Im not in the thick of it yet... more just hoping and planning ahead (which is really against my nature )
Might be moving (home shop to BIG home shop)
Problem... I have a few 3ph machines...
Current setup:
Okuma LC10 CNC Lathe is at a friends shop who has 3ph 208v (manual says requires 60 amp breaker - has large DC spindle motor)
K&T 2H Universal 5hp 3ph is at my uncles shop with "B" phase as the local utility guys call it, which is supposedly just old style 3ph.
Wells Index 745 1hp 3ph that has a leeson VFD 2hp at my house running on single phase through the VFD.
Various other Single Phase machines and such...
Would end up moving it all (if all goes well) into a shop that has only Single Phase. So the generation of 3ph would become an issue.
So I have at hand a couple problems that I am in the midst of researching...
If we get this new place, funds will be tight which compounds the whole mess....
I dont know for sure how to figure out my requirements for total supply (and an added margin for expansion) primarily because of the Okuma. If I remember right, the DC motor is 13kW and I think max 180 or 200 volts DC plus the control. But I dont know what that would convert to in regards to idler motor size.
More info on the Okuma:
Okuma LC 10 with OSP3000 control
Has a transformer wired permanently to it, that can convert a range of 220 to 480 - and its output is supposed to be between 200 and 205 volts for the machine as per the Okuma Tech that helped me set stuff up. I am unsure which leg the control is on, but I would think I could figure that out with some hard core wire tracing. Manual calls for a 60amp breaker for the unit.
So now on to what Im trying to figure out...
Can the Okuma Control survive on RPC generated current?
Will that transformer help to stablize or condition the current from the RPC making it more likely be an okay setup? (Id assume good tuning on the RPC will be a must)
How much Idler HP would I need to feed the Okuma? (I seriously doubt I could ever come close to maxing out its draw... but Ive learned to never say never )
How much would one think would good as far as over estimation? At some point Id like to add a VMC - Robo-drill type machining center to the mix and if I did, the odds of both running at the same time is pretty high. But if the two CNCs were running odds are the manual machines would not be on at the same time.
Im sure there are a lot of things Ive failed to even think about... and am open to suggestions of other areas that need consideration as well as any input or advise on any and all that anyone is willing to share.
Thanks in advance....
