- Let's have a look at how my rotary phase converter and transformer are set up for three-phase ( 3 phase ) power in my 240v powered shop ( single phase ). I have lots of industrial machines and could not run without this setup.
Links coming soon for reference videos.

Cool backyard setup dude. Don't forget that you are not supposed to feed the transfos straight from the splitter as, being machines of their own, they need their proprietary cutter disconnect.
I have a similar setup at my hobby shop but Im fed up of the rotary noise and amp draw even tho I located the motor outside of the shop. Ill be going VFD soon.
You are the second guy I see on UA-cam with a 600v rotary phase converter ! not many of us ! good job.
Thank man, ya info was scarce when I went to do it. Lucky for me I know a true industrial electrician :) glad you enjoyed it
It’s a 240v rotary phase, back feeding a step down transformer so it can get go from low to high.
I made my living In industrial controls. Instrumentation and motor control from milliamps to 7200 volts. I loved going to work every day because there was always some different challenge to design, or figure something out to make it work like it was designed to work. So I enjoyed watching your video. I would have done things different but if it works for you then it is perfect!!!
It as a fun set up with lots of learning, I can see how you would enjoy it . What would you have done different for sake of learning on my part . Disconect before the transformer?
@@Wrighmachining Can't talk for him but the disconnects would be nice IMO. I would also recommend using Teck or at the very least BX wires for that sort of electrical work. Having the whole circuit running straigh in your face when you're doing lathe work would be a no go for any respectable electrician. A minimum of 3ft clearance is required in front of these devices.
this is awesome I hope to open my own shop one day with a rotary converter I appreciate your open source videos very great work
Glad you enjoyed watching . Research research research is my best advice . American rotary is pretty cool to years ago i called them with a different install and they where alot of help with everything from sizing to sugestioms :)
Funny how you just posted this video. I just received my replacement phase converter. The original one blew because I had fired up a 220 stick welder to test if it worked as someone was coming by to purchase it. I now realize that it was on the same circuit as my BP mill. You have an extra plug coming out of your box on the wall, which I should have installed for my BP. Calling my friend who is an industrial electrician to put that plug in. Thanks just in time. EDIT: The electrician who installed it was a construction elect.
Yes the extra plug has been handy. I never run two machines at the same time however.
I learned the hard way when the original plug and stuff where put in by a residential elec and past the plug was an under sized box and it went boom and it's soul escaped :)
Glad you enjoyed the video
MY HEAD IS SPINNING THANK YOU
Haha, lot to take in. Check out the notes in the video. I'm sure I put some additional links in there for reseaching. :). Good luck
Man you got a lot going on there. I run a 7.5 hp off one VFD I paid $600 for. I feed it 220 single phase and it puts out 220 3 phase. I don't know what your electric feed is but it takes about 10 minutes to program the drive and I have it on a 50 Amp plug. I use the drive to start and stop my lathe motor and the clutch takes care of the fwd and Rev. If you're interest in help setting something like that up hit me up.
Simplicity is key for sure and would love that set up. however I have 6 machines in that shop ranging from 3 phase 220, 440 and 600v. The rotary phase converter as a cheap purchase and everything else was bought second hand for penny on the dollar. I just had to keep an eye out.
I would appreciate some help feeding 220 single phase to output 3x 120V
The 3 phase 1 neutral of electricity in Asia, Europe, Africa and America:
110/170V
120/208V
208/277V
220/380V
230/400V
240/415V
250/420V
260/440V
277/480V
I think there is 575, 600 as well
Nice job🎉
Thanks buddy !
Great info, thanks.
Glad you enjoyed it :)
Nice set up ,
Thanks sweeny
Next time, flip any two wires on three phase and you get the opposite motor direction.
That is correct
I’m assuming you specifically need the Step-up Transformer to run the heavy machinery like the layth. The rotary Converter should kick out 415v without the transformer right?
