Finally, someone who has given the most complete explanation from motor dynamics to control philosophy of the ESC. My compliments on the great effort, much thanks 👍🏻🙏🏻
This is an explanation that a lot of people have been searching for - me included. Considering how most of us struggle to get something working, it's reassuring to know that somebody who clearly understands the subject also spent 3 months to complete the project.
Hey you are the only one who tries to make diy things which are both accessiable and cheap than other youtuber 👍👍👍
you're gifted!!! You know how to teach!
I've been struggling trying to understand and feeling as it was too much for my brain for years and suddenly you've made it simple !
Thanks,Live Long and Prosper ; ) !!!!!
Nice video Thanks so much! The threshold gate voltage for a MOSFET is around 3 to 7V (for high current) 0.7V is for bipolar ones :)
There is not threshold voltage between the drain and the source, only an internal resistance!
I've been doing DIY electronics for sometime now and, I must say without a doubt that this is perhaps the best and most comprehensive video detailing the principles and circuitry. I usually don't comment, but this was beyond awesome
(I'm saying this as a fellow engineer). I'm expecting a lot more of these fantastic videos!
Kudos to you!
Seshagopalan T M wow, your comment means a lot to me and motivates me a lot. thank you very much! Ihope you'll enjoy all of my future videos. keep up and have a great day
It's 30 minutes past 11 PM here, I won't be sleeping tonight until I watch all the videos on your channel!
Seshagopalan T M very true.. I am did not even know hot to start the process of making a esc but I really wanted to make one.. I liked your video and will make a esc too for 60A current..
I would like to make an esc, first i thought i needed hall sensors, but not all moters have them. Thanks for sharing all this great info
This is one of the best videos I have ever seen on UA-cam. You have a gift for explaining complex topics. Congratulations and thanks for all the hard work!
Absolutely Fantastic ! I did electronics 30 years ago, and i wanted an update in sufficient detail to understand how to control these DC Brushless motors. I have been looking for an explanation at this level for a long time and i am delighted that you not only post such great and clear information, but you also share how to build it. Unfortunately i only learn these days, no time to actually make anything. Thank you for posting such a great video, you got a new subscriber. I am in Southern China, if you can only see the amount of Electronics available at the local market, you will want to live here.. a whole building with 6 floors, and about 30+ stalls on each floor. And there ais more than one building here ! Electronic Paradise !
I HAVE BEEN ON UA-cam SINCE NOW A HALF A YEAR LOOKING FOR SUCH A CLIP FINALLY, THANKS FOR THE VIDEO YOU HAVE ANSWERED ALL MY QUESTIONS AND THANKS FOR GOOD DETAILED LESSONS
I am going into 4th year of computer and electronic engineering and I cannot believe I am only discovering your page now. Amazing stuff!
Man: you have done some really awsome job here!!! It is hours I am searcing the web to understand brushless motors and esc and you answers almost all my questions in ones!! Thanks a lot! :) Just keep on making video: you are extremly good in explkaing your knowledge :)
As professional electronics design engineer for safety related parts I am impressed of the explanations of the esc. Very good for beginners and more.
Thank You
Michael
I LUV this newly found Channel! So educational yet enjoyable! 2 Thumbs UP!
This is the first time I understand how an ESC used in remote control cars work.
This is the best explanation I ever see about this topic. Thank you so much for Your help!
This is one of the best tutorials I've seen for this sort of thing. I love you.
Excellent piece of work with a comprehensive explanation. Well done!!
Super informative, solved the EMF myth for me. 🙏🙏🙏🙏
Kamran Aghlami thank you. I'm glad it helped you! I hope you'll like all my videos. keep up
The controller is the hardest concept for me to grasp as it relates to the ability to create the continual rotation and speed in a brushless DC motor. Thanks for tutorial to help understand that without this control the rotation could not be realized.
keep up the good work, been really helpful
Thank you for this video. The information is very detailed and tells me what I wanted to know. I also like how you comment about how difficult it was to do, and how many attempts and documents you had to study in order to get this done right. Obviously it cost more money to build one yourself, then buy something - but this is what you need if you want to learn to make something.
This was an amazing video. I don't see many of this kind on UA-cam nowadays.
I've always been interested in building a motor controller myself and you showed exactly how to do it. Additionally you did an exceptional job at explaining electrical concept (making me realize what I've been doing wrong). It looks like you have put a lot of effort into this project, it's really visible. I immediately subscribed and hope your channel will grow a lot - work this good really deserves it.
I now know that I probably don't want to build an ESC, but this was very interesting. I also think a software tweak could make your motor run more smoothly and efficiently by fading the output in a sine curve instead of just switching on and off.
Paul Hendrix thank you very much. your comment motivates me a lot. thanks again! I hope you'll enjoy my future videos.
I always watch his videos. So detailed and well explained. I like and recommend to new ele-enthusiasts.
This is a very valuable video and I learned a lot! As a fellow UA-camr I know you put a lot of work in this masterpiece. Keep it up!
You will get more speed out of it when you use direct port manipulation in stead of digitalWrite ;-)
Joop Brokking Hi there. You know, I follow your channel for some time. thank k you very much. and yes, the new code has a one input and each sequence is controlled by output registers in order to increase switch speed. thank is a lot!
+Electronoobs quiero comprar 3 con motores esc de 3800 w llamar 931292223 peru
O sea, pretendes que, hable en español, que te llame por teléfono a Perú. y que te venda sólo 3 prototipos, cuando podes comprarlo hecho en ebay o alguna pagina china?. Es para aprender, no para vender. Si no te das cuenta de todo esto vos solo, no creo que sepas cómo usar los motores, simplemente no te da la cabeza
Absolutely amazing tutorial... I first discovered you on Instagram and now you have another subscriber on UA-cam ;)
Very Clear with all details i really love your channel, Thanks for using your time to help others.
