    Unknown stepper/servo question

    I've had this sitting around for years and would like to use it as a rotary for welding.. Can anyone help me out by giving me some suggestions? I'm not even sure what the voltage is or determing how to verify the voltage.. Thanks in advance https://uploads.tapatalk-cdn.com/202...fefc345b17.jpghttps://uploads.tapatalk-cdn.com/202...6fa84da621.jpghttps://uploads.tapatalk-cdn.com/202...c03c2f235f.jpg

    Looks like a stepper motor, how many wires going into the motor?

    I guess I would get one of those 120VAC input stepper drives, and a stepper speed controller. Both available from Ebay or Amazon.

    That's the plug in the pic. It looks to me all 5 go into the motor..

    Ok, I didn't see the wiring picture. So the question is that a 5 wire motor or a 4 wire motor with ground wire?

    If it's a 4 wire motor then the Gecko drive should work fine.

    If it's 4 wire with ground, then the green wire should go the the motor case, and would have near 0 ohms between the case and wire when measured with a meter.

    Sounds simple but I assure you I'm clueless... I'm watching YouTube videos now lol
