How To Reverse the Direction Of Universal and Induction Motors: 015

[@talshaharfamily]

Your professionalism and clear information delivery and clean language use is refreshing and enlightening. Thank you, blessings, and keep it up!

[@Jeremy_Fielding]

Thank you

[@joerosburns5639]

You are the best motor engineering and physics teacher I've ever encountered.I have worked in theater and film/tv as an electrician for 40 years. I've tried to learn theory of electricity and motor control as part of my professional development. You are the BEST resource on the internet for straightforward, concise, and lucid explanations of theoretical and practical information!

[@Jeremy_Fielding]

+Joe Ros Burns thank you!

I found a compressor - 21 Gallon 3/4 HP - Craftsman...After watching your video I replaced the capacitor. dressed up the motor switch. And I saved it from the dump and its inow in service in my rear pole barn. Thanks for the videos!

[@ronbpalmer9389]

I find myself coming back to your videos over and over for two reasons when I need practical implementation information 1. You address the needs of someone teaching themselves and 2. Your explanations are very well articulated. I think the fact that you taught yourself keeps you focused on the real world which is very valuable. People who are formally educated are often good at delivering theory but fall short in practical application. I highly recommend your videos to anyone who needs to actually get things done.

[@mwatkins2464]

I don't know if this might help you but thought I'd let you know this. I've been trained and have been in the hvac/r and electrical fields since 1987 and the way we find the common, run and start are by checking ohms. The highest ohm reading is always between the start and run windings, the lowest ohms is between common and run windings . If you want to check what kind of shape the windings are in then After getting all these ohms readings if you add the 2 lowest ohms together they should equal the highest ohms reading. If they don't equal out then there's a problem in the motor windings that may cause a failure very soon. This way is used in checking a compressor on a heating/cooling unit but should also work on motors since the compressor is just a motor also. Take care

[@zsemberigabormate6581]

Precisely explained!! I got the answer for the question I was looking for for 2 days! Awesome, I owe you!

[@tonymann8765]

Getting back to basics- I love it. About 10 years ago, Bill Mayo, a Shopsmith rebuilder in Florida, showed me how to take a Shopsmith headstock motor apart & connect a DPDT switch to have both forward & reverse motor rotation. Kinda like surgery. Like you mention, simply looking for the thinner wires made it easy to locate the starting winding. After the first one, only took 15-20 minutes to do. Bill had spent some time in a motor rebuilding shop. Not sure if they even exist anymore. Thanks for sharing.

[@lesstime1678]

Sir let me tel you a short story, you are exactly like me, i work on 2 motor shops on my life,for about 20 years ,i love motors and generators ,but a"m retiring know but i have so many motors in my house ,,,(all kind motors ,DC ,AC SINGLE PHASE, 3 PHASE, all sizes etc,etc and i can not resist play whit motors, even before i start watch this video i play whit a setup G M (MOTOR GENERATOR ) i have in my basement just to see this babies runing on the bench , let me say that,,,,, you are very smart person and a good teacher ,you know what you are doing,tanks for teaching this stuff the right way , i can see you love motors like me ,good bless you end enjoy teaching ,TANKS

[@jimhester2004]

Fascinating. Very well made, and a lot more logically explained than most videos I see. Having basically no prior knowledge about motors, I'm finding your tutorials very helpful. Thanks.

[@sampickett3843]

Found your channel while surfing. I am now a subscriber. I love great teachers like you.

[@PhillipShockley]

Jeremy You do amazing work. You make really complicated things very simple. You truly understand what you are teaching as Albert Einstein said "If you can't explain it simply, you don't understand it well enough." Thanks!

[@Good-Enuff-Garage]

yeah, tell that to my college professors, ha ha

[@aisotton]

Thank you Jeremy! I just reversed a motor with these instructions so that I can use it for the old lathe that I got. I really appreciate what you do!

[@echobot7100]

Thank you for saving me a lot of time with my project! Your delivery is excellent.

