@@StigDesign If you build an alternator instead of a DC-generator you can use a three phase generator. That gets you a lot of positive aspects. You don't need brushes at all. That gets you less wear and conductive dust in the system and higher efficiency. The torque is evener then in a single phase system. While you need 6 diodes instead of four they can be a lot smaller. You get better power to weight and size ratios. ...
As a person with modest electrical knowledge, I've always been confused as to how you'd know if a given DC source was built for current to flow from positive to negative, or negative to positive. They're both used all over the place. This video taught me the terms "electron flow" and "conventional current." Confusion resolved! Holy crap, thanks so much! Just found your channel today and I'm going to watch every one of your videos. They're amazingly educational and we'll made.
This video is a God send. I'm currently sitting in my Industrial maintenance course watching this video on the schools laptop because the books they're having us use completely suck. I'm currently in the Electrical Motor Controls for Integrated Systems and it doesn't really explain anything. I've been freaking out because I have a test on Chapter 13: DC Motors, I was so happy and relieved when I found this video that actually explains DC Motors. And a major bonus is it's animated so I can visually see what it does, what the different parts are, where they're located, ECT. Thank you so much, like I said earlier this is a God send. Thank you thank you thank you thank you thank you thank you thank you....... Don't think I can say it enough lol
Just a quick thanks for all your electrical/engineering content - These subjects can initially be difficult to get your head around, but your explanations and animations make learning the principles a whole lot easier. Excellent work and fantastic content!
I have watched a bunch of these videos before, but still like to watch more, because I seem to be sad like that. And as I always do, I always question certain things in my head, because I seem to be sad like that. Then I got to 7:50 and you started answering my questions.. Great video!!

We wanted to turn rock to gold, (alchemy) which led to chemistry, which lead to electrons and then electricity, which lead to electromagnetic forces and then eventually motors, naturally
Ben Franklin was the first to really describe how electricity works Michael Faraday was the first to describe electric fields Everyone else added one or two things over a 300 to 400 years Infact the very first elections were the guys that used electricity to do (magic) experiments in stage using usually static electricity Please note that through all of this there were people that thought electricity was a force only God should play with They even sold pills with electricity in them. Go check that out
Scientific method. Document everything and it will allow you to narrow down discrepancies. Imagine this as a water wheel to crush grain but with electricity ie electron movement.
Note that computer fans does NOT use "conventional" DC motors, but instead uses electronically controlled, brushless motors. These use a opposite construction, where the permanent magnet is embedded in the rotor, and the coils are in the stator. A positional feedback device, for example a hall effect switch or optical sensor, is used to measure the position of the rotor, and then electronically switch on and off the currents to the coil to drive the fan, creating a kind of "electronic" communitator instead of an mechanical one. These work kind of like an variable frequency drive, but uses square wave instead of a smooth frequency, and the frequency is directly controlled by the position of the motor. Most newer computer fans have a PWM input (4-pin) instead of the fixed speed 3-pin one, where the PWN input tells the microcontroller in the fan to adjust its coil current outputs to regulate the speed of the fan.
Or you could just call them what they really are....an AC motor lol. AC motor is the same as a brushless DC motor don't try to sound all smart for absolutely no reason smh
@@chokilotechokilote7906 No he's right. If you connected sinusoidal waveform AC to a BLDC motor it would NOT work. As far as the windings are concerned even brushed DC motors are "AC" since switching polarity is the purpose of the commutator. A BLDC motor is simply electronically commutated hence it's still considered DC.
I can't thank you enough for this video. Im a visual learner and this just helped me a lot as I'm a HVAC Technician and this knowledge is of course essential. Thanks again!
These diagrams and instructions are so well done. The first time I saw a dc motor like this was in the late 60s as a kid. I had a train set and the motor was like this. Later in the 70s I had a cassette tape recorder that that had one. Right now I have a robot vacuum cleaner that has 6 of these types of motors. 2 for the wheels to turn, 2 more for the wheels to levitate over bumps, 1 for the LiDAR mechanism, and 1 for the spinning side brush. I think I’ve replaced 2 of the motors that wore out so far. I know there are brushless motors too which seem to last longer. Not sure how they work.
The Engineering Mindset Yes I have been known to do that. Especially when I was young. My parents grounded me several times for tearing clocks apart and the telephone. Yet I ended up doing computer programming for a living. 😂
Toughnut It’s amazing what can be done now. It makes learning easier when a component can be pulled apart and examined with even motion to see how it works. Very helpful.
