very good bro
These videos are really well done, great infographics. You should check out real engineering and do a collaboration video.
One of the easiest cheapest ways to support Engineering Mindset. Let the advertisements play through instead of skipping them. Every Ad played through generates revenue for the content producer on RUclips.
i prefer paying him directly rather than being forced to waste time and neurons on advertising
@@mei6487 bro chill out there's lots of people that can use information like this, especially such a comprehensive guide.
@@mei6487 uhhhh yes? There's so so so much amazing content on here, and I'm like kinda preparing to get a master's in electrical engineering lol
If that is true than I would never skip an ad again.
First video i watched i skipped. Will continue watching the rest. Thank you so much. Wish me luck on my new step into becoming a. Sparky.
Always wanted to see an educational animated video like this on DC motors. Thanks!
You're welcome enjoy!
@@EngineeringMindset Soon Brushles dc motor too? Thats the kind thats in the computer fan? Maby a continuing on what determin`s the DC motor torque, speed etc like tho`s in RC cars? :D maby also if you havnt made video about it Dynamo/alternator the difference on engine`s :)
if i remember some what: Dynamo it the old kind of Alterantor thing but it couldnt handle the amps so they started with alternator but alternator makes ac power so it also has Diodes that forces it to dc output? :) Great video allways :D
@@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. ...
@@FreeOfFantasy oh nice :D Thank you for the info :)
Me too.. But i didn't found any channel like this
You do a fantastic job of explaining technical subjects! Great Job!
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'm italian, and your explanation and graphics are much better than other italian channels i've ever seen. You're doing such a GREAT job! Thank you!
Modern cars have DC motors all over including starter, wiper motor, power windows and locks, etc.
what about the main traction motor of an EV?
@@rogerbeck3018 brushless
@@user-mn2cu7yy7q why they use brushless ones?
@@Sepahwand_Heidari cuz dis motor is: more efficient, sparkless, more powerful and more durable.
@@rogerbeck3018 They generally use Induction Motors (Asynchronous Motors)
I love "The Engineering Mindset" . Your explanations are so clear and easy to understand. Thank you for doing this!
Honestly, your videos are the best tutorial videos explaining the basics essential for everyone who starts learning the electricty/motors/other things related to this topic. Thanks for all the efforts you put in making this tuts!
How did humans even come up with this
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
It’s a long chain of knowledge down back to the first civilisations.
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
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.
Man this was the best video of how dc motors are made and work I've ever seen thanks for sharing
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!
Fantastic explanation of DC motors, I look forward to seeing more of your content
Glad you enjoyed. Hit that subscribe button for more
Amazing! You explain things so well. Thank you!
Thank you, Mitch
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!!
You did such a good job on this video, I think it’s great you took the time to ask the audience a question at 2:45! Keep up the good work !
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!
Amazing! You made mechanical guy fall in love with electrical devices.
Easily one of the best explanations I've ever seen. I'm glad I found this channel
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 :)
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.
What’s the difference? Isn’t it still a fan if u attach blades to a dc brush motor?
I knew that.
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.

Wonderful job! I really appreciate what you do with the channel. Such important content with clear visuals and coherent explanation. You're making complicated engineering concepts accessible and easily understandable to the public. Hope you keep up the great work! 😉
Outstanding explanation of DC motors, I look forward to seeing more...
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.

Excellent, very well explained, thanks.
You're welcome
Your videos are consistently brilliant and very educational! Bravo. The first time I've seen the Eddy current described as you did.
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!
It’s been enjoyable watching your videos, I’ve learned a tremendous amount and great job explaining verbally and visually. 👍👍
Glad to hear it!
I just loved it. I always wanted to know how they work. It cannot be more didactic. Congrats.
Thanks, Rafael. Glad to hear
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.
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 👏🏻
Make a video on different types of motors and when to use one. Real life motors available (on smalland large scale-which we could use in projects) .
Do this same with switches.
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

@@triplep4567 what
@@semaantverma "I know, right?"
@@triplep4567 ohhh kk bro
This is mind blowing! Love the details, different views of the motor combined with the animations. Thank you very much!
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.
Thanks! Sounds like you also like to take things apart to see what's inside
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. 😂
@@ds99 programming let's us make our own virtual motors with virtual circuits in a virtual universe where we make the rules.
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.
Check out the new BLDC Motor video: ruclips.net/video/yiD5nCfmbV0/видео.html
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.
Thanks, well it already has inertia so the forces will give it that extra energy
The most informational channel ever!Keep the good work!
Why couldn't you have made this video last Fall when I was in DC class! Amazing video, and awesome channel. I just sent this video to a couple classmates in my CET Test Prep Class. Thank you for all of your content, one of my new favorite channels.
You’re channel is my physics class and probably even better
I remembered the days of diesel electric propulsion on an old navy tugboat, it was endless maintenance and repair.
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
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!
“Inside the copper wire, we find copper atoms.”
Ah yes, the floor here is made out of floor
The floor is made of tiles, made of ceramic.
But your iron nail is made out of iron.
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
Once again I’m reminded, not all heroes wear capes.
Really thanks a lot for the effort you have put to explain, nobody has explained like you thanks a lot I appreciate your work.
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.
I recently took two dc motors from a printer I was about to throw way, I'm not sure what I want to do with them yet though
I had one motor for 6 years. Two weeks ago I used it to repair my pepper grinder. You never know :D
Create a pump!
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.
throw it away because most project require servo motor
Those are Stepper motors, theyre a bit different
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!

Clearly one of the best I've seen about DC motors. Thank you 🙏
Can't thank you enough for all the knowledge you put out there 🙏❤
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.
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!!
This video is incredible. Thank you for making it so simple to understand!
You're a great teacher/instructor, so thank you very much.
Thank you very much sir for giving us your precious knowledge and time.
I had this lesson yesterday and to be honest it wasnt easy and even after watching this video it didnt become easy but it sure did become easier!
Crystal clear explanation and so detailed. Thank you!
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:
I always wanted to know how these work. Thank you!
Already know how motors work but i love Science animation and this in no exception i love your animations

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.
Wow your way of teaching and representing the topic in animated video is very nice ....thanks and keep doing😊
Thank you. Very very good explanation.
Wow! This video is just amazing, I can finally understand how DC motors work. Thank you very much for your great work. ❤🔥
my hair dryer broke down and I took the motor off of it and explored it piece by piece. it was a an amazing experience.