[@georgeeads8689]

I like the way you explain how the motors works. You explain it simply so regular people can understand. Great video.

[@Jeremy_Fielding]

Thank you!

[@dfu1685]

Again outstanding. I thought the speed of your explanations and depth of specifics was perfect in this video. Thank you so much!

[@Edgardocelectric007]

As a electrician your video is a good refresher, I did motor control back when I was an apprentice back in 70s

[@MJCPeters]

I am more knowledgeable today than yesterday, thanks to you!

[@JoeyNarine]

Very good man, very good. You show the common sense practicality that stupid people like me run into...like where the terminals are in relation to the main known common wires. You know how sometimes they talk about red yellow and blue and green and orange with white but then there are other red and black wires and you get confused on which one it is exactly. You showed the location and how it relates to why it is located in said position. You very samrt guy!

[@EmancipatedSquirrel]

I have been subscribed to TPAI before finding your channel. Funny part is I found your channel as a recomendation after watching one of his videos. Have an awesone day! :)

[@kengamble8595]

Looks like you watch about the same stuff that I do ! Also seems like you're doing a lot of the same things that I've done, twenty years ago ! I've always hated wasting anything so would salvage most if not all of parts for my project. I didn't have the Internet for information at the time so you are lucky to have that now. You have good content and are growing your channel so keep it up, like it's said " If you build it, they will come " Thanks for sharing and take care.

[@vincenttelfer4206]

Ken Gamble then make your own video with something interesting.

[@caddiman9834]

I just started watching ur videos and i find them very interesting. Im not into this kind of stuff but i must be honest and admit that u have helped me in so many ways and in helping me use this type of application in motor vehicles. Im a gear head and u would be surprised on how i used ur ideas and methods in cars. So i want to thank u and say keep up the good work and keep enlightening us with ur intelligence. 👍✌️

[@gebular118]

You make very good videos. They are clear, concise, and well presented. You often recommend that viewers research subjects on their own to wake up that creativeness inside them. Your videos are useful and just fun to watch. Keep going!

[@Jeremy_Fielding]

+JOHN GEBHART thank you John. This kind of comment is very helpful to future videos as well.

[@kerrygleeson4409]

Jeremy great work ,you are very clear and easy to listen to and today I have learnt something new thanks From down under Australia

[@bobf12]

good video.straight to the point and no distracting music.

[@vincenttelfer4206]

I'm gonna have to watch this a few more times.

[@seedsman02]

This advice is invaluable mate, I have been looking for you. Wonderfully explained and I now can say hi to the washing machine in the corner lol

[@claytonc.7261]

You are a great teacher my friend.

[@dabradz]

thanks mate .. from Oz .. my son was putting an AC motor on a planer & found your video really good .. U DA MAN !! :-)

[@ford56798]

Great explanation,very clear and understandable! Keep up the good work!

[@TIRCQ]

Came for info years later... thank you for your great work and knowledge share. Greetings from Costa Rica! Pura Vida

[@ronsmerczak5795]

Than you. All sorted, Very very helpful!!!! Got 3 washing Machine motors to sort out. Regards from South Africa,

[@ronblake2585]

Jeremy- I knew you would save me. I bent the shaft of a Harbor Freight band saw and put on a craftsman motor I had only to find it went the wrong way. I went right to you for this video and presto! You're like some motor savant or something. You know your shit. Thanks so much for sharing your knowledge. Ron

[@8ohmrecords]

Your presentation is great buddy, informative and easy to listen to, keep it up!

[@jomatzki]

thanks! i dont know why others cant explain things as easy as you did! :) big help bro.

[@Jeremy_Fielding]

+jomatz tolentino thank you!

[@Jeremy_Fielding]

+jomatz tolentino thank you!

[@boomblooka]

I bought a bunch of motors at an estate auction. Three washing machine motors, a couple beefy old induction motors with capacitor on top, a big 220v motor, one with a gear reduction, and a big variac that they thought was a motor. All that went as one lot that no one else bid on, so I got it for $1.

