Wonderful job
Is there a reason you made this ESC video about 'brushless' motors? Do ESC's not generally work with brushed motors?
hey,can i get proteus simulation of this project??
How is possible that a video doesn't have automatic captions enabled...
Can we put timer to when the motor rotate
This is the single best explanation on BLDC motors I’ve ever seen. I really honestly watched it twice it was so good. Learnt loads thank you
excellent animations right!
magnificent work...
true that , this one had best animation coupled with excellent explaination .
i want to know how brushless dc motors controller work
I’ve been watching videos on bldcs, escs and everything for a few years now. This is the single best video I’ve seen yet. It cleared up everything and it’s the first time I actually understand the coil wiring well enough to say I would be ready to rewire a motor myself. Thank you so much. Liked, subbed and commented! Keep on going!
I've been interested in several projects involving BLDC motors, and your video shed so much light and answered so many of my questions. Thanks a lot for making this video!
Been searching for 2 weeks to find an explanation to this. And I’ve found it. Thank you so much!
Thanks for posting this! I'm going to build an Outlaw Pinewood Derby car for our pack's race this month and I'm using a 50mm brushless ducted fan. This tutorial got me up and running so I know my gear is good, I still need to figure out how to incorporate a switch on the nose of the car so it knows when to switch from idle to wide open when the start gate drops but this gets me started! Thanks again!
Dude, I have never seen someone explain something that made so much sense the first time. 👍
Wow, this really helped me out. I was trying to control a drone motor through Matlab and I needed the info that pulse widths are between 1 and 2 milliseconds. I'll try the calibration too at a later point. Thanks for the tutorial!
This is a fantastic explanation, and it lends itself to the point that a brushless DC motor effectively replicates a 3-phase ac motor except with a permanent magnet rotor. Complete with three 2-pole coils that are activated out of phase with one another. Great stuff!
Wonderful video ! Very lucidly explained. I've to say that you are a great teacher and your explanation skills are just what beginners look for . This was so much easier to understand compared to the bldc video made by GreatScott who is another fantastic TH-camr .
I am working on drone from past 1 week , what a timing man .....thanks for this amazing explanation......🙌🙌
sir , i am studying mechatronics engineering right now and i love your channel , thank you
Your videos are so neat, clean, organized and understandable. You work is my inspiration and i will be producing same content as your in the near future INSHALLAH.
iam doing an arduino project for my uni studies involing an rc boat and you helped me very much thank you man! Gonna watch the transmitter video too.
I must say that I like your fan blade used in the demonstration of how to power a bldc motor with an adrino.
Best explanation on bldc motors. You had cleared all my doubts. Thank you so much 🙏🏻
You do such a great job of making your videos informative enough but not loaded down with too much information! Keep up the great work!
Thanks!
Congratulations!
What a clear and simple video explanation. It of, course, took a lot kf time to be done, but, believe-me, it is perfect!
the best explanation and very interesting, thanks so much.
A very well made vid. Had to play 3 times because I got hung up on his accent. Very good explanations and a lot of information. Have a bit to catch up ! Thanks, Bob
Around 8:30, the BEC actually means that when the battery voltage drops too low, the ESC cuts power to the motor to 1) avoid damage to the battery and 2) keep the rest of the controls working (receiver and servos), that feature was introduced to avoid RC plane loss of control and resulting crashes when the battery was too low.
thats just low voltage detection, BEC is what he said it was
2 years on, still a brilliant, helpful video. Thanks buddy👍
This video pretty much contains everything about bldc motors. Nice Video!
Thanks!
مزيد من التالق مهندس وليد. وشكرا على هذه القناة التعليمية الرائعة
Totally one of the best channels for this subject. The work you put into these videos is greatly appreciated
Thank you, I'm so happy to hear that!
Best video about bldc!!!!! Nice work MAN!!!
50 seconds in and i already learned something new!
Excellent explaination. Can you explain the design of regenerative break used in ev.
