I unloaded the 4000lb chunck of iron yesterday. Looks like its all 3 phase. Need a 27kw rotary phase conveter now to run it. Even the servos on it are 3 phase. And huge. Wonder about sticking some nema 42 dc steppers in place of the ac servos. What about a dc servos and gecko 320s. What to look for. How to size them so they are same torque etc?
