I was looking at a jointer with a 3HP 3-phase motor. I'd like to
run this from my home which has 220v. Would I be able to run it

Can you give me an example of a "phase converter" which would be
up to the task? I saw one for $89, but I couldn't tell whether
it would be up to the task or not. I imagine it might be wiser
to avoid 3-phase and keep looking, but I thought I would check
with the experts here first.

Thanks!

If it were me, and the jointers is really clean and knives in good
shape and everything looks right on the bed, etc. Then I'd check on a
single phase motor, for pricing. Check the frame size of the original
so you can get an equivalent 1ph motor and use that as a bargaining
chip. Very few people have 3 ph at home.


I like your idea. Do you know if that transition require a new
switch assembly, or are these designed to be reconfigurable? If I
want to actually "touch and feel" the machine, I'm looking at an
80 or 90 mile drive (each way). Then I would have to pay someone
who is insured to pick it up on a "flat bed truck". I've started
investigating how to get that done. Thanks, Bill

dpb gave some great advice. I don't know what type of a switch is on
the jointer so it would be hard to say, there are so many variables
that I would ask the guy first what he has and a picture if possible.

an electrician or you could rewire the control circuit, but you would
have to change the overload heaters for the 1ph motor and you would
also have to see what the switch was rated for, as the contacts might
be undersized for the motor amperage. The contacts should be inspected
to see what kind of condition they are in, not burnt, not badly pitted
or they would require changing out anyhow. and depending on the age
and brand it might limit what you can get in an electrical supply
store. WW Grainger has an online catalogue that can help if you know
what you are looking for.

Also, if you can tow, then a one way trailer could be used, but you
would have to verify that, and it would be easier to get it in a
trailer than on and off a flat bed.
