    What Controller for Step-Syn Motors?

    I built a CNC machine 6 years ago and purchased the cheapest step motors I could find.
    It worked but the travel was 11" per MINUTE!

    It's time to build again and I have 4 Step-Syn motors out of an old embroidery machine.
    They are 103-8573-5612 / 1.5 Amp / .72 degree per step / 10 wire motors.

    Question:
    What controller will drive these things?
    Do I need a power supply?
    I have no clue and can't find anything on these motors.

    Thanks.

    Wait... 10 wires? Really?

    If you have an ohm meter, can you check out the leads and see which wires are connected via a coil to which other wires? I'm curious to know how many coils are in the thing.

    As to your new machine, I would really suggest finding some more standard motors. This page may help:

    It's a 5 phase stepper motor if it has 10 wires. You can find old Vexta 5 phase stepper drivers on eBay sometimes.

    I'm so sorry for having to ask the following question.
    Would each motor require it's own driver?

    Yes every motor requires its own driver.

    Wow. I think I'll reset and just go with a prepackaged new set.
    Too much to worry about trying to get old motors to work with unknown controllers.
    Thanks
