Excellent presentation ! In particular, the fact that you went in to the trouble to disassemble the drill and build a wooden stand - to show us the function of the motor - is really remarkable. Also, the idea to use small battery and magnet was just brilliant. It is funny, but this is the best video I have ever seen on electric motors, and it comes from a ...woodworking channel !
You are really wonderful at explaining things. I already knew how these motors worked, but you had me watching with interest all the way through. Thanks. ...... now it's my 6 year old's turn to watch - let's see how he goes...
Wow thanks brother. All the videos out there say "Easy Basics of BLDC, ac, &/or induction motors" but never tear into the motors and physically show the functions of parts included. And your homemade demonstrations of the parts broken down is AWESOME! thanks for the extra effort.
I have worked with electric tools for many years and never took the time to figure out how they work. This was a good explanation. Thanks Matthias for this nice tutorial.
Hello Matthias, I really was impressed when watching your video. As a professor I am preparing my lesson about electrical motors, but up to now had it seen from the theoretical point of view. Your video not only demonstrated that theory works well in practice, but gave me a push in understanding this tiny but mystic machine. Thank you. If you don't mind, I am going to use your video for my lessons, after translating it in german (as I am teaching in Cologne, Germany) and reassembling audio and video with an editing software.
The best videos stimulate curiosity, and this one did it for me. I paused for a moment to understand the back EMF at 3:56, the fundamental basis for a generator....
My dremel is broken, and i have been waiting until i have the knowledge to fix it... And now i can! I found out that the brushes have been worn out. Thanks for the technical video, I would love to see more of these. :D
I think I only understood like 40% of this video, but this is my first time learning about motors and how they work so I'll just keep watching your videos and hopefully one day I'll be an expert on them. Thank you for the useful videos!!
I am amazed by you're intelligence Mathias. I work in industrial maintenance and I've had lots of training and experience with different kinds of motors. This 7 minute video explanation is a great learning tool that is easy to understand. Very well done
You know, I bet the thumbs down are accidental, I was taught this and have taught this occasionally for over 40 years, this is by far the best explanation I have ever seen. There was a science book from, I think the 50's or 60's, that showed how to make a dc motor with a long sewing needle, a cork, several straight pins, some insulated wire and a horse shoe magnet and a 6v lantern battery. It was pretty cool too.
Thank you Matthias that was & great explanation, I've just been watching your fathers shop tour he will be very proud of you your a very clever man, my mission is to build my own bandsaw buying your plans of course, keep up your great work my friend regards Mark.
ive taken University Physics, Physics 2, AC DC circuit's, and Intro to EE (I'm studying Mechanical Engineering) and this is the best illustration and explanation i have witnessed I love your home made work shop and the scientific mind you have!!!
Excelent presentation. Nowdays, universal motors are mainly used, which for me is a surprise, because nobody mentions them. I was opening a hair dryer and noticed that the motor inside is brushed and didn't have permanent magnets, but it is directly connected to AC source, without a bridge rectifier, so I was surprised. Thank you
excellent video... I just repaired the trim motor that controls the outboard motor on my boat... this helped me to understand what the hell I was cleaning up... brushes, springs, commutators, stators.... you rock!
I have been watching every other video hosted by engineers with fancy animations explaining how the motors work and your video is the best by far. Thank, I know I will pass my electrical test tomorrow
This is the best video I've seen that describes how the DC motor works. Forget all the fancy graphics, there is nothing better than someone actually demonstrating it with actual components from a very basic perspective. I have a video coming up that shows a very old (1905 in fact) elevator machine room. There is a DC motor in use and I'm going to briefly explain it, with a link to your movie for a full explanation.
Fabulous. Not being my domain I know little about motors, but always wanted to use them in future projects given I am retired. The subject of motors can quickly get complicated, so your explanation of the Universal motor was most welcome especially since it seems to be the easiest for beginners to tinker with.
2 Things that I like most about your videos Matthias; First, you always learn something USEFUL. The second thing is, you are not a commercial. I love DIY'ers videos, but cannot stand the "I'd like to take a moment to recommend this super product." It nice to see someone doing something because they like it, not for just the money.
Man youre the best physics teacher ive ever had , you made it super clear for me how these uni motors do theire jobs an all time dilema for me ! Great job
Came to the comments right after I saw it to see if anyone else caught that. It really is a great practice. I get a kick out of people that are this stupid. Keeps the Darwin awards coming. Not surprised thought to see such terrible tool handling practices....... He is a filthy wood elf after all.
I've been gaining curiousity of how these work recently, but never really understood it. I understood within 3 minutes of this video. Probably because he used an actual motor instead of diagrams. Thank you!
"Home made voltmeter..." Yes, yes, place that voltmeter right next to the home made wifi antenna, home made tractor, home made guitar, home made full-sized yacht, home made space shuttle, home made fully functional and sentient Optimus Prime - no need for Transformium, no less - and home made large hadron collider. Matthias, we love you and all, but try to soften the blow when you make us feel like underachievers, ok?
You're knowledge of electric motors is really great & well explained in you're videos. I am planing connecting a 240 washer motor to 12 v DC & will probably need you're help with which connections two pair up. Many Thanx........ Stan the Man.....
