I am getting ready to build a vfd enclosure for my setup. I have two vfd's, one for the drive motor and one for the coolant pump on my lathe. I am recently retired, and where I worked. we had a lot of equipment and control cabinets. I modified our cabinets and equipped them with easily removable filter media. The filters (stainless steel media and cleanable) slid in and out easily in the frame of the filter. Easy peasy. It made it so much easier to keep maintenance on the filters. My shop also substitutes as wood working and does that generate a lot of dust, even with the dust collection system.
after watching this video the first time, i ordered an ABS plastic box. Much much easier to cut the holes into and far less messy! the fan holes can be cut easily with an oscillating tool
I have too build on your Dremel comment. When I received my first Dremel tool for Christmas in about 1977, they were amazing. I even had the variable speed model (I must have been for Santa that year). I've since given my original tool to my 30 plus year daughter. And, she's lousy about taking care of tools. ANYWAY, the new super duper Dremel that I bought, doesn't even compare to my 1976ish Christmas present. I'd love to get back my original from my favorite daughter!! I eagerly await commentary, especially from the Dremel company. Scott, A 50 PLUS year Dremel Tool user.
Of all the machining/wrenching channels I watch (and I do, quite a few) this one HAS to be the first to see the words "Mandelbrot set" uttered... Two thumbs up! ;)
For anyone making this upgrade, I found cutting the fan holes was very easy with a hole saw. I had a 4-1/4" hole saw and it worked nicely on a large 1/2" plug in drill. A 4-1/2" might be a perfect fit but I was not going to buy a $30 hole saw for 1/4" extra. The holes were surprisingly clean, just a little clean up with a drum sander on a drill. Thanks for the awesome content James!
The perfect tool are industrial electrician manual knockout dies. For the individual who needs the best in every tool, Milwaukee makes an battery operated knockout tool too!
I'm not sure if you will see this. Buy a flex shaft for your Dremel so that your not cutting at such an angle. If you bind those wheels you will get that tear through often. Thanks for all of your videos!
Thanks for the detailed videos and I have borrowed lots of ideas from this series for my VFD for the lathe. One thing I have done is I have used both NO and NC switches in my Emergency Stop. one wired to operate the contactor while the other is connected to the Emergency Stop of the VFD (had to program one input of the VFD as ES). In that way, power is disconnected from the motor immediately by VFD, otherwise, the motor can run a few seconds from the stored power in smoothing capacitors in the VFD.
Very creative way to wire the wall-wart. I've used DIN-mounted plugs, and then plugged-in wall-warts, but that plugs take up a lot of space. I like your solution a lot!
I’m so happy you made a series of videos.....just purchased a G0602 and was afraid of attempting to convert to variable speed due to limited info. These step by step videos are Grade A+.......I will now start ordering all the parts needed to carbon copy your design! The VFD programming/tuning that you did is Awesome for people who are not familiar with electronics! THANK YOU SO MUCH FOR THE SERIES OF VIDEOS!
You sir have created the most informative video I have watched. I'm in the process of replacing the VFD on my Jet 1642 and your knowledge, excellent narrative and highest quality audio/video has improved my confidence 100%. I "think" that's a good thing, time will tell. Thank you so much for your effort and skill in producing this video.
Just an FYI, the glands you used for the cables, at least with the factory compression rubbers, are waterproof. I used to use them for marine electrical wiring for things like solar panel cabling. They saw some pretty extreme conditions and I never had any callbacks for leaks.
Thank you for sharing, absolutely without a doubt excellent work and video. I just finish my 2x72 using the same VFD, and now you have giving me the rest of my future work to enclose the VFD and elements to protect my investment. Congratulations on your weight-lost, I am sure you and your family fill better zzzzzz!!, I should take that tip also, but for that I have excuses, ☺☺☺☺. Thank you and have a very nice day.
On the enclosure, if you had offset the exhaust hole to the left, then you would have had room to cut a opening over the display of the VFD, a little plexi/lexan and you have full view of the VFD display John
My only regret in this stage of the build is the cheap little power transformer & your means of securing it. Given what you had, you did good! I'd have been days either coming up with a proper power supply (more room needed in the box) or at least building a decent mount. You did what was needed to move forward! I struggle with that.
