I was expecting explosions..... 😢😔
But sadly the votes for explosions didn't make it
I made a new youtube channel. Can you please check it out and subscribe if you like.

I really like that you always deliberately make mistakes and then explain what caused them. Then you give the right way to do it. That's a really great way for the audience to learn
"I need to make a DC motor. I'll cut some pieces out of this CD case..."
3D printer in the background: *Am I a joke to you?*
@Michael Persico Your point being? He has a 3D printer. You can get an EasyThreed X1 for 90 bucks. The cheapest 3D printer on the planet.

5:08 haha I can't stop laughing about how he picked up the scope and look underneath it. 😃
I love that you use so many goofy little "mistakes" to teach such important principles. I have never taken any classes on any of the requisite topics, but you simplify it to terminology and experiences that help even a turd like myself to be readily absorbed information.
Dude you did a better explanation in 20 minutes than my muppet of a lecturer 30 years ago did in two weeks. People take notice of what he is saying. He's spot on.
Education system is for the basics social skills and knowledge. Your own curiosity is what will actually make you smarter
Edit: knowledgeable would be a better word than smarter but idc
Lecturers hate him! Students love him! Learn electronics with this 1 weird trick!
It might be that you already knew this shit and this was simple enough for you to understand even if you were woken in the middle of the night and made to watch this?
Probably it was explained with all the math in between and not just the concepts.
@@whatever7338 Yup. It's 2 AM while watching this and my mouth hurts from yawning rather than my brain from all this explanation. One thing I am sure that this video blew my sleepiness away.
Mr Mehdi BOOM, I'm an Electrical and Electronics Engineering Graduate (Minored in Computer Science) and now I've a Masters Engineering in Power Electronics and Drives.
On this Teacher's Day, I must say...I wish I had you as my professor during my graduation and even now.
I haven't had this much fun while learning through you as compared to my college while learning stuff.
For What its Worth....I Thank You from my heart for everything you've taught us through this channel.
I wish there be more and more dedicated and enthusiastic people like you. Bless You and Bless Your ElectroCUTE.
"I don't want to assume its gender"... looks underneath it

“Mechanical engineer minions”
Funny how my mechanical professors say basically the opposite. “Oh the EEs will figure it out eventually”
Yep, I think it really depends on what discipline the project manager is as to who they think are the minions.
Actually most of my EE professors did make fun of mechanical and civil engineering.I guess it's a common thing in engineering.
@@mattjmwmatt yep, each field thinks theirs is best... it's too bad more effort isn't put into working together and utilizing each others strengths.
@@WaltSorensen Nah, it's more on the light roast and banther, most of them show respect towards other fields.electrical and mechanical the most because most of the time they have worked with another at some point.
@@mattjmwmatt I still remember my first lesson about AC current vs voltage and the mnemonic was what the lecturer called the "dirty word" CIVIL (capacitive (C) current (I) leads voltage (V), inductive (L) current lags voltage). That was 20 years ago but I switched from electronic to computer engineering soon after, so I have not had a need to use it outside theory.
I'm an EE student and just in this video you just taught me more than my own university professor thank you Mehdi for being in my life
I love how concise this video was, you explained the topic to the level that an electrical engineering student like me could actually understand and not get lost with.
Mechanical engineers rise up! Get your pitchforks and torches ready to overthrow him, he who looks down on us!
But seriously: I'm using your videos to educate myself a bit about the e-tech field and it helps to understand the colleagues from the electrical department(aka. department of witchcraft). Thanks for that.
Department of witchkraft - thx for making me laugh :)
I really wanted some of the info he glossed over lol.
We tend to call them "pixie wranglers" lol
That homemade motor was my favorite thing I've seen in awhile, lol
Thats how it should be taught in schools, but if you ask a question to todays teachers they will spew out the memorised article without actual explanation, because they themselves don't fully understand it the way ElectroBoom does
I made something like that in school!
this is giving me ptsd because i literally passed exams about this last year and it gave me head aches
I watched this video in awe and amazement, but at 75 years old, I didn't understand much! But I couldn't stop watching. Thanks, mate!
It takes almost 1 and half hour just for recording 😵. You're really hard working man. Keep it up. 😊😊
Well it took 3 days, but who's counting

So why are you here sucker xD
I really like your dorky ,down to earth teaching methods.
I have never really had much interest in electronics. But I started building cool stuff like e-bikes , fixing tools and other projects. And they all have an electrical componant. So coming from a guy with a limited electrical background , I wanted to say thanx. Your very simplistic depictions and models, are really helping me increase my intrest,and knowledge.
Your videos are great. You help me look at my work, with “ have fun while you work”, and learn something new at the same time.
As only a mere electrician who has by happenstance fell into a job which entails maintaining/servicing dc drives and motors in an industrial setting this video has done a better job at explaining the theory behind them than the many years of “training” from my actual job. For that I say a huge thank you! Spot on and hello from Alberta!

