I've looked at a thousand vids on this subject and yours! FINALLY! I get the complete picture! Thank you for this wonderful explanation.
There are so many forums wherepeople argue endlessly about the merits of running a tool at 240 instead of 120. Some people claim that beyond the reduced amperage consumption, wired at 240 the motor will have a higher stall torque and thus will be harder to bog down and run better. I think it would be a great video if you tested these different theories. I have seen lots of talk about this topic but not a lot of proofs lol. Thanks for the great videos, keep it up
This video is incredible. I’m literally watching this at my job. You’re saving the day right now
i know Im randomly asking but does any of you know a method to get back into an Instagram account??
I somehow lost my password. I would appreciate any tricks you can offer me!
@Nixon Elian instablaster :)
@Danny Joseph Thanks so much for your reply. I got to the site thru google and I'm trying it out now.
I see it takes quite some time so I will get back to you later when my account password hopefully is recovered.
I have a jet pump. I'd like to switch to 220. It's not nessarly dual voltage but why can't your switch it anyways?
Just completed a rewire on a Dayton 3/4 hp dual voltage motor from my Dad. Needed to reverse the rotation direction and keep the wiring at 115V. This video gave ALL the information needed. Jeremy, you are a wonderful teacher. Keep up that good work!
Jeremy, you saved my butt! You have definitely earned my subscription! I bought a used motor only to get it home and discover it turned the wrong direction and was "non-reversible". It was also a dual voltage motor, but I did not know why there were six coil wires rather than the four I was expecting, and two of those wires were soldered together! Thanks to your video, all was revealed, and by desoldering the wires that were soldered together I was able to identify the two run coils and the one start coil. I switched around the polarity of the start coil, soldered things up, and put it all back together complete with new bearings. It now spins the direction I need and purrs like a kitten!! Thank-you so, so much! I am currently building a 20 inch bandsaw using plans purchased from Matthias Wandel, and wanted to use this motor to spin up, and test the saw. The motor is 1.5 HP and spins at 3450 rpm. With a 2.5 inch pulley do you think it will spin too fast to be used long term? I can see that you use a 3 phase motor on your saw. I am curious what the power of that motor is, and how many feet per second you run your blade at? Many thanks!
There is a whole video about that project.
I have been wanting to convert my grandpas 1959 Dewalt 925 over to 220 and I never understood what the wiring chart was showing. The way you explained everything I can not only do it but I can understand what i am doing. I was always one of those little kids that said "but why". Thank you so much for telling me why. You are an awesome teacher.
This is by far the most simple explanation about a dual voltage motor which a person with zero knowledge on wiring a 6 lead motor. Thank you so much!! My late dad left us a vintage thomas sprayit compressor. Looks like im gonna try to revive & use it. 👍👍👍
Learn something new each video on this channel. So cool.
I have an 3 Phase Induction motor with dual 230V 460V something like that and wandered how i will wire it for a VFD to DIY build a test bench to spin VE type diesel pump at 600 RMP and 2200RPM the IM is rated at 1400 RMP thereabouts, i'm hoping the VFD will get the RPM up. Australia is 240V standard house 10 amp.
Plus use it to drive a pump to run waste veg oil through centrifuge at 90-100 psi.
All this stuff is way over my head but with your help from the videos i'm learning and getting confident that might be able eventually do it. Thank you so much cool channel. Great minds that surface on the internet now days is amazing.
First good explanation I've ever seen, thank you.
Thank you so much, accidentally ripped the cord out of my motor and couldn't figure out how to wire it, thank you for the education and walk through, you saved me a lot of headache!!!
Thank you to both of the Jeremys! I just rewired my lathe which can with a dual voltage motor for 110!
Thank you for helping me learn about electricity and motors. You are a good teacher.
This is the clearest explanation of this topic I've seen. Thank you!
Your helping many women and men put food on their tables of their families. God bless. Thank you.
Dang! Love it when people take pride in their work. Thank you for educating me with your perfectly crafted video.
Thank you!
This is just what I needed today to wire up a motor I got recently that had no labels. Thank you so much!
Well done. Great explanation without any distracting music or foul language.
Great tutorial! Thanks for taking the time to teach us this info!
This is a channel I would pay a subscription to. This guy is so easy to learn from.... Thanks....
Your explanations are so easy to understand. Love it.
Awesome man! I appreciate your time and knowledge, to inspire us to learn more about mechanical and electrical stuff I love it! I like to play a little bit , but not enough so I’m learning from your videos. I love it I can’t absorb enough information so fast but I will keep watching your videos and thank you so much god bless you and happy merry Christmas 🎄
thank you so much - I got an old 1947 delco 1.5 hp beast - repulsion induction motor with no specs and needed to figure things out - this helped so much. You explained it so well and you are well organized. You put so many of these you tubers to shame on tutorial videos - very awesome
I hope these vidz get you paid mate cos honest, you must be the only guy Ive seen on YT who can actually portray a moderately complex subject in simple terms that people can follow and understand, muchas gracias
I’m about to graduate as an electronics engineer and I just found your videos . The few videos I’ve watched so far I really enjoy learning with you m!
