Re: [CAD_CAM_EDM_DRO] Wanted: Servo Motors that interface to Gecko 320

I'm running 40in-lb servos on Gecko 320's. They are 100 volt (40 volts per K of rpm X 2500 rpm= 100 volts) 13.7 amps continuous. Running them at 70 volts DC to stay within the voltage rating of the drive. Sacrificing speed but not any torque. Still get rapids of 120 ipm on the Bridgeport. These actually exceed the Geckos capability but work reliably. So, anything equal to or less than these NEMA 42 motors will work with a Gecko 320. When I described these motors to Marriss at Geckodrive he replied that those are the same size motors that they test the 320 on. Except at full voltage. He also stated in another post recently that the 320 actually comes apart at 118 volts and 30 amps which is just amazing. Thats enough current in AC to power a small home. 29 in-lb or 2.9 Nm motors are very common and would be good for any X and Y axis for any mill. Most of the retrofitters use these for X and Y axis.

Hello,

I am looking for a couple of servo motors that will interface to
Gecko G320 Servo Drivers.

2 small-med sized for X and Y axis on my CNC mill and 1 med-larger
for a Lathe CNC conversion that I am just starting on. I work with
steppers motors but do not know much about servos.

If someone could recommend tourqe parameters and such, that would
also be very helpfull. Supplier names or individuals looking to sell.

You can see my Mill that I am looking to upgrade and the new Lathe
project at:

If you want to email me off-line, thats OK too.

Thanks for your help,
Joel
