Calculations needed for spur gear drive


Tom Gideon
 

Hi,
I'd like to configure a system for (ok...) a Criterion 4000. It's been refurbished and the optics are actually good. The main gear is a 217 tooth 48P gear being driven by a 13 tooth gear attached to a .75 RPH motor. I had to replace the motor with a 220VAC unit and I'd just as soon do away it.
I've been trying to figure out what stepper motor configuration would work and I'm stuck. Any help would be appreciated!
Thanks,
Tom
