I have searched the files (and the rest of the internet) in quest of some info on the old Amtek/Lamb Electric 50 volt DC motors used in the old tape drives. I have a couple of them and hate to let them languish when I have plenty of places to use them.... But, I need to have some idea of what they will do and what kind of power they need to do it.

No, this is actually ON topic for a change. These motors are probably
quite good for most purposes.
They had a little higher armature resistance than I thought was a good
idea for commercial use on
a Bridgeport Series-I size machine, but will almost certainly work fine
in hobby use even on that
size of machine. These motors were wound for low RPM, high torque use,
which is a bit rare
in servo motors, but ideal for CNC'ing milling machines and lathes.

I think some people have used these with Gecko servo drives with good
results. You could also use them
with Westamp, Servo Dynamics or Copley Controls servo amps, and an
analog-out servo interface
board like the Servo-to-Go or my PPMC board set.

What sort of machine are you planning to use them on?
