For the person just learning. Needing a grasp to understand. This guy is it. He is far more advanced than the learning person needs. Yet talks to us like we are people. So humble. He is why KZfaq was invented. To teach and help. Very smart man. Love the videos.

I’m a Journeyman Electrician and I’ve got to say watching your videos has taught me more than any class I ever took. Your videos are so informative yet so interesting. Awesome content.

wish i had met someone like you when i was younger, I tried to understand this stuff over the years, and now at 70 yrs old I am starting to understand it when you explain it. You are so cool. thanks.

Jeremy, you are a perfect example of the American pride of excellence through independent investigation. Revealing one's own potential through learning and then giving it on to others by teaching is you by example. I love this channel. 72 years old and still learning here. And you - I would like to meet you someday - are the teacher I wish I had had when I was 12 years old! Thanks for your fine example and your channel content. Impressed I am!

I rarely comment on any how-to video, but I felt compelled to tell you what a great job you do with these. I have watched several, and the quality is consistently very high. You have the ability to convey complex ideas in a very straightforward way. Thank you.

Jeremy, I've been watching your vids for some time, and you just keep getting better and better. Reckon you would have made a great science and tech teacher. Many thanks.

Thanks for this explanation on how you can do this, I’d always heard “ it can’t be done “ but you proved it can be done. Thanks again !!

Love your channel. I'm a machinist and I've really been interested in building my own shop. Give everything character. It's nice to see a video of someone I can understand. Learned a lot watching. Much appreciated.

This is a lot of information. Good to see you show the "not so good" options along with good options.

you are by far the best teacher of this electrical stuff ever. been trying to grasp this stuff for years. your giant 3 phase brain is able to convert this knowledge into little spoonfuls of single phase knowledge which my muddy brain actually comprehends. thank you sir and kindest regards from Massachusetts!! 🇺🇸

So happy I came across your channel man so very informative you don’t just GIVE out answers either you need to think a bit which makes the viewer that much smarter. I’ve been binging your motor and wiring videos and can’t thank you enough for taking the time to explain and share your passion and knowledge with others. And if it means anything else very proud to see you include your entire family and include them in the learning and projects. Thank you again. Jeff, Chicago IL

Great work! I love the effort and time you put into this. The fact that you covered such a multifaceted concept in so many different ways, in a DIY project, is incredible. Taking the time to share it all afterwards is just above and beyond. Thank you!

I don't think I have ever seen a better video than this one on KZfaq or even elsewhere. Thank you very much for this helpful topic, and thank god for providing a knowledge angel as you!

I love these motor videos. I'm making a big collection of my own. In fact, I got a 10 amp vacuum motor today. Epic stuff Jeremy.

you Sir are the MR Rogers of electrical engineering, people can learn a lot from your vids!

Very cool. I've watched "HUNDREDS" of videos on this subject, and founds yours the most informative and easy to follow. I will definitely stay tuned. Thanks alot.

Great video, I've been waiting for a video like this for a while.. thank you for taking the time to post it . 👍👌🏽

Just recently discovered your channel and am really enjoying your videos. I am a civil engineer, whom was required to take several circuits courses in my program with little practical application. Many years later I have taken up a woodworking hobby and have been performing maintenance on previously owned electrical motors. I share a similar you enthusiasm for the centrifugal start cap switch, its brilliant in it's simplicity and just goes to show how the simplest solutions are often the best.

Excellent teacher. Clear and concise. Speaks in a language I can understand even though I am not good with electrical work.

Great video Jeremy, very informative, keep up the great work.

I just bought an older Singer industrial sewing machine 281-22 that came with a 3 phase motor. Most people who own these go with the 110v servo motor to run them. I decided it was a good time to learn how to convert single phase to 3 phase then get the 110v servo later if needed. I really enjoyed your video and appreciate your help with all I learned from you. I am going to keep an eye out for more of your videos. Thank you from Bremerton Washington

⚒🛠🔧⚙️Super informative, glad to be part of your cobbling for fun network. I really think you’er such a wizard and gifted in your knowledge and presentation, and ability to explain in an entertaining and informative way. Thanks for the effort, hard work and personal time invested, its a true valued service you provide. 🍺🍺🍺🍺🍺

Sir you are by far one of the BEST teachers with such clarity as a simple minded person such as myself can and does understand. You have helped me more than you will ever know. Do not stop sharing your knowledge, please! God Bless

Another fine video. I put a 3 phase motor and VFD on my lathe to gain variable speed. It's worked out ok for me. I appreciate you teaching me a bit more on how it all works.