I don't know the answer to that. I have one transformer for 440 and the other 600v. I'm pretty sure there is a 240v 3phase as well
The rotary is only adding a 3rd leg to the existing 240. Transfos are there to bump the feed from 240 3ph to 600 (transfo1) or 480 (transfo 2)
So the transformer is a step down transformer, but you are using it as a step up transformer? That is not recommended, one reason is the primary windings are usually wired close to the core to obtain opimum coupling, now you are winding secondary there, this will cause higher losses-in the form of heat, I would get a thermal imaging camera to make sure you are not exceeding the 150deg on your specification there.
Ideally you would use a phase convertor that ALSO steps up the voltage, if such an animal exists?
Step-down transformers are occasionally used as a step-up transformer by “reverse feeding” or “back feeding” the transformer.
Reverse feeding is simply a matter of having the power supply enter at the low voltage windings.
I have not noticed it hot at all . Infact it is way larger than i actualy need .
We have a 3 phase converter. Way back when our machines were in a cube truck. I believe it's 120v for the plug. I may be wrong though.
yes each wire of two wires for the 240v would be some where between 110v and 120v.
@Wright Machining yup. Hey, so if l1 and l2 get switched can it severely damage a hydraulic pump? We had that issue and now my hydraulics sound like poop. We did switch it back but did diagnosing with pump running until we figured it out. Also hydraulic tank was sitting at 1/3rd full and I brought it up to 3/4. Only things we did and I'm having weird sounds and hydraulics acting up
The way I understand it is that by switching two hot wires the motor will run backwards. This is the same for 3phase as well. My lathe was running backwards. Swapped two wire. Boom it's going in the correct direction
Do you know if home 220v hooked to a phase converter to make 3 phase….. what do they cash that? 220 3 phase 380 480? So confused
Ok let's explain in your regular house you have 2 hot wires going I to your panel that are 110v 115v or 120v ( you can have a variance of 10%, but you have to double check that. However I will talk about them like they are the same ) These go I to your panel and a breaker that is 110v like a TV uses just one of the legs. If you have a table saw like mine it is 220v single phase. It will use 2 hot wires. The plug is like your 110v plug but instead of 2 vertical slot you have 2 horizontal. Those 2 horizontal's are the hot wires and the mouth of the plug is the ground.
Now here is the 3phase part explained .
If you have 240v 3 phase it is basically the same 2 wires like your house but there is a 3rd hot wire on the plug Now each wire has it's own timing that will push the motor round. Think of them like 3 guys in a shop turning a single handled vertical crank on a motor. The three guys stand equally apart like 60deg and each one can only turn his handle when it's on his side. Essentially this is how 3 phase power works each part of the triangle is working evenly to spin the motor. If you take one guy\leg out of the mix the motor will not turn very well if at all, and eventually one guy will be pulling the handle as hard as he can but dosen't have the leverage to turn it.
So in follow up to the first question. 220/240/260v single phase 2 got wires with good leverage to turn it but wastes power. 220/240/260v 3 phase has 3 hot wires that all push at different times.
Now ..... As for 240, 380, 600 v
Think of voltage as pressure in water pipes. 240v is like 240psi if it was a pipe. (Different really but it helps understand the topic ) if your motor is 240 3phase it can run on a 10% variant of the pressure ( voltage ) to much it goes pop to little it goes hummmm and let's out it's magical smoke. I believe 220v 240v and 260v all will work interchangeably. You get the voltage measurement by measuring + lead on the oam meter to hot and - lead to another hot wire. Different than single phase where you go hot to neutral.
Now in different areas you have different pressures. So in the west here we have 240 and one other 440 volts. Back east I think it's 600v. Or am I mixed up :) either way like I said you have that 10% variant in voltage so a 380v 440v 480v are all in the same wheel house if in not mistaken. Just it's prefurdd that you want it close to what the motor was made for.