Very good explanation. I am looking forward to try it. This is the first video that I found to explain and shows how to replicate a sensorless back emf based ESC. Very good! Very valuable.
I am a software engineer and a electronics noobie even I understood everything from top to bottom. Great explanation.
This is the best video I have seen for electronic speed controller.
Your video is extremely well made. It is a really complex subject, and you just kick butt. Well done !!
OMG thank you. I have been looking for resources on this subject for 4 months!
Bravo! Well done. Now I am looking forward to seeing you make a smaller version and providing more amps. Good Job on your hard work.
The driver you used doesn't provied 11V but way more, there is a charge pump with a capacitor, if you use only N MOSFET the upper MOSFET need a gate voltage higher than you supply 11.1V! (around 7V higher, often twice the supply). The lower MOSFET is easy to drive (11.1V or 0V)
Your explaination would have been compatible with a complementary N and P MOSFET driver 🙂
Hope you will understand 🤗
Great video and explanation!! :D Kudos for the hard work you've put into building the ESC and teaching us all of it for free. (Y) You deserve a lot more subscribers. Thanks so much :)
"We all know the faraday law of induction" Bro I'm just a lost CS student
CS here.. what am I doin here lol.. oh I forgot that I signed up for Hyperloop competition lmfaoo
Bro, go back to you breadth first search and $150k+ salaries, we tryna BUILD over here!
Excellent tutorial ! It has cleared my basics about Brushless motors and ESC. Thanks a lot :)
awesome ... I had just bought irf 3205 a few days ago and I was thinking of making an esc myself ... awesome man awesome ...
dude this is the most easiest bldc drive theory to understand so far. however i did not get the last part where we need to get the value zero in order to get timing for zero crossing or switching time of mosfet.
Don¡t worry. It's simple. Using sensorless motors you can't know when to switch. So by theory the perfect moment to switch the sequence is the zerco crossing. If you make the sum of the 3 outputs should always obtain the zero crossing value. and when the floting signal corss that value you make the switch. quite easy...
Thank you!
This is really one of the best explanations on the web, thank you so much !!!!
this was so good and helpful i didn't mind listening to your English... Great Vid !!!
I would like to express that this is wery perfect explanation of that topic. I had a raw idea, how it is working, but now I understand it all. PERFECT VIDEO, thank you for that very much!
Excellent video and has brought answers to many questions I had about ESCs. Thanks!
I have just recently discovered your channel and must say I am very impressed by the depth and quality of your presentations. I also liked the idea of "beefing up" PCB tracks to handle greater current; I have blown tacks in past both on PCB's and VERO board! The only small criticism is the annoying background "music", totally unnecessary.
Very awesome video mate. Clear, extensive. Very good work!
ELECTRONOOBS you rock! This is the best ever toutorial I found on ESC. Helped me a lot. Expecting more of such amazing videos.
This is really good! Very nicely explained and a fantastic project for learning.

Great video, congratulation! :) It explains the topic very well
This is a great video!!!! I will try to make am ESC of my own from your instructions !!! Thanks!!!!
Just what i was looking for thanks!
looking forward to the hall sensored version tutorial bro, thanks for sharing
thanks for explanation it is the best video on bldc on UA-cam
hola señor, soy de la india, tengo quince años y realmente me gustan sus proyectos y también estoy tratando de hacerlos y divertirme haciendo proyectos arduino.
hey nice work. u have worked hard to build it . :)
electronic _artist_ thank you a lot. this kind of comments motivates me. and yes, it was a lot of work. I want to make it smaller and better.
ELECTRONOOBS Amazing! You're incredibly dedicated to your project and I admire that a lot.
May I ask whether you have any use for this in mind? Hoe about building a really high-powered version of this (something I think off-the-shelf ESCs don't offer)?
This video has been very helpful. Many thanks for your detailed work.
dude just take this huge like from me and if u can make ur videos with no music it will be the best thing ever
You r very hard worker... Great Explaination..keep.it up!
Thanks bro, the explanation is really nice. It's really helpful for me to make my own esc.
En cinco palabras IM PRE SIO NAN TE.
Excelente video. Super currado. Eres un genio. Viva el Talento! Y encima compartido! Buahgg! Muchas gracias!
I finally understood esc thanks to you 😁
Hey man, this is wrong! He explained has nothing see. Believe. Now, You need discovery for yourself.
Very good video, I liked it a lot, thank you very much for your work and greetings from Mexico
Hi, congratulations for the project and the video. You could use this project to make a AC motor inverter using two arduinos, one as slayer firing the mosfets or igbts and one as a HMI for controlling the speed, start ramp, stop ramp...
Thank you very much for this video and it's exactly what I've been looking for. Kudos my friend! :-)
Thanks ! Best explanation i fond so far
Fantastic explain ! Thank you so much for your great project !
Well done! this is a complicated project. I expect to learn a lot. Thanks for your effort
Incredible video!! Helped me so much! I only have one problem, I cannot figure out how the potentiometer is connected to the arduino...Could you please clarify how to connect the pot? Thanks
AMAZING! Thank you a lot!
*Best intro ever* !
its great and working with a little noise.
Many thanks for this video and your many others, great work!
thank youuuuuuu i like you i love you i searching for this video about 2 years
Priceless !!! thank you sir, for such explanation.
Thanks a lot, man! Now I finally learned how it works
Best vid!
hey brother u described in a very lucid manner...thanks for a such quality project...once again thanks a lot!!
Great tutorial mate, keep up your good work :-)
thank you for subs spanish , yeahhh !!! un abrazo muy fuerte desde PERU !!
you are absolutely amazing dude.
Sorry for bad MOSFET explication:
