How induction motors work

[@bclark11]

The fact that you were able to explain this complex topic in such a simplistic way demonstrates your deep knowledge of the subject. Thank you for putting together videos like this.

[@DukeLaCrosse20]

This is really great. I learned about electric motors in 3rd grade (40+ years ago) and thought I knew how they worked, but this is new to me and I don't think I have ever run across these concepts, even in college physics.

[@tonywatson987]

Now why wasn't I taught this at school, instead of just the theory? Mind, that was 50 years ago! This makes instant sense, rather than just printed words and diagrams. Well done!

[@Electromech]

The army made videos in the ?fifties?, you can find them on youtube

[@PayneMaximus]

There was no youtube at that moment, that's why...

[@tonywatson987]

Electromech Maybe the Army did make films, not videos, in the 50s, but that was for internal use. I never saw a movie at school.

[@tonywatson987]

[@pjharro]

Jonny Deth Interesting, I won't pretend to understand all of what you said but it makes some sense to me.

[@frostycog]

I spent four months learning about motors and in 5 minutes you've been more informative than all those classes. Nice and empirical explanations, good work. This is going to be my go to review video.

[@DBYNOE]

I am an old EE student, home and university trained, these are the best explanations I've ever seen and my father was pretty good at it, thanks for the refresher. I think it would help your audience if you applied your methods to explain why one would use which motor type where, induction motor speeds, and usable vs rated horsepower. Maybe help explain why a fan motor won't power most tools, etc.

[@Gearhart.]

I've repurposed electric motors for my DIY projects for years. The way you just explained that simple electric motor really made a lot of since to me. Thank you, I'll subscribe.

[@johngilson7085]

I like how the magnets have an effect on the aluminum. Many bait cast fishing reels are designed with magnets that apply braking force to slow down a spinning aluminum spool when it is cast. The force can be adjusted by moving the magnets closer to or farther away from the spool. Thanks for sharing.

[@jameserayburn]

Matthias, I really appreciate your method of teaching and the fact that you're very familiar with the subject. Great video.

[@JonasTheLundh]

Just awesome. I could stare at charts and diagrams until my eyes fell out and still not get a complete understanding of these kinds of things, but you make it completely clear in less than 6 minutes.

[@samuelvaz9239]

I'm brazilian, and i speak and understand english, but not very well. You explain and talk so well, confident and with a amazing didatics and home made equipments that everbody can understand and lear the principles envolved. Well done! I agree with Tony Watson below, would be nice and useful we learn at school, but not just teory, but the pratice, with a teacher who can explain with the same mastery as you taught.

[@tomrichardson7761]

Just pulled the motor from an old ceiling fan that runs great, just outdated. It's probably not strong enough to turn into a drill/sander/cutter drive, but you give me lots of ideas! thanks for digging into these concepts!

[@andyp3834]

You sure know how to explain things well, especially to someone who doesn't know that much about this subject, Thanks So Much ! ;-)

[@robdogrobdog9813]

I'm back in baby's arms

[@erikthuys]

The way you explain this stuff is perfect for me.... Im an ship/drillinghip electrician and im coming across with so many different kind of motors.... problem is that its difficult to visualise what and when stuff is happening... This is perfect for me... Thanks for this..... many regards and thanks from Erik Thuys from Belgium

[@Patriot1776]

Matthias, I am glad you occasionally post up videos that have nothing to do with woodworking but instead go in-depth about how common household machines and gadgets work. The educational value of such vids is PRICELESS. Anyway, the video on induction motors I have been showing to railroad enthusiasts to help them understand a little better the traction motors of modern AC traction locomotives and also to help explain why expensive power electronics are needed on modern locomotives to permit active control of the spinning magnetic field's speed and strength. I'm not going to ask you though to do a video about inverters and the like, there are likely plenty of good videos on AC motor field control.

[@randyallaway4085]

Thanks for these, Matthias. A random guy on the internet (me) appreciates you taking the time to explain this stuff.

[@joeyjoosse9301]

i was searching months upon months to learn the diffrence between AC and DC motors but someome finally explained it so i can understand. im dutch and i love your projects

[@harisharanupreti2174]

What I can tell you is that, this man has depth knowledge on subject matters ,not just by theory but by practical as well। He has described in the simplest form, I wish he would have been my school and uni teacher। Thank you very much, you made me smile । May you live longer and longer । 🧡🧡

[@goodgreenbandit]

Thank you Matthias, I feel like I owe you something now. You made it so simple, and answered the questions I was forming watching it before I could ask them. Thanks again!

