Im new here so take it easy on me if i sound stupid. Anyway i have three slow syn unipolar stepper motors i came across that have the following specs.
2.64 volt
5.5 amps
450 hold oz ( thats a lot of torque )
Looking around i can find somewhat inexpensive drives for low amp but nothing for this high of amperage. I see there is a schematic for a higher amperage drive on this site that can be built somewhat inexpensively and ive built my own curcuit boards a time or two before but they never come out very good . ( they work , well sometimes they do ) Does anyone know of a fairly inexpensive route that i could get some drivers for these motors? Also if anyone here might have an excess of drives that will work on these i can come up with more of these motors and maybe we can work out a trade or something.
