can someone double-check? (powersupply)

[anthony]

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

you should be okay....you won't drop the voltage with LEDs...not at the current required.....in line diodes you'd need 10 and they would have to be 6 to 10 amps....and you'd have to add some resistors across them to handle the back emf......