[@johnfrian]

Your way of explaining electric motors are the explanations I needed to understand how they work. Thank you!

[@СергейКожевников-ь2ь]

Wow man! You've explained all this so clear like no other teacher could do it. Great!

[@tiffany2ish]

Yeah he's my recommended teacher because this is basicly how I learned induction motors is from him

[@jasonvienneau5284]

One of the best induction demonstrations I have seen yet. Thank you!

[@DenatBalla]

Thank you for your videos. I watched your video on the belt sander you build. Thanks to your very thorough explanations I kept watching, one video leading to another, and another, and BAM! I learned something new. THANK YOU.

[@chrisycee]

You know its a fantastic explanation video when you leave feeling smarter rather than confused. Great video!

[@richardsager8126]

Like Tony I've never had this explained so simply. Keep up the good work!

[@sbtoolman12123]

I really appreciate you taking the time to do these videos,they are very helpful,i am not that smart of a guy so i have to watch them a few times to grasp all of what your saying,but thank you for doing this.

[@kensonlama]

god this video is so much better than the other ac induction motor videos on youtube.. good job

[@dout9929]

Man I could watch your videos all day.

[@scottg876]

Best explanation of motors I’ve ever seen. Learned a lot. Thanks

[@homesy135]

I didn't understand it all but I know enough to explain an induction motor to my 12 year old son! Thank you, Matthias.

[@mawanli]

Thanks Matthias, your videos on universal motor and induction motor are very clear and informative. I love them.

[@willgreen5023]

thank you for your videos on motors. Your demonstrations have really helped me understand and visualize what is going on.

[@robertpertuit9530]

Excellent experiments. Hours of work for a few seconds of usable video. But it was really worth it. Great film for any class on motors.

[@shooter289]

Thank you for the video. I really enjoy seeing how this stuff works. I hope to develop my understanding of motor types to the point that I am able to distinguish the types of motors I encounter, and anticipate their properties based on that knowledge.

[@intjonmiller]

These motor videos have been fantastically educational and helpful. Thank you for creating and sharing them! I understand so much more about my tools and equipment at work now. Can I suggest a few ideas for future videos along these lines? I would love to better understand the various ways power is transferred from motors to their load. Direct drive, pulleys (including different types of bushings and how they attach to the shafts), gear systems, etc. Advantages and disadvantages of each. Also methods of alignment and adjustment. I'm sure I'm not the only one who would appreciate your intelligent and straightforward explanations on these subjects. Regardless, thanks again!

[@garypuckering7458]

Brilliantly explained. Took me right back to my high school electrical shop!

[@kk10494]

I really like the direction this and the other motor video are taking, sort of like "Hey I've got this thing, I'll make a video about how it works". Very interesting, hope to see more

[@jeremysaunders9916]

Matthias, I have subscribed. Have been watching a lot of your videos and learnt a lot. Your explanation of your projects and how things work are so clear, entertaining and easy to understand, thank you ,you are a natural teacher. Jez

[@theonlyari]

Thanks for bringing back all of my wonderful memories of my undergraduate electromagnetics class...

[@jaimeskiebel]

I always look forward to your videos, Matthias. Even if the subject matter isn't something I'm initially interested in, you have a way of jump-staring my interest and making me a fan of whatever you are talking about.

[@scott98390]

These are very useful, Matthias; you illustrate these concepts very well. Please continue!

[@TheIlliniviking]

These motor videos go beautifully with what I'm learning in my E&M class. Thanks so much for the great content.

[@tomek]

I wish they had taught me this at school! So much easier seeing a visual representation. Thank you!

[@shaanirfaan3776]

Exactly brother

[@matthiasburger2315]

A very informative video! Even if there are lots of explanations for this everywhere, the way of demonstrating it by taking the motors apart and doing all these experiments, is unique.

[@vallejokid1968]

I hope you start doing more videos like this again. The current LEGO thing is interesting but these are really helpful.

[@TonyGrayCanada]

Another master class - not just in the subject. Your videos are an amazing example of clear, plain teaching. It's a good reminder for my own work that it's not about fancy graphics, it's about how deep understanding produces simple explanations. Wonderful!