This is the BEST video I have ever seen. It will help A LOT in my graduation conclusion project. Thank you!
Thanks, glad to hear it!
Exact the information I looked for -> subscribed!
This was extremely enlightening. Thank you! :)
hands down the best video (or even lecture) about BLDC motors.
One (possible) problem: arent the directions of the magnetic field wrong at 0:35 in the coil? If that image were right then there would be bi directional magnetic field inside the coil. If the N -S are right, then the open field lines are right, while the closed loop field lines are wrong.
Thank you! I cannot explain how much I needed this video and how much it helped!
So much respect for you as especially from us beginners. Thank You so much and very helpful as always.
I've slowly been learning about BLDC, and your video is really outstanding! I would have liked to hear a bit more about the advantages / disadvantages of outrunner & inrunner BLDCs. Thank you, and keep up the great work!
Liked / Shared / Subscribed
pls teach how to build brushless dc motor controller board
Thank you, well done and very helpful to me, a new Arduino user.
Really waiting for your project .... awesome
This guys is so damn good. Diagrams are so easy to understand! Not just this one video... All of them! He should have 2 million subscriber.
Simple and clear, thank you!
These instructions are excellent, thank you for sharing. I was able to build and test my motors with a Nano 33 BLE.
One issue I had was that the motor would stop when the throttle was full. Other than that it appeared to work ok
Perhaps the driver has a resistor limiting the current to a value which is less than the current required to run your motor at max speed
100 pts to this video. I'm an electronics engineer I can't find something wrong with it. Very good
Quality explanation dear professor. Haven't you programmed a tutorial on Switched reluctance motor (SRM) yet? Truly you are the best. Best regards
Awesome tutorial, have you considered making one on controlling a BLDC motor with a BLHeli ESC using DShot digital communication instead of the pwm shown here?
Awesome timing, I was trying to build a rc plane with arduino, this and previous controller video helped a lot.
I'm glad to hear that.
Thank you for your great and high quality video. It actually helped me correctly arm and setup my Brushless Motor after two days of searching the internet and watching many low quality youtube videos.
Glad it helped!
Thank you for this video (and all the previous ones)...
especially for tutorials on site that allow easy translation for people whose English is not the native language.
What a very clear and precise explanation. Told me exactly everything I needed to know. excellent video thank you very much
Glad it was helpful!
You rock! best video on this subject! Keep up the good work
New friend here from philippines. Thanks for the enfo
The FritzTube what is enfo? english more... hahaah
The FritzTube what is enfo? more english... haahahah
Best explanation of a DC Motor, nice job!
Amazing video! The animations are simply great. Thank you.
Thank you.. best informative video ..
Very detailed explanation, thanks.
I really like your channel, keep it up!
Thank you!
this video is just amazing thank you!
This guy is excellent & bang on!! Well done!
Great video bro! Just what I was looking for.. Thanks
best explaination.....you explain complex things in so easy way.
Great explanation as always. Thank you for sharing your knowledge.
Thank you!
I defenately enjoyed it !
Love your channel so much! Easy to understand, and nice tutorial video!
Thanks!
Thank u,
that was the best explanation that i have every heard
That means the brushless motor is in fact a symchron ac motor
that is NOT correct. there is NO AC. the output of an esc is three, sequential, DC pwm, signals !!!!!!!!!!!
I really like your videos. They contain some additional information. Keep working like this.
Thanks!
Good bit of explanation on how brushless motors work...
but it's not so much "how to control a brushless motor with an arduino" as it is just how to use the ESC 30A motor controller using PWM as the input signal. From the title, I had expected there'd be a bit about HOW to measure the back EMF, how to keep track of things like electronic commutation, speed, position... but it seems the ESC 30A does that automatically
Nice video illustration.
Could you please tell us which software you have been used to make an illustrated graphics as shown at this video
Very comprehensive and very well explained
I'm working on a college project and combining some of the elements of these robotic tutorials -- I messaged you through Patreon and was hoping you could help me out with the supplies list. I'm getting the list to the lead professor so he can order the components for our build out!