A much better solution would be a power supply mounted on the DIN rail, right next to the contractor (there are plenty of small ones available) or a DIN mounted socket to plug the supply into instead
Thanks so much for all the effort you put into your video series. I've watched each of your videos in this series several times. They're such a wealth of information. Your build is so elegant and well thought out. I am restoring a 1960 Clausing 16VT that has a 3-ph motor and found this series because I am using the same Teco VFD to run it. I'm borrowing many of your ideas for the control box and will use your links to purchase some of the parts. Thanks!!
I’ve been watching a lot of your videos. I’m thinking of installing a VFD on my Atlas lathe but I want to set up the lathe with remote start stop and a emergency stop with a brake.
If you want some even stronger holding tape, try 3m's VHB (very high bond) tape. They use that inconstruction for metal building panels. It's main use is for metal but it also works great on other materials as well.
can you make a complete list of cables size, cable glands, magnetic contactor? I have everything on all the videos and im wanting to rewire everything to be cleaner and more organized. Also what is the adapter that your using to power the fans?
I recommend using a KO punch set for making your cord connector holes. It will make much less of a mess than using a step bit. You will need to drill a 1/2” hole to start, but it’s just better. Less jagged edges using a punch set.
We always used a 7/16" drill for the 3/8" stud. Gives you just enough for bent slug easy removal. Had know it all prima donna maechanics only use a 3/8" drill bit then break their balls and screw up threads on stud banging off slug. I also use a USA carbide 7/8" hole saw for cord connectors. Never install fan exhaust on top of any enclosure unless you install a deflection oversized plate several inches above. Saw water oil etc get into a top exhaust burning up devices. You should use the proper size ampere fuses on all drive inputs. Had a stupid hard head cheif electrician use time delay fuses instead of the quick blow fuses called for. After burning out thousands of dollars in drkve boards he started using the proper fuses.
James, thank oyu for another great entertaining video. Love your work, but as feedback the wiring going to the Plug Pack is questionable, should have more slack in it so it sits down on the bottom, rather than suspended and importantly the voltage rating of the cable used to power it is well possibly inadequate. it is mains cable and should be heavily sheathed, regardless of the current, the mechanical isolation of the insulation counts. Again very entertaining.
Apreciate your videos. I'm in the early stages of a vfd on my wood lathe, but I am unsure about your implementation of the latching contactor, could you provide some more info on that? I understand the wiring on the lathe but I see wires on the uninstalled contactor and I can't see how they are wired. I am using a 220volt vfd which provides a further complication.
Really appreciate the detail even to the extent of drilling the holes and mounting components . What is the purpose of the contactor vs connecting directly to line filter? Fantastic work, presentation skills, teaching ability and passion to do the best you can!
It is generally recommended to prevent the unexpected restore of power to a moving system after a power failure, If it wasn't there, and the power went off, the VFD would immediately turn on when power was restored, which is generally not safe for the VFD and maybe for users of equipment run by it.
I have a die grinder from tractor supply that would be perfect for cutting the fan openings. If you want a better alternative to a dremel you can google die grinder kit and there should be one for about $10 with some 3in cutoff wheels. Unfortunately die grinders are air powered so you will need a decent compressor.
Hi James. Really like your VFD 110v to 3 phase convert. I replaced my old Craftsman 12 inch with my "New 2 Me" Standard Modern 13 inch. Much heavier more precise. Anyway, got a 2 HP motor and Huanyang 1.5kw VFD. Bench tested, per your sugesstion (good idea) all well and installed. Problem I cannot figure out how to wire the magnetic conductor. it is basically like yours. Please show the wiring diagram so I can finish my project. Thanks in advance. JB
Can you tell me about the Contactor? I’ve watched all your VFD video’s and didn’t noticed where you talk about what it does, part number, or anything like that. Wiring mine on a drill press and would like to do it right.
Seems like the proper blade in a jig-saw would have been easier than the Dremel approach. Even so, file cleanup would probably still be appropriate. Still, good stuff explained well. Really like the content and production quality. Anxious to see the completion of the Electronic Lead Screw project. (Ahh, the gift of prophecy.)
