Hi Guys, I am just about to start renovating a 1987 Feeler FTL618 lathe ( Hardinge Copy). So that I can get this thing running on a 240volt supply I need to get a 3 phase inverter.
Do any of you have a wiring diagram and can you recommend a suitable inverter.
Thanks
Pete

Nice lathe. If the motor is 2 speed that may complicate...

Several single phase conversions have been written up over at the Hardinge forum on Practical Machinist BTW, may take some searching to find them though.

Have a look at the end of my Hardinge rebuild thread. I've posted diagrams of the VFD speed switch etc.

There's also Randy's (CNCzone.com-The Ultimate Machinist Community) Feeler FSM 59 rebuild on cnc zone (with diagrams) here:

Do you have a dual voltage motor? My HLV did not, so I had to use a step-up transformer and a 415v VFD.

Oh and post pictures or else.... ;)

OK, thanks for the info, I have read Bills stuff and guess I better have a better look at the motor. Silly me, I thought this would be a no brainer.

I'll get some pictures, should have started with the four of us getting it across the lawn on rollers, but hey! plenty more to come.

Maybe I should start a new thread and put the complete rebuild on it, what do you guys think.

I think that's the way to go.:)

I bought a Leinen lathe a few weeks back only to find that it had a 3 speed motor on it, after speaking to a few people it turned out that my only real option was a rotary phase inverter.

3HP version - 500....!!!! ouch... and that was after knocking him down on price.

Thing is I can now run any 3 phase machine off of it (under 3hp) which gives me a bit of flexibility.

Hopefully you won't need to go down that route.....

500's not that bad.

3hp going to be expensive whether take the simple route and use a RPC or go my way with switches and a VFD (it's amusing to see people's surprise at the Hardinge with a 13A plug :))
