Ip is peak current, Tp is peak torque. You will have a big problem
finding affordable
servo amps that can run these motors up to the peak torque! 230 V * 63 A
= 19.4 Hp (peak)!
230 V / (27.8 V/krpm) = 8273 RPM. Running a 5 TPI screw at 8273 RPM
gives 1655 IPM
feedrates! Yikes! I think you can run these motors on 100 V, or even
less, and still have
plenty of speed.