Hello. I just want to say that I really love your channel. As a visual learner, I have problems understanding if I dont see exactly what is going on and what is being explained, which a lot of channels and my teacher(explain without visuals). It also doesn't help that I'm new to electricity and physics trying to learn a course on DC and HVAC😅....I'm so grateful for your animations and explanations as well. Stumbling upon this channel was one of the best things that has happened to me :)
This videos are absolutely fantastic. It can be easily noticed how much time and effort you always put on all this. The information is very clear and complete. And the graphic explanation is very high quality. Things become much easier and learning speeds up a lot. Many thanks guys!
You completely lost me when you started talking about the “so and so’s” left hand rule. Then blew my mind when you made it all make sense with the upward and downward combined force resulting in rotation. Bravo 👏🏻
Using tip: A stall current is the current volume when you hold the shaft still, when you are apply or design a product that is using DC motor, please try to keep the rated current (applying current with the product) at around 20%-30% of the stall current. Which especially for the carbon brush motors, high percentage of current creats sparks between brushes and commutators that might causes carbon powder and stay between the commutator segments, that will lead a short circuit.

While quite a large part of the content I've studied during highschool, tech school in the Air Force and college after getting out of the military. It's always good to refresh that knowledge. Because I'm refreshing my prior knowledge of these subjects, I have discovered in every episode something that I didn't know before. So I am continuing my education and because I never know when the additional knowledge will come in handy with the latest job. You have an excellent channel with each subject broken down into easy to understand bites that allow people unfamiliar with the subjects to gain a basic understanding of how the components or circuits will work and why they are important for their ability to make things easier in life. Thank you for the hard work you put into these subjects. And making them simple and easy to understand for people that are unfamiliar with electronics.

Awesome work, Paul. Phenomenal. Looking forward to seeing your DC Generator video. I hope you'll show the direction and magnitude of the EMF generated with the different positions of the armature. Thanks again, Paul.
What you are saying is 2000-year-Old Democritus's model of Atom. This means: for example, if there are 500 objects in your house then there are 500 types of Atoms. But the truth is, there are 92 (naturally occurring) types of atoms which combines in different combination to form 500 kinds of object. I feel Democritus was talking about Molecules without knowing about Atoms & Calling a Molecule an Atom
Oh Man!how do you do these complex animations and make it simpler for us to understand.It takes a lot to do these great stuff!.Hats off to you!.No other youtube channel explains these electronics concepts with such ease and understandable.Thank you
This is by far the most detailed explanation of this subject. Very nice! My one BIG detractor is Paul illustrated with "conventional" current flow (which is totally bogus and confusing to true engineers and scientist). Therefore he used "Fleming's" left-hand rule to describe the motor motion. This would have made an ideal classroom presentation video otherwise.
first of all his videos are well explained, I've learn't a lot from his videos. hey can you do something on generators and how they manage to provide the required voltage and how the coils affect the amount of watts/ volts produced . or if you have please link me to that video thanks
I find your presentations exceptional. The main thing is that the image matches what is being said. There are several types of electric motor designs. There is mountains of information to sort through. Interesting perspective, an axial running through the center of a coil vs a coil offset on an axial as shown in this presentation .
Hi Paul. I'm a recently graduated engineer and working in the HVAC industry. I've got to tell you that your videos have hugely helped me to wrap my head around some of the concepts and principles of chillers, AHU's, FCU's, heat pumps, etc. A technology that I see more and more of is VRF/VRV technology. Could you possibly please make a video on these systems and possibly answer whether they are used as commonly as VAV installations? Once again, thanks for what you're doing. I'm sure new young as well as experienced engineers alike all appreciate it.
Hey Samuel, glad to hear! we talked about those systems here: th-cam.com/video/xwvkojKiLJM/w-d-xo.html there is a vrf detailed tutorial in the works, I don't know when that'll go live but I'll tag you when it does
It's very well explained and illustrated, great job ! I just have some troubles imagining that forces applied to coil 1 through commutator A and B (13:31) make the rotor rotating. It looks like they're compensating.
Leave one for a project that will pop up in your mind years later. The second one, try to disassemble it if you can, you will admire the effort behind it a lot more.
They each have both poles, but the only poles that matter are the ones facing inward toward the coil. That's probably why he labeled them as just north and south.
the other pole is still there. on the other side of the 2 permanent magnets Its probably difficult to illustrate on the program EIs using with shapes that angle like that.
The graphic starting at 5:24 are BRILLIANT! These graphics are a superb way to explain the electromagnetic relationship within motors. Really well done, thank you for sharing this with everyone, it's an incredible tool for educators and learners.
The place of brushes is taken up by electronics. In a BLDC the part with the permanent magnet rotates and the electronics do the commutation without any moving parts.
When trying to determine which way a 3-coil DC motor is going to turn it's better not to use Fleming's left hand rule!! This will confuse a lot of people and it's not accurate!! Instead, you should use the second RIGHT HAND RULE, which determines the direction of the magnetic field of a coil when current flows through it!!
