How does the MGU-K work?

Having looked at the brakes, a lot of people wanted to know HOW the MGU-K slows the car down by adding to the rear wheel braking.
We'll look at:
- how the MGU-K turns electrical energy from the battery into power for the rear wheels
- how the MGU-K turns power from the spinning rear wheels back into electrical energy
- how MGU-K braking occurs
- how this all happens thanks to the interplay between electrical charge and magnetism!

Ok, I know you're all rushing to try and correct me and I know I do a very fast segue but: I don't say electrons flow positive to negative, i say *electric current* flows positive to negative, which it does. Models are set up using an old convention which uses the flow of positive charge, not negative charge. So, conventional current flows positive to negative. Electrons flow negative to positive.

[@ZwergofPhoenix]

Chain Bear F1 very good on explaining this but also you can't use the left hand rule because you need the movement of negative charge (you let the positive current move), you need the right hand rule to get the direction of forces then. Turns out to be the exact opposite.

[@chainbear]

it's not convention

[@SoYFooD2]

u envesize the fact that the generator slows the wheels down but not that it stors that energy in the battary.if u can envesize that u store the energy and release it later it will make more sense.so it looks like a brake and not a re-gen system.

[@jannga.shibefitti3162]

Can you do a whats faster f1 or rallycrosscars

[@abiedrashid3907]

Chain bear, your video is in affiliation with motorsport.com!!! That's the biggest racing website in the world!!!

[@Thumbsupurbum]

F1 commentators have been trying to explain this to people for 10 years. It took you 10 minutes.

[@wiryantirta]

Flintstoned because the commentators are no smarter than the audience in terms of engineering. Can’t explain what you’re not good at.

[@Bugi006]

Oh my god In a week's time I will have finished my second grade studies (university of technology, mechanics and construction of the machines) and I must say, you have explained principalities of motor/generator or electric/magnetic field linkage better and clearer than I've have ever read in a book or heard during lectures! Very good job 😉

[@rambopunk1989]

Bugi006 i was an electrical engineering major, and i can confirm this :)

[@heisenberg6442]

You gonna be a great F1 mechanic...Keep working hard👏

[@TheDareMaximus]

My god, 2 week ago in school we have lesson about electromagnetism and i told myself: "when I wiil need this in my life?" "this is so boring and why they teaching us this" Now i understand how the school is important, Great video, great explanation #RoadTo100k :)

[@yanisboussalah4226]

In general only stupid people think that we will never use what we learned in school.

[@Reydriel]

Dude, the "when will I ever use this in my life" way of thinking has always pissed me off. Knowledge is knowledge, man.

[@insanezombieman753]

Hmmmm.... I wonder why learning electromagnetism would be usefuul... Does it make my ceiling fan go around? Is it helpful in generating electricity? Is it the reason i am even able to type this comment?? NOPE its important cause its used in an mguk system in a fucking f1 car

[@Rad-88]

To me it's not that the learning of it is bad, i like learning new stuff, It's more that it counts to exams and you are judged on them even if aren't going to use it in whatever career you want to go to. I always hated how failing something as hard or complicated means you cannot progress with school for that.

[@gamernerd7139]

The rote education is the problem, not the knowledge. When you have great teachers that changes. But when a society values it money lenders and spin doctors more than its teachers, you know where it is headed!

[@McDaaniels]

You deserve so much more praise for your work. Good job at explaining everything!

[@paulodr33]

i'm not gonna pretend i understood everything but you sir, are making F1 more interesting to average fans like me

[@bombosen]

I feel kinda bad for teaching channels like u. Those Kind of channels should have so much more subs.. anyways, great explanations. Thanks a lot for that

[@josesammut9396]

MGUH Next?

[@mikosoft]

Same thing just coupled to turbo, not wheels.

[@chainbear]

at some point!

[@mellvanprakash7236]

It was explained in the hibrid engine clip

[@th1nk_outside]

if so please go in detail about the heat part

[@Chilukar]

This is what I want to see. This video is a great concise summary of what I already know. The MGU H on the other hand might as well be witchcraft. I have a vague image of a second turbo that powers a generator instead of an injector. But I have no idea if that is right or really dumb!

