greets all.
new & having a blast. just got my Gecko 210's and it seems
like my breakout board is taking forever to get here.
they'll be driving two steppers (6amp, .35ohm, ~500ozin) for a plasma cutter.
i've built an unregulated powersupply with a mystery transfomer. its heavy and i'm hoping it'll do the trick. on the business end its putting out 60V (no load).
by my math: V=IR so my motors are 6*0.35 = 2.1 V
my gecko tech sheet says no more than 25x motor rating so thats
52.5V.
is 60V safe or should i pull it down 7.5V with a few diodes/LEDs?
i have two terminals on the powersupply (for star wiring) that are both fused (6amp fast-blow) ... should this be ok or is there a spike when these things start that'll blow the 6amp?
any help greatly appreciated,
-anthony
