    Hi all
    Any recommendations as to were I’d get a convertor to run a 7,5hp 3ph motor on 1ph.

    I have a boost energy one, works a treat. I have plumbed 3ph around my workshop and it is supplied by the phase convertor.

    You’d be better with a rotary phase converter if you want To run 7.5hp

    Agreed, and they can run other 3-phase gear as well, like when you accidentally win a big pillar drill on EvilBay...

    Pretty simple to build your own, too - you want a somewhat bigger motor, a few contactors and capacitors, Robert's one's parent's sibling.

    Corks, look at the prices! My DIY RPC cost well under £200*, does 10HP...
    I think the wiring diagrams I posted should still be on here soewhere?

    Edit of Edit - oops, that just shows the pretty control box! I'll hunt out the wiring diagrams!

    but it can be a lot simpler :)