[@efranklin85]

Thanks for this video, I've been through HVAC school but never really fully understood induction motors until now. 👍🏼👍🏼

[@galaxypizza5266]

FINALLY !!! In this video you made everything so simple. Thank you

[@bikefarmtaiwan1800]

You have done a really good job of explaining electric motors- well done

[@PepperDeVillle]

Thank you so much! I never really understood the difference between DC and induction motors until now. Your permanent magnet demonstrations really helped me to understand.

[@Walt1119]

Thanks Wandel for all your work producing the videos for us, we really enjoy and learn so much from them! w.

[@learnerlearns]

This is a great new series Matthias! You are a good science teacher too!

[@Enrique_Osorio]

Excellent video. The best explanation I have ever heard on the subject.

[@ketchdegabrielle1228]

Thanks so much for making this video! Very through, simplified and digestible.

[@opensourcedheartspace5263]

Thanks for these clear easy to understand videos. Very appreciated!

[@Tjita1]

I'm really glad we have three phase as standard to all residential buildings here in Sweden.

[@UrzaKenobi]

Cover the new brushless drills next? Thanks Matthias, your videos are always oddly fascinating.

[@Krish0724]

Great work Sir...Your video was very helpful to My Electrical Engineering (EE)....Thank You Very Much...

[@x9x9x9x9x9]

I love this motor series. Oddly enough my buddy posted the previous video on my facebook wall like 2 hours ago even though I had already seen it. The aluminium disk thing is cool. My 3rd grade science fair project was showing how aluminium isn't magnetic unless it is in motion. I used an aluminium disk and a fan motor then mounted a magnet on a hack saw blade above it and when the motor spun up the magnet would move to one side.

[@freewoodencrosses]

You took me back to 1967 electronics school. Great video

[@chevyimp5857]

Excellent. Anyone with an enquiring mind should lap this up. Thanks for the insight.

[@dadurancwf]

Thank You for sharing what You have learned and the wisdom how to bring it to us in a very understandable way

[@just.some.dud3]

Awesome video, Matthias. You should really do a whole series of videos on electronics and electrical engineering.

[@VarionJimmy]

KZbin notified me that this video was published 5 hours ago. Was a bit surprised to see that it actually was 9 years ago…

[@TheLaoruga]

i am amaze by this guy. Every time i watch one of his videos i learn something.

[@forrestberg591]

Great video! Learning about this in my classes now and the visuals help so much

[@richardl6751]

Matthias, you may already know this. You can reverse the rotation of a shaded pole motor by reversing the rotor. Usually the mounting are universal so the motor can be reinstalled either way.

[@humblehombre9904]

Once again, Matt, excellent lesson. Thanks for the info, brother.

[@spanishflew]

Great explanation.Interesting, clear, no nonsense, to the point.

[@dslynx]

Excellent video. The only other time I've seen the magnetic field resistance demonstrated, they would drop a magnet through a pipe and you see how long it takes for the magnet to fall out the bottom as the electricity induced into the pipe would resist the magnet and cause it to fall very slowly.

[@moiseetorres7255]

Thanks man you should be teaching at school you're better than many others

[@JDobsable]

Thanks again Matthias, I'm always impressed with your videos

[@techsguild]

I usually dont comment but I can't let this one go. I just wanted to say thanks for making things so clear for me. I have a EET degree but got into I.T. right after school and forgot must of what was taught since i dont really need it for I.T. However I did need some of this information the other day, thanks... very nice.

[@evanchapmanfanman]

the way that aluminum disc spun when you pulled the magnet across it is caused by eddy currents and that is the same for electric motors as well

[@thedraphter]

Thanks, Matthias, this was a great explanation. I learned a lot, and am very appreciative.

[@JesseStiller]

Is there anything in the world that makes use of the braking effect made by magnetic field (observed with the weight at 1:57)?

[@jimlovesgina]

Regenerative braking.

[@BernhardHofmann]

Thank you so much for this. I've always wondered how they work but the jargon and pages of details seemed too much trouble to bother with. I enjoy your videos and I guess that's why I could watch an hour long explanation by you. You should have a TV show! :)

[@1pcfred]

A TV show is so last millennium. Matthias has their own KZbin channel, which is so much better today!

[@wallacewithoutgromit]

Best concise clear explanation I've seen yet. Thanks. W. Y.

[@GDG-917]

THANK YOU FOR YOUR VIDEO...IT IS REALLY HELPFUL FOR ME TO UNDERSTAND INDUCTION MOTOR...APPRECIATE IN KOREA

[@Akryus]

Great video. I always enjoy learning something new from you.

