Am building a device that will use two stepper motors and a servo. One of the main requirements, is that the on-board battery cannot exceed 9.6 volts. The stepper motors have not been picked yet, and thus I have the option of choosing one with a lower voltage.
Which method would be the best:
- Use two 12v stepper motors with a 9.6 volt battery, and simply have them run at lower voltage.
- Or, Use two 12v steppers, and use a DC to DC voltage booster to increase voltage to 12v. ( I don't know how well this would work, regarding constant current and whatnot.)
- Or, Use two 6v steppers, and use a ~6v battery. (Not fond of this idea, as 6v steppers seem to have much different specs than normal Nema17 12v ones. However, I would still use them if needed.)
