Three Phase?

[whisper]

Three red wires, a black and a green. How hard can it be???

Drove me insane that we had to build a machine for a couple of weeks to do a job that would have taken us 5 mins

But it was like growing up in the A Team.

He retired through ill health due to his heart and was very frustrated at home but he wanted to build the best workshop ever but filled it with projects.

Sadly he died just 4 weeks after he found out that he might have cancer. it's a tough challenge sorting stuff out, but I enjoy remembering the things we used to get up to.

A few days before he died I got his land rover and parked it next to the room where his bed was and we snuck out and I drove him round his field and showed him all his stuff. When he was asleep I had been out there cleaning up the place and he said he was so proud.

He said he had lots to tell me but he died two days later so he never had time.

Sorry mate, didn't mean to stir up difficult memories by asking what he did....
I went through a similar thing 13 years ago when my old man passed away 5 months after going to the doctor complaining about shortness of breath.... I was 27 at the time and he was just 57 ;-(.
I can certainly relate to what your going through.

It's ok, I'm ok. Just need to sort things out now

If you talking about the output from the converter then check to make sure the 'green' wire is not actually a yellow and green earth wire first. Use a multimeter set to resistance to check you have continuity between it and a metallic point somewhere on the converter frame .
The black wire will probably be a neutral and fir the most part can be ignored at this stage
The three red wires will be the phases ( although its rare to have 3 identical colours used for the 3 different phases)
Plug the bench grinder in first connecting the three red's .to the three wires from the grinder motor that are not the earth wire. ( find the earth in the same way as you did fir the converter) uf the grinder spins in the wring direction, simply pick two of the red wires and reverse them to the wires connected to the grinder motor....

See.... Simples

If your not confident, ask a friend that knows a bit about electrics.... Normally its not difficult to work out which wire us what.

Whisper - I think the best thing anyone can say about their Dad is I miss him now he's not here anymore, and the worse thing someone can say about themselves is I wish I'd spent more time with him.

Keep smiling mate, he's not really gone if when you think about him it brings back happy memories.

Thanks dude

Compressor.....

Found a 240v grinder, compressor, bandsaw and motorised hacksaw.....

3 phase converter....

as my old mate used to tell me, when I was an apprentice, " it's dead easy black to black, red to red, blue to f--k", he still tells me the same now nearly 39 years latter

[Ribtecer]

If you decide to sell bits off, I'd be interested in a single phase bandsaw...

Just thought I'd mention it.

Hi Alex
The wiring is simple, you hve an earth and the three phases....

Looking at the size of the donkey motor your converter is probably a 5 or maybe a 7.5KW unit. You should be able to run most things off of it.

Obviously if your going to try it, make sure you can plug it in to a sufficiant supply as if its a 7.5Kw machine it will need at least 32A.

Run the grinder first as i mentioned earlier. Dont worry about connecting the wires up as long as the earth wire from the converter is conected to the earth wire of the grinder. Check the rotation of the grinder wheels and if needed reverse the connections on two of the phase wires. This will reverse the rotation of the grinder wheels. Its important to get the phase rotation correct as otherwise you could drive machinery the wrong way round which in some coases could cause damage. A simple bench grinder is a good way of making sure this is correct.

I started off running our workshop off of a converter (7.5Kw) but outgrew it a few years ago. I had to invest in a dedicated 3phase supply which meant laying in new cables up to a distance of about 75meters.

Im sure if you decided to sell it, somebody on here would have it as they're normally quite sought after second hand.

Hi mate the motor says 4kw

Had a chat with me mum and she says I can start getting rid of all the three phase stuff if I want to.

[whisper]

Looks like we don't have the correct supply to run this stuff and the fuse box is 100 yards away so it's not worth it.

I'm going to keep the 240v stuff but will sell all the 3 phase stuff as soon as I can find out how much its worth.

Please let me know if you have any ideas

May be interested in a px for any tools for building stuff out of Stainless Steel tube

[Rokraider]

I might be interested in some of the 3 phase stuff, can you do a list with some pics?

[whisper]

Ok here we go.....


Saw bench, no motor has been left outside, very heavy and solid.

Startrite 3 wheel band saw, been left outside looks complete but will need work.