[@joseluisrodriguez5302]

it´s a robbery Sir !

[@dennistuescher7982]

Just happened to come across your video and liked it so much that I had to subscribe.

[@Tim-kryan]

Thank you for this explanation of how to reverse the direction of motors. I didn't even know for sure if it was possible without rewiring the motor. I made a mount for a motor onto a meat grinder. Once it was all hooked up, the grinder spun the wrong way. 😢 I didn't want to re-mount the motor to where it would be hanging off the back. My motor says on the tag to switch the red and black wires to change CW/CCW. Easy! Thanks

[@gilbus4989]

I think this video might have answered my question about reversing rotation on my drill. Now I have to figure how to wire the DPDT switch to do it manually. Thanks Jeremy

[@GalenCop9]

Excellent video...this should be what I was looking for on a motor I'm wanting to change the rotation on! Thanks!!

[@buddyupshaw6004]

you have opened a new world for me .thanks

[@Jeremy_Fielding]

You sir are why I do this. Thanks for letting me know.

[@JoshuaJonah]

I'm loving this video series. I tend to buy air compressors with broken pumps. A great cheap source of high horsepower motors.

[@mikemichelizzi2023]

Thanks for putting in the work to make these videos. The extra effort like mounting the exposed universal motor to better show its construction definitely helps. I look forward to both more of this series and more of the ways you deal with writing in a small space.

[@arthurf8651]

Thanks for the videos. I have a home shop and all your videos help.

[@willoneill7269]

It's criminal that your channel is not bigger.

[@johnmichaellane1]

Will O'Neill Dang right. I have yet to find better information on electric motors than what's here.

[@FoxMan777]

The bigger his channel gets, the less time he will have to do videos. :D He'll be answering so many questions, he'll never get back to his shop! :D

[@claymationwaves]

No it's criminal

[@aaaricmondroofing1703]

it's criminal ,I don't get notified, been unsubscribed. it is definitely criminal. This cat is one of the best teachers on you tube ,maybe the world.

[@MrLeigh]

First off, very good video. I've watched several and you are very good at explaining complex concepts clearly. I would like to add some input to this video. Motor direction, unfortunately, is not standard across all manufactures. NEMA, National Electrical Manufacturers Association, states that motor direction is determined from the non-shaft end, but many manufacturers state rotation from the shaft end (like you are doing in this video). In an effort to clear up any confusion, some manufacturers are now stating CCWSE meaning counter-clockwise from the shaft end or CCWLE meaning counter-clockwise from the lead (non-shaft) end. I truly only point this out to hopefully help those who may get confused by motor direction as stated by the manufacturer. Again, you do a very good job with your videos. I look forward to more in the future.

[@Jeremy_Fielding]

My source for maintaining this view support.industry.siemens.com/cs/document/60605536/defining-the-direction-of-motor-rotation?dti=0&lc=en-US. I am not aware of NEMA having a different reference

[@MrLeigh]

Jeremy, NEMA MG-1-2016 Rev 2 Para 14.6 - Direction of Rotation - ...the standard direction for dc motors and single phase ac motors is counterclockwise, when viewed from the lead end of the motor. (the lead end is defined as opposite the shaft end of a motor)

[@dustindavy4319]

You're awesome, Jeremy. This was very helpful. I need to reverse the rotation on an attic exhaust fan and for some reason can't find documentation or a diagram online. Thank you!

[@brukernavnfettsjit]

This makes perfect sense. Thanks. I have the diagram for my lathe motor, but I cant read it for the life of me. My head don't work that way.. But Thanks to you I can figure it all out with a multi meter. :D

[@Jeremy_Fielding]

thank you for letting me know... that is awesome

[@bmitchizzle]

Please keep them coming. Very excited for a whole series on your new, industrial robot. Reverse engineering, episodes on individual smart design/engineering elements, maybe a while Jarvis 2.0 where you simply reproduce the giant with considerations/adaptions for its smaller stature.