I hated the Motor topic in my vocational training. I was sleeping most of the time. But I can hear to you for this 20 minutes and I liked it really much. You can teach people pretty good electrical things and you are still funny. Thanks for this
This is my new favorite channel for my electrical knowledge growth. The booms are really helpful (and hilarious) to truly know how all this works.
As a NASA electrical engineer with 28 years of experience, a significant portion of that dealing with controls and motors, I must say...
This video was absolutely spot on.

how did you comment before the video was out??

I have to admit that, this is the best video I have seen explaining the DC motors. Still remember the pain during the motors class old days in university.
Thanks man....
"Low level stuff" - uttered the electrical engineer with regretful spite
And vibrators... off your mobile phones.. aha
I see what you did there.

I dig how you showed us how to make a DIY one. That was seriously super informative and useful, I didn't really fully get it until then. Super awesome channel
I just love how he changes the content of the whiteboard without you even noticing a cut. Really makes me appreciate his video editing skills as well.
Please make a video about MOSFETS
I like the mini pause after the "vibrators of your..."
"The vibrators... ...of your mobile phones".
Not gonna lie, they had us in the first half.
Wanted to know in excruciating detail how the brushed motor control work… and you delivered! As usual, never a dull moments. Now, can you cover brushless motor?
I would love series on all types of motors, their structure, windings usage and such. It's a pretty hard concept to grasp of all the electromagnetic interactions it's sometimes mindblowing how people even come up with these things!
19:24 Brushless or brushed DC motors?
Brushed! I was worried I would confuse the two at some point, and I did!
😂😂😂
@@ElectroBOOM See, I watched and listened to every single millisecond of the video! ;-)
Can we get a video on the difference between brushed and brushless motors? Or I could just look it up I suppose...but Electroboom videos are more funnn. lol
@@Hockleberry The difference is brushed ones are cleaner, healthier and smell better 😉
3:46 who also looked at the clock behind him when the clips faded together?😂
Very cool! Explains how/why my cordless drill stops instantly when you let off the trigger. I knew some of this stuff because I've been into RC cars for many years, but learned plenty too.

As an EE that works on software validation, I remember seeing all this at school in different classes, somethings I had already forgotten other things I never quite understand up until now. Thanks for the great video, this has reminded me why love electronics.
I just realized that this video was in 2019, and it’s now march of 2022. I just wanted to say thank you for all your video’s you uploaded to all of us that believe your video’s are a great way of learning. I would like to know what you know about all of the things you’ve done, I have so many idea’s that I want to do. Thank you again. Stay safe and please keep making learning fun for everyone.
Hi Medhi, a video about how to chose transistors, and emi filters in DIY DC motor would actually be great ! Very nice job on this one, thank you !
I love how when he "rants" about the mechanical considerations of the motors, the clock in the background barely changes.

