I am using amc BE40a40ac. I am sure they are very spendy new. They are 40a peak (20cont) peak 400v max. I am using some old inland servos. early 80's I would say.
http://electronicsam.com/images/KandT/DSC_0242.JPG 160v is about what we are running for a max of 1200rpm with these servos They are about 1 amp/ft-lb - so with these amps I get 20ft-lbs cont. (calculates out to about 4tons of force at the axis) sam On Thu, 18 Aug 2011 12:52:06 -0700 "Clint Washburn" <cl...@clintandheidi.com> wrote: > I have looked at both thanks for the feedback.