You're the only source for such an in depth info.
Thanks so much for this video. Like others have said, I searched for a video with this info and couldn’t find anything. So glad I found your!
You're a great teacher Jeremy. Thanks for the video's... maybe one day... after watching your video's... I'll have a clue as to how to build myself and/or make/fabricate a rotisserie motor here in the Philippines. I'm totally new at this motor stuff but I learn a little more with every video. Keep up the good work!
+Sam G ... Sorry, Sam... didn't mean to trigger ya. Correction noted...
Many ways to approach that. It is more difficult to get low speed motors.
Synchronous motors from old microwave oven turn tables to the likes of a corded or cordless drill driving a bicycle wheel to get the gearing correct. Obviously larger motors can be used depending on the size of beastly you'll be cooking.
You'd be quite surprised by the torque you would get driving the rim of a bike wheel with a small motor where the gear ratio will be very low at the hub- your spit drive.
A 20" rim driven by a 1/2" pulley on the drill gives you a 40 to 1 ratio in both speed reduction and torque increase (not allowing for friction)
That was a great explanation. I have been working on my boat lift motor for a week. I wish I had found your video sooner. Thanks!!!!
Thanks for making this video. This is a great way to explain it, and saves me a ton of headaches while trying to explain this to a newbie. Great job!!
Awesome video, thank you for posting. It really helped me out wiring an old motor that the label was scratched off of.
First class job. Thanks Jeremy
Jeremy you have a great way of explaining things. It is very understandable.
This is PERFECT, just what I needed. Very clear explanations, well demonstrated, keep up the totally awesome work!
It worked! Dayton 1/3 HP on 110. It came to me without a power cord, and electrical wiring is something I know very little about. Thanks to you, I managed to figure it out and get it wired. Keep up the great work!
As a former HVACR tech this is exactly how we were taught to find which set of terminals was the start winding and run winding on a single phase compressor*. You may know that most refrigeration compressors wired for single phase and under 5 HP (More or less depending on the manufacturer.) have three terminals. The highest resistance value between any two terminals is both the run and start windings as those are connected together and will make a circuit, the next highest is the start winding and the lowest is the run winding. A good reminder of of how to find the correct windings on a single phase compressor. *Refrigeration (Includes Air Conditioning.) compressors are often totally sealed units, they are an electric motor and a compressor combination.

Thanks for another fine video. I hope you have a great holiday and new year.
There are some trade schools that want you. You are a great teacher.
Jeremy, Thank you for the excellent videos you do. Very clear and concise explanations. Well done.
A little tip from the book: Your supply wires (AC cord) should ALWAYS be female plugs, and your receiving device should be male plugs. This prevents you from touching live AC wires.
The resistor analogy & demo was very effective, thanks.
I’ve been looking everywhere for this information, thank u very much sir.
Good description of motor windings. Thanks
Converting the motor on my milling machine from 110 to 220, there is information on the motor but this was an excellent explanation of what you are doing.
This is one of those things that I don’t use often enough to keep at the top of my mind and I really only needed the diagram but you did an excellent job of explaining why there are 6 wires and how they can be configured for dual voltage.
Thanks so much! I searched all over for this info and just couldn't figure it out :/
This is exactly the info I needed.
And thxs so much for taking the extra effort to do the example with the resistors
Neighbors like you are the reason i make videos like this. I was glad to do it.
U did a awesome job showing the right way to learn how to wire a motor? Awesome job..
Excellent presentation and explanation! Thank you!
Great job as a old time retired factory maintenance man your presentation was both spot on and very well demonstrated. I get frustrated with people on the internet comments saying there going to lower there machines 240 instead of 120 to save money please go over billing for kilowatts WVA thanks
I actually talked about that in this video, then I edited it out to make the video shorter. It is a common assumption, but the difference is negligible at best. Certainly not worth rewiring anything.
The difference is in current loss. The more current you put through a wire the more you lose due to resistance to current flow (impedance). At twice the voltage but half of the amperage, losses will be lower for a given length of circuit, but that is generally minimal in a properly sized circuit. The advantage comes with sizing the wiring in the wall and the hookup smaller for lower amp capacity. Cost increases for 240V plugs and sockets vs 120V. I did that calculation as I sized a wall circuit for the saw in my new shop space. Decided to try it on the higher voltage. I wonder if it will run cooler on fewer amps?
thank you for making this video! The series and parallel explanation is a game changer.
Well done, best video I've ever seen on the subject.
So simple. Thank You. Well explained and illustrated. Verbal show and tell. Love the reverse wire explanation to turn the motor backwards ( if needed ).
love your videos and this was just on time, I am building an air compressor out of an old 2 stage Frigidaire compressor and needed my my motor to turn counter clockwise. With your help i had it in 5 minutes 😎
thanks
Great videos!! Love the way you creatively solve issues!
