    Exclamation Help with tuning Stepper motor

    hi everyone.

    i was looking that the manufacturer of the Nema 34 rates the min Voltage as 3.1V and max continuous current as 7A.
    what would be the max current i should apply if i'm connecting the Nema 34 with 48V? and how much Voltage does the Nema 34 can hold?

    Thanks!.

    If it's rated at 7 amps, then supply it with up to 7 amps. Torque will be proportional to the current supplied.
    Most Nema 34's can easily be run at 72V, and probably more.

    So it should be run at its rated current regardless of supply voltage?