I'm guessing those 7 (now 14) were either just dumb or Safety Nazis that thumb's downed because Matthias stopped the circular saw blade by pressing down near the arbor with his fingers. Safety Nazis need to get a life!
EXCELLENT!! And the sad part of that is that your skill at presenting really should be the NORM! You stand out because you never said, "Uh" or "Um..." or "You know..." and your camera didn't SHAKE or PIVOT wildly about and we didn't have to listen to you breathe into the mic. Or grunt into the mic. And we didn't have to wait for you to try to remember what to say next..Nor did we have to listen to the unnerving, banging sounds of you dropping things as you looked for your tools or components.Again, EXCELLENT! Very informative! A pleasant and satisfying viewing experience! Thank you, sir.
Excellent! Your video is very, very well done and greatly appreciated. I am a retired teacher of science and appreciate someone who can pass knowledge so well. Best of luck and we'll certainly watch your other videos.
I am an electrical engineer that has experienced for 7 years. And when i opened this video, i believed i would watch an another boring explanation. But after then i really impressed. At the university on electrical machines course we just wrote and wrote for tens of papers of boring theories, at the laboratory just another boring stuffs such as short circuit condition , no load condition etc. Was that difficult to show students, this kind of easy demonstrations step by step? All students could visualize what happens on motor then they could embrace all theories behind easily. So thanks a lot
Matthias you have a wide variety of knowledge, not only as a woodworker and carpenter but also as an electrician and electronic engineer. You make me wonder "What is he gonna think of now?" at the start of every video you upload and leave me saying "Damn!" at the and of each one. Thank you very much and congratulations on the progress you have made in your life.
Hi! I wish I was so lucky to have teachers/professors like you back in those days when I was a diploma student, theories would have been more interesting along with practical, thank you for this wonderful video.
I know this video doesn't have anything to do with shaded pool motors but I've watched some of your other shaded pole motor videos before and they helped me figure out what a shaded pole motor is
Wow! You've inspired me with your wonderful explanation, to take apart a non-working electrical weed whacker motor and see whats going on. Thank you so much for sharing you knowledge.
Because I watched this video last year, I was able to fix my cheap air compressor a few weeks ago. The spring on one of the brushes was broken so graphite wasn't touching so I was getting a lot of arcing. I replaced the old spring with one from a pen and it's been working fine. I'm not sure I would have figured this out as easily as I did if I had not watched this. Thanks.
Because I already know how motors work, I think is the main reason I understood you. This man is a brilliant innovator and a superb craftsman, maybe the very best on RUclips. Who among us is not awed when Matthias unveils yet another machine? I give you the lathe. That machine alone is enough to establish Matthias as Legend , but wait! There's more! Not one to rest on his laurels, Matthias presents the horizontal boring machine. And then the slot mortiser. How about a toddler stair handrail? And what's this - a tilting router lift? A tilting router lift! I know - you got to read that a couple times. That video must be studied, not merely watched. I still haven't quite wrapped my head around it. There's no ceiling here. Matthias produces machines faster than I can grok. True, there are other craftsmen on RUclips who also fly with eagles, but Matthias stands out. First among equals. I admire his work ethic. Matthias packs a lunch and puts a hundred per cent into everything he does. All that being said, may I suggest - and here I feel like one of those annoying know-it-alls, always looking for something to criticize, dreadful bores that they are - but may I suggest, for the videos, an editor, and a script? I know, it's a bit presumptive for a sawdust maker like me to make suggestions to the Top Cat. Matthias, I got you on a pedestal. I am sincerely grateful for all this terrific stuff you do and share, and I wish I lived next door. Lucky for you, I don't.
Thanks a lot for this amazing explanation of the actual motor, most of the videos out there show animated ones but in this one you showed us a real motor. Thanks again!!
Great explanation. Some helicopters still use brush motors as starter/generators. During engine start, 28V DC turns the motor, which turns the engine. Once the engine is started, it turns into a DC generator. We have to replace the brushes during scheduled maintenance.
Now that looks like fun tearing stuff apart and seeing how they work. Where was youtube when I was a kid? I loved tearing stuff apart but I had no one to teach me what any of it was.. Well better late than never!
Matthias does with a couple of magnets and a compass what many other youtubers fail to do with complex graphics. I watched this when it was first uploaded but came back to it when repairing an old Kenwood Chef mixer and wanted to learn more about the type of motor that it used.
Great explanation and demo. I wish I could have seen this when I was in high school. Back then motors were black magic and things to be admired and feared.
Perfectly explained! 40 years ago at school I didn't understand it so well: or I was not enough interested or the teacher was not good enough to explain.
Well done. Takes me back to electrical theory in my college days in the early 60's. I think you've made a better job of explaining than my lecturers. Or I may be just more interested nowadays! Regards.
Cool video! You made the lesson extremely interesting. I'm working on making an electric trike (no welding) and stumbled on your video. Now I'm torn between a drill powered trike or a electric scooter motor (350-500W)! That's a good thing as you have provided me with alternatives.
That's such an awesome explanation of DC motors! The best things you did were to explore a real DC motor and show its limitations! I had some laboratories about DC motors in my uni., but there i didn't even learn 10% of what i learnt through this video! Cheers mate!