[@DanCMadsen]

As a hybrid certified Master Auto technician, this was a nice review of my daily work on Prius and other hybrids. Very well done.

[@TheAshleyYoyo]

I never understood Flemings rule in school and I almost failed physics but this ten minutes has taught me a hell of a lot! Love your animations - they’re so easy to understand. Awesome channel mate keep up the amazing work 🧡

[@ishanjasuja8213]

I just learnt the functioning of the electric motor in school. Very fascinating to see how it’s used in F1. Absolutely brilliant work!!

[@fbdiom]

This is the best explanation of a magnetic motor I have ever seen. Wonderful!

[@VGOM2000]

I wish there were more channels of such high quality on KZbin. Great video as always!

[@mhilmyfauzi4523]

Did you just inadvertently explained how the Formula E powertrain works?

[@Richard_AKL]

He just explained a motor and generator - I'm still waiting for something I don't already know. Video could have just said - it uses a motor to give power to the wheels under acceleration and uses the same motor as an alternator to charge the battery when under braking. Kinda like a Prius.

[@thiagoveloso7610]

I think he actually did it (and now I know why the battery and the motor need to be so damn huge in a F-E car)

[@thiagoveloso7610]

I think he actually did it (and now I know why the battery and the motor need to be so damn huge in a F-E car)

[@gordon1545]

I was just about to ask if this is how electric cars recharge from braking - thanks!

[@alexthegreat7518]

Probably

[@Angry_Squirrel555]

Very well explained. Granted this is all first year EE (and it does bring back some memories), but you presented it in a way that was very easy to understand for those not inclined in engineering.

[@starship_01]

Bring back the f***ing V12s. -Sebastian Vettel , Sochi 2019

[@bondmode]

and how is this relevant to this video in any way?

[@joshuasanford6934]

@@bondmode I thinks hes saying how complicated these things are and just wants the simpler V12s

[@GoodGuyGlen]

He wouldn't know how to drive one, given he didn't even drive a V10.

[@blasphem1a]

Another lovely day!

[@harshlahoti8368]

you, my friend, are not a f1 channel, you are a physics teacher who is better than my school teacher, thank you for that explanation of motors

[@johnrupesh4535]

Before this video was up, most people didn't know how an MGU-K works but now when this guys has put so much effort to explain things, everyone is an expert.

[@themagpie9able]

This is fantastically clearly explained. Well played, good Sir.

[@lunaticfae4415]

Youre videos are so good i know i can "like" them before the ads have even finished. Thank you for making such quality educational videos!

[@TheTobeyGaming]

Awesome explanation, as always! And the 3D animations look beautiful as well. Helps a lot to understand things i didn't even know i want to learn about :)

[@bennlowded]

I'm glad I found your channel. It's so informative. Keep up the good work! I love the channel

[@eljuetah]

dang man you explained how electric motors work better than most teachers or tutorials! thumbs up!

[@leonardantal6333]

Now that's what you call in-depth explanation video. Thanks and keep it up mate💪💪

[@harrykarmel4943]

Could have watched this video before my GCSE physics - literally the whole magnetism and motor topic right there. Great video!

[@KevinCrishan98]

Nice job explaining something that very complex!

[@alexmanuskin1276]

Celebrate every time there is a new ChainBear video!

[@doctorvortex7767]

I remember when I first learned that, I was like: “so if you shake a wire between two magnets you create electricity? Awesome!” But then discovered that’s pretty much how every power plant works.

[@johnpena8704]

Fantastic job, thank you for this wonderful and easily digestible information

[@DarkIron26]

these animations are superb! great job

[@FranciscoFRAO]

No thing to say more than PERFECT job man! Even if I understood it already you make me understand a lot more! Keep doing this mate!

[@fransisrld]

Amazing video man! Awesome job!

[@aeiouxs]

Great work, can see a lot of effort went into this - thanks.

