I am somewhat confused on stepper motor specs. I see a motor rated at say 5V and 1A. Most threads say run it at higher than rated voltage and you get more speed but less torque. More current gives more torque.
How do I calculate this? How do I know what my set points should be to get the best results from my particular motor?
In selecting a reasonable voltage and current for an application am I just to concern myself with the VA rating of the stepper, sort of like a transformer? If so then the ratings on the stepper seem ambiguous to me.
I just want to figure out how to go about selecting the right motors and drive system for a particular application, I'll ask torque questions later.
Thanks,