When trying to buy the leeson motor, I was redirected to its updated replacement. 1hp marathon… but, it’s inverter rating is non compatible. I went back to the leeson spec sheet. It’s inverter ready. Is this an issue? This series is awesome, along with the ELS. But it’s a firehose of info lol.
Hey great VFD videos!! But I was wondering if you could provide a little more detail on where exactly the start/stop wires go on the contactor and the neutral jumpers you were talking about? Also would the wiring setup u used for the start/stops switches be the same on a 3phase contactor? I wanted to used a 3phase contactor but it will only get 220v single phase power?
Ok James, so we have to cooling fans. I understand that you cannot power the 12v fan with 110, so this is why the power supply is there. If the line filter is lowering the power supply & the power supply powers the fan, what connection let's the VFD tell it to turn on? You mentioned the RA and the COM connection, but how is that connected? Also, what turns the case fan on and off? I've watched the video(s) numerous times, but that part is pretty vauge.
Same....I also noticed you intended to use the Ra line to power the fan in video #1 - that would turn the fans on with the vfd...not sure why the change in approach to fan power??? I’m trying to power an old South Bend lathe with mine and working through this issue now.
@@maalberico The 110v does send power to the 12v motors(+), the plug itself ramps down/converts to 12v. The VFD sends a signal via ground to turn the fan on. If your looking for answers directly from these videos, there will be holes...been there done that. Good luck, I'd be happy to share what I've learned from this mod...
to awesome. what an awesome way to use two color print. brilliant....good lord this a really nice planned out box...i learn so much from yer videos...ill hopefully be starting my els conversion soon..in the middle of building a 5x5 cnc plasma cutter :) videos to come.
Can't quite see where you are attaching the wires to the contactor i.e. to which points are the L and N incoming neutral attached and where are jumpers attached? There a link to photos of these details? Thks.
I see that you used a fairly high quality IP20 rated VFD to drive your lathe motor. We're presently in the planning stages of using a VFD to drive a 3-phase belt grinder motor for our small shop. As this machine will be used year round, the VFD will be exposed to quite a bit of fine metallic dust -- especially during our cold weather months. What are your thoughts on using an IP20/NEMA 1 rated VFD inside of a sealed (NEMA 4X) enclosure to keep the dust to a minimum? Do you think that we'll have to fabricate dust filters that work in conjunction with the fans? I've both liked and subscribed, so please keep on making the informative videos. 👍
@@Clough42 The price of fully-sealed VFDs is what brought me here, Clough. Do you think that an IP20 rated VFD will actually overheat in an enclosed box? Quite honestly, I really don't see us using the belt grinder for more than a few minutes at a time.
I'm not an expert, so you might want to trust the manual over me. :) The manual says that the fuses are to protect the "peripheral equipment" (a.k.a. the motor) in a short-circuit event. I think the breaker will protect the building wiring, and I expect that the VFD will be toast no matter what, so I didn't bother. There are discussions in various forums about whether the fuses are needed. The TL;DR is that fuses were used for UL testing for various regulatory reasons, so they're specified in the manual. All of that said, I don't think you can go wrong with more protection. I might go back and add fuses to my installation.
Hi, You have a great series of videos, informative, well paced and superbly presented. I notice you are using a small, hand held, deburring tool - see 20'54" - to clean up small holes. I've never seen one, I'd like to buy or make one, could you please give me a link to a supplier or a picture of it? Regards Paul in NZ
James, you have some of the best videos out there. Thanks for the time and energy you put into them. I plan to add VFD to my G602. I had one question on this video. Can you tell me what contactor you used inside the enclosure box? Thanks!
James, since the fan in the bottom of the NEMA enclosure is pushing air into the box to keep a positive pressure, why is the fan filter on the outlet? Shouldn't it be on the inlet (bottom opening) to filter the air before it goes into the box?
I think I missed something. Here in canada we have two hots 120v to feed 220v appliances/machines. Is it different in the states? You have 1 line and 1 neutral as though it was single pole 110v. Where did I go wrong?
