You have a choice of start and run capacitors. Are the switches set for your motor HP ? there is an ammeter measuring your single phase current does this show any thing? It should show a huge current when the inverter is powered (30A+?) then settle back to the running current (10-15A?).

here is a circuit diagram of it if its not in your documentation :- www.clarkeservice.co.uk/manuals2/pc20_60.pdf

When it does run, this seems about right for what the ammeter is reading. it spikes at first then seems to settle.

You would be better going down the inverter route.. If your in the Reading area (RG7) I'd only too please to help or advise

Thanks for the offer, but im as far north as it gets cheeky

And thanks for the help everyone, still trying to get my head around it all. had a bit of a breakthrough tonight with the lathe though, i tried it with the converter on all setting, which puts it up to 5.5hp. the motor is 1.5hp. with all the setting on the lathe will run for about 15 seconds then the contactor jumps back out. maybe it does have something to do with the artificial phase?

Hey guys been using this website for while now been meaning to sign up for a while.

Recently bought a colchester chipmaster which is wired up for 3ph 415v. I only have a 1ph 240v supply in the workshop so i thought i would solve the problem by buying a phase converter, the clarke PC60 5.5hp converter. After wiring it all up it doesnt seem to work at all, sometime the spindle spins slowly then it cuts out, other times the contacter just pulls in then slips many times very quickly.. anyone have any suggestions?

any help is greatly appreciated.. cheers frown
