Nova DVR XP - anyone running theirs on 220V?

I got the lathe last night and love it, but want to go 220v..

The manual says that it will run on 110 or 220 and implies that it eats whatever you plug it into.. I'm thinking that there should be some wiring or jumper change involved first?

The closest info I could find was on the 3000 dvr, showing them pull the back of the headstock off and removing a jumper.. There is NO mention of this in the xp manual...

I've always had to change the wires in the starting capacitor before, but this motor doesn't seem to have one??

Any help appreciated..

I'd follow the directions. From the theory, there being no starter capacitor or windings, it shouldn't make much difference to the motor, only the controller. Tim Geist is the US rep for confirmation.

That's my problem, George.. no specific instructions and the manual sucks.. I'd hate to follow the instructions on the web page for the 3000 DVR and harm the motor.. which would be MY fault, of course..

I emailed tech support, maybe they'll help..

Back in the old days, I recall that Lyn M. talked about a jumper on the circuit board that related to this question. It's certainly possible that this is no longer applicable, but I wouldn't take a chance. Isn't there a nameplate on the lathe that specifies the voltage(s)? When Lyn wrote a test report on the lathe, he said it was more robust when running on 220.

BTW, does anyone know what fate befell Lyn? Last I heard, he was having serious breathing problems as a result of handling contaminated wood. Arch? Fred?

Try Tim Geist, if you haven't already. He is the Nova agent in US (right next door to Woodcraft). snipped-for-privacy@aol.com I did not have much luck emailing him but I called him and he was very helpful. 304-295-8166.

Thanks.. I'll give him a call if tech support doesn't have the answers..

Yep.. says that the motor is 1.75 hp @ 115v and 2hp @ 220v.. Every machine that I've changed before had 4 wires that had to be reconfigured.. something like 1&2 connected and 3 & 4 connected for 220v, 2 & 4 connected as a jumper for 100v?

Lyn was the reason I bought my Nova 3000. He ran that lathe through its paces and then some, pointing out the good, bad and the ugly about it. He was a tireless writer, tester, and proponent of all things turning. He called it like it was and I thought he did some great, balanced reviews of different machines and equipment.

I think Fred H still keeps in touch with him. I know he is still talked about from time to time on other venues like WoodCentral. I think the last time I saw a comment on him a few months ago he was bedridden, but alert and active (mentally). If you hear something, I hope you post it.

I think the only one I can think of in recent memory that is as detailed (maybe more so) and tireless would be charlieb. I was dumbfounded at his attention to detail in testing the Festool Domino and the fact that he put up a better tutorial and instruction page than Festool themselves did. And I see him in other places as well, hammering out the details on tools that are often overlooked by others.

I guess the biggest difference would be that Lyn was focused on woodturning, and charlieb is focused on anything that catches his eye. (You go, Charlie!)

A rotating magnetic field is generated by a computer, opposite in direction to the rotation of the lathe. The field moves backward to a position just ahead of where the rotor poles need to go, and the rotor goes there. For faster rotation, the field moves backward less. That's how they get variable speed. According to all reports, this direct drive lathe has unmatched smoothness.

Unless Fred has heard from him in the last couple of months.... As of last fall it had been months and months since anyone had heard from him. I worry more and more as the months pass

It's very smooth, Leo.. I turned a few small boxes and it was amazing how smooth it was..

Then, this morning I put a foot long piece of 6" dia. oak branch on it and found out that I need to really work on the stand.. LOTS of vibration at some speeds, very little at others.. I'm not sure if it's the harmonics of the stand or the balance of the wood, but, for example,250 rpm was very rough, 500 was ok, 750 was even better - almost smooth, 900 vibrated worse than 250..

I'll add a shelf as soon as I can get to a lumber source.. then maybe leveling feet.. I really don't like the way the stand came, with no feet or pads, just the 2 sides and a top.. lots of bare metal on the floor surface..

That would be harmonics. Dampen them with the plywood as in the modification on the Nova site.

You're interested in getting the feet firmly on the floor, so don't bother with things like isolation mounts which will change the harmonic characteristics and nothing more.
