to be honest, I would not even consider a rotary convertor these days ...

I'd go for one of the modern electronic single to 3ph convertors. I run a
3hp/2.2kw lathe on one and its just fine and dandy. you get smoooooth starts,
reversing, varispeed, DC injection braking ... the works, for a couple of
hundred bucks. The varispeed alone was worth doing it for .. the smooth
starting an low initial draw from the supply is another big plus. I know
some people swear by rotaries, but to be honest, theyve had their day. For
driving a motor an electronic convertor is almost always the way to go ...
hell, even the people WITH 3ph supplies are using them!!

I had to wire the 3ph motor from star to delta mode in the terminal block,
but that was all ... have a look on ebay for 'invertor' or 'VFD' ...
