Re: Source for servos or steppers

Miguel,

you are correct about the 28-29 in/lb range on commercial machines
being adequate.
My motors are 40 in-lb servos. I was lucky to acquire a few of them
at a decent price. Also my AMC amplifiers use 170Vdc. Running both
servo's & amps at 170V dc makes a nice combo capable of over 300 ipm.
I can machine all day & the motors are warm (room temp) if you touch
them, that gives me lots of "headroom" & some might say "overkill"