From his first to last video, they all had one similarity: the intro is "hi" and the ending is the unibrow song or something
And in the middle, he gets hurt and swears.
I have been wondering why haven't you yet made videos about driving mosfets, emi filtering, etc you've mentioned in this video. Your videos are very useful to me personally and I find your ability to dig up, refine and present information to be quite commendable. I tip my hat of to you sir. I learn a lot of new things and even clears up or refreshes many concepts I forgotten. Sometimes I use info from your videos to help my students in class, if not, I just directly say to them to see your video on those topics and tell them he explains it better and he is funny too. I watch your videos even if I m not particularly looking for anything. This video particularly is one of my favorites and have watched it may be a few dozen times while just wondering around your channel. So I think you should do those videos especially on the emi filltering. I would love to see your take on the topic as it is one of things that fascinates me more than any other. Anyways Thanks for reading. Take care. :)
Electroboom doesn't need any insulated gloves. Electroboom is the insulation.
You're a pretentious like-botting piece of garbage.
How are you everywhere!?
I wonder how long until this is top comment
Juystin Y.Is there any place by accident exist out there where i can't see u. just asking.
FUCK OFF
Please make videos about NMOS, PMOS and CMOS and their applications...
I love your antics and style... Maybe if I am lucky I will get one of those Scopes and can actually learn how to use it by watching you... Please keep up the good work and education, and above all else be safe.
This was like 12 videos worth of topics in 1. Very inclusive. I love it.
I had to do this for my E&M Physics lab. Probably the most fun lab I've done in undergrad to date; I even went out and bought all the materials to mess around with it at home as well.
They are in your vibrators!
Of your mobile phones!! 😁😁😁
I laughed too loudly at that one
@@---jq3od what's so funny?
@6:06 I like the distinction of the self inductance of the windings, and the back EMF caused by the rotation. I can't remember seeing it represented that way, and it bothered me(that back EMF wasn't symbolized). So that way of representing it helps it make more sense to me, because again I didn't have a symbolic way to separate the self inductance from the back EMF.
I keep coming back to this one to refresh my memory. Excellent material, sir.
20 minute video? We have been blessed!
Lol thats true
Great vid! I used an H-Bridge IC in an electronics project involving motor control because based on my research I needed one, but I didn't fully understand what it was or why I needed it. This was like a cool origin story for that component. Love it!
ElectroBoom It's Great to Watch you, Always Cracking me up!
very cool video! awesome production and flow of education. my learning blob in my head is learning!
Another fantastic video. I'd love to see one on 3 phase motors.
When do we get a *Full Bridge Driver* shirt?
I watch every video, and I happen to under stand almost anything. Thanks for the clarification on almost all the topics. Further more, how do I enter to wind a scope and/or multimeter
i studied similar things in my master in electrical engineering and luckily i understood the 95% of it, unfortunately when it comes to electronics instead i still have to make some more efforts and study that too, you have a new subscriber keep up the good work :)
We have come a long way since electrocuting guitar memes!
Best channel on youtube! Like!
@ElectroBOOM I am building my own 3 pole motor at the moment and it was amazing to run into you and this video while i am going through this. GOOD video keep it up, and if you can please go in-depth about the topics you left out
ElectroBoom and Big Clive have got to be the yin/yang of youtube electronics channels.
Both are very educational; I prefer the calm Scottish accent of Clive, but I think ElectroBoom teaches me more. It's that slight feeling of terror, the fear of ElectroBoom showing up at my doorstep, and god help me if I can't recount the methodology behind driving a DC motor.
Great stuff!
*0:37** Vibrators ..."of your mobile phone"* 🤣
Just the phones
(19:24) Brushless DC motors ?!? I thought you were talking about brushed DC motors.
Great video !
I think he was comparing
probably a mix up with "brushed DC motor"
You should do a video on soler power and how all that work . love your videos. Keep up the fun 😁
I love the nerding out. Before early retirement, I was in industrial automation and robotics for 30+ years. Thanks for the refresher, need it in my older age, LOL!
Was waiting for a new video all week
Psyco The Psycho Yeah
Oh yeah yeah
Is there any chance you make a serie of videos continuing explaining how to drive a DC motor? I think it would be great to see how to properly switch the mosfets with pwm...
Thanks for the amazing contents!
I want to see how to PROPERLY drive BRUSHLESS DC motors without the commercial speed controllers with that annoying start up safety feature
Thank you for everything I have been learning a lot from you you explain everything very simple and got to love your theatrics
A gnarly topic, well detailed. Thank you!
Well I was designing a project using a brushed high torque gear box. This video has given me the courage to give up.
Use a relay. (And some protection components)
thats when you cheat and find an IC or prebuilt module that does the hard bit for you. No shame in doing that as it saves you time you can spend improving other aspects of your design
''i dont know, i dont wanna assume its gender'' MWWWWAAAHAHAHAHAHAHAHAHAHAHAHAHAHA
THIS CHANNEL IS GOLD I SWEAR
I’m giving away 4 transgender scopes at the end of the video.
He *did* look to see if there is evidence of gender. Reminds me of Gender Bender from Futurama.
for more information on the skipped section at around 3:40
he is talking about how to utilise the right tool for the job, if you only need to apply 1nm of torque then a 5 litre v8 that produces 400nm isnt the right tool. the gearing refers to the ability to change the load while maintaining a speed. if you expect to have more resistance you should use a higher gear ratio (ie 6:1 is more top speed 8:1 is more acceleration) with more rpm
I've been interested how commutators work and now I can see one is done! :-O thank you!

Very nicely made, I like the curve that update to be all nice! Very interesting! What about adding a basic Arduino to generate the signal to drive the MOSFET with more control? I'm sure many people have done Arduino programming but have never seen the output signals on a nice Keysight scope ;)
An Arduino has PWM outputs so it may be possible.
how did you comment before the video was out??
Sniper yea man wtf
If I remember correctly, Patreons get earlier access to the videos.
Time machine.
Interesting! Really awesome to see these motors scaled up. I was a part of the U.S. Coast Guard Cutter Polar Star's crew last year and it was so cool to get to help clean the brushes on one of the three nearly 2 story tall 4.3MW DC motors (While it was running!). They have to be some of the most powerful DC motors in the world. Really a privilege to get to see them in action up close.
Man, I do love your work, experience, and explanations.
I found this channel extremely educational but I wonder why did you choose in this one video to have literally 7 commercial breaks...
I did it!! it wasnt very sparkly like yours but it was fun, i can only get it to spin for like 2 seconds tops, structural issue. Love the videos! old and new
Wow that was some test in speed learning .... thanks
They're used in vibrator
of your smartphones
In Poland we still have in use a lot of electric locomotives with brushed DC main motors, back in time it was too hard for our engineers to develop a proper H-bridges for them, so for power control they used very BIG resistors with huge cooling fans. It doesn't matter how slow was the locomotive going - always it took from power line half of maximum current or maximum current depending when motors were conected in series for start and low speed or paralel for speeds over 40km/h