Your explaination is way better than our university teacher. I wish I could have this to help me to understand when I took the course ... Thanks so much.
Easily the best explanation of the details that allow DC currents to operate. Many other youtubers decided to omit the flemings hand rule for the sake of simplicity but it only created more confusion, but you sir decided to keep it in and thoroughly explain it which in the end made the concepts easier to understand.
DC motors can be used to make a LEGO vehicle, and that's actually why I'm here. I'm trying to learn how to make each system within a tank, but with LEGO Technic pieces, except, I want to develop my own. I want to make a tank that can do things like: 1. Move forward or in reverse at different speeds. (requires a gear-shifter) 2. Rotate 360° (One tread moves in reverse while the other tread moves forward with equal torque and speed.) 3. Tread suspension (Traverse heightened obstacles while still maintaining the maximum tread-to-ground coverage for optimized traction.) 4. Contains an isolated turret that can rotate 360° separate from the chassis, and adjust it's cannon at least 35° of total vertical rotation, 30° positive and 5° negative. 5. Autoloading mechanism for the turret. 6. Firing mechanism for the turret that generates enough consistent force for accuracy within a reasonable range. (Not more than 1-3 meters) 7. Camera with sight markers for gauging where the payload will make contact. As for what I want the payload to be, I don't know, but I imagine it needs to be aerodynamic in shape, and must weigh less than 2 grams. Bonus: if I could get a vaporizer and a chamber in the chassis that runs the liquid vapor through a tube, and out through an additional barrel attached to the main cannon, it could double as a smoke bomb that simulates a flame-thrower. Theoretically, I could attach a second tube to the vaporizer that releases smoke to obscure IR/Radar target-locking and vision. Additionally, I would need to attach all of these systems to a controller so they can be operated remotely from the tank. All of these things require me to learn about the relationship between torque and speed, how motors work, as well as many other mechanical and mathematical techniques. This is the beginning, but it's fun learning all of this! So far, I've learned about how much this LEGO tank is gonna cost, which is around 1k USD. and torque/speed functions, and motor functions. Thanks for your help! Incredibly useful information for my lil goal. c:
Bravo! Bravo! Thank you so much! I never understood this trying to read this in textbooks where it just shows the parts of a DC motor - hard to grasp the concept on how it works when they are on pages of a book.
I adore the visualization of electron flow in these. My better understanding is in physics, so I'm always trying to use that to interpret circuits intuitively. It's a lot easier to follow than staring at more abstracted static diagrams. Stellar channel!
IMO you seriously have the best/most informational videos on all of youtube when it comes to this stuff. I love the animations they really help with understanding this stuff. Please keep up the amazing work. You couldnt even Imagine how much your videos help me. Thank you!!!
It couldn't be made more simpler - I rewound it number of times to grasp the content n understood basics! I am on to work with BLDC motors, understanding DC motor will go long way to make me learn BLDC motors- thx

I am an electrical engineer, and haven't truly had a great understanding of the DC motor., until now. Thanks
How can the magnets be individually north and south? A magnet has to have two poles, you can't separate them.
They each have both poles, but the only poles that matter are the ones facing inward toward the coil. That's probably why he labeled them as just north and south.
the other pole is still there. on the other side of the 2 permanent magnets Its probably difficult to illustrate on the program EIs using with shapes that angle like that.
The graphic starting at 5:24 are BRILLIANT! These graphics are a superb way to explain the electromagnetic relationship within motors. Really well done, thank you for sharing this with everyone, it's an incredible tool for educators and learners.
The graphics throughout are brilliant, just especially well done there
Glad you liked it!
Cordless drills have DC motors, right?😉
Also, how do the brushless motors work, what takes the place of the brushes if there brushless?🤔
Some do, yes. I'll make a video on brushless soon and tag you when live
The place of brushes is taken up by electronics. In a BLDC the part with the permanent magnet rotates and the electronics do the commutation without any moving parts.
@@EngineeringMindsetThanks!
Just wanted to say that I love your channel, I've learned so much over this past year!
@@FreeOfFantasy Thanks, I appreciate it!

Awesome illustration!
When trying to determine which way a 3-coil DC motor is going to turn it's better not to use Fleming's left hand rule!! This will confuse a lot of people and it's not accurate!! Instead, you should use the second RIGHT HAND RULE, which determines the direction of the magnetic field of a coil when current flows through it!!
Nice ..nice...nice...video. I am finding this kind video since a long time. It help me a lot to understand my study. Thank You
this video helped me out so much.. cleared all of my doubts on dc motors...
