Re: Motor vs. Servo

Since the motor is connected ridgedly, through the lead screw, to the
work, how does the inertia of the work affect motor inertia? A
bridgeport table must weight several hundred pounds and is sliding on
gibs. Driving a high inertial load with a low inertia motor seems to
be inefficient. If we were doing pick-and-place with a mill table,
then a fast motor would be necessary.

The next question, given a typical feed rate and screw pitch, what is
the minimum motor characteristics required. High speed slew is not
necessary for a home machine.