Automatic "Thumbs up" before I started watching... You are Awesome Sir! THANKS!

Your a natural educator! I wish I would have been able to see these videos while in college. Makes a lot more sense now!!

I have found your videos better than instructional sessions I had in college on these subjects, when studying for my electromechanical degree. Truly superior.

Great video, Jeremy! I'm an electrical engineer, and love tinkering with things just like this. I have a 3-ph motor I have been meaning to integrate into my shop, and you've motivated me to get started. I might add that one source of potential relays is [probably older] salvaged HVAC units.

As always, a wonderful video. I've done a lot of my own electrical work in my business and in my personal shop. I am now reviewing what I've learned because I am moving from the US to Sweden and I am learning how to transfer all of my US knowledge to the Swedish system. What is very interesting about Sweden is that they have 3 phase, 50 hertz power to nearly every home, farm and industrial site. The only exceptions are to some of the very old, remote houses that were farms that were electrified in the day when electricity was only used for light bulbs so that you could save on the use of candles in the winter. Your videos are a great help in coming up with modifications and workarounds to getting my shop in Sweden into functional shape. Again thanks for your great work. Having 3 phase nearly everywhere in Sweden makes it very nice for wiring a building because the wire gauge is so small relative to what we have in the US. My biggest problem is having 50 years worth of high quality electrical tools that I want to take to Sweden with me. I would get a dime on the dollar for my tools if I sold them here and then bought everything new in Sweden. I am coming up with creative ways to create 120 volt, 60 hz power in Sweden and running separate circuits to run my small tools on throughout the shop. On all of my large equipment I am simply going to sell the 60 hz motors here and repower with the equivalent 3 phase motors there. There is a really good electric motor shop in the small city near me that is willing to work with me on my repower needs. I am finding that there is an abundance of inexpensive 3 phase motors in Sweden. Also, my few pieces of 3 phase, 60 hz equipment can be run on the Swedisn 3 phase, 50 hz power understanding that they may run a bit slower or have less power.

What a brilliant video. Someone who actually openly shares knowledge. Thank you for sharing.

Great video! I love the way you communicate, you maintain a steady level of expertise not usually found in videos on this subject. Where others are let their experience and knowledge creep in then drift off into lingo unfamiliar to the layman or are so uneducated on the subject they seem as confused as the viewer, you remain steady and ealisy understandable for the person with at least some basic knowledge.

Jeremy, great video. Over 30 years ago, a very talented mechanical guy, showed me a way to run two 3-phase motors from single phase without capacitors, just the wiring and a short piece of rope. About 15 years ago I passed this information to several electrical apprentices in our factory, and added a problem for them. Design a PLC program to replace the rope. What fun!! (For me, not so much for them).

Well done. I learned a lot; and, I especially appreciate your attention to safety.

Jerremy, I would like to suggest a fourth method. You can start a three phase motor on 220/240. Wire up two legs and then literally pull start the motor like you would a lawn mower. It does not have the full horsepower but I have seen it work. Once the first one is started you can then run other motors and start them like you would with the pony motor. I don't know if it heated up as much as the run capacitor method and you obviously need a way to disconnect the load but it will work. I was told that with multiple ones around the shop the person who did it was eventually able to basically run each one on just a single phase input since he had some sort of a switch in place to switch the second phase from the line to a third pony motor. Honestly using a capacitor start method you should also be able to momentarily use a cap to start and then remove the cap and keep the other phases connected and keep it running with those phases balanced and the third generating. The person also told me that he was able to actually fool the power meter into spinning backwards with his single phase input method... I don't know if it was true or not but the power company came out to his place as per his story due to discrepancies and pulled the meter with things running to see if he had splice power in before the meter and was stealing electricity. The story went on that it all died when the meter was pulled and so the assumption was that the meter was being spun backwards because it was not able to read things correctly due to the noise the motor systems were backfeeding into the meter. He said he would leave everything running for weeks on end. They said they could put in a different meter that would be able to catch it but that the power companies cost to do so would be so large it would end up being a huge loss for them to do so vs his ability to just shave his bill down to 50 bucks a month vs 100. Again I can not say this is true or not but I saw with my own eyes a three phase motor start and run with the pull start method.