As a retired schoolmaster I envy your ability to explain such a, potentially, complex subject in such an interesting way.
Excellent presentation ! In particular, the fact that you went in to the trouble to disassemble the drill and build a wooden stand - to show us the function of the motor - is really remarkable.

You are really wonderful at explaining things. I already knew how these motors worked, but you had me watching with interest all the way through. Thanks. ...... now it's my 6 year old's turn to watch - let's see how he goes...
Now its 12, how did it go???
Love they way in which you explain things, always a wealth of knowledge!
This was honestly the best way I have ever heard this explained
Wow thanks brother. All the videos out there say "Easy Basics of BLDC, ac, &/or induction motors" but never tear into the motors and physically show the functions of parts included. And your homemade demonstrations of the parts broken down is AWESOME! thanks for the extra effort.
This has been explained to me before but the visual makes it much clearer! Thanks Matthias.
I have worked with electric tools for many years and never took the time to figure out how they work. This was a good explanation.
Thanks Matthias for this nice tutorial.
Hello Matthias,
I really was impressed when watching your video. As a professor I am preparing my lesson about electrical motors, but up to now had it seen from the theoretical point of view. Your video not only demonstrated that theory works well in practice, but gave me a push in understanding this tiny but mystic machine. Thank you.
If you don't mind, I am going to use your video for my lessons, after translating it in german (as I am teaching in Cologne, Germany) and reassembling audio and video with an editing software.
I've seen, read and heard heaps of DC and AC motor explanations, and Matthias sums it up beautifully in less than 10 mins!!!
Best motor/magnet explanation I have ever heard or given.
The best videos stimulate curiosity, and this one did it for me. I paused for a moment to understand the back EMF at 3:56, the fundamental basis for a generator....
My dremel is broken, and i have been waiting until i have the knowledge to fix it... And now i can! I found out that the brushes have been worn out. Thanks for the technical video, I would love to see more of these. :D
I think I only understood like 40% of this video, but this is my first time learning about motors and how they work so I'll just keep watching your videos and hopefully one day I'll be an expert on them. Thank you for the useful videos!!
You do a great job explaining this to someone who isn't familiar with this topic. Thank you!

Well explained! I'm looking forward to the induction motor video ☺
thats brushless
Very helpfull,tks

I've seen some great explanations of how DC motors work, but the visual demonstration with a real rotor takes this waaay over the top. Thank you!
Very good explanation of how a common motor works.
Thanks for the video Mathias,
Roland
I ve watched many of your videos and I have made furniture out of your plans. You are a gifted teacher.
Hell yeah, this just is so well explained that it's downloaded into my memory now.
You know, I bet the thumbs down are accidental, I was taught this and have taught this occasionally for over 40 years, this is by far the best explanation I have ever seen.