I used the contactor that came in the lathe from the factory. The contractor is recommended in the VFD manual because it provides a way to disconnect power from the VFD when the tool is not in use.
Will the noise filter you show here do split phase 240v? My motor on my lathe is 3 phase and im using a vfd from 240v split phase to 3 phase. If so, i assume i just wire l2 where “N’ appears on the filter?
James, have very old 3 ph double shaper 5 hp motors. will vfd work on motor not rated for vfd as your Lesson motor? Vfd supplier said I needed to double the hp to size the vfd or 10 hp vfd.
An inverter duty motor has insulation designed to withstand the high voltage spikes generated by a VFD and is designed to run at lower speeds without overheating. I don't see how using a bigger VFD would help with that, but I'm not an expert by any means.
Then you'd make negative pressure inside the box, so dust and moisture would constantly infiltrate (unless you devised a method to seal all around the door and cable glands). James's way keeps the inside of the box pressurized and clean.
you tapped the 120v for the 12V adapter between the output of the contactor and input of the filter? How is the 12v adapter getting power when the contactor is off? Shouldn't it be tapped before the contactor, for a constant source of 120?
I get the heavy power wiring from a local electrical supply (Grover's). Loose conductors are usually just taken from left-over scraps of the power cables. I get the crimp connectors from a local home store (Lowes, Home Depot). My favorite place right now for metric screws is a local Ace Hardware that has a huge selection. Otherwise, it's all available on eBay in small quantities or from McMaster-Carr if you want larger quantities to stock. Depending where you live, imperial screws of similar sizes might be easier to get at a home store.
I noticed that you skipped past the part where you certainly struggled to remove the backing film off of the 3M tape. 🤣 The tape is great, but getting that film off of it is a bitch.
Rationally I know that 3M tape is going to work, but the lizard part of my brain keeps whispering "didn't you learn from all those cable tie pads with the double sided foam tape? The ones that all pulled away due to heat and vibration?" About the only use of adhesives my lizard brain doesn't squawk over is threaded fasteners. I know, it's a problem. I'm slowly working out my trust issues with glue in the context of machinery...
Yeah...tape can be iffy--especially over the long haul. I didn't want to drill more holes and make more chips, since I already had everything else mounted already before I thought about it. Usually when I'm building something like this, I 3D-print a tray that I can screw to the box and then zip-tie the device to the tray. If this one falls, though, it's all insulated, so I don't think it will hurt anything.
I'd trust real 3M tape, especially the expensive stuff over most small diameter made from the chintziest chinesium screws. Surface prep is always the key, but in a new box with quality paint, I can't see it ever being an issue.
This series is the most professionally done I've seen yet, hands down!
I am getting ready to build a vfd enclosure for my setup. I have two vfd's, one for the drive motor and one for the coolant pump on my lathe. I am recently retired, and where I worked. we had a lot of equipment and control cabinets. I modified our cabinets and equipped them with easily removable filter media. The filters (stainless steel media and cleanable) slid in and out easily in the frame of the filter. Easy peasy. It made it so much easier to keep maintenance on the filters. My shop also substitutes as wood working and does that generate a lot of dust, even with the dust collection system.

What are your thoughts on using an IP20/NEMA 1 rated VFD inside of a sealed (NEMA 4X) enclosure to keep the dust to a minimum? Do you think that we'll have to fabricate dust filters that work in conjunction with the fans? I've both liked and subscribed, so please keep on making the informative videos. 👍
For a belt grinder, many people prefer to use a fully-sealed VFD like the KBAC-27D. It's also super simple, with a switch and a speed control knob.
@@Clough42 The price of fully-sealed VFDs is what brought me here, Clough. Do you think that an IP20 rated VFD will actually overheat in an enclosed box? Quite honestly, I really don't see us using the belt grinder for more than a few minutes at a time.
@@timberwrightsvs480 I don't have any experience with that, so I don't know.
I'm really floored by the quality of these videos! I guess I'm getting in from the ground level... haha! Nice work
Sorry to ask. Do you use the filter in the exhaust fan to filter particles when the unit is off?