Great job, Jeremy! I get a lot from your videos. Thank you so much!

Ive been trying to get into this for a while.....watched loads of other vids.....but this series has been brilliant...thanks loads!!

I had a similar situation a couple years ago. Went thru all you have so very well described here. My problem involved a 3 ph 480 vfd that I wanted to run on 240 1ph I had to purchase a voltage rated vfd to complete my project. You sorted it much quicker than I did. You are very well spoken in electrical knowledge.

Best description of all the options I’ve ever seen. I’ll definitely be checking out your other videos.

You sir are a gentleman and an electrical scholar. Thank you for your videos, they are greatly appreciated!

I built a rotary phase converter for my shop 15 years ago still works great this is really good information sir

Awesome vid. I will definitely be watching more and getting caught up on the topics you already covered. Thanks for the knowledge and have fun Tinkering..

I don't know you and I have never met you but your humility oozes from just your speech. And they say, "Intelligence breeds humility".

Thank-you. That was one of the best videos on this topic I've seen.

Great video, really clear and informative. Wish I had seen this months ago !

There are not very many dedicated and well-experienced yet practical teachers like you. I loved every sec of this video. Well explained, demonstrated, and excellent commentary with great tips and knowledge. I liked your video and subscribed to your channel. Thank you for sharing your knowledge.

Your a genius at your skills. No one was ever able to explain the capacitors providing a extra phase like you did. Im an electrician and have maintained a 3 phase motor running on single phase through capacitors providing the 3rd phase. The motor amps were never balanced with a load. The motor held out fine for many years. This was way before variable frequency drives were available and small enough to power small pumps. Thank you . You are very entertaining and knowledgeable.

I love your content. I also love seeing you with some of the other teachers out there on KZfaq. Great work!

My new favourite channel. thanks for providing this Jeremy.

Dude. You are the best. Your fanboying over that potential relay cracked me up. Thank you.

nice stuff, smart teacher , good way to teaching ,very clear and accurate , no body is better than you here on KZfaq ,you are the men, i know because this was my job before

Love your videos. So informative and you always find the topics we are looking for

Always remember when working with a VFD that it has a capacitor bank that stores a DC charge and could take a few minutes to drain down to safe levels after removing power. Check the DC terminals for voltage before touching the terminals or opening the drive. Thanks for the video Jeremy, I am a VFD repair tech guy. Love your videos.

Bing your videos. You're a great teacher. So easy to listen to and understand no matter the listeners knowledge level

This is good to know info! I'll have to keep this video handy! Thanks for posting this

Thank you Jeremy, I learned something new today.

Hey thanks so much for posting such a comprehensive video explaining these things! It is by far the best I have seen. I have an old 35mm projector attached to a lamp console that each run on 220v 3 phase. I’m probably going to scrap the lamp house because it is too impractical and would consume massive amounts of energy. I definitely either wanted to either reconfigure (not an option) or replace the motor but they are hard to find. I’m on the prowl for a VFD now. Thanks again for the post!!

Thank you for your videos! I've learned so much from them. Easy to follow and not full of unneeded info to confuse. Keep up the good work...

Brilliant teacher, explaining in an easy to understand way. This video has helped me, so I thank you for sharing your knowledge.

i will highly recommend this channel to all my friends that tinker with motors and tools. You, sir are a master, bravo!

Great explanation. I have always wondered how to run a 3ph from single without a converter or VFD. Thanks for showing us how to tinker in this video as well as your many others. You are a great educator, thank you for what you do.

