Understanding Six-step Commutation for BLDC motors| Brushless Motor Control with Simulink, Part 2

- เผยแพร่เมื่อ 23 ก.ย. 2019
- In this video, you will learn how you can design a motor control algorithm for controlling the speed of a brushless DC (BLDC) motor. You’ll learn how different components of the system work, such as the six-step commutation logic or trapezoidal control and the three-phase inverter. We’ll also discuss why we observe ripples in the speed and torque responses of BLDC motors and give you intuition into the concept of inductive flyback.
The model used in this video is available in this GitHub repository: github.com/mathworks/Design-m...

I have actually never seen such a short precise explaination about Motor Control 👍
This is... this is honestly one of the most enjoyable videos I have ever had the privilege of enjoying. This entire series in incredible.
great job
We hope that a similar series is made about direct torque control of permanent magnet synchronous motor and focus on the latest research in this regard
This is complicated material to learn and review. That these videos are succinct makes it easy to watch a segment as many times as needed.
easy to understand and clear explanation ! nice !
Clear and interesting. Bravo!
I cannot wait to watch the next episode !!!
Hey can anyone please tell me how to add 4 teminals to the BLDC?
Mine BLDC has only two terminals
This is really amazing and damn good explanation. Thanks a lot
This is a very good tutorial!
Tebrikler Melda! Acik ve net bir seri....
Nice work
Thank you very much
Good explanation!!!!! Love you, in a healthy way !!!
very nice! the narrator is very beautiful
If we are using a fuzzy controller then which one has more advantage compared to ur model??
In the case of electric vehicle the motor acts as a generator, it produces kinetic energy, and I need this energy back to the battery for charging it(Regenerative braking system). I don't understand how to the inverter work when the motor act as a generator?
Ne güzel anlattınız,birde sizi anlayabilsem
Alt yazıları aç ordan sözlükten bakarak anlarsın hacı eger bldc motor sürücü yapacaksan toshıba nın sürücü entegrelerini tavsiye ederim ben onlarla çalışmaya başladım aslında on semiconductorla rohm da iyiydi ama toshiba güzel st ile microchip işi abartmışlar gereksiz ce entegreyi kompleksleştrmişler pahalandırmışlar
Excellent video, Melda!
At the end of the video you mention PWM will be introduced in the next video. Has the next video been created? If yes, what is the link? Thanks.
The video on PWM control has been recently published. Please find it here: That video has been posted recently. Please find it here:
@@meldaulusoy8389 Do we actually need a back emf if we replace a bldc motor I mean does the back emf needs to be implemented if we make the equivalant circuit, i try to test the motorcontrollers current and will measure if the commutation is going the right direction when controlling it, but does back emf have a lot of effect or can i ignore the back emf when realizing the back emf?

Very important video
Good job
Excellent. . . ..thank a lot for your greath tutorial

wow . . . such an informative and helpful explanation
Glad it was helpful!
Very good
Can anybody answer this one? When I was scrapping, I came across what looked like a brushless motor for an AC fan instead of an induction motor. What's the point of that? Don't the AC fans only need to spin 1 way???
I have a question here. It's said in this video that to vary the speed we need to vary the DC supply voltage to the inverter. So instead of varying the DC supply if we change the switching speed of commutation in that case also we can achieve a faster or slower speed. Isn't it?
Thank you🌹
Good job. Similarly please provide a closed loop operation of induction motor drive.

Hi first of all your art is absolutely stunning 🤩,second, happy to watch!😛👍🍭😜👍beautiful artwork dear full watched 😍💞💞
Astonishingly beautiful!!!... What a brilliant masterpiece!!!... Your artwork is phenomenal! Your skill set is superb with amazing techniques!!!... Awesome creations! Absolutely love it !

make a new friend just amazing no wordssss..💌💌💚❣️💛💕❤️🧡🧡so beautiful work really enjoy by watching your video keep sharing stay safe and connected🙂🤗👍🍂🌷😛🍖🌹❤️🧡🤣💟💜💛💙🧡🧡❤️🧡🤣💟
The fourth simulink model can not be run with MATLAB R2021a version, how can I solve the problem? Thanks!!
that's great!!
Please give me Simulink diagram of BLDC Motor
For sequence with only positive speed values i am getting correct results
But Can someone tell me why after input sequence as first +ve speed then -ve speed is not giving desired results?
how make motor spin in reverse direction?
Can we see a similar video for four phase? Wouldn't 4 phase be a better choice for electric vehicles as there would always be power applied to a coil leg. Would this create more power to size in electric vehicles?
Real BLDC motors are delta wired instead of Y wired, so they don't actually have this issue, Y wiring is easier to demonstrate I guess?
Can I expect the same efficiency in both directions of a Sensorless motor without having to reset or reprogram a basic rc esc? Simply put, can I expect the same efficiency by simply switching 2 of the 3 motor wires? Thanks
Yes
Please let me know that videos of model
So...... Beautiful

simp alert!
This is for which course? Electrical engg or Mechanocal engg? Anyone can tell me the specific course/domain name?
Definitely, this is for electrical engineering. This was taught under the Electrical machine module in my course. But, these things could be appeared under mechanical engineering
😀
NICE i SUB YOU
