It should act like a pump .If you throttle the discharge decreasing the air flow the amperage should go down which is exactly what they do on large air handling units used on HVAC units .
Regarding single to three phase regardless of the voltage a rotary convertor should work .If you had enough transformers you could build a bolt of lightning but it would an electricians nightmare . All that said once again it's nearly impossible to trouble shoot anything over the internet unable to see it .It's often just an educated guess which may or may not solve the problem .

Thanks for all the good post guys, you hit the nail on the head. they are really complicated grafics, normally a motor if it works more it draws more amps, but there is a sweet spot in blowers where with shavings it first goes down and then if you really overload it with material it will draw more.

As the fan has cero restriction on the exhaust side and very little tubing in the inlet side (6') the fan is spinning freely and drawing more amps, 8.8A, but the suction is really there, way more than with the cyclone in place.

I will give it a try without restrains, check amps under load and check if the motor gets warm, if not i take the chance and go with it.

I'm not going to dig deeper in the motor rating

380V at 5.9A = 2242Watts = 3hp
220V at 10.2A =2242Watts = 3hp

IMHO using the VFD to run a 3 phase motor on 1 phase power is a great way to do it, it should be more efficient than a rotary phase converter and much easier to setup and maintain.

Al_Smith · June 17, 2022, 10:19:54 AM

As a comparison while a VFD usually works well it's rather complicated but a rotary can be DIY with a motor and a couple of capacitors .It all depends on what you have and what you understand . European is one thing but Japanese is a horse of a different color .You have like 200 volts phase to phase and 115 phase to ground .At work on some of those machines we had to use auto transformers to make them work from 480 volt delta supply voltage .I could never understand why at some point everything was not changed to a universal voltage .
My shop is 240 volt 200 amps single ,However I have 480 single using two 120 to 480 transformer wired backwards and 3 phase via a rotary and them through a 3 phase step down to 240 3 phase .I have a drill press plus an old Bridgeport mill that have 240 volt 3 phase motors .Then a 240 single using a 24 volt transformer to get 264-266 single which will fire 277 lighting .It's actually a tad higher because my incoming is around 248- 250 volts .Some place in my junk I even have a couple of 200 volt Japanese transformers I doubt I'll ever use .Like most of everything else they were free 8)

So, 390Volt at 7.2A = 2800 =3.7hp
or unrestrained
390Volt at 8.5A = 3315 = 4.4hp

motor says 4hp , so i think i'm fine

Passed 100 boards thru the moulder yesterday, first 40 boards went ok and then the HSS straight knifes lost their edge and it went bad from there, heads bogged down, to much amp draws, tripped brakers and burnt wood came out, :D. the straight knife heads are total rubbish, spiral heads are bought and shipped from taiwan, very good supplier and cheap, if anybody is interested. high quality aluminum insert spiral heads.
First thing learned, i needed a mitter saw aside the moulder for pre lengthening boards, found that on fb for 200$ and did a nice table extensions. second, 1" thick boards go thru perfectly, this 3/4" boards started developing terrible snipe. so i planed them a little thicker and pass them thru the one side planer to finish, did install new cutters, glass smooth finish.

But the workflow is pretty awsome, put a pallet wood left of the mitter saw, cut to lenght pass them right, to the forklift, then in they go thru the moulder and pile up on again

Teakwood; you've been working hard, good progress!
The world famous "sticker police and shop cleanliness force" will no doubt be impressed with your facility.
Me, I'm drooling over all that gorgeous teak. 🤤

I love Walnut but wouldn't mind having some Teak in my woods!