Now as for the phase converter part. Think of it like I said earlier, think about it like a vertical shaft with one crank handle on it and each guy using his leg to kick the shaft to spin it . Single phase 240v (with 2 wires ) has two guys on oposit sides of the shaft sharing the load using there one leg to move the shaft around . They can do it because the leverage is set up but wastes power. Now for 3 phase there are 3 guys 60 degrees apart each guy has to share the load equally. Take one guy out and it will not work right.
So we need to make power some how to move the third side. To do this we need to have an extra motor in the shop to act as a generator ( is usually 2x the size of the machine motor. ) 2 phases and spin it but the need a 3rd guy to get it started and keep it going. The third guy is a capacitor or a mechanical way of spinning the motor up to speed. Once it's spinning it; with out a load it will have momentum to spin past the missing leg of power. It will maintain its speed once it's moving at full speed and has nothing slowing it down. Once it's running at full speed it will begin to generate power where that missing side. This is where it is sent to the machine to run it. The other 2 power legs hook to the machine as well and .... Poof you have 3 phase power.
There is obviously more to it than this but hopefully gives you a basic understanding of it.
@@Wrighmachining sir, first of all……. thank you for not only answering me, but Let me just say wow! You answered me with 5 paragraphs. Not only did you take the time to write me an explanation it is very easy to understand.
Have a great day sir!
What is the power output or rms current of the phase convertor?
Botb transformers are 30 kva . In saying this that is massive compared to what is required of them . The motor is also way over sized for the lathe but i buipd things to expand them . Later if i plan to get a bigger machine ( loke i have the room , lol ) i can do that .
@@Wrighmachining Did you consider a VFD? and if so, what made you decide on this instead?, reason I ask, is I am requiring 3ph at some time.
Yes i had thought of thet but swapping out the motor on every machine can get costly. I have a rur600 grinder , surface grinder , lathe and mill
2024 NEC 210-30 b/3 super grounded 😊😂
Could you elaborate more 🙂
@@Wrighmachining just a joke . he uses phrase “make sure everything is super grounded” I found it funny but I like the guy and video I think I’ll use the super grounded again .
Hello
Hello :)
Where in hell did you get a 600v 3 phase lathe??? I purchased a 1941 Sidney engine lathe after my $300 bid on the craftsman 110v bench top lathe fell through. I had been drinking heavily from my new keg fridge and thought " ill show that stupid bench top lathe and bid on,, on,,, " fade to black.
Apparently i bid $1 over the $2500 current bid. And won! Woooohooooo.
No. Not woooohooo. I thought it said free shipping!. I live in Arizona. This mo#%\_$erfu#%:!er is located in New Jersey. And it weights almost 5000lbs.! Goddamnit. Wtf? If i had been married at the time, well i wouldnt be now. And its 208vac(3phase)! Goddamnit again. Another $1000 for the rotary phase inverter. And another $500 for wire. I put it on my porch. I no longer have a porch. I had to build a wall around it.
Kidding aside i love it. Its has a taper attachment and i can still hold +0.0002/-0.0000 on this antique. Even though it was supposed to be a hobby lathe its pretty impressive and my friends i should stop drinking. What do they know?
I dont remember what they know come to think of it.. Hmmmm..
Anyway. Where you from friend? You said "it would be something like tractor supply if you where in the states". I think only electric trains use 600v in the states. Damn. Thats some big voltage. Wtf? Your in New Zealand huh??
Good video though. Thanks fir sharing
Hahaha, from Canada BC, I'm sure you know by know drinking and auctions do not go together, haha but I'm one to talk. I built a still a few years back and had to give it away due to some questionable life choices I was making after firing it up every weekend. originally this lathe was from Spain but was purchased buy some manufacturing company out east and then by a tool company along with a surface grinder. For some reason back east they where using this power in some areas. At the time it was bought, the auto industry was slowing and they where for sale really cheap. Trucking was cheap as well.( comparatively ). You can't find a good machine out here to save your life unless you give up your first born. So we had it brought out and then with the help of some buddy's we used a pallet jack and ½ply wood and rolled it to the back shop. Best machine I have ever had, although wish I has a taper attachment like yours :). Glad you enjoyed the video!
