Re: [CAD_CAM_EDM_DRO] Kollmorgan servos

I did a little run on the Kollmorgen sizing software I have.
I got:
1.114 kw
509 oz in cont torque
1586 oz in peak torque
7.6 a cont stall current
23.1 a peak current
51v/krpm
.075 oz-in-s^2 rotor inertia

It would be a good motor for a large xy table. It is a little
big but the rotor inertia is nice and low. I don't know what size
or type of table you want to build.

Understand that you would get maximum about 1500 rpm
using a typical servo drive with 80v max output. Plenty of
torque though.

I could not find info about the encoder. might be 250 ppr
from the number. Call 'em and find out. Even with interpolation 250 is a
little low. cheap to fix if it is.

If this motor is new I would say that is a very good price.