Jeremy, I've watched multiple videos of yours now. They are great, you are great, this is all great. Honestly thanks for helping get good information out to the people. Repurpose, reuse, recycle!! 🤑

Thanks for all the effort man, was a great series with lots of useful information.although i knew how to do identify, wire and control all these motors, i couldn't resist watching these cause i knew i'm gonna learn good stuff from your experience.it worth a lot to me and i very appreciate what you do.just one more thing, please be more careful handling electricity. thank you

Thanks for the info jeremy. That helpes mw alot with my problems..

What a lucid description of 3-Phase motors. Well done.

Very nice video,thanks for taking the time to explain the solutions in great detail.

Great Video! The way you explained the starting relay was perfect.

Just klick on the bell!! You have earned my respect sir!! Definitely Simple Enough. Yet to the point! Thank you very much...

This was very helpful. I was trying to figure out how to get power to a 3 phase plasma cutter, and a VFD is definitely what that would need. Thanks!

Really great series of videos on motor control. I have copied the first and second option and very happy. Thanks Jeremy

Wow ..very educational .. learned more watching this video then I have in 32 years of hands on Thanks!

I had no other choice but to sign-in to like and subscribed because your explanation is just OUTSTANDING especially considering the content you cover. I would literally like your videos a thousand time if I could ... :D

Thanks for the great vid. Very informative and keeps me from loosing my mind in isolation.

I like your soomed picture bubble with detales of the rating plate on the engine, or electrical component you are introducing. Fantastic job with editing the video, and keep doing that. 👌🏼😇👍🏼

Hi Jeremy, Great information, I've not had done the caps before. I have however used a VFD before, just simple enough to run a milling machine for friend.👍

Very well done and super informative. Thanks for sharing.

Just found your videos! Thank you for these helpful instructions.

@Jeremy Fielding Jeremy,. As I read the first 10 or so comments, I'm amazed at how much your subscribers enjoy your videos and take the time to give you props and good energy... The LEAST YOU could do is take a few seconds to say, THANK YOU. Also,. You're making a VERY COMFORTABLE living$$ doing this work.. Hire someone to respond to subscribers, after all, it's us that are forced to listen to all your sponsor ads, etc. Thank you for probably not reading this. Thanks for your knowledge and videos.

He is the gift that keeps giving !!

Jeremy: Great Vid as usual, another "cheap" option not covered is to use a 110V motor to spin up a 220 3 phase pony motor and then turn the 220 on the spinning motor. Output for third leg is created (cleaned up with Capacitor if desired) and the 110V motor is turned off...the 220 3 phase is then running on 220 1phase, creating a third leg for another motor in the shop. I've used one like this without a 110V starting motor by rolling the pulley on the 5hp 220 3ph motor over with my foot, then hitting 220 single ph power, it runs my 2.5hp 3ph mill motor. Risk is if power went out while using I may forget to kill the system, so I should add a Magnetic switch to the start switch which would turn itself off if the grid power died. Building a larger 20hp3PH I will drive off a 110 belt pulley for start as I have a 7hp Cincinnati mill I picked up. Great Vids, keep it up.

Many thanks for effort and easy explanation for completed subjects.. Thank you from Oman.

Thanks for the video!! Now I have an understanding how a rotary phase converter works! Never thought to use a VFD for 3 phase. Nice!!!!

Great video. (You do have really good bedside manner for this!). I'm with you on the VFDs, 100%. Everything else is kind of a kluge by comparison, and in a lab setting (or potentially a shop), having a legit 3 phase adapter like a VFD, with all the accessory features they typically provide, seems wise if not essential. Speed control, current limiting, brake features, current displays, voltage adjustability... they are the bomb. I have two 3-phase VFDs and 2 single phase VFDs (they do make them.)

Great job, Mr. Fielding! Thanks!

