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 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 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. 👍👍👍
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.
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!
@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 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
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?
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!
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!!!
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.
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.
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.
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.
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!
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!
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)
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.
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.
Goodness, I looked at a dozen motor diagram, this is the first one that gave me the information I need.1 3 5 gets the neutral and 2 4 6 gets the hot wire.
So simple. Thank You. Well explained and illustrated. Verbal show and tell. Love the reverse wire explanation to turn the motor backwards ( if needed ).
How do you know you are not reversing the polarity on the second phase of the motor so one phase is in opposition to the other? How do you know which side of the run windings you connect to the start windings?
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.
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
Wiring motors in my home shop is something I'm quite interested in. This video helped me, and I'd love more. I have three phase as well as single phase (HD milling machine and lathe, plus more). Thanks!
Great video. Thank you so much. I have a question. Should the connection for high voltage be 2-3 and 5 to keep the voltage on the start winding at 120v and not at 240v? Thanks
Great and easy to follow: Only thought is the picture chart with the high voltage vrs low voltage. i.e. Low Voltage 110 would have Neutral and Hot. The High voltage i.e. 220 I don't believe would have a "Neutral". Both sides would be "hot" for 220V.
Absolutely the complicated looking made into simple. A sign of real intelligence. So many make the simple into very complicated which is a sign of overthinking the simple.
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
the fact there is no nominal standard for voltages on equipment always bugged me, especially since 90% of the services i test have 120, just say 120 damn it. (rant over) another spot on video man, well done
120 volts for mains is the poor relation to 240 volts. 240volts is better it charges cell phones up quicker and as it has only half the amps you can have higher amperage equipment. For example in the uk we have 3 kilowatt electric kettles that run of a 13 amp fuse on 120 volts supply the fuse rating would be 26 amps. They say 120 volts is safer but anything over 50 volts can kill you.
There's not really any debate over which standard is better. We all know the higher voltage standards are better, but North America got screwed by virtue of it being the first to adopt widespread use of electricity. I'm sure if we had it to do over again, we would chose a higher voltage, but it's much too expensive to change now.
Hey Jeremy, you are a very good teacher. Wish you would demonstrate how to wire a 220v 1ph motor to a lathe drum switch.. Lots of home shop machinist would love that. Myself included:)
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
Jeremy, your videos are awesome! Thank you very much for sharing your knowledge. It really helps. Since you've asked to share ideas for videos: it would be great if you can cover wiring of single phase induction motors with two capacitors. I suppose one of them is what's called "running capacitor". Thanks in advance.
Jeremy, I have a question about your wiring schematic for dual voltage motors. I have an repulsion 115 230 motor. The two sets of winding for high voltage in your diagram show an N and a H. I assume for neutral and hot. Aren’t both those wires carrying 110 volts to the motor from the switch? This is a Leland motor with 4 wires from the windings previously wired for 110. Can you correct me on this. Also does the stator need to be rotated to one of the two other hash marks on the housing. Thanks
Great demonstration. Thanks a lot. Can you show how we can wire this as three phase and get rid of the capacitor? And if so, is the ROM going to change?
Thanks for posting this video...this will help me a lot in figuring out a motor I have without a diagram. I'd like to send you a pic of the wiring to see if it's reversable from clockwise to counterclockwise if you'd have time to look at it?
7:05: the starter winding can take 240v as shown in the 'high volt' schematic? I thought it was usually: power to L1- L2, L3, L5 connected together - power to L4, L6. In other words, only 120v across starter winding.
thanks so much ! sitting here in Taiwan in front of a air compressor motor that needed to be rewired to 220V from 110V, since 110V draws way too much current (~15A) but as usual, the ****tards painted over the wires and their numbers, no way to know which is what, scratching off the paint wasn't any helpful either ohmed out everything and separated the run & start windings, but had no clue how to rewire the thing thanks to your video i finally can give it another shot, pretty sure its gonna be a success thanks, thanks, THANKS !