[@confabrication]

Thanks, Jeremy, for answering my question of 2 days ago and going to the trouble of adding the link. Sadly it is of no help, it being a much larger capacitor start motor, (mine has no capacitor) and also it has the wires all accessible externally. 220 or 110v - the procedure would be exactly the same, I imagine. Thanks again for trying, but I'm now resigned to further searching to try to find the way to get this motor reversed. Maybe I'll dismantle the motor and mess about with the field coil wires inside......

[@Ohm51]

Thank You for explaining some of this ... I am fairly clueless about these things.

[@Jhelm]

Great job explaining. There is only so much you can learn from a book.

[@NathanNostaw]

Great video, Thanks. Clear instructions and easy to understand.

[@patcb829]

What a great video, learned so much.

[@inspectdrone9900]

Jeremy, Love your channel and I greatly admire your work. I have a situation which I suspect a significant portion of your subscribers may find themselves in. Long story short, I bought a lathe to use in my garage. I converted the 3-phase motor to run on single phase 220 volt power using a Static Phase Controller. It works great but only in one direction. However, the 3-position drum switch no longer works. When I start it, the motor (and chuck) only rotates in one direction. The drum switch doesn't change anything. I have found online wiring diagrams on converting 3-phase motors to single phase 220 volts. I have found wiring diagrams for drum reversing switch's on single and 3-phase motors. But I have not come across the wiring diagram for my particular situation. Other details that may help you. 1. SPC: Phase-A-Matic PAM-300HD static phase converter. 2. Motor: Century brand Squirrel-Cage Induction Polyphase Motor (1.5 HP, model number SC-184-FC4-7). 3. Drum switch: 3-position, Cutler-Hammer Forward-Off-Reverse lever-operated switch. 4. Startup switch: A circuit box equipped with a green start button and a red emergency shutoff switch. 5. Magnetic Starter: GE CR306 Magnetic Starter (NEMA size 00) Let me know if this is something you would like to address. Sincerely, Bill

[@nickbecraft4356]

where is the capacitor in the first induction motor in this video? is it built into the motor? I have a DPH224L01 I pulled out of an electric dryer, but I'm having a hard time figuring out how to reverse its direction. Does the capacitor have anything to do with changing the direction? I feel like I have tried to switch all of the leads, but its spins the same way.

[@jimjohnson3076]

Have you tryed to wire a alternator off a car /truck to work as a motor? If not will you ? Thanks jim love your style of teaching thank you.

[@Vanbulance89]

Very helpful and clear video! Thank you. I am subscribing.

[@oxbowfarm5803]

Thanks for the great video and the very generous links to other great motor video. I keep adding your motor videos to my reference playlist. Love your channel.

[@frankewing1769]

Thank you so much for this for this video! I've been a subscriber for awhile and have watched all of your motor posts. Today I finally fitted an old Leland motor to a very old grinder. After being really proud of myself I turn it on and saw that it was rotating the wrong way. My first thought was to Jeremy. I re-watched this video, found how to get into the motor and then changed the polarity on the start windings. It works like a charm. Thanks again.

[@Jeremy_Fielding]

Thank you for letting me know! That is so awesome.

[@dodznb238]

Sir have nice video explaination ...salamat sir..means thank you sir

[@zuluflight5467]

Again- I learned a lot. Thank you very much for uploading Mr Fielding, and i think you believe in jesus, cause your videos are making me calm.

[@TheOpenAirGarage]

Some very good information in this video. Good Job.

[@justchris846]

Great Videos! You really should make one showing how to build an electric motor, where the theory applies to any size build/application. Show things like where to get bearings that the shaft spins on, what type of wire to use, what type of shaft is used to make it and where to find it.. etc..I like your videos. keep up the good work!