I always love taking things apart and see how they work thanks :)

Really great explanation! Thanks!
I went through many videos on youtube reagrding DC Motors but after watching this video my concepts are far better now..Thank you
awesome video, if only my college teachers would have explained it like that.......
Many teachers lack the art of teaching

The irony is that those who should actually be teachers, don't want work as teachers. And vice versa. Often same for politicians too

@2:22 you got a WOW effect for the clear explanation of the way these motors work. a BIG thumbs up 👍
I was always curious what they meant by brush vs brushless motors. Thanks Matthias!
realyy???
ARTASH SARGSYAN No. The contacts on the slot car shoe were there to provide voltage to the brushes on the car's motor.
ARTASH SARGSYAN good
ARTASH SARGSYAN .
Yup
I have been watching every other video hosted by engineers with fancy animations explaining how the motors work and your video is the best by far. Thank, I know I will pass my electrical test tomorrow
Wow, after 26 years I finally get it!
You are one of top guys on RUclips who explain things amazingly clear without any 3D animations 👍
Matthias Wandel ,, thank you sir for the very clear explanation and the amazing video.
z
Simple and direct tutorial.... and now i know what is wrong with my old cordless drill. Solid work man
Bah I thought Matt was going to build a superhero suit from DC Universe: Motor Man!
But this video is also good.
My god... *eye roll*
This is the best video I've seen that describes how the DC motor works. Forget all the fancy graphics, there is nothing better than someone actually demonstrating it with actual components from a very basic perspective.
I have a video coming up that shows a very old (1905 in fact) elevator machine room. There is a DC motor in use and I'm going to briefly explain it, with a link to your movie for a full explanation.
You would be very valuable in a real classroom!
Fabulous.
Not being my domain I know little about motors, but always wanted to use them in future projects given I am retired.
The subject of motors can quickly get complicated, so your explanation of the Universal motor was most welcome especially since it seems to be the easiest for beginners to tinker with.
In an end of the world situation where only 100 people get to leave earth on an ark, Matthias would get a ticket.
not me. no ticket for me. i'm not doing anything unique or important.
I'd want him to design the ark too
Excellent demo!
O9lk
So if I want to make a generator instead of having a laminated core made up of many small sections I just have a solid steel core since I want emf?
2 Things that I like most about your videos Matthias;
First, you always learn something USEFUL. The second thing is, you are not a commercial. I love DIY'ers videos, but cannot stand the "I'd like to take a moment to recommend this super product." It nice to see someone doing something because they like it, not for just the money.
wish i had a physics teacher like this back in school :-/
Man youre the best physics teacher ive ever had , you made it super clear for me how these uni motors do theire jobs an all time dilema for me ! Great job
My favorite part is when he stopped the circular saw blade with his hand.
Noble909 Strangely enough, the safety trolls have not picked up on that!
It's not that dangerous
Matthias has settled down somewhat, remember when he used to use his tongue, ahhhh, those were the days, ribbet!
Came to the comments right after I saw it to see if anyone else caught that. It really is a great practice. I get a kick out of people that are this stupid. Keeps the Darwin awards coming. Not surprised thought to see such terrible tool handling practices....... He is a filthy wood elf after all.
I like the part where he stops the blade with an orphans softspot
Well done, finally a demo on converting a universal motor into a DC motor, you saved me a lot of time, thank you very much indeed.
i wish u were my science teacher
I've been gaining curiousity of how these work recently, but never really understood it. I understood within 3 minutes of this video. Probably because he used an actual motor instead of diagrams. Thank you!
i couldn't be more fascinated. great video. are all induction motors brushless?
Fascinating! As someone who knows nothing about such things I wasn't expecting to understand much, however you explain it very well, thank you!
"Home made voltmeter..."
Yes, yes, place that voltmeter right next to the home made wifi antenna, home made tractor, home made guitar, home made full-sized yacht, home made space shuttle, home made fully functional and sentient Optimus Prime - no need for Transformium, no less - and home made large hadron collider.
Matthias, we love you and all, but try to soften the blow when you make us feel like underachievers, ok?
Surely all large hadron colliders are homemade.
You can hardly buy them on amazon.
:-)
Lol
This is the best explanation/demonstration I've ever seen. Brilliant!
0:04 Did know one else see that?!?
I'm guessing you're surprised that he touched the spinning saw
what? you never saw a man touch a smooth spinning surface before?
:0
This is the best explanation of a motor I have ever seen, heard, or read. Thank you, sir!
Hard to believe somebody that can make their own voltmeter would stop a saw blade with their hand
tnf. the cutting section of blade was well guarded when he stopped it by hand..
There's a difference between knowing your tools and being some dumb safety nazi commenting on youtube..
You're knowledge of electric motors is really great & well explained in you're videos. I am planing connecting a 240 washer motor to 12 v DC & will probably need you're help with which connections two pair up.
Many Thanx........ Stan the Man.....
Before watching this, I understood parts of how those motors work, this video has filled in the empty spaces very well. It's a like from me :)
7 people didn't get it
I'm guessing those 7 (now 14) were either just dumb or Safety Nazis that thumb's downed because Matthias stopped the circular saw blade by pressing down near the arbor with his fingers.
Safety Nazis need to get a life!

well I didn't fully get it... but I liked it!