Nice job. I have one of these drives I'm getting ready to install, and the manual calls for fuses on the input. Why did you decide to forgo them?
I'm not an expert, so you might want to trust the manual over me. :) The manual says that the fuses are to protect the "peripheral equipment" (a.k.a. the motor) in a short-circuit event. I think the breaker will protect the building wiring, and I expect that the VFD will be toast no matter what, so I didn't bother. There are discussions in various forums about whether the fuses are needed. The TL;DR is that fuses were used for UL testing for various regulatory reasons, so they're specified in the manual. All of that said, I don't think you can go wrong with more protection. I might go back and add fuses to my installation.
Is the noise suppressor necessary if there is nothing to interfere with?
Possibly missing washer on dremel for your cut of wheels. I had same problem.
Incredible videos
Hi, You have a great series of videos, informative, well paced and superbly presented.
I notice you are using a small, hand held, deburring tool - see 20'54" - to clean up small holes.
I've never seen one, I'd like to buy or make one, could you please give me a link to a supplier or a picture of it?
Regards Paul in NZ
Hi Paul, a quick google search yielded me this. www.artcotools.com/roto-drive.html
Maybe that can get you started?
James, you have some of the best videos out there. Thanks for the time and energy you put into them. I plan to add VFD to my G602. I had one question on this video. Can you tell me what contactor you used inside the enclosure box? Thanks!
He kept the factory contractor from the G0602 motor electrical cabinet (around back) view previous videos
@@makealready Thanks Jacob. I saw that when I went back and looked at the videos again.
Awesome VFD series... Could you please explain me, how did you wire the contactor for a single phase input?
I showed the contactor wiring in the VFD Controls video: th-cam.com/video/J_IojFauSGs/w-d-xo.html
Where do you purchase the exhaust fan and filter ?
Another great Video
Did you leave the filter in the outlet 'frame' of the Hammond Enclosure?
Yup. To prevent grit from coming in the exit.
What brand/model is your automatic center punch?
Good idea to do, but why you using a contactor in the system if you using a 3 phase motor with a VFD?
So he can use the contactor to shut off the VFD while keeping main power to lathe on
James, since the fan in the bottom of the NEMA enclosure is pushing air into the box to keep a positive pressure, why is the fan filter on the outlet? Shouldn't it be on the inlet (bottom opening) to filter the air before it goes into the box?
Yes. I think they both might have had filters on them?
whats the contactor for and do u run the single phase power through that to the vfd
I think I missed something. Here in canada we have two hots 120v to feed 220v appliances/machines. Is it different in the states? You have 1 line and 1 neutral as though it was single pole 110v. Where did I go wrong?
This is a 110v VFD.
@@Clough42 There ya go, i even watched the entire series and just assumed it was 220. My bad. Great series btw.
which contactor did you use please, and why did you have to use it when you could have used the digital inputs on the VFD?
I used the contactor that came in the lathe from the factory. The contractor is recommended in the VFD manual because it provides a way to disconnect power from the VFD when the tool is not in use.
Will the noise filter you show here do split phase 240v? My motor on my lathe is 3 phase and im using a vfd from 240v split phase to 3 phase. If so, i assume i just wire l2 where “N’ appears on the filter?
Split phase? Just 240 single phase? If so yes.
super awesome video
James, have very old 3 ph double shaper 5 hp motors. will vfd work on motor not rated for vfd as your Lesson motor? Vfd supplier said I needed to double the hp to size the vfd or 10 hp vfd.
An inverter duty motor has insulation designed to withstand the high voltage spikes generated by a VFD and is designed to run at lower speeds without overheating. I don't see how using a bigger VFD would help with that, but I'm not an expert by any means.
It just depends how hard you are going to work it and can you keep the motor cool. Low frequency/low rpm makes the motor heat up.
What are you using the contactor for? Is it acting just like a disconnect
Yes, that is all it’s for.
I would have put the fan in reverse to suck air out. That way you only need a filter on the inlet on the door of the enclosure.
Then you'd make negative pressure inside the box, so dust and moisture would constantly infiltrate (unless you devised a method to seal all around the door and cable glands). James's way keeps the inside of the box pressurized and clean.
