Bought this recently and am going to install it soon.  I'm probably the only house in the neighborhood with three phase

For the industrial grade hooker-grinder-upper?

Nah,  I refurbish used equipment on the side and right now I can't afford a building.  So the easiest thing to do in order to power some of the machines was to buy a phase converter.  I work primarily on two equipment manufacturers, one is based out of Israel, the other Japan.  The Japanese tools are all three phase.

Cool!

You can get lots of good used machines cheap. 3 phase stuff can be 1/3 the price or less of single phase.

What are you going to run with it?

I'd like to get a Bridgeport one day but that is going to take up some valuable garage space.  For now just a bunch of saws that I am re building for resale.

That's funny cause i just got two 1000w hps setups from my neighbor.  I am probably going to sell them though.  They are single phase but one is selectable voltage.

Can't get 3 phase to your garage?

I don't think so.  All my uilities are underground and no industrial area is close.  I probably should have called com ed before buying this but I think having them run 3 phase would cost more than the $1000.00 I have spent.

Is that a rotary converter?

Yes, it is much better than a static converter from my research.  Why the ?  do you have a better idea to produce clean three phase power from a single phase source?

Here it is illegal to have 3-phase to a residential structure. It is just a different transformer on the pole, but new service to the structure.

So you will have a 2-P 100 running this converter, and a 3-phase panel fed by it? I assume it gives you 208 (Y) so no high-leg? How many amps does it draw to do this?

I have a 10 hp phase converter in the garage, but I'll stick with VFDs from here on out.

CONGRATS! Ill see if I can post a picture later this evening of the setup I put into my garage. Which size did you get?
I went with these guys http://www.americanrotary.com/rotary-phase-converters.html
I went with the diy pro series. I didn't need an idler motor as I got a good deal on a Baldor 10hp 3 phase motor. I have an 80 gallon air compressor, 2 table saws, 2 jointers, a belt disc sander, drill press, and a delta radial arm saw all of which are 3 phase. Believe it or not My electric bills haven't really increased much since I installed it.

Just tell us all what you expect your utility bill to be. That's what we really want to know.

I have a 60 amp panel at 240vac single phase.  I am going to run that to a starter for the 3ph motor, off the 3ph motor to a 20 amp disconnect to a 3ph outlet.  I just want to run one machine at a time on this circuit, all of my machines are rated at less than 15A.  The FLA is 26 for this unit.

This is very true. I have 2 Powermatic 66 table saws at my house. One runs off my rotary phase converter and the other (belonging to my dad) is on a static converter. I can tell you from experience that there is no comparison between the static phase converter and the rotary converter. Even if I only had one 3 phase machine I would go with the rotary.

It's not practical to run a VFD to power an entire machine though is it?

I'm looking forward to the pic!  I think mine is 7.5hp.  I have a couple machines just waiting for the juice, haven't had time to run the conduit and what not though.

Its up and runnimg but I ama not done with it. I am going to put all that exposed romex in conduit.There is the idler, phase converter, and my 3 phase panel. Excuse the mess the shop is still under construction.

That's pretty good, The starter box looks much nicer than the MEG unit I bought.  What size breaker are you running to that unit?

I have it on a 40 amp right now, I have ran multiple machines at the same time and its never tripped. I have a 100 amp service at my shop so as long as Im not running the phase converter and the welder at the same time I shouldn't have an issue.

he could get three phase to his house if they put in a three phase pad, which would cost $$$ or installed a three bank xfr on the pole and ran a quad to the house, i just dont really see why you would want to

one thing i did when i was using an idler at my country shop was to add capacitance between the  fed and wild  legs. i think the rule of thumb was 8 mfd/ fl amp. if i remember right, i was within 1% voltage wise between my fed leg and my wild leg, which really helps your motor efficiency. i was running a 7.5 hp idler and powering a cp 200 miller transformer welder.
