Do you like the small animations in the video or do you prefer my hand drawn style? Let me know! Comment from : GreatScott!

Муха - это маленькая птичка Comment from : with you

Hello, please tell me that using the FOC option replaces the need to use Gearbox? Comment from : Shlomi Ben Yair

FOC Control of 3D printed Brushless Motor br youtube/gLDUQX1zxV8 Comment from : 3eng

I come back to this video at least once or twice a year Thanks for making this Comment from : Felix Man

Is field of control neccessary/beneficial for stepper motors? Comment from : Ryan Mckenna

Of all the FOC explainers on here , yours is by far the most enlightening THANKS! Comment from : P R

Dude, you really need to fix your f@cking pronunciation and grammar Comment from : csengo70

I didnt know you have this video TT thank youuu Comment from : Christian Acar

Need to work on your "field" pernounciation Comment from : 2D Weather Sandbox (Niels Daemen)

What the foc!? Comment from : Salvatore Cipolla

Wow!!!! Excellent video here!!! Wow! Such detail and attention was made here I like the animations due to the fact that everything can be seen in movement or at least propagation Keep up the amazing and ever improving job! Comment from : Anthony Volkman

There are 8 combinations Not six 2*2*2 Comment from : x_ma_ryu_x

Can you used that to control salvage ac motors from EV? Comment from : Andrzej Obama

Always great! Comment from : K E

What if you don't give a FOC? Comment from : TheRoon4660

This reminds me microstepping for stepper motors Good video! Comment from : AceMasterX

Does it depend on the rotary encoding or can it also derive it purely from current sensing? Comment from : Bernd Eckenfels

What motor donyou use in this vid? Looks liike a good candidate for my next project Comment from : sander veenman

What the FOC? Comment from : Toot Nugget

Please review MCF8316 (FOC commutation) and MCT8316 (Trapezoidal commutation) from TI Comment from : Rishabh Jain

wtf?!?! Comment from : Dinitha Lakmina Wickramasinghe

perfect explanation 👍 Thank you so much Comment from : Jawad Ahmad

How does zero-crossing detection on floating wire factor in here (if there is no floating wire)? Is it even needed here? How do you limit current and do sensorless driving if there are no floating wires? Comment from : osmanpashas DIY

Very interesting Comment from : James Barclay

Amazing video! Comment from : f reak

GOOD ANIMATIONS Comment from : o o

FML I want that scope :( Comment from : PatentLobster

So I can understand that FOC is like what Active PF correction is to utility supply except that here there are THREE continuously varying parameters to control& trackbr1) desired motor speed / velocity & it's flux field& motor electrical frequencybr2) current/ torque/( mta)brmax torque per ampbr3) so some what a current waveshape profile that's demanded by flux field & frequencybrAm I correct?? Comment from : analoghardwaretops

Awesome video tutorial however There is a difference between BLDC and Permanent magnet synchronous motor PMSM FOC is used for PMSM control Comment from : Omondi douglas

what the FOC Comment from : alex van rijswijk

why the subtitles are in holland? Comment from : Leone Venticinque

Hi, Scott! What is field weakening? Is it related to FOC? (Maybe a video idea?) Comment from : jhsevs

8:00 I thought my ears were playin😂 Comment from : Aayush Bhansali

0:35 Муха :D Comment from : Иван

VESC is waayyy more versatile and customisable They also use components that are vastly more popular and arguably perform better than trinamic ASICs And jeez the cost If you don't want to tinker with your electronics or don't understand it, go for trinamic motion In any other case VESC is a clear winner, they also do have a sensorless FOC Also FOC may not be necessary for your application, understand why it floats on the market before diving into it brbrThis is my opinion, you can disagree Yes, I'm Indian, but please keep the racist slurs to you if you are planning to throw them Comment from : Anubhav Mukherjee

🇾🇪🤪🤪🤪🤪🤪🤪🤪🤪🤪 Comment from : Arko

Please make a video about making Power stages which can be used with different motor control circuitry Comment from : Aravinth KJ

great work! brcan you please do a simulation for a three-phase induction motor variable speed drive using FOC? Comment from : sihle jz

Great as always! Comment from : Lazy Man

@GreatScott! like your video a lot think you have load of experienceI replaced the the molten down 1kw brushed my1020 Motor with a 80100 outrunner (sensorless :C) in my forca evoking scooter I am almost sure that it is not worth to try running it with my 14S120Amp RC motorcontrollerso i wait for a VESC42 i decided U think this will propperly accelerate ? Comment from : RA1-EULE eULe85

good one no fake or fuck news TOP Comment from : RA1-EULE eULe85

What about Texas Instruments Instaspin? Comment from : Kerbal Launcher

@5:62 PWM "voltages" - wrong word - you meant current, but that's still wrong too - "PWM duty cycle" is what you meant @1:27 - beautiful scope trace @3:29 - garbage; if you're going to compare "old" with "something you got sponsored to talk about" you should do a fair comparison and put equal effort into showing properly gathered traces of reality We don't mind you selling stuff We do mind when you're dishonest about it Comment from : Chris Drake

Can you plz change your channel's introduction like when u make a pcb of your channel's name , I am really bored with that Comment from : Madhav Khandelwal

I'd rather not advice the people trying to learn how ESC work to buy a proprietary IC & forget about this knowledge Comment from : Angel G

