servo motors ?

[vertcnc]

I am in the beginning stages of building a 30" x 60" all aluminum gantry router to be used for wood and aluminum.

My original plans were to use steppers and Gecko's, but as I follow several of the projects it seems that servos are the way to go.

I have 5/8" 4 start ball screws with anti- backlash nuts. The motors are going to be connected to the screw via timming belt, So there is some room to adjust the ratio. I looking for speeds around 80-120 ipm with good resolution.

I found these motors and looking for some help. I am totally lost on the some of the labeling.

Reliance Electric Dc Motor

Torque Constant, Kt=5.75 Lb-in/Amp
Nominal Speed Rating 1750 rpm
Nominal voltage Rating 120volts

500 line encoder

Thanks

They did seem a little stout for my application. I was looking at them mainly because of the nema 34 frame and I aready had some parts machined to mate to nema 34 steppers.
I keep looking for something a little smaller.

Thanks
