Servos?

Yes




Then why exactly do you need gecko drives?


Seems all Gecko drives accept is stepper input, which is the basic
output
from EMC....however, Gecko also has drives which will drive a brush
dc
servo.

Allows you to also toss the existing drives by eliminating the need
for
additional DA converters or motion cards.

Actually EMC natively supports servo motors and analog amplifiers.


Cant find that at the moment then I guess..

lemme go downstairs get some numbers then

BRB


Motors :

Glentek GM 4040 motors brush dc with 7v/1000 tach and 2500 pulse encoder

What s the voltage, amp, and RPM rating of those?


torque 500 in oz

cur A 9.1

res .8 ohm

ind 5.6 MH

BEMF 41 v/1000 rpm

max rpm 2400

Great motor, very close to servo motors on my Bridgeport (3.4 N-m =
2.5 ft-lbs, same as yours).
