The best explanatory video of BLDC working principle so far. Thanks
Apart from being charming- the lady has eloquently explained the basic working of BLDC- Thx for information
Thanks very much. These series will make me understand it all. In the first 5 minutes i'm already getting the principles, which i didn't before :-)
Simple and Easy to understand Animation. Explanation is in complete synchronisation with the animation.
Nice tutorial! Coming from a CS background and find this easy to understand!
FOC control is hard but the result is so awesome.
Thnx, great explanation, a simple little detail, like demonstrating and incuding the changing magnetic field (in yellow) was for me the "ah- ha" moment. I pressume that the directional momentum assist in the fluent chance over of the poles.
Thanks for a great video series. Very informative
Excellent and succinct explanation and demonstration.
This was really helpful, thank you!
Really good information. Best way of presentation.
Excellent presentation! Should have more views.
Simply great!! Simple and rigorous!!❤
A helpful video! Thanks!
Vous avez fait un très beau travail, en plus d'être très jolie ! Merci !
Brilliant Explanation. Simple and Lucid Language
Thanks for this informative session! But can you plz explain the control circuit?
Explained very well; thanks!
Better easy understand and visualize...lot of thanks
This is an excellent presentation .. thank you!
Would have been very useful to make mention of the distinction between in-runner and out-runner BLDC motors when defining terminology so the rotor and stator references were less confusing for anyone working with hub motors.
The explanation and the animations are really help full to understand the principle. Nice approach.
This is amazing content. Thank you.
Hey can anyone please tell me how to add 4 teminals to the BLDC?
Mine BLDC has only two terminals
Great video!
This is really well done! thanks!

thanks for the excellent explanation of the working of a bldc motor control and i have a question as i have noticed that you are using the a dc dc pwm generator. so, I wanted to know whether we can implement other types of PWM techniques like SPWM and SVPWM techniques and how it can be implemented on this modle? thanks

I'm a hobbyist. Several years back I tried to design a stepper driver using SPWM. It's referred to as micro-stepping. It allows a stepper motor to be more precise and much quieter. It's perfect for a CNC machine.
If BLDC motors were used for robotics maybe SPWM would be useful but otherwise PWM works just fine.
Great Video
great video, thanks a lot!
Thank you so much!
Thank you Melinda
Perfect content
What are the hardware requirements for building a controller??what kind of processor we need
nice tutor...good work
great video !!! like it!!!
Helpful AF
Good presentation 👌
Drone"larda 36 kutuplu bldc motor kullanılıyor, 10 derece acı farkıyla bobinlere enerji vermeliyiz ancak bu durumda 120 derece olan iki faz arası acıyı nasıl açıklarız
Good work
Thank you very much
Anlatım için teşekkürler!
Great, thank you!
does BLDC controller has an additional resistance that adds to the Phase coils of motor to control the current?
Best wishes 🤗🤗
thanks. great collection. Im looking for the "links below"
Thank you
What if I give 60v to 48v designed bldc motor how back emf will effect performance of bldc motor or controller
Greetings from Türkiye Dear Melda Ulusoy
Very good
what was the next word you said after '' We can simulate a.....'' i dont get that..
An issue is confusing my mind for a while. The Back EMF depends on magnetic flux according to Lenz's Law, if the magnetic flux is created as sinusoidal, the back EMF is derivated as sinusoidal as well. So my thought is that we can apply the FOC to BLDC motors due to the flux structure used in FOC Control Algorithm. Consequently, BLDC motors can have Sinusoidal Back EMF rather than Trapezoidal Back EMF.
Am I right or not. If you help me with that I would be grateful.
The back-EMF profile is determined by the way the windings of the stator are wound. For example, with trapezoidally wound windings we'll observe a trapezoidal back-EMF. In the literature and industry, there are examples of BLDC control with different control schemes such as trapezoidal, sinusoidal and field-oriented control (FOC). For better performance, the commutation type should match the back-EMF waveform. So BLDCs (with trapezoidal back-EMF profile) are recommended to be controlled with trapezoidal and PMSMs (with sinusoidal back-EMF profile) with sinusoidal commutation. FOC provides a better performance than both the trapezoidal and sinusoidal commutation but at the cost of being a more complex and expensive control method. Below is a helpful article summarizing different control schemes and comparing them to each other. I think your question is a great discussion topic for the Power Electronics Control Community (www.mathworks.com/matlabcentral/topics/power-electronics-control.html?q=&page=1). Please feel free to post it and any other potential questions you might have on power electronics to this community.

