One more about Phase Converters..

[l u k e]

Looking for a "round about" price for a phase converter for a Haas VF3B with a 10,000 rpm spindle and a 30 horse motor?

check out phase perfect phase converters. the 30 hp version dpc-30 is about 6000 as i recall.. works like a champ..

cheers!

Or you can go cheap and get one for about 1/4 of that. Is the Phase-Perfect truly perfect? They'd have to make a really good case for me to believe it.

After spending dozens of hours (literally) looking at my incoming power on an oscilloscope and researching RPCs, I have to say that there are only two, truly 'perfect' solutions:

1. A mechanical motor-to-motor generator setup (a single phase motor, spinning a 3-phase motor). That will generate true 3-phase power without phase shift.
2. An external vector drive with huge banks of capacitors.

A Phase-Perfect or Phase-a-matic would be a very nice phase converter--if you can and want to afford it. Are they 4X as good? I didn't believe so. But don't let the $6K price tag scare you out of buying a machine. If you can't afford or justify that expense, you can get by at $1500.

It's the whole Chinese tool vs Snap-On conundrum. Is there a difference? Yes. Do you need it? That's up to you.

Thanks for the help.