Great videos! Can you please tell me the values of the magnetic contactor that you used? Thanks for taking the time to share your knowledge.
Thank you! I reused the contactor that was originally in the lathe for the stock controls. It's a Siemens 3TB41 22E 110V.
Perfect
James, that doesn’t look like an M4 tap.
What pocket knife did you use to cut the tape?
That's my EDC. I believe it's a Benchmade 812 ATS-34 Balisong.
Question in an enclosure how to run a DC fan with the VFD. OR do i need 110 vac for a fan.
HELP please
I usually use a 12V or 24V fan running off a separate power supply.
@@Clough42the way you comment i will need a separate 110 vac outlet to power the dc verter
Curious why you didn’t just use a DIN rail power supply instead of the hack one?
It's what I had, and at the time I made this video, I hadn't yet developed my fetish for DIN-rail mounted devices.
@@Clough42 glad I’m not the only one! 😂
you tapped the 120v for the 12V adapter between the output of the contactor and input of the filter? How is the 12v adapter getting power when the contactor is off? Shouldn't it be tapped before the contactor, for a constant source of 120?
The 12V power is used only for cooling fans, so it's off when the contactor is off.
I see. Guess I missed that. what's the coil voltage on your contactor? where is it tapped? @@Clough42
@@johns208 It's wired up to the AC input side of the contactor. The video showing the control wiring has a diagram.
Wasn't/isn't it necessary to have a ground from the contactor to the box star ground?
No, there is no ground for that contactor the Din rail is grounded to the box. There needs to be a transorb wired in with the coil wires though.
10:04... she purrs like a kitten...
James where do you get all the wires, screws, etc, I'm new to this but need a little help with the parts?
I get the heavy power wiring from a local electrical supply (Grover's). Loose conductors are usually just taken from left-over scraps of the power cables. I get the crimp connectors from a local home store (Lowes, Home Depot). My favorite place right now for metric screws is a local Ace Hardware that has a huge selection. Otherwise, it's all available on eBay in small quantities or from McMaster-Carr if you want larger quantities to stock. Depending where you live, imperial screws of similar sizes might be easier to get at a home store.
If I'm using a 3hp spindle will I need a contactor?
Just depends if you want to be able to turn the VFD off without turning the whole machine off. That is it’s only function
Nice !!!
Can anyone answer where and what kind of magnetic contactor ?
Funny, I am looking for the exact same thing myself. If I find info I will post it.
Dave Nichols I found one at work my electrician showed me, now I’m trying to find one online .
Hole saw for fans
Most manufactures don't recommend a contactor be used.
Why not? Definitely not on the output side but a contactor on the input can be used for many different functions.
the fan large holes use your cnc machine
just watched it for straight 33 minutes.
tidy job sir
Thank you.
Ugh, just get a small utility DC supply for the box instead of jerry rigging a wall wart.
Just use a 120v fan
no link for the contactor
I reused the contactor that was in the lathe.
It’s just a 3 phase contactor with 120v coil.
I noticed that you skipped past the part where you certainly struggled to remove the backing film off of the 3M tape. 🤣 The tape is great, but getting that film off of it is a bitch.
The rare moment when it comes off easily is to be cherished.
Rationally I know that 3M tape is going to work, but the lizard part of my brain keeps whispering "didn't you learn from all those cable tie pads with the double sided foam tape? The ones that all pulled away due to heat and vibration?"
About the only use of adhesives my lizard brain doesn't squawk over is threaded fasteners. I know, it's a problem. I'm slowly working out my trust issues with glue in the context of machinery...
Yeah...tape can be iffy--especially over the long haul. I didn't want to drill more holes and make more chips, since I already had everything else mounted already before I thought about it. Usually when I'm building something like this, I 3D-print a tray that I can screw to the box and then zip-tie the device to the tray.
If this one falls, though, it's all insulated, so I don't think it will hurt anything.
I'd trust real 3M tape, especially the expensive stuff over most small diameter made from the chintziest chinesium screws. Surface prep is always the key, but in a new box with quality paint, I can't see it ever being an issue.
