I have a home made unipolar stepper controller using the UCN5804B. I got three matching motors off ebay for $6.00 ea. the motors are marked:

Superior Electric / SLO-SYN
1.25v
3.8a
Hold 60 oz. in.
200 steps

I am building my own design table with a working area of 18" x 18". Here are my questions:

1 - Will these have enough holding (60 oz) to do the job.
2 - Since they are rated at 1.25 volts and 3.8 amps will I still need to use high wattage resisters if I go to 12 vdc, and if I do, what would the value of the resistors (Ohms and Watts) be.

Thanks,
George