Aircraft stripper is your friend next time. I keep a small can around to clean up data plates and leads as required. On new installs I paste wax the data plates, helps them hold up over the years. I use cosmoline spray if they're used outdoors.
Nice clear video. Would suggest the importance of alway making sure circuits are isolated when checking for continuity. A little off topic but example would be checking a fuse while still in the fuse holder.
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!
I think i see a problem. The starting capacitor circuit ,wire 5-6, was powered from 110v in the beginning. After rewire , the circuit is now powered with 240v. I believe you need move where the start circuit is connected. Other websites show it in parallel with one Run winding not both in series. Any thoughts?
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.
So, by reversing start cap 5 and 6, that are wired across the series-parallel circuit 1(with 3&5) and 2(with 4&6), this will cause the motor to reverse its direction? Also, If I have a 240Vac motor wiring the coils in a Series-Parallel circuit, I would have the motor run on 120Vac?- Well explained videos Jeremey, thanks! - Tim
Very helpful video. Thank you for sharing. If I understand correctly, you ended with a 120 connection. Could you explain a 240 connection. Thanks again.
I'm becoming addicted to your channel. For this video, since I'm a visual learner, would it be possible to show a wiring diagram with the windings and starter winding illustrated. I'm try to wrap my head around the wire pairings and how the starter winding plays into things. Many, many thanks for your time and effort to produce these vids.
I would encourage you to draw it yourself. Use the diagram I show in the video around 7 minutes in... then draw the starter winding... the information is there... I think you can create the image from that.
Jeremy, I'm trying to hook up a 240 motor that doesn't have a plate on it. One thing that was unclear is if the direction of the 2nd winding matters. Eg. In the diagram you posted, you listed the series connected like so: 1----2/3----4 Does it matter if I hook the second winding in series like 1-----2/4------3, or 2-----1/3------4 ? If it does matter, how can I tell which direction is correct for the windings?
Can you rewire a single voltage 3 phase motor 440v to run off a 220v 3 phase power supply. I have an old metal lathe with a 1/4hp coolant pump. It's a single voltage 440v 3 phase. I'm rewiring the lathe motor for 220v but that's a dual voltage motor. I'm trying to figure out how to get the original single voltage coolant pump to work with the lower voltage that the lathe will now be running off of. Any help would be awesome. Thank you in advance.
Great visual and explanation. I'm in charge of a woodworking shop when a vintage 15" Bridgewood planer with a wire that has dry-rotted over time When I went to replace the wire (with 12/3), I noticed that ir had a 220 plug in which the ground had been removed so that it could be plugged into a 120v socket. In other word, someone had jerry-rigged the plug. When I put on a new 220 plug, it obviously wouldn't work in the 120v outlet. So I tried it just quickly in a 220v outlet and the motor ran fine for the few seconds i had it on. I checked for a motor plate and then for access to the motor wiring and, unfortunately, struck out with both: no plate and impossible access to the motor without disassembling the unit. Would you recommend chaging the plug and assuming that it will run fine on 120 as it had previously?
I've looked at a thousand vids on this subject and yours! FINALLY! I get the complete picture! Thank you for this wonderful explanation.

You're the only source for such an in depth info.
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!!!!
The resistor analogy & demo was very effective, thanks.
Goodness, I looked at a dozen motor diagram, this is the first one that gave me the information I need.1 3 5 gets the neutral and 2 4 6 gets the hot wire.
135 Neutral 246 hot ! you rock man !!!
Why I feel I need to appreciate your good work personally 👍
So simple. Thank You. Well explained and illustrated. Verbal show and tell. Love the reverse wire explanation to turn the motor backwards ( if needed ).
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 : )
This is just what I needed today to wire up a motor I got recently that had no labels. Thank you so much!
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!!
In the hi and low diagram, souldnt you have conected in the hi side to 110 and 110 to each winding insted of N H load?
