I will grab a photo of mine when I can get to it .Info from dealing with Transwave on and off for years. Firm I worked for bought kit from T-wave, and Peter from T-wave used to refer any queries for 3ph generators (I.e. when a Ph Conv wasn't suitable) to us.
I might even still have some of Transwaves useful tech sheets on the work 'Puter drive somewhere
Well.......I was actually thinking of trying that with mine BUT it sounds like the inverter won't like it as it's not stable enough.Here's a mad question...
Could you build a simple rotary phase converter and feed a 440 to 440 inverter like the one @ukracer just bought?
I can't think why you would but could you?
I thought as much...pure guess from what's been said in these threads.The VFD might fault with under/over volt errors on the input phases.
pure guess
Oh yes, it's definitely a pure guess. It might work perfectly fine, though hanging a VFD off a rotary seems awfully inefficient.I thought as much...pure guess from what's been said in these threads.

Don’t see why it wouldn’t work, provided the rotary converted gives near enough enough volts per phase. Inverters just rectify the AC into DC anyway, then chop it up into three pseudo sine waves. The beauty of this would be the variable frequency output, and being 415 of course..
A bit of an aside, (but I am getting closer to starting):
As an avid collector of tat I picked this rpm/frequency meter up years ago out of some other kit going in the bin. Up to 1950rpm and 65Hz.

Thinking of adding it as a bit of bling. Just two 1/4" spade connectors on the back, one marked +.
How does it wire in?
But since you are running from the mains supply fitting that meter will be a waste of time as you will always get 50 Hz!
I may have some voltmeters and an ammeter to match that
I got 3 volt meters from eBay to fit in mine but they also stayed on the ToDo list for far too long.I presume you want to keep them for your own stuff?
3 voltmeters would look good, though digital might be easier to read at a glance.
Been looking at the digital ones on Banggood. Combined volt/amp/frequency meter with a 100A current transformer for less than a fiver each.