EXCELLENT!! And the sad part of that is that your skill at presenting really should be the NORM! You stand out because you never said, "Uh" or "Um..." or "You know..."
and your camera didn't SHAKE or PIVOT wildly about and we didn't have to listen to you breathe into the mic. Or grunt into the mic. And we didn't have to wait for you to try to remember what to say next..Nor did we have to listen to the unnerving, banging sounds of you dropping things as you looked for your tools or components.Again, EXCELLENT! Very informative! A pleasant and satisfying viewing experience! Thank you, sir.
Lost me about 5 seconds in to this video!
You mean when he stopped the circular saw with his hands? @0:05. Safety Man!!
I recoiled my fingers so fast when he did that.
Get over yourself...
Oh look, another safety Nazi that isn't good at anything else. You sure you and I didn't serve in the same Army unit?
Excellent! Your video is very, very well done and greatly appreciated. I am a retired teacher of science and appreciate someone who can pass knowledge so well. Best of luck and we'll certainly watch your other videos.
You are a good man
Your videos are so useful for us here in Qatar and Egypt
Thank you one million times
That is the best demo I have seen on universal motors.
I am an electrical engineer that has experienced for 7 years. And when i opened this video, i believed i would watch an another boring explanation. But after then i really impressed.
At the university on electrical machines course we just wrote and wrote for tens of papers of boring theories, at the laboratory just another boring stuffs such as short circuit condition , no load condition etc.
Was that difficult to show students, this kind of easy demonstrations step by step? All students could visualize what happens on motor then they could embrace all theories behind easily.
So thanks a lot
Thank you for taking the time to show us how a motor works
Fascinating! I learned more from this one video than I did in 2 years of Physics lessons at school.
Thank you Matthias for taking the time to make such a good video.
Matthias you have a wide variety of knowledge, not only as a woodworker and carpenter but also as an electrician and electronic engineer. You make me wonder "What is he gonna think of now?" at the start of every video you upload and leave me saying "Damn!" at the and of each one.

Hi!
I wish I was so lucky to have teachers/professors like you back in those days when I was a diploma student, theories would have been more interesting along with practical, thank you for this wonderful video.
wow this made the most sense out of all the electric motor vids/turbine vids i've been watching. thanks.
Your test rig with the rare earth magnets gave me a great idea for a project. Thanks!
I know this video doesn't have anything to do with shaded pool motors but I've watched some of your other shaded pole motor videos before and they helped me figure out what a shaded pole motor is
Wow! You've inspired me with your wonderful explanation, to take apart a non-working electrical weed whacker motor and see whats going on. Thank you so much for sharing you knowledge.
i finally understood *why* the rotation works and especially why it starts, thank you!
Simple and clear explanation with a lot of practical examples, perfect video!!!
No bullshit presentation. Thank you. Wonderful human being.
Because I watched this video last year, I was able to fix my cheap air compressor a few weeks ago. The spring on one of the brushes was broken so graphite wasn't touching so I was getting a lot of arcing. I replaced the old spring with one from a pen and it's been working fine.

Very well explained, there are tons of videos but this one is best video to understand how DC motor works
Videos like this are why this channel is awesome.

This was one of the best explanations I've seen on the operation of motors. Thanks!
You are crazy smart Matthias. I didn't understand a word of it, but enjoyed it anyway. Love your videos!
Now that looks like fun tearing stuff apart and seeing how they work. Where was youtube when I was a kid? I loved tearing stuff apart but I had no one to teach me what any of it was.. Well better late than never!
Well done. I like the hands on and incremental explanation. It works very well for universal motors.
Matthias does with a couple of magnets and a compass what many other youtubers fail to do with complex graphics. I watched this when it was first uploaded but came back to it when repairing an old Kenwood Chef mixer and wanted to learn more about the type of motor that it used.
Great explanation and demo. I wish I could have seen this when I was in high school. Back then motors were black magic and things to be admired and feared.

J'aime beaucoup votre compagnie.Vos experiences sont tres allechantes.
That's such an awesome explanation of DC motors! The best things you did were to explore a real DC motor and show its limitations! I had some laboratories about DC motors in my uni., but there i didn't even learn 10% of what i learnt through this video! Cheers mate!
Thanks so much for this video,I have had countless drills go kaput on me that i have opened up for inspection, Always wondered how they truly work
You are just good for your explanation. Very easy to understand.Thanks a lot.
I learned more about electrical motors in this 7 minute video than I have in my entire life.
