    can someone double-check? (powersupply)

    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......
