Choose motor

Hello l, I post on several forum but no answering !!
I need your help choosing motor, what do you think about LAM Technologies motor, my gantry weight will be between 55kg and 70kg, I use hiwin rails and rack & pinion system with reduction ratio 3.2:1, 2 motor for x axis* length 2500mm, 1 motor for y axis 1600mm length and z axis ball screw sfu2005 length 350mm, I want the machine to be fast and cut hard wood, I was thinking about nema 34 model M1343031*

The rotor inertia is 1550 g-cm^2 compare to other motor its low.. Is this a good thing or bad for acceleration ?*
The drivers probably will be DMS-781*
