Amazing videos jantzen truly! Although, I have one remaining question: how do we understand the connection between the PWM switching pattern you show here and the alternate reverse SVM waveforms that we are trying to create? How is it that this exact form of PWM switching creates those funky voltage waveforms we need (perhaps you could connect this with the SVM 6 vector hexagon as well) ? Thank you

Subscribed. Waiting for more videos 😊

Wheres 15?? :)😊

Hey, Great video, I'm very impressed with you knowledge for the subject matter. But I think you missed injecting a third harmonic in the PWM sequence, the triangle wave and it's implementation is missing from your software scope. It's dependent on the angle of the magnetic field vector and based on that we will either add to the voltage vector or subtract to it on the positive and negative sides. If you address this in a future video it'll help put a complete closure to this series, which I believe is the best one out there. Kind Regards

i have problem understanding why we still using Sectors while we have a SPWM technique, i mean we got rid of the ripple and we can get the exact current just by the angle ( sensor ), why did we use the sectors that are for 6 and 12 commutation blocks, because i totally lost it when you entered the T0 T1 T2

Your videos are amazing! usually videos with good animation and great writing often have less details, and are overviews, but yours have very dense information. So much in fact that these are a great resource for motor design!

Well, now I'm curious if this is the reason why Tesla doesn't use a blended pedal. Hmm... It's really difficult to find good information on that sort of thing. You'd think, if this were the case, they would put it out there to be known, saying, "Yes, other manufacturers use a blended brake pedal so it's logical to assume that leads to greater efficiency, however, here's the science and reality..."

I just watched five videos straight and I figured I should periodically stop, take a deep breath, and leave an affirmative comment. Dude this freakin' rules 🤘 As somebody who has recent memory of thinking that stepper motors were complicated, and as somebody who just started screwing around with Simple FOC, this was the video series I needed to make it make sense. Thank you. Fun fact: it took me longer to figure out how Tig welding actually worked on RUclips than it did to learn how FOC control of brushless motors works. That's amazing how efficiently you deliver that understanding.

Here from the simpleFOC discord- great video

why do we apply triangle wave? because its simpler than sine? it should be 1/3 in amplitude? its basically a third harmonic?

🎉🎉

May I ask what does the 'M 1:2' mean, which is in Maxon Datasheet's Electro-Mechanical characteristics?

Hey bro. Ty by all. I don´t speak inglish and can´t traduction this video because the lenguaje is in rusian. If you coul change the lenguaje, please.

Thank you for excellent videos!

Capturing the currnet in a loop was real something 😂

This is called ART <3 Truly fascinating series

So how do you actually calculate the power coming out of the battery then?

bro where are you only one playlist the world deserves people like you please come back and do more videos its my humble request. oh god you're great man and this is the end of this playlist

good explanation 👍

uh is this more true for teslas with their non magnet motors? around town in my volt with master race rare earth magnets i regularly get 5-7 miles/kwh. feels like i dont have all these efficeincys and fet switching trickery, its just a magnet spinning...

Taught everyone your profession ? Lost your job ?

after watching a lot of later parts of this series, the sentence "PhD in Mechanical Engineering" was not one I was expecting

I got into 4 minutes & gave up.

Thanks for making these videos, they are quite informative 👍 One Question: Torque is produced by the force generated by the interaction of Magnet's Magnetic feild & current flowing through the Copper wires (I.B.L.Sin(theta), Amperes Law). Back EMF is produced due to rate of change in Flux from PM of Rotor. how does the energy associated with I.BEMF equals the energy produced ?

If I had watched this video before my interview, I could have probably cracked it. The current flow direction, magnetic field direction and torque direction you explained at the start could’ve saved me. :)

Guve us the relation between speed and communication 's frequeuncy

Why do we need to use V0 and V7 what happens if i remove them. Line must be V1 - V2 - V1 - V2 - V3 - V4 - ....... And i wanna say, that's a great explanation sir, thanks for your video

I like your illustrations, especially the ones that those that are dynamic. What software do you use?

Sacred words: "..., however it turns out that a lot of what's on the Internet is well less than accurate and it's not always easy to tell the difference between someone who actually knows what they're talking about and someone who just thinks they know what they're talking about."

Subscribed just because your explanations are simple and clear, with just enough background information

What does the number of pole pairs mean? I suppose it correspond to the number of windings divided by 3. But at the same time people speak about the number of the rotor poles. Some times we may have 12 windings and 10 poes in rotor. So, how many pairs of poles do we have there? 12/3 = 4 or 10/2 = 5?

This is a great play list. Is it possible to translate it to the other laguages?

Make some new videos, your stuff is great!

That moment when you are speachless to say just thanks ... wow man no words can describe how much grateful iam

i don't make sense of force vector leading our current vector by 90°, at this point given the conversion sin(90+θ)=cos(θ), i can guess these come to ildbcos(θ) ， please give some explaination here.

This series is amazing. I can't believe there's such a high-quality well-explained series that goes into such detail on this topic

I was trying to charge a battery by running on a treadmill. This is exactly what I was looking for. Thanx

First or all, a big thanks For this series which goes deeply into the physics concepts of electromagnetism underlying the workings behind motors and with clear and deep explanations !

Can't believe this gold has been out of my subscriptions list until now. Awesome content, you manage to detail the matter without extending too long the video!

Does the experiment at 7:30 apply also to a 3-phase motor, or is it not so simple and intuitive there?

My mind is truly blown by the level of clarity and simplicity in the content you're offering. Your ability to break down complex topics into such easily understandable explanations is a rare gift. Thank you for making learning so accessible and enjoyable!

I truly appreciate your extraordinary work in teaching us these principles seamlessly. Your dedication to delivering complex concepts in such a clear and approachable manner is truly invaluable. Thank you for making learning such a challenging topic so enjoyable and understandable

I wanted to take a moment to express my deepest gratitude for the invaluable guidance and enlightening content you provide on your RUclips channel. Your exceptional ability to simplify complex topics, particularly electrical motors and control, has made a profound impact on my understanding. Your clarity and simplicity in illustrating such intricate subject matter have not only enhanced my knowledge but also sparked a newfound passion for the field. Your dedication to sharing knowledge and expertise in such an approachable manner is truly commendable and inspiring. Your videos have been instrumental in helping me navigate through what initially seemed like a daunting topic, and for that, I am sincerely grateful. Thank you for being a beacon of knowledge and empowerment in the realm of electrical engineering. Your work has undoubtedly made a positive difference in my learning journey and has left an indelible mark on my pursuit of understanding electrical motors and control.

wow, what a video

The diagrams in this are great visualizations of the concepts. Very creative, thank you

Love from India <3

Now I see why linear algebra is useful 😄

so cute you are
