Al,
How can you tell all that from that chart?
But, if V/1000rpm =49.5
and max rpm = 4000
then
200v would be the maximum input for the motor, would it not?
H3ndrix, you might as well go "whole hog" and get yourself some encoders for them. You must have feedback for a servo system, otherwise you have just bought a bunch of continuous running motors: we call them runaways Some of the guys on these forums have gotten some fairly inexpensive encoders from somewhere.
How else will you get position? There are no inherent steps to the way a servo motor works.
First you get good, then you get fast. Then grouchiness sets in.
