Was given a pair of stepper motors by a friend and am wondering how to drive them. These seem to be quite high quality, machined aluminum housing, etc. Haven't turned up much useful information about them online; specs on device itself show:Holding torque: 80 oz/inSteps: 200 per rev2.25v, 2.25A, DC8-wire harness: blk, blk/wh, red, red/wh, yel, yel/wh, or, or/whCan't seem to track down a datasheet for this one. Electronics goldmine apparently is currently selling these, but has no datasheet available (I've already emailed them about it - lord knows I've spent enough money there to get a few questions answered <g>)It's been quite a while since I've played with these, but the 2.25v source seems odd. Can these be driven with a ready-to-run driver like the Sparkfun EasyDriver? Do these have enough torque to drive X and Y axis of a simple DIY CNC machine?
