havnt got 3 phase
Looked at inverters and rang a few places but they keep saying i need to wire it do the motor, problem is it has a basic computer that gets power from somewhere so need that to work too. The computer has a note saying use 240v fuse but does that mean it will be single phase? so can wire seperate?
Every company i rang, i said "can i not have single phase in to your inverter,then the output of the inverter wire to the mains power socket of the machine", but they say no?????????
Depends on a lot of things really.yes you can run the computer independently from the machine however there may sometimes be control circuit issues as there maybe an emergency stop or something wired in through the computer,although that's unlikely but not unheard of.ensure that it's not hard wired before you bring the 240 supply from elsewhere as it could go bang,usually 240 fed machines use a kettle lead wired into the machine panel somewhere.
With most industrial use,240 is found via one of the three phases and a neutral,the amount of pricks I've seen try and get 240 by going phase to earth is scary,you just get a loud bang and live framework then!!
Judging by the colours you've mentioned wiring wise,it's quite an old machine,modern three phase is brown,grey black and of course blue neutral,yellow/green earth.
Could you say what machine it is? Dependant on the current the machine takes will determine what converter you require,there's loads on eBay ranging from £100 to £1000.
Quick note,if you start it up and it turns the wrong way,swap two of the phases around and it'll turn in the other direction.