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!
There are some trade schools that want you. You are a great teacher.
Great tutorial! Thanks for taking the time to teach us this info!
Fixed mine. It was the thermal switch! Thanks!!!!

I agree more information about this kinda stuff is awesome, you have a new sub, guess I’ve got a lot of videos to catch up on.
Great video. Thank you so much.
I have a question.
Should the connection for high voltage be 2-3 and 5 to keep the voltage on the start winding at 120v and not at 240v?

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.
the fact there is no nominal standard for voltages on equipment always bugged me, especially since 90% of the services i test have 120, just say 120 damn it. (rant over) another spot on video man, well done
🤣
120 volts for mains is the poor relation to 240 volts. 240volts is better it charges cell phones up quicker and as it has only half the amps you can have higher amperage equipment. For example in the uk we have 3 kilowatt electric kettles that run of a 13 amp fuse on 120 volts supply the fuse rating would be 26 amps. They say 120 volts is safer but anything over 50 volts can kill you.
There's not really any debate over which standard is better. We all know the higher voltage standards are better, but North America got screwed by virtue of it being the first to adopt widespread use of electricity. I'm sure if we had it to do over again, we would chose a higher voltage, but it's much too expensive to change now.
Hey Jeremy, you are a very good teacher. Wish you would demonstrate how to wire a 220v 1ph motor to a lathe drum switch.. Lots of home shop machinist would love that. Myself included:)
Jeremy you have a great way of explaining things. It is very understandable.
If you're going to wire a dual motor that has a 110 capacitor for 220 do you have to change the capacitor?
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
@7:07 Does the direction of the windings make a difference ? (Both parallel and series)
I appreciate all the knowledge you share, really.
I’m, I have eight wires on marathon 110 220
So…
Good description of motor windings. Thanks
Jeremy, your videos are awesome! Thank you very much for sharing your knowledge. It really helps.
Since you've asked to share ideas for videos: it would be great if you can cover wiring of single phase induction motors with two capacitors. I suppose one of them is what's called "running capacitor". Thanks in advance.
Jeremy, I have a question about your wiring schematic for dual voltage motors. I have an repulsion 115 230 motor. The two sets of winding for high voltage in your diagram show an N and a H. I assume for neutral and hot. Aren’t both those wires carrying 110 volts to the motor from the switch? This is a Leland motor with 4 wires from the windings previously wired for 110. Can you correct me on this. Also does the stator need to be rotated to one of the two other hash marks on the housing. Thanks
Right On Jeremy. That Was Exactly What I Was Looking For Very Practical. The Example With Resistors Was Awesome.
In the diagram you connected the series to 110 v. Shouldnt you have connected to 220 v.?
Great demonstration. Thanks a lot.
Can you show how we can wire this as three phase and get rid of the capacitor?
And if so, is the ROM going to change?
Thanks for posting this video...this will help me a lot in figuring out a motor I have without a diagram. I'd like to send you a pic of the wiring to see if it's reversable from clockwise to counterclockwise if you'd have time to look at it?
7:05: the starter winding can take 240v as shown in the 'high volt' schematic? I thought it was usually: power to L1- L2, L3, L5 connected together - power to L4, L6. In other words, only 120v across starter winding.
Enjoyed the video btw.
thanks so much !
sitting here in Taiwan in front of a air compressor motor that needed to be rewired to 220V from 110V, since 110V draws way too much current (~15A)
but as usual, the ****tards painted over the wires and their numbers, no way to know which is what, scratching off the paint wasn't any helpful either
ohmed out everything and separated the run & start windings, but had no clue how to rewire the thing
thanks to your video i finally can give it another shot, pretty sure its gonna be a success
thanks, thanks, THANKS !
Aircraft stripper is your friend next time. I keep a small can around to clean up data plates and leads as required. On new installs I paste wax the data plates, helps them hold up over the years. I use cosmoline spray if they're used outdoors.
