I expected there to be some difference due to size of the motors,
but I didn't think it was that large. I failed to consider the
fact that servo motors are optimized for peak torque, at the
expense of continuous ratings (which aren't critical in CNC).
Industrial motors are optimized for continuous ratings. Like
the servo motor, the industrial motor has a stall torque much
higher than the continous rating (1900amps makes a lot of torque).
The big difference is that the shaft, frame, etc., and the magnets
of the industrial motor aren't designed to handle that torque,
because they don't need to in the industrial application.

Thanks for clarifying this for me. I wonder how many other
scaling effects I'll run into as I try to apply my industrial
experience to CNC on a home shop scale?
