    Cool Stepper Motors and Voltage

    The more I read, the more confused I get! Is it ok to run 24v into a 1.8volt motor? Is there a % of maximum volts you can run into a motor for its volt rating. I have 4x (1.8v 3a) and 4x (24v 4.4a) stepper motors. Both lots 6 wire. How many volts should I put into the motors to run a small hobby mill. Im running a "4xcnc10b" driver which handles 10 amps per phase per motor. (dtllc.com). Also, is it a general assertion that the amp rating on a motor is per phase? Any help would be much apreciated!

    Yes, the amp rating is per phase. I wouldn't go much beyond 15x the motors nameplate voltage rating.
    If it's not nailed down, it's mine.
    If I can pry it loose, it's not nailed down.

    When you use higher voltages with that driver board, you'll have to use resistors to limit the current to the motors.

    when a higher rated voltage is applied to a motor and the rated motors current met, at this time the voltage applied should be backed off to its opperational rateing or untill its maximum current is met, otherwise the windings will get to hot and start to melt of arc.
    a higher voltage makes the motor go faster. you don't get much more torque as usually the saturation point is maxed out at the rating on the motors lable anyways.

    The higher voltage provides more torque at higher speeds.
