ESjaavik,
Thanks so much for your reply. Please excuse my ignorance but I still have some questions.
When you say choose the highest voltage I can afford, does this refer to the motor or the driver, or both?
I can see Ohm's Law becomes more difficult under AC conditions since one must consider frequency and indictance of the windings, etc. in calculating the impedence of the stepper. It is good to know a chopper drive will ballance current requirements.
Thanks,
Thomas |
