Hi Steve,
<Opinionated Rant>

You've been told rubbish, solid state gives you infinite control over
speed (within the limits of your motor to cope with it), all a rotary
phase converter gives you is an expensive space consuming spinning
transformer. For me I couldn't live without inverters, plus the fact
that good ones can be had on ebay for peanuts while atavistic retards
pay silly money for rotaries is just another plus in their favour

</Opinionated Rant>

I personally prefer inverters because of the speed control, you can
individual ones on a per machine basis, as long as you aren't going over
about 7.5kW (10HP) then an inverter will be a lot cheaper. Also you
don't have to have tailored loads on an inverter, so if you're only
using one machine at a time just by one big enough to cope with the
biggest thing you use and add some plugs or switches to change machines
over and build a mobile control box to run it with....

Chaps
 
    My first post and it's a question for any and all  to answer :- Has 
anybody out there got, or used, phase converters ?. I'm just on  the
verge of 
building the new workshop for an attempt at a 41/2" Burrell but  will
need bigger 
machinery than I have at the moment, which really  means going to 3
phase. I 
have heard good and bad things abut these bits of kit  but would rather
hear 
from people in the know (as it were). I have definately  been told that
a rotary 
will be better than a solid state. ALL replies, good or  bad, will be
most 
welcome.
