Nice little IMO inverter, very reliable and reasonably priced...

Ah I see, that looks good

The programming taxed my poor old analogue brain but apart from that, all good.

I can advise on what to buy if you need help......
Pockets dont have to be that deep, I am looking at finally converting my lathe to a three phase motor and Transwave can supply a motor, direct fit, VFD and control panel for 360, all I do is fit it and programme the VFD to my requirements.

Definitely. My lathe was appauling during the time it had a single phase motor on it.
I now have a vfd on it.

I think your catch plate might be that big piece of chequer plate behind the lathe.
It is worth having and worth keeping clean to reflect the light around the work.

Well there's a thing
Not seen or used one of those before.
I guess you clamp your work to it with half a dozen G clamps and then go for 3000 rpm
Less dangerously.. i guess you turn things between two centres and use that as a drive

Just done this with my Boxford. I bought a cheap vfd from eBay for 90 and installed it myself. I have the same motor as in your picture. Be aware that it is 415 3 phase even though it says 220 and 415. It wasn't just a case of changing the three bars over to make it 220v. I had to take it to a motor rewinder to change it over. Didn't cost a lot though. It's the difference between star and delta. I'm no expert.
I would definitely keep it 3 phase though, variable speed , reverse and motor braking are great.

Thanks Brian that is useful info.

I have spoken to Drivesdirect.co.uk, and basically if the motor is dual voltage (e.g. 220/415V) then it can be driven at either voltage. Of interest is the horsepower, that will determine the size (and cost) of the inverter required. I may need a new "pot-in-a-box" (whatever that is). I will need to know how to change over the motor voltage, so that would be good info ?

Basically I need to get the lathe home and in the shed so I can see what I have got.