[@scania357]

New sub, like the way you explain things. Will be watching more of your stuff. Thanks for posting

[@tomanne12]

wow thank you so much

[@jdwilliams5244]

Thank you for your instruction. I know nothing about A/C motors, but I've come across a large industrial fan. Some DYI person added a one phase motor to it. Looks like an old dryer motor (like the gray one on your left). The motor runs in the wrong direction and blows air out the back. I tried reversing the fan, but it worked the same. I'll take the motor off and try your suggestions. Thanks again.

[@anavan7]

I know nothing electrical but was assuming switch the two cables but wanted to double check. And lo and behold that is what was needed

Very very beautiful video thanks

[@hamzarashad3632]

thank you for suggesting the channel

[@bullockwerks9484]

Jeremy, great video, how do you add a switch that will allow you to reverse the motor without switching the wires?

[@StormbringerMM]

Ha, got the same tach yesterday - thanks for the info, this will be useful in my wiring troubles to bring it back into use. I haven't been able to solve the runaway velocity problem yet - still busy restoring me old lathe

[@Good-Enuff-Garage]

this is absolutely brilliant mate, how can I SUBSCRIBE 1,000 times, ha ha, question for you during the BONUS TEACHING MOMENT how are you recreating the hum, you taught us that it's due to a faulty capacitor, so are you just omitting one? in other words the momentary switch is keeping it off until you press it?

[@timlewis2211]

Cool video, what would you use to slow the speed of say a floor/room drying fan. Permanent applications. Since ur not fond of the Harbor freight one. Tim in Omaha Nebraska

[@shamanking5195]

Do you have any videos on how to test AC & DC motor winding ??? also how would you put together a resistivity meter for underground surveys ???. really enjoy watching your videos . Thanks.

[@dakwman]

another great video. now I have to start looking for motors. Looking forward to #3 way to rock your channel you've got almost twice the subscribers as Grizzly.

[@davesstuff1599]

Love this stuff, right up my alley. I only have five welders.

[@carferar]

You good teacher brv

[@MarkMcCluney]

excellent vid Jeremy, I'll be back soon with my notebook! thanks for sharing.

[@Portrayalpress]

Super videos Jeremy. Well done! Thank you.

[@holmest69]

Hi Jeremy great video thanks, I am trying to reverse to rotation of my capacitor start 1 1/2 Hp single phase motor. I got the motor to spin in the reverse direction when not under load but as soon as i install the belt for the table saw it wont start and makes a loud humming noise. Any ideas? Thanks again for the videos

[@robertcastillo2170]

Very good video through in showing

[@cabraldegah6997]

thank you very much, i had all my answers from your video

[@Jeremy_Fielding]

That is awesome! My job here is done

[@jackdawg4579]

Not sure if a question on this old a video will find you - but for the first motor where you demonstrated how it was simply a matter of switching the starter circuit wires around to reverse the direction of rotation, is there a specific type of switch you could put in line to do this for you? if so what are they called? - I have a belt grinder that it would be great to change the direction of rotation at the flick of a switch.

[@zombieprinting2670]

Just subbed and lovin the channel. Thanks for the clear descriptions :)

[@benchtopwoodworks]

great video Jeremy, thanks for posting!

[@horus2779]

picked up a leaf blower motor very powerful, used a speed controler on it as its controler was not very good, i tried just reversing the power supply to reverse the spin but it did not work, will try reversing bush wires tomorrow, my speed controller off ebay is like yours and is full throttle at about 60-80v , is there a better way to properly control it in finer adjustments. Thanks

[@DagoMongo]

I came into two Bodine gearmotors (NSI-54RL and NSI-33R). My main question, how do I wire the 54RL so I can utilize the F&R function via toggle switch like you have on your lathe. It has two Blue wires and two black wires. Thank you

[@gibbydiy4235]

Hello sir,,, thanks for your time. I've got a craftsman table saw motor that's shot.. I've got another motor to put on it but it says it's not reversible I need it to go clockwise. But this motor is ccw.. can it be done?

