Hello
Brian from New Zealand here
I have read all the rotary phase converter stickied posts but am struggling to find a solution relevant to my situation.
First of I live in New Zealand which has the same power supply as the UK, Australia and most other former British colonies.
That being 230v phase to neutral and 400v between phases. All three phase motors in New Zealand expect to see 400v between phases. In New Zealand most domestic property's simply have one phase coming in and a neutral, as I live on a rural property I have two phases coming in.
I work at a large factory in New Zealand, our corporate bosses are looking to scrap the entire factory so I will be purchasing some of the machine shop and building a shed at home to work from.
I live on a rural property and we have two phase power and neutral coming in (I believe there has been confusion in the past as two phase means something different to you Americans. When we talk about two phase it is as below (2 legs of 3.
My two phase is from the same service provider,s 3phase line.
-----------------------phase-1-------------I DONT HAVE------
-----------------------phase-2-------------I GOT-------------
-----------------------phase-3-------------I GOT-------------
-----------------------Neutral--------------I GOT-------------
Even better just imagine I have a 3 phase line and one of them just vanished
Now how can I create that missing third phase?
Some people in the UK that only have one phase use an old choke welder as a transfomer to jump 230 volts up to 400v the use a RPC. I believe in my situation as I have two phases coming in I wont need to do this.
As I will be pulling an entire factory apart over the next few months I can basically grab any large three phase motor that I want for scrap value.
What would be the best motor in terms of poles, rpm, construction to grab? most motors in New Zealand over 5hp are wired in Delta.
The largest machine I need to power is a lathe with a 7.5hp motor, it will only be myself working in the shed so only need to run one motor at the time.
I have looked in to getting mains three phase in to our property but the price is over $20 000 nzd.
Cheers for reading