The word “FIELD” is pronounced like FEELD Comment from : Bruce Woods

FOC in Românian language , mean “fire” in english Comment from : Alex C

How about the A89301 sensorless FOC controller from Allegro?brbrI like to see a DIY project of BLDC motor controll With that ic it might be simple enough Comment from : SV Vela Nautica

Can you publish a book with your projects? with reference to your videos Comment from : judgenap

I bet the biggest paper waste comes from this channel xD Comment from : AmeliaBuns

Superb I learnt a lot of things Comment from : SARBAJIT DAS

0:36 Filed Oriented Control :P Comment from : ManMadeDesaster

I know what FOC is It means f**k😂😂😂😂😂😂😂😂😂😂😂😂 Comment from : Anyfinity Abrar

This is dtc Comment from : Wojciech Wojtowicz

what the foc? Comment from : Steve

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 Comment from : Chittling Whittles

Can I get the model board name? Do you do the video for back zero-crossing position emf for the bldc using this foc board? Comment from : Billy Chang

Why do 3 phase motors use dc current injection on some vsds Comment from : Chris Shand

Great video! Do you plan on making a video on BLDC motors using the ODrive? That would be really cool :) Comment from : Cristian Talos

How big ist the efficiency Gain by useing FOC ? Comment from : En1gm 4A

That is a very nice chip, though I think going a diy PCB would be interesting, the QFN76 package is 115mm by 65mm and 76 pins!!! Not for the faint hearted I believe the TMC4671 breakout board is 4 layer, adding more cost and complexiy to any hopes of DIY, maybe I'm too old haha Comment from : epineh

Here in my company, we use this tmc ic For stepper motors we use tmc5160 It's really great Comment from : Akshay Das MK

Trinamic is an awesome solution Comment from : IOTON

Would one of these boards be a start of a good ebike controller? Comment from : JAMES T

How da foc! Comment from : JAMES T

Good day everybody, I'm looking for english version of the first paper linked "Feldorientierte Regelung der permanenterregtenSynchronmaschine ohne Lagegeber f ̈ur den gesamtenDrehzahlbereich bis zum Stillstand" by Héctor Daniel Perassi If anybody stumbles with this and knows of a translated version, I would appreciate a lot if you let me know brThank you Comment from : Hairyneko

What da foc is dat Comment from : fuehwbdb

Can you add FOC to your DIY esc? Comment from : NilsM99 NilsM99

Is that possible to make speedometer in small for cycling and motor rev and make a scooter that is powered by lithium battery bldc motor with gearbox in 6speed manual Comment from : murugasen ram

Could you post a video on Direct Torque Control (DTC) Comment from : dennis stanlee

The problem with FOC is how you have to fiddle with settings when motor parameters or load changesbrFiddling with settings is annoying at best and rage-inducing at worst Comment from : 1kreature

So, impulse generated in coil by oncoming magnet, while coils is still energized is capable as sonusoidal wave to ga back thru the wires, small resistor, attach it on input pin (ARDUINOOOOOOO) bit of clever programming (or just and voila you got your self a very nice ( programmable even) BLDC controller brField Oriented Control clever name, that is for sure :D Comment from : Igor Stojanovic

i had my project on collage about foc, the interesting part about Foc is, you need to model your controller with stator rotor impefances, it impacts speed and position control massively I had a detailed project and matlab models about it on collage, i can share anyone who is interested Comment from : sinhusoidal

Can these be used to fine control stepper motors? Comment from : Michael Bishop

Atul Vinayak br4 months ago said:brYou wasted an opportunity to title the video "What the FOC!" I say you took the opportunity to be clean, GOOD! I like the fact that your speech is clean, so many of us can watch and learn without getting morally debased Comment from : TheBdd4

How many hours does it take you to make such amazing videos? Don't you get tired from time to time? Btw great content! Comment from : Meru Gr

is it simmilar to 3-Phase induction motor controller? Comment from : Ferdiand Cornelius

Can you explain how implement the FOC technique in closed loop bipolar stepper motors? Comment from : Davide Bressana

Omg 😮 I was trying to find a video I watched about latest Bldc driver controllers but can’t seem to find it and thought I must have dreamt it ! But lucky I find your video that proves better driver tech is real I wish I could find other video though as it explained certain things that I want to research further and I think you may like it I just bought aeg fusion drill and it has latest Bldc motor controller which nearly doubles it torque from 70 nm to 140nm I also uses Panasonic 2070 cells instead of 18650 Very powerful drill Comment from : Energy Storage Developers

Stay creative and I will see you next time Comment from : kamal Kumar

a video without jlcpcb!!! Comment from : Clickbait

This Trinamic IC isn't very plug n play system Tons of registers to set before you make any sense of it It lacks auto recognition of the motor, so all parameters needs to be put by hand Texas and ST are making real plug n play chips since they have implemented real time auto tune feature for all critical parameters from the motor Comment from : Suharinos

Secret drone project ;) Comment from : Mitchell Cottam

the video was perfect but FOC needs a resolver or encoder and this is bad news for hub motors i thinkbr FOC just turns normal bldc motor to industrial servo motor brthe question is : do we can implement FOC for the hub motor (normal one) or even for small bldc motor(like in the quad copter ) ? Comment from : Ayman Essam

Thanks for super understandable video (y) Comment from : Muhammed Yaşar KAYA