[@marktheinventor2481]

That was a light bulb moment (!) for me: spinning that motor up by hand instead of the start winding and then changing its direction. I'm a pretty experienced workshop guy, I guess - but electrical gear always seemed a bit impenetrable and frightening. Not anymore. Thank you so much.

[@ThePwcj]

Thank you for the great info and video. Paul.

[@paulmanhart4481]

Hi Jeremy. I have another question for you. How do I wire a 2 NO 2 NC rotator selector switch to act like a DPDT toggle switch (to reverse my dc motor direction)? I’m having trouble finding information of this sort. Thanks, Paul

[@FoxMan777]

And here it is... :) Thank you! Love the switch-a-roo trick for the starter winding and direction of rotation. I wonder if maybe you could speak at some point on protection (Thermal and Shorting), or point me to a link of something you have already done in video or that you know of somewhere else? For example I have repaired a couple of brushed AC motors for my wife's hand held mixers, because nested down between the tape and the windings was a thermal fuse. They work again, but I don't want to give them back to her until I have some sort of fusing system external to the tape on the windings. I'd love to add a fuse port on the back to make it easy, but I don't think that would address the temperature issue of the windings, only current draw. I know someone will say they are so cheap that you might as well get a new one, and we did go out and bought here a heavier duty mixer (Black and Decker of all things! :D ) But these are her favorites, because one was from her mother, and the other also from her mother is her favorite color and goes along with other kitchen items. She went and used these weaker ones meant for frosting on mashed potatoes. ;) As for sources of motors, I see the same basic sources you just mentioned in this video. It's amazing how much people throw away, and it could so easily be fixed or adapted to some other use. I have this one shop vac that only needs new brushes, but they seem to be proprietary and unavailable. Which also leads me to a question... Who's a good company or source for brushes for electric motors? :) I might be able to find something that will work... Thanks again for your videos! Cheers!

[@Jeremy_Fielding]

I am not sure what to do about the fuse, and I can't think of a good source for what you want, as you are modifying the original design. Brushes are usually very similar in size and shape. You may have to purchase some made for a different machine and shave them to the right shape if needed. At least that is what I would do if I needed custom brushes.

[@jorgenavarro2782]

Thank you God bless you.

[@motomat06]

Awesome video! I have a question. Would there be a way to have the motor reverse automatically say by something breaking a beam for like a garage door opener? Pretty much I’m looking to make something move back and forth on a track on its own. Thanks

[@thejaebeing]

Love your videos. Much respect.

[@NomadMakes]

You, sir, have a very pleasant voice :D I subbed after 10 seconds. Found your channel while looking for a way to reverse the direction of an electrical motor. In short I am left handed. And so I am trying to build my own table saw. That means that I have to reverse the direction of the circular saw motor I am using. And I am totally clueless when it comes to electrics. I guess I have to watch more of your videos. lol. If you have the inclination, stop by my tiny channel and show some support. Cheers from Norway.

[@johnmelia9107]

Hey Jeremy, thanks for sharing knowledge. I was hoping you could help me. I have an AO Smith 1/2 hp ac motor. It has 7 wires coming out. How do I wire this to replace a table saw motor.

[@danwilliams4670]

This is very informative. I have seen many of your videos and wish I had half your knowledge. I have a sewing machine motor and I am researching a way to change the direction of the output shaft mechanically by gearing. I don't have a place to start. Any advice or Ideas would be appreciated. I'm humbly asking as I have seen your understanding of gearing displayed in other videos. Thanks.

[@paulmanhart4481]

Hi Jeremy, I love all your videos. I only wish I had your knowledge of motors. I’m an optical physicist but I can’t understand electronics. Question: I have a Jet 20MF drill press. 1.5 hp. 18 Amp, 1720 rpm 4 pole class E motor. It can be wired for 120 or 240 vac. I want to make it so it can go in reverse, and possibly a variable speed. Any suggestions would be appreciated. Thanks, Paul
