 1.2v 6.6amp.
    The exact part number did not show up but a very close version with slightly different last three digits.

    And if so, then I do not believe that they would be compatible with the Hobby CNC Pro driver (which supports unipolar motors, not to mention the current rating).

    thx guys, you are right, they are bipolar steppers, but i can,t find a DIY driver board that can handle 6 amps.