You youngman are a wealth of information & thanks for your dedication. 👴👍👏
👍🏽
Awesome video, thank you for posting. It really helped me out wiring an old motor that the label was scratched off of.
Thank you for making this informative video. I appreciate the knowledge you imparted.
First class job. Thanks Jeremy
, I'm 7 years old and my name is Ezra. I really like your video!
Thank you a thousand times for all the info your pouring out.
Nice clear video. Would suggest the importance of alway making sure circuits are isolated when checking for continuity. A little off topic but example would be checking a fuse while still in the fuse holder.
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!
Thank you very much Jeremy, I have been looking for this info for about a week, hello from Venezuela
👍🏽
This is such a clear well explained video. Thank you!
This was an amazing explanation. Thank you!
Many thanks, I’ve been trying to get into a maintenance position and this is a must know
Great video, thanks!
What if you have 2 legs of power for your 220V?
Excellent video. Thanks for posting.
I think i see a problem. The starting capacitor circuit ,wire 5-6, was powered from 110v in the beginning. After rewire , the circuit is now powered with 240v. I believe you need move where the start circuit is connected. Other websites show it in parallel with one Run winding not both in series. Any thoughts?
Very good presentation. Thanks
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.
Nice! I needed this since I just picked up a 5hp motor and need to rewire it. A video about speed control would be great!
So, by reversing start cap 5 and 6, that are wired across the series-parallel circuit 1(with 3&5) and 2(with 4&6), this will cause the motor to reverse its direction? Also, If I have a 240Vac motor wiring the coils in a Series-Parallel circuit, I would have the motor run on 120Vac?- Well explained videos Jeremey, thanks! - Tim
Very helpful video. Thank you for sharing. If I understand correctly, you ended with a 120 connection. Could you explain a 240 connection. Thanks again.
I'm becoming addicted to your channel. For this video, since I'm a visual learner, would it be possible to show a wiring diagram with the windings and starter winding illustrated. I'm try to wrap my head around the wire pairings and how the starter winding plays into things. Many, many thanks for your time and effort to produce these vids.
I would encourage you to draw it yourself. Use the diagram I show in the video around 7 minutes in... then draw the starter winding... the information is there... I think you can create the image from that.
Jeremy Fielding thanks! I must have looked away and missed the diagram!
Jeremy, I'm trying to hook up a 240 motor that doesn't have a plate on it. One thing that was unclear is if the direction of the 2nd winding matters.
Eg. In the diagram you posted, you listed the series connected like so: 1----2/3----4
Does it matter if I hook the second winding in series like 1-----2/4------3, or 2-----1/3------4 ?
If it does matter, how can I tell which direction is correct for the windings?
Can you rewire a single voltage 3 phase motor 440v to run off a 220v 3 phase power supply.
I have an old metal lathe with a 1/4hp coolant pump. It's a single voltage 440v 3 phase. I'm rewiring the lathe motor for 220v but that's a dual voltage motor. I'm trying to figure out how to get the original single voltage coolant pump to work with the lower voltage that the lathe will now be running off of. Any help would be awesome. Thank you in advance.
I just discover your channel and it is fantastic. Already subscribed.
Great visual and explanation. I'm in charge of a woodworking shop when a vintage 15" Bridgewood planer with a wire that has dry-rotted over time When I went to replace the wire (with 12/3), I noticed that ir had a 220 plug in which the ground had been removed so that it could be plugged into a 120v socket. In other word, someone had jerry-rigged the plug. When I put on a new 220 plug, it obviously wouldn't work in the 120v outlet. So I tried it just quickly in a 220v outlet and the motor ran fine for the few seconds i had it on. I checked for a motor plate and then for access to the motor wiring and, unfortunately, struck out with both: no plate and impossible access to the motor without disassembling the unit. Would you recommend chaging the plug and assuming that it will run fine on 120 as it had previously?