Hello Jeremy, I enjoy watching your videos and really I'm not very knowledgeable about electricity but having said that I worked at a small shop for a couple of years that had no three phase power and they had been running 3 surface grinders, 3 Bridgeport Milling machines + 2 engine lathes all on 220 volt single phase. There was no phase converter as such but we used a 2 horsepower and then I believe later on a 5 horsepower idler motor which we would bring up the speed with a 110 volt washing machine motor connected with a V belt once The Idler had been brought up to speed we kicked off the v-belt and shut the 110 volt motor down and we were able to run all of these machines for years. The only problem while using a wattless third leg was when the Mills and lathes were running simultaneously sometimes The Idler would shut down for lack of capacity at which time we stopped running one or two of the machines in order to lighten the load and I suppose a seven and a half or 10 horsepower idler would have helped the problem because I was told that The Idler horsepower needed to equal the total horsepower of all the machines together although the most powerful machine was a 7 and 1/2 horsepower lathe. As I said this situation went on for years until they moved to an area where there was three phase available and we also had no need for variable speed as this was done on the Mills and the lathes by way of gearing and not motor RPM control. Once again Jeremy I really appreciate your videos and as I am past 80 years old they are entertaining and enlightening for me to watch your videos and so I hope you'll forgive me for making a comment about the way you phrase some of your sentences which is very very common today but is redundant and certainly not necessary please take this comment lightheartedly. When you say I'm now going to go ahead and turn on the machine, the words I'm now going to go ahead, are not necessary and in my day you would simply say I'm going to turn the machine on, not I'm going to go ahead and. Keep up the great work, you have a excellent speaking voice and an obvious grasp the subject material that you're are showing in your videos equaling a very smart fellow. Sincerely, your enthusiastic fan.

Thank you for this information you are very knowledgeable , and a great teacher, I will be trying this, I'm a HVAC Tech / Elec , and I do have possession to all of these parts.👍

Great video and excellent information, thank you!!

This is really good stuff. Thank you Jeremy.

Currently building a 2x72 belt grinder from scratch and this has been invaluable. I am good with lots of stuff but electrical things are just usually beyond my scope. I have watched a few of your videos now and the way you explain things using both technical terms and layman language is just incredible. Thank you for your time in putting these types of videos together.

Thanks for the info on VFD's.

buddy if you are not an expert there are no experts, you have the most helpful and applicable videos that i have found so far. great work and thanks for the help.

I so much appreciate all video you put out, i learn so much. Thank you

Thanks for sharing. Lots of good info about motors. Nice video! : )

Thank you for the video ! Years ago I had found someone that told me 15 microfarads per horsepower was good, at least for a test. I ran a 1.5 Marathon 208-240/460 volt 3phase motor on single phase, wired for 208/240 with a 30 mfd capacitor and it ran smooth, ran cool for over an hour, no load of course but it was kinda cool to see it come to life. ... I always wanted a VFD but at the time,. it wasn't an option due to funds. If I end up running into more 3 phase motors, a VFD will be the route I go.

I enjoy your channel. I consider myself a tinker/experimenter. I get this from my dad and he’s why I’m writing. He converted single phase to three phase by using a “dummy” three phase motor in between. He had a 220v single phase panel that he ran three wires from and, the best I remember, connected those wires to the dummy motors’ leads and on to the working three phase motor. Three sets of two connected, each pair separate. In order for this to produce the desired results, he would spin the shaft of the dummy motor by kick starting a pulley that was on the dummy. He did the spinning movement as he turned a separate three phase disconnect to the on position. All this was to power an older industrial metal lathe. There would be times when the lathe would stop working and the starting process would have to be redone. I hope you understand all that took place as it was fascinating for me to see this actually work. Keep up the good videos. Steve

Just found out about your channel from a video Matthias Wandel put out. Really enjoying what you have here and just subscribed. Keep up the great work!

Hello mate. I’m enjoying every post you do. I love the idea of utilising what I have collected in my shed. I’m a full creature when it comes to electrics and often need to relearn it when I need to do something.

Thanks for the video, it was very helpful!

Excellent discussion on a topic that confuses many home shop folks . Thanks .

Your channel is fantastic! GREAT content!

The treadmill motor was a good find!. I love recycling washers and dryers, and printers/copy machines are loaded with good mechanical parts. Another source you might have overlooked are burned out cfl bulbs and burned out GFI receptacles. They each have 5 1n4007 diodes good for 1,000v at 1 amp