Best BLDC video I’ve seen.
So Simplest and understanding way 👌
Well presented. Clear and simple.
Thank you.
As a new arduino user, this is very helpful. Is there a way to change the frequency using this setup? Like in a variable frequency drive?
This is one video which actually gave any information.
Really nice video, It helps me a lot !!! Thank you
In the motor you used, and most quadcopter motors, the magnets are outside the stator, not inside it as your diagram shows. The reason for this, when the magnets are arranged as a Halbach array, is that you get twice the magnetism applied to the stator in the center.
Beautiful explanation, was really clear
Thanks. very interesting. I am new in arduino based controller. This can be a nice project.
Great video, is the best I could find! Just a question:
The ESC is conected to the "constant" voltage of the batery, and then it generates a signal with the required frequency to spin the motor at those rmp. However, what is the voltage of this signal? Is it always the one of the battery, or does the ESC also regulate voltage (via PWM I assume)?
This is an excellent explanation thank you
Thank you for sharing, is this setup makes the same thing with a servo tester?
Really appreciate your efforts
Super clean vidéo, thanks
This is a great video! I just make simple arduino videos and I have very basic knowledge of how everything works (despite my 2 years of a mechatronics class) and even I understand everything in this video! this is awesome. maybe I'll make a few youtube videos using this knowledge 😁
Still excellent as always. Love this channel. Keep it up bro.
Thanks!
Can you do a video on how to diagnose and troubleshoot the ECM control. Specifically, what is wrong when an ECM motor control that has low power, and the permanent magnet rotor and the 3 phase stator is good? How can the ECM control be repaired and tested?
So, what's advatages / disadvantages of inrunner / outrunner BLDC type ? & Hope you'll make ESC circuit base BEMF someday - Thx for all :)
Really good educative video!
What software was used to create the animations and graphics in this video ?
Great work!
Very clearly explained. Thank you.
Dude u explained it soo nicely tq ☺️☺️☺️
Great video as always! Question though, on 12 pole motor image(at 4:32min), shouldn't be A pole N and not S according to windings?
Q:
An ESC generates 3 phase AC current. And from what I understand the frequency of the AC waveform completely determines motor speed, and the amplitude (peak voltage minus trough voltage) of the waveform is more or less constant. To me this seems like voltage really has nothing to do with determining the speed of a brushless motor.
A:
The torque output of an electric motor is directly proportional to the motor current (not voltage!), and the current (I) is roughly equal to
I=V−εR
Where V is the motor supply voltage, R is the winding resistance and ε is the back-electromotive force (back EMF).
KV and back EMF
The back EMF is the voltage that would be present at the motor terminals as the motor spins without anything being connected to it. This voltage is produced by the motor acting as an alternator, if you will, and it is directly proportional to the rotation speed. The KV rating is nothing but another way to state the relationship between rotation speed and back EMF (KV ≈ RPM / ε). It limits the maximum motor speed at any given battery voltage, because at some KV-dependent speed the back-EMF will "cancel out" the battery voltage. This prevents any more current from flowing to the motor and thus reduces the torque to zero.
When you first power your motor on, the speed is zero. This means that the back EMF is also zero, so the only things limiting the motor current are the winding resistance and the supply voltage. If the motor controller (ESC) was to output the full battery voltage to the motor at low speeds, the motor and/or ESC would just melt down.
Sauce: electronics.stackexchange
Really nice and clear. Thank you.
Very well and neatly explained
7:50 the S means how many cells are connected in series, thus increasing the voltage. The battery can have parallel cells too to increase capacity.
*and max current due to the lower resistance of the whole pack.
what a great mentor. thank you.
Thanks!
Can I ask how you produce your animations? what software do you use?
They are very good.
Great tutorial - lots of good, easy to understand material. 🍺
Thanks!
Thanks, your video saved me.
Really nice ad placement. Really.
Amazing channel 👍
This is going to take along time to learn..................