@@meldaulusoy8389 Thank you for your answer and interest! I am going to check and join these suggested communities. Additionally, I am waiting a lot more video contents like this, it is more informative and useful.
@@mehmetkilic9518 We're planning to have multiple videos in this series. We also have another video showing how to build the simulation model we use in this tech talk. Feel free to check it out here: th-cam.com/video/JDgvBZbnfPw/w-d-xo.html
@@meldaulusoy8389 Hi Melda, thank you for your comment, that explains a lot!
@@buraktufekci7345 Well, Both PMSM and BLDC need an inverter to invert a dc bus voltage to ac voltage in order to drive 3 phase BLDC or PMSM. However, lets see what if we couple two BLDC motor with their shaft, driving one of them using ESC and the other motor will run as a generator, isn't it. We have same idea until now. Observing the three phase connections of the other motor(generator) on the oscilloscope what you will see is a sinüsoidal voltage and it is the generated back emf. Look at the video below(start from 7.20) and tell me your opinion.

A very helpful vedio for me
Blese i want the line of the video to learn how to built the model
先赞再看～
Having fallen helplessly in love with this beautiful woman, I have now abandoned my search of understanding brushless motors.
can you help me please i have a searching project abt BLDC motors
laughing out loud
She is Turkish. Just a tip if you decide to find her somehow. Good luck on your quest my dear friend.
Having fallen helplessly in love with BLDC motors, I am wondering why I have to see this woman all through the video.
Simp alert🎉
Can a BLDC motor be controlled with an FOC controller ?
Melda hocam, yabancı dil bilmediğim halde anlatımınız harika, biz amatörler için aynı konularda Dilimizde yayın yapabilirmisiniz
Hoca türk ama alt yazılarda türkçe yok
Hocam Türklere cevap bile yazmiyor.Icimizdeki Bizanslilardan sanirim
Thanks for video!! Question: @8:53 you say to control the phases for the 6 step commutation a DC-AC inverter can be used. My questions is, can it be controlled using 3-phase variable-voltage-variable-frequency supply instead?
Typical motor drive includes an AC motor (BLDC in this case), inverter to convert DC source to AC waveforms, and a controller to control the operation.
3 commutations methods often used to control BLDC motors are 6-step commutation (trapezoidal), sinusoidal, and field-oriented control (vector control). In the next video we will look at six-step commutation.
If you are asking about V/f control scheme, that scheme is sometimes used to control induction machines, but is increasingly replaced by field-oriented control.
@@meldaulusoy8389 Thanks for taking your time to reply. I am teaching myself how to use Simulink and trying to use it to simulate a Ward-Leonard system (it functions as the variable frequency supply) for a test bed to test electric motors(PMSM, Induction, BLDC) for EVs. Will any of future videos be helpful in that regard?

Melda hocam,animasyonları biraz yavaşlatmanız mümkün mü
best video
Felicidades a las mujeres, ya era hora que empiecen a empartir clases, las mujeres desde niñas tienen esa capacidad de añy ser varias labores 👍
Nice explaination
And this beauty queen is also looking so lovely to me. Sorry to say
Hey can anyone please tell me how to add 4 teminals to the BLDC?
Mine BLDC has only two terminals
The circuit must be inside your motor. That 2 terminals may be for 24V and ground
This is for which course? Electrical engg or Mechanocal engg? Anyone can tell me the specific course/domain name?
I dont think this video was for a specific course, matlab just tends to post educational videos like this.
You would learn more about electric motors in an electrical engineering curriculum, though you will learn about them in a mechanical engineering curriculum incorporating circuits and mechatronics.
Both types of engineers can do research into electric motors, but mechanical engineers are more likely to be designing the mechanisms the motors actuate, and they will be the ones selecting which motors will be used, whereas electrical engineers will be likely designing the electrical components that manage and control power and signal to the motors, or track its position.
@@samo6401 but electrical characteristics of motor/generator is much more than mechanical characteristics, that's why much of the research and development in these devices have been from electrical engineers
Good
