    Question Need a new stepper

    Hi people I need help. Our rotary cnc machines nema 34 stepper motor is failing and needs replacing. I can't find an exact spec match. I need to know a few things..... If I can't find the exact spec that perameters need to be the same and what perameters can change in value slightly e.i voltage,current, step angle, torque etc. I would also be very greatful If anyone could find an eBay exact or equivalent that would do the job.no have attached all the info I know on the motor in the form of a image....

    please please help it's a breakdown situation

    thanks in advance

    You might find a motor that is close in spec on this page:
    techref.massmind.org/techref/io/stepper/linistep/motors.htm

    I've been trying to build a database of commonly used, good motors. Please consider adding motors you find.
