Its actually very simple.....connect a motor run capacitor and a motor start capacitor via some simple wiring and it'll run. ideally it wants to be a motor that can run on 240 3phase or 440v 3phase.
Have a look at my rotary converter page it has everything on their.
Many thanks for all the replies, much appreciated.
Picking up the machine later in the week, it's been stood lonely in a workshop corner for over 4 years unused, so I'll see what options are best when I get it into a decent home and give it the once over.
Hi John, as Ian has said it's not too difficult, there are three choices (1) single phase motor with a three phase generator on the end, to which you connect your machine (2) Solid state convertor (3) Invertor with full waveform & voltage control which also can give you speed control as well but probably not much use on a morticer. I've a hunch that Ian's solution is probably (2) and most likely the favorite for your application.
