Ouch… 200V three phase – that should have been stated in the auction listing up front. BTW, for a 3/4HP motor, that should be 3.2A, not 32A!

I’d get a VFD for it, and sell the starter that is on there now to recover some of your money. While running it on 240V may cause it to run a bit hot, that should not really be much of a problem unless you plan on using it for really long periods of time – like in a production environment… shouldn’t really be much of a problem in a home/weekend warrior environment (just keep it in mind).

And, if you don’t have 240v available, you can run it off 120v. You can get something like the FM50-101 for about $125, which will take 120V single phase input and produce 240V three phase output. A sensorless vector drive, like the L510-101 would work as well and give you a few extra options, but for a jointer, the V/Hz drive (FM50) is more than enough – you would not be able to use a lot of the extras the SVD would give you.

Of course, you could always swap out the motor – but then you would not only be looking at the cost of a replacement motor, but also would need to address the starter issue.

As for restoring it – that is up to you – but from the looks of it, I’d probably just put in some new bearings, clean up and wax the tables, and start making wood chips. And this is from someone who loves restoring old machinery :)