Not a thing wrong with that start. Looking great.

teakwood · June 24, 2022, 08:10:06 PM

Look at the deal i made :D :D, but this is the last piece of equipment i buy for a long time, i have spent way to much on all these updates. Well, it's an investment, will pay me back multiple times over the next 20 years. As the wood sales of the past payed for a lot of the quarry permit expenses now the quarry is paying back with this investment to the lumber business. ;D

I was in negotiation since 3 month with this guy, had the thing laying around in a storage for 3 years, planer never touched wood before. the guy is broke but still wanted 11k for the unit, this is way to much cash for me, so we started making deals. finally he acepted, 3500$ cash, my old 20" grizzly, a double drum sander 25" (which i do not use anymore) and still had to put 700$ of teakwood into the deal.

But i got this: Grizzly top of the line Extreme Duty Planer 25" G0603X with all the bells and whistle, that thing weights 1 ton

and this is what i gave the guy

there is a possible wood sale from my north american client, like 10ks in panels, lots of them 24" wide, that's why i wanted to update for a long time ago already.

I kinda had it with the sticker problem, you put a pile there then next thing they're in the way so put them elsewhere and so on. pallet for stickers

rusticretreater · June 24, 2022, 08:20:46 PM

Grizzly still sells the unit for just under $13K. Usually, I only go 1/2 price for used equipment. This is a few years old but never used. I would place it around $10K in value so you got a really good deal.

Ad at least 5k for shipping to CR, import tax and national shipping. Everything is more expensive in CR. So the deal is even better :D. But I will also spend 1200$ extra for a rotary phase converter

customsawyer · June 25, 2022, 05:14:12 AM

I think that is a good deal. I've never ran any Grizzly equipment but lots of folks like them.

teakwood · July 04, 2022, 07:58:32 AM

Started to rearrange the workshop, put the small planer in the back, maybe i still need the old planer for some small stuff or when it's just a few boards, so i don't need to start rotary converter and the big planer. probably offer the old owner of the big grizzly planer some cash so i can hold on to the old 20" planer.

All my planning and guessing the future turned out perfectly, got the big panel order form my "gringo" client, 17k in panels and loose boards. so the 25" was the perfect buy at this point :D

the pass thru is getting smaller but i think i'm ok, what really annoys me is you can't put wood on top of the new planer, bad design from grizzly. normally we pass wood form the outside over the planer to do another pass.
another bad thing is the digital control panel should be movable form one side to the other, or be more integrated into the machine, i just see the first board hitting the panel, it's totally exposed.
i'm kinda thinking to do some protective structure over the whole thing but i haven't came up with any intelligent idea yet ???

did a nice wooden base for the phase converter

Finally had the time to make a cabinet for the moulders vfd's so they don't eat dust

Don P · July 04, 2022, 09:33:54 AM

You don't waste time

. The cover looks great, and then I wondered how much heat those put off?

We usually use roller tables or carts to stage wood around the planer. I've got a pair of them running for 20' on the off side of the planer now. Run a stack, roll back to the front for the next pass.

teakwood · July 05, 2022, 07:47:18 AM

i will see about the heat in the cabinet, i did 5 holes in the bottom for fresh air inlet and one big hole on the top right side, hope to create a air flow which expels the hot air on the upper hole. put some fly net over them so the bugs can't come in. also trying to not let to much dust in. if that doesn't work will need to incorporate small exhaust fan and some inlet filters.

i'm planning on making a roller table for the planer

teakwood · July 06, 2022, 07:36:03 AM

All set and done, this planer is a beast, eats wood. before the fastest gear was 20ft/m now it's 30ft/m, so i'm working faster. also it has a subdivided infeed roller, that means i can feed 4-5 pieces at the time and not just one or two like with the old planer.

several things are already showing up to be bad design from grizzly. the 5" suction port is too small and the funnel inside the hood is not sealing right against the cutter head. lots of chips thrown out and not going into suction. and max cutting depth is only 1/4 and it should be 3/8.

the automatic table raise and lower is awesome!

A electrician made this nice panel for the rotary phase converter

I did one roller table and the thing is worth its weight in gold, but then i quickly realized i need a second one so i can pass the planed board back to do another pass, so i did another one.
Dang am i happy with all the new updates, boosted my panel output by about 25%