[@IamSavageX]

I love your videos. You explain everything in way anyone can understand

[@puxa1874]

You make complicated things so simple! Thanks bro!

Favorite channel right now man keep up the great work, truly are a great youtuber and F1 fan!❤️

[@johnatancandaten5599]

Very well explained!! Good job!

[@TheJamaicankris]

Keep doing the good job you do buddy these videos are very informative

[@Vegeta101691]

Just got into F1 and this video is a god send. Thank you!

[@Itsraakunrandomit]

That's really a great and in depth video, good job! May I ask for part 2? I'm not sure if there's much information about this out there, but I'd like to see a simple explanation of the differences in this system between teams. Or atleast about the rules and restrictions to these kinds of systems; what COULD be done if the rules weren't as strict etc.. Also, how much does a system like this weigh and how much of a benefit does it give when compared to car without this system (that would therefore obviously be lighter) Thanks for all the work you do! Back in the day I asked for more in depth videos, and boy have you delivered! Also, love the fact that you are able to put out such great vids so regularly. Definetly my favourite F1 channel ;)

[@kusalperera8839]

Good video to explain the phenomena in very simple way. Thx

[@DOPYT1]

Amazing video yet again. I thought I knew how the MGU-K worked, but after seeing this video... NOW I know. :) Keep up the great work!

[@scullystie4389]

Wish I’d had this video in my basic electrical classes back in the day. Very clearly explained!

[@Josh-ui7nq]

Another really well put together educational video.

[@adri.gl3]

What a great explanation, well done man!

[@Jwoodman12345]

This is such a good video mate. I learnt a lot

[@samratsaha6029]

Awesome explanation, keep the good work going

[@gstephane1985]

Another simple but great video! Thank you!

[@rad8198]

Awesome job! I have really started to enjoy learning about F1 thanks to you!

[@10shatrunjay]

Can you do a video explaining all the buttons and dials on a modern F1 steering wheel?

[@sjonniedegangster9939]

Shatrunjay Pathare there is plenty of photos on this on the internet, plus it's just a lot of features for: the engine, tires, brakes, clutch it just keeps going like that. But definitely interesting tho

[@AlexNossib]

Don't want to advert another channel but I think WTF1 made a video with Renault reserve driver explaining the 2012 Lotus steering wheel with all it's functionalities. Go check it out if you're interested.

[@AlexNossib]

Name of the guy Jack Aitken reserve driver for Renault. They can't really show the newer steering wheel since they tend to keep that as a secret but you get the main functionalities of each knob/buttons wich didn't really change in the past seasons.

[@10shatrunjay]

Alexandre Bisson Yeah I watched that :)

[@TheBeardedAngler]

There are quite a few videos on it already and it’s definitely interesting! But we honestly won’t know exactly what the wheels button functions are due to team strategy and secrets, and driver preference.

[@shivanshmalonia6767]

Thanks you for reminding me of my school days. Lovely video.

[@nadhembouazizi7409]

Good job man, i appreciate your hard work.

[@tomyasch22]

I had this like 2 months ago on physics (the rule you visually presented). Now I finally get it.

[@rohandrummer]

Excellent!! I was always quizzed as to how does the car recover heat energy because that's what the commentators say most of the time, is that heat energy is somehow magically converted to electrical charge. Excellent video!!

[@andcunsan]

Those F1 engineers are very clever! Very nice video to use in Physics / Electromagnetic Classes.

[@tmmason10]

Such a good video and explanation!

[@anandsainath3108]

Excellent explaination.

[@greenshell4082]

Honestly, I'm still a little bit lost but I'm sure you're already making this simple as it is. Thank you for explaining this overly complicated MGU-K.

[@eagflc]

I'm new to watching F1 and love the sport. However there is so much I didn't know. Thanks to your channel I'm getting a grip to the sports mechanics. Thank you for sharing your knowledge to the rest of us less informed.

[@ryanrichardson6823]

While educating us you also managed a pretty cool optical illusion similar to the "which way is she spinning" ballerina. Top work!

[@johnrupesh4535]

Thank you so much once again. The explanation was perfect.
