power output is 300w at 1000rpm, which is what the kit on the site lists. at 60v youd need to provide another torque curve (although its most likely still flat to 1300rpm-ish.
peak torque/power isnt useful to mention either unless its qualified with a duty cycle. i have parker motors that claim 300 oz in peak, but its a rating of 6 seconds with a cool down to 60C (half load for several minutes in ambient air) rendering it mostly useless on a mill axis.
anyhow, this is not the point of my comments. my comments were that the "big" motor is overkill unless you have a big spindle, and the "little" 1.27nm motors are quite adequate with the 2525 screw with the smaller spindles that most people run on these machines. and if you want to run a 10hp spindle on the demon, you may have a little more to worry about than the servo motor rating
