- I want to control a 3.9 V, 600 mA bipolar stepper motor like this, but your A4983 stepper motor driver carrier and A4988 stepper motor driver carrier have a minimum operating voltage of 8 V. Can I use these drivers without damaging the stepper motor?
- Yes. To avoid damaging your stepper motor, you want to avoid exceeding the rated current, which is 600 mA in this instance. The A4983 and A4988 stepper motor drivers let you limit the maximum current, so as long as you set the limit below the rated current, you will be within spec for your motor, even if the voltage exceeds the rated voltage. The voltage rating is just the voltage at which each coil draws the rated current, so the coils of your stepper motor will draw 600 mA at 3.9 V. By using a higher voltage along with active current limiting, the current is able to ramp up faster, which lets you achieve higher step rates than you could using the rated voltage.
