I have information
Manufacturer: Komo
Tooling: HSK63
24,000 RPM
Cooling: Water
Auto Drawbaw
Encoder Feedback (encoder not included as they were not present when we got them.)

he has 0.2 Ohm between 3 motor phases
Whitch is nominal voltages and current?
Air pressure for ATC ( do connector named "KR")?
Water connector? Conus air connector?

Thank You!

I got one of those spindles off eBay. The seller told me its a HSK-63 but at least the one I got is HSK-50E or HSK-63F (not sure what the difference is) and the gripper assembly was missing. In the meantime I got that part from Ott-Jakobs (part 95.600.035.3.6) so tool-change works well. The spindle needs a 50Amps inverter. I got it running using a Altivar 66 ATV66D33N4 but its borderline and I just ordered a stronger one with higher frequency. The KR connector is to help release the tool (connects to tiny holes at the taper). The drawbar is actuated using the A port to release the tool and the B port would press it back, but I did not see a need for that as the springs at the drawbar do their job... Air pressure needs to be at least 9 bar at mine, otherwise the tool would not release reliable. Water connector would be E and F but I did not run it yet with Water... Hope that helps...
