Reply with Quotestep-up transformer.
seams like an odd voltage if you can't find one you could always make your own by rewinding one. There's a bunch of DIY articles on the web for this.
550 volt
i am looking at buying a used machine it currently runs on 550v , i know i can supply it with 220v is there any way i can make this happen without running a new setvice ?

thanks for the reply , i am really assuming that is the voltages i am dealing with . sorry , i am a machinist . if it helps i can find out exact voltages .Originally Posted by mfgbydesign
A transformer is probably the easiest. What kind of machine is it?
Matt
its an eagle 600 made by yang iron works , it has a fanuc 0 control . it works pretty good , but the price is what i like .
If you use a transformer like this, with multiple taps, you can probably get close enough. Assuming your existing power is 220V 3 phase, you could use the taps on the transformer for 198V and that would give you 533V out. Close enough to 550V.

First what you should do is check to see if it is either a 240/480 machine that has been imported in to Canada and the previous user used a transformer for Canadian standard of 575/600?
There are very few machines made for Canadian 575 supply power and the majority have to be supplied with a transformer locally to run from a 575v service.
The basic Fanuc controller runs on 200v. The rest of the machine with the exception of any 3ph motors for coolant etc, is invariably 240/480.
Like I said, check the machine specs first, especially coming from Korea.
There should be a plate affixed to the outside of the machine with the power requirements.

i'll be there later today and i'll get the scoop . i'll post my findings
If you can get a look at the transformer on the machine you will see it has different taps for various voltages in the markets the machine was made for. The taps are terminals where you hook up the supply voltage and there should be a diagram which shows which terminals to hook up. I bet you can find a tap for your local supply. You might be able to negotiate a lower price if the seller thinks it'll only work on 550. How are they supplying the 550 now? Maybe you get them to throw in the power supply.
The machine may have been running off its own transformer.
Most of the machines we have, running FANUC controllers, had transformers mounted in the ceiling for each machine. Most likely the people selling the machine left the transformer where it was.
There is the remote possibility that the machine was special ordered with 575 volt three phase motors for coolant pumps and the like, but the actual Fanuc controller will be running on 200VAC. It is far more likely that the auxiliary equipment runs on 220/440. If not, it might be more economical in the long run to just buy a proper 220/440 coolant pump or whatever and correctly rewire that part of the control for 220/440. The odds are though that you have a 220 volt machine.
There Is a plaque on the back that says power source... Phase 3 , 220 volt. That's on the cabinet above the main power switch. I'll post a pic when I can.
That's as I suspected, if it is designed for 220v 3ph into the disconnect then all of the machine should be 220v.

Now one more question , would The 220v plug for my welder run this ? I know it sounds silly but I just don't know.
Really this isn't a silly question at all.
I have to hedge on this one. The reason is it depends upon the welder. Many are single phase others three phase. Voltage is a question too. With newer weldors it gets more complex as they are often inverter based with flexible power input. You best course of action is to get the nameplate rating info off the mill and then have an electrician look at the feeder circuit to the welder. In the NEC welder circuits get special attention so it might not meet code for this use.
My guess would be that the welder circuit is single phase and doesn't meet the machines requirements.
As a side question is this a home install or commercial? If it is a home install you will likely need a phase converter.
The plate should also have the power consumption of the machine, as mentioned you are most likely going to need an RPC, if you don't have 3 phase power.

This will be going in my home shop. The more I think about it , logic says single phase.
Thanks for the reply Al. But what is an rpc ? I just run these things , if I can't fix a fuse or breaker it's out of my hands. Lol
Rotary Phase Convertor, convert 1 phase to 3ph.
Some machines, especially with Fanuc control can be fussy on a convertor.

what other options do i have ? and what can be expected with the rpc ? is it just not reliable ? voltage fluctuation ?
There is also a static convertor, but usually more $$$.
2 phases are OK as they consist of the 1ph passed through, but the generated phase can fluctuate somewhat with load.
It is important to ensure that any 1 phase loads in the machine are connected to the 1ph 240 legs.