Your explaination is way better than our university teacher. I wish I could have this to help me to understand when I took the course ... Thanks so much.
Easily the best explanation of the details that allow DC currents to operate. Many other youtubers decided to omit the flemings hand rule for the sake of simplicity but it only created more confusion, but you sir decided to keep it in and thoroughly explain it which in the end made the concepts easier to understand.
Best explanation I have ever seen in my life. Thanks bro
DC motors can be used to make a LEGO vehicle, and that's actually why I'm here. I'm trying to learn how to make each system within a tank, but with LEGO Technic pieces, except, I want to develop my own. I want to make a tank that can do things
like:
1. Move forward or in reverse at different speeds. (requires a gear-shifter)
2. Rotate 360° (One tread moves in reverse while the other tread moves forward with equal torque and speed.)
3. Tread suspension (Traverse heightened obstacles while still maintaining the maximum tread-to-ground coverage for optimized traction.)
4. Contains an isolated turret that can rotate 360° separate from the chassis, and adjust it's cannon at least 35° of total vertical rotation, 30° positive and 5° negative.
5. Autoloading mechanism for the turret.
6. Firing mechanism for the turret that generates enough consistent force for accuracy within a reasonable range. (Not more than 1-3 meters)
7. Camera with sight markers for gauging where the payload will make contact.
As for what I want the payload to be, I don't know, but I imagine it needs to be aerodynamic in shape, and must weigh less than 2 grams.
Bonus: if I could get a vaporizer and a chamber in the chassis that runs the liquid vapor through a tube, and out through an additional barrel attached to the main cannon, it could double as a smoke bomb that simulates a flame-thrower. Theoretically, I could attach a second tube to the vaporizer that releases smoke to obscure IR/Radar target-locking and vision.
Additionally, I would need to attach all of these systems to a controller so they can be operated remotely from the tank.
All of these things require me to learn about the relationship between torque and speed, how motors work, as well as many other mechanical and mathematical techniques.
This is the beginning, but it's fun learning all of this! So far, I've learned about how much this LEGO tank is gonna cost, which is around 1k USD. and torque/speed functions, and motor functions.
Thanks for your help! Incredibly useful information for my lil goal. c:
this channel is gold
Wow! This video is just amazing, I can finally understand how DC motors work. Thank you very much for your great work. ❤🔥
Bravo! Bravo! Thank you so much! I never understood this trying to read this in textbooks where it just shows the parts of a DC motor - hard to grasp the concept on how it works when they are on pages of a book.
Glad it was helpful!
Awesome Explaination Bro ,
👍👍👍👍👍👍👏👏👏👏👌👌👌👌💯💯💯💯💯💯💯💯💯💯💯🆒
I understood everything
Superb explanation, best on TH-cam by far.
Thank you. Very very good explanation.
Thank you very much. The video is very useful because I am studying electromechanical engineering.
Now my all doubts about DC motor and Fleming rules are clear , thanks 🙏 for the video
Best videos on here by a country mile, really helping me through my C&G 2365.....
best video ever i watched on motors . great work . thanks
You are the best teacher for me in this world thank you........i am love with you my lovely teacher....
this video is as precious as gold ! Thank you for sharing it.
Really thanks a lot for the effort you have put to explain, nobody has explained like you thanks a lot I appreciate your work.
Your videos are consistently brilliant and very educational! Bravo. The first time I've seen the Eddy current described as you did.
You nailed it Paul 👍
Great direct current motor introduction
The best explanation ever. Thanks!
I adore the visualization of electron flow in these. My better understanding is in physics, so I'm always trying to use that to interpret circuits intuitively. It's a lot easier to follow than staring at more abstracted static diagrams.
Stellar channel!
U deserve billion of subscribers sir.
Very clear explanation and refresh of some electromagnetic fundamental. The best I ever seen.
IMO you seriously have the best/most informational videos on all of youtube when it comes to this stuff. I love the animations they really help with understanding this stuff. Please keep up the amazing work. You couldnt even Imagine how much your videos help me. Thank you!!!
Glad you like them!
Already know how motors work but i love Science animation and this in no exception i love your animations
Thank you!
It couldn't be made more simpler - I rewound it number of times to grasp the content n understood basics!
I am on to work with BLDC motors, understanding DC motor will go long way to make me learn BLDC motors- thx

A tip to easily remember Flemmings rule:
Thumb to mid finger (Force:Magnetic field:Current)
F : B : I
Keep Growing with Knowledge brain with Engineering Mindset.
You are my greatest teacher..
Okey gap nes...
Ramazon oyi muborak...
Fantastic explanation of DC motor.
Glad you think so!
Thank you very much sir for giving us your precious knowledge and time.
Look this video for easy understanding of dc motors really helpful 👍