[@rondj1965]

Well done, excellent video in simple, easy to understand language. Thanks.

[@detlefschmitt2407]

I like your explanation of the shaded pole motor. I think it would be great if you could add another video explaining the electronics behind controlling the speed (rpm) of a shaded pole motor.

[@matthiaswandel]

shaded pole motors aren't really variable speed motors, and definitely not controlled electronically

[@detlefschmitt2407]

people are using dimmers to control fans with shaded pole motors. Is that not an electronic control? It is this kind of dimmer that I am interested in. There is a lot about that online but nobody on KZbin has explained how these actually dimmers work.

[@matthiaswandel]

It is an electronic control. And also a really bad idea to use a dimmer on a motor. Good way to burn out the dimmer and the motor (certainly, if it's anything bigger than a fan motor, you are likely to burn it out)

[@detlefschmitt2407]

Yes, I learned that a light dimmer is not suitable to regulate a fan motor. I was thinking of using a cheap SCR Constant Voltage AC Motor Speed Controller for my table top fan. I was wondering about how the SCR controllers work. Here is one example device: www.amazon.com/uniquegoods-50-220V-Constant-Voltage-Controller/dp/B00QLH8530/ref=sr_1_11?s=hi&ie=UTF8&qid=1470222785&sr=1-11&keywords=electric+AC+motor+control

[@dougankrum3328]

..Shaded pole, and most other AC induction motors have the speed controlled by the frequency of the power applied....

[@TheMetalButcher]

Thanks for that little tidbit about the starting phase click. I'd always wonder why on our grinder, as it would slow down, it would take ages for it to slow down most of the way, then it would click and stop very shortly after that.

[@ryallmackcowling]

Yeah you explain things really well, love your work Matthias

[@bend1483]

Excellent video. Very well explained and easy for anybody to understand!

[@gusmanbhai]

Excellent video, you teaching things wonderfully. Thank you!

[@1stMrSceptical]

As all ways riveting stuff Mr Wandel.. A big thanks from this 'Norff Lunden' Laddie marooned in Scotland…….

[@M64770790]

Much better then others videos found in youtube. thanks.

[@cobiewan]

Matthias, please make a video about your power supply / multimeter / voltage controller.

[@Yellow_cub]

Agreed. That is a most interesting device.

[@justgivemethetruth954]

Excellent video ... the best explanation of this I've seen.

[@khellil2]

This guy is such a good person.

[@marcelobemerguy9055]

The best explanation I've ever had

[@hughe29]

Excellent video, really interesting, love how much time and effort you put into the videos. Would be really interested in more videos along the same lines.

[@cleardesigns4410]

Excellent explanation! Could you also do a video on the correct steps on how to troubleshoot a non working electrical motor? I have several electrical motors (fan, yard blower) that stopped working with good intentions of one day taking them apart to see if I could repair them. Your videos have motivated me to attempt these repairs but I want to do it the right way. Any instructions on trouble shooting will be much appreciated.

[@webbgroup]

Great job on the video. Very detailed and thorough.

[@nateauld]

You are a very thoughtful teacher - Thanks for the info.

[@joeshmoe815]

i dont know if the average viewer likes these kinds of videos here. But.... i luv em - more please - different topics on how to things work =) informative and short

[@Paiadakine]

+1. More like this. Ask a new EE grad how an induction motor works and I bet they don't do as good a job.

[@EETechs]

Pay Way That depends on what area the EE grad wanted to specialize in. Just because you are an EE does not make you have all the knowledge of all things electrical. There are sub classes of the EE field such as: RF, power, analog, digital, communication, electro-mechanical, etc...

[@mark98115]

EETechs I am sorry but that is ridiculous. These are basic principles for any electrical engineer. If someone has a EE from a university and does not understand these things than they are not really an EE. It would be like a mathematician that cannot calculate an area of a triangle.

[@ponkkaa]

Excellent vid! I had always wondered what the copper wire was for in the shaded pole

[@enriquesalasyanez3861]

felicitaciones por todos tus proyectos estoy impresionado y ademas porque el trabajo de cámara es excelente y te lo comento porque mi profesión es camarografo pero me fascina la carpintería yo sigo todos tus vídeos pero es primera vez que me atrevo a comentar tu trabajo que es extraordinario un ubrazo y un saludo desde chile

[@ronaldagee7417]

Thank you for posting these videos.

[@simondezutter6381]

Best video of induction motors ever!