Right On Jeremy. That Was Exactly What I Was Looking For Very Practical. The Example With Resistors Was Awesome.
Fixed mine. It was the thermal switch! Thanks!!!!
This is info that I need right now. Thanks.
Thank you for explaining this, I appreciate it!
Thank you from the future. Your channel has inspired me to continue my adventure into electronics engineering. I know a lot of this but the reality is understanding and knowing is two totally different concepts. You help me move from knowing to understanding.
Said like a Boss! I like that!
This is such a clear well explained video. Thank you!
Thank you a thousand times for all the info your pouring out.
Thanks so much Jeremy!! I have an old motor I need to rewire and I didn't know where to start. You make it look easy : )
Great website Jeremy, I enjoy watching your videos!
Dude ,you are a wonderful teacher.
Wow. You are a very good teacher. Thank you!
Many thanks, I’ve been trying to get into a maintenance position and this is a must know
Very good presentation. Thanks
Thanks for this video Jeremy, really helpful and insightful topic!
This was a very thorough and informative video, Thank you so much. It was exactly what I needed.
Excellent presentation! Thank you!!!!
Very helpful and easy to understand. Thank you sir
Why I feel I need to appreciate your good work personally 👍
Excellent video. Thanks for posting.
Love to learn from you. Always easy to understand.
Thank you for making this informative video. I appreciate the knowledge you imparted.
very easy explanation, on the wiring.thank you.
Simple and easy, thanks a bunch!
Very educational and simple! Thanks.
Very nice video indeed! I have done residential wiring and some industrial wiring ,lucky to have learned from very good electricians I worked with. I used to do work and have it inspected but now a days I do my own work or just friends ,family ! I recently helped a friend out who had large commercial air compressor in his business ,the motor just hummed.It was a very big motor and I found the Start Capacitor had gone out as suspected. The motor had more than one capacitor and I assumed it would be the largest one.My bad! I should of used common sense that the start capacitor is only in series very briefly and does not need to be heavy duty ,where as the run capacitor is constantly in circuit and would get very hot if too small! Thanks for your videos ,I always like watching other guys interpretations of things and nuances they may have . Keep it up!
This was an amazing explanation. Thank you!
Thank you so much for your much needed help.
Wow am impressed with the explanation thank you
Amazing video! Very helpful. Thank you!
Thank you very much Jeremy, I have been looking for this info for about a week, hello from Venezuela
👍🏽
Thanks Jeremy, very educational as usual.
Your videos are clean and simple ❤️ No bullshit
Amazing explanation, thank you
Very clear teacher, appreciated!
Excellent explanation, thank you!!
Hi Jeremy, I bumped into your video to get an answer about a motor that read 120/240 V. I got the raw answer I needed, but I couldn't follow you all the way to the end of your demonstration. I'm not tech. savvy enough to take it all in. However, I'll be back. Definitely convinced "You The S#%T".
Thanks so very much,
The Bobbyman
Great videos. Thanks for putting these together!
90% of what you say actually goes over my head because I'm a simpleton. But I love your presentation. Thank you for sharing your knowledge. Someday it will sink in. Diffusion has to kick in at some point.
thank you for making this vid you just saved my project, I build a winch with a 220 motor that was reversible, but when I took off the cover all the wires were missing their numbers so I didnt know how to hook it up.
This video really helped, thanks!
Neat video, thank you for posting/sharing
Nice video. Just what I need. Thank you. I am saving your video
Very interesting. Professor Jeremy. Keep them coming.
You youngman are a wealth of information & thanks for your dedication. 👴👍👏
👍🏽
Thanks. I learned a lot. God bless you.
Thanx! Very informative vid. I’ve got a dual voltage motor I’m tryin to wire to 220 3 phase power and I’ve redone inside the motor from 110 to 220 and now I’ve gotta get it wired correctly to the power. I don’t know the difference between single and 3 phase and how this will apply to my job. I’ll google it and look for more of YOUR vids before I proceed. This is a paper cutter in a print shop that gets used ALOT. I want to make sure I do it right AND put an on/off switch in it, too.
One of the best motor wiring overviews I've seen so far. Nice job. I'm rebuilding a Delta Rockwell repulsion induction motor that is dual voltage and has a physical switch that allows you reverse rotation. This is helpful as the wiring is just old faded cloth so was trying to figure out which windings were paired.
Question, I'm running the motor to a 30 amp rated motor switch (motor is 12 amps at 110) in order to bench test it, but it is not clear which pair of wires to run to "white" and which to "black" in the switch... Or does it matter?
A video hooking up this type of motor or 3 phase to a magnetic starter with remote switch would be awesome!
If your old motor is single phase (sounds like it) it doesn't matter. Load to neutral or neutral to load is only going go change the direction of rotation. If it were 3 phase simply swap a pair to reverse it.
Brilliant explanation. Thank you.
