I'm 63 but I feel like 6, as every morning seems like Christmas with a new gift from Sandy.
I was thinking the same thing at the start of this series --- feels like Christmas! I'm grateful for Sandy.
I’m only 41 (who am I kidding?) but it feels exactly the same! This man is like a walking encyclopedia. I would live to work for him even by brewing him coffee every morning. Just being there and looking at all these amazing things.
As a 41 I would told my 15 years old self to learn how it all works so I can see all the pros and cons of each design.
@Joe Kinchicken You can either bring joy and light to the world or ugliness and hate. Your choice.
I've been a Macintosh consultant for 27 years so I know something about technology. The Model 3 has THE lowest rate of depreciation rate of any car at 5.5%.
EVs cost about a third for fuel per mile compared to an ICE vehicle. EV maintenance is next to nothing compared to an ICE vehicle which by comparison is a Rube Goldberg machine. Go look up Rube Goldberg as you're obviously rather ignorant and wouldn't get the reference, grasshopper.
@@martingardens on the other side if there was a competition between Tesla model 3 and BMW M3 in circuit tracks before there isn't anymore due to track mode v2 uodate. Tesla is now both faster and more fun to drive. You don't have to believe it but once this virus thing is over and all the tests can resume this will become apparent :D
Feel free to add ads. Got to earn your money for your hard work in these times.
Second this idea. $3-5K per million views.
@@teslaxyz4660 He doe's not have enough subs to get any real money the auction good idea.
@@netgeek3010 You dumb? The channel already has almost 1,5 million views.. You go and try to do the same within two weeks. Automotive ads used to pay a lot - now all the ads I get on TH-cam are from "digital nomands"
@@rkan2 Really, he should solicit ad deals like autoline, direct ad deals are worth way more.
Patrick O Yes. The autoline inline ads, short, to the point, are the way to go.
I would say everyone likes listening to Sandy as if it was quite literally your own uncle explaining everything about mechanical stuff. It really is that cool!
Also, stay safe and keep those allergies taken care of.
I agree definitely hope this channel gets bigger.
I was not expecting that much variation in the electric motor designs, just wow.
It tells you that things are evolving if we look at combustion engines they're all fundamentally the same aside from wankells because there is a sort of agreement on what is working and isn't working for maximum efficency with a combustion engine.
They are all the same jus two main types induction and pm just like diesel and petrol
You would be surprised
Online training classes would be interesting too.
I had the same thoughts ;)
Just missing the great chance to meet Sandy in person...
Yeah, I'm not paying $87000 for a class but I sure would pay $100 for a couple hours of detail on components, especially electronics and wiring for Model 3!
Yes!
This is a really good idea, classes that focus on post grad engineering topics like, how to setup designs for fabrication, best practices and such.
Great Idea! Remote seminars/classes.
Those videos are addicting. I could watch like 100 episodes in a row. Great work!
Jarosław Krzyżanowski Exactly the same, strangely very watchable. It’s not like someone instructing you more like a friend showing you round his new Car, very relaxing. I know more about the model Y than I do my own Car now😀.
Every episode is amazing to watch but this one stands out when we get to see different approach the car manufacturers takes to make the own power train. Thx Mr. Munro.
Not hokey! Do what ya gotta do to keep the doors open. Love these Tesla videos! Great way to sit down in the morning and have some breakfast with something relevant to watch towards my investment in TSLA. Thanks Monroe, video guy and editor!
Brandon Smith why do you call it Tesla videos?? It’s not exclusive afaik - checkout the technology of other manufacturers like Mercedes you will see that they make a really good job and earlier than Tesla started to build cars 15 years ago but 100 years already
Sandy. Excellent video once again. Revenue ideas,, Shirts, hoodies, coffee cups, engineering break down prints limited ed. Why, it works
Merch should depict "exploded" engineering diagrams of interesting (Novel + Awesome + Tesla (Anything Tesla specific comes ready made with a legion of slavering fan nerds (like me))) subsystems.
Ideas:
Tesla regenerative braking system - depicts and calls out the "magical" components. Anything with question marks where a descriptor or explanation should be will provide an air of mystery and awesomeness.
Tesla Induction Motors: show an exploded diagram of how the rotor magnet is made of of all those laminated layers - include prominent callouts for the mysterious components. Annotate interesting things with US patent numbers. (geeks love that shit)
Tesla battery management system:
Tesla FSD computer circuit (mother) board: label the prominent items: RAM, GPUS, DATA BUS, CPU(s), block out the redundancy-ness (Thing 1 and Thing 2)
Overall the Munro mystique is that you plumb the magical depths of automotive manufacturing tech. Play up the mysteriousness of this in your merch.
Might work for other carmakers' stuff too. I've heard there are other carmakers, though i personally pay exactly zero attention to any of them.
I'm a technologist, not a paleontologist.
@@johnalley8397 can't do that without infringing upon Tesla's IP rights. TH-cam is fine because it's fair use, and selling parts, is a standard sale. They would get in trouble making Tesla branded merch. They can do their own Munro merch though
He has this kind of lab which I wonder every student dream to learn from. Every day I wait to see his notification and learn something new.
This sort of detailed explanation from someone qualified to give such an explanation, just isn’t available from anywhere else. Keep it up Sandy. Auction is a great idea.
The Collector’s Model 3/Y Cocktail Wheel-Table seems like a great idea Sandy! Keep on coming up with these interesting ideas for products from your shop. Thanks again for the amazing content/knowledge that accompanies these tear downs!
Agreed.. anything cool you guys think up to do with the parts, is a good idea
4:29 "They stick like... well, I can't not use that expression, but they stick really well " :-)
Sandy,make a tshirt with that phrase on it. Sell it fir $15-20, . That,is $10 profit
So what is the phrase?
@@mcplutt "They stick like ....well..."
I have a few ideas.... crabs, dui's or gold diggers. I'm going with like Mud or Cherry scented lip stick. Mud is a reference to "treat them like dirt, they stick like mud" or Jack Off Jill - Cherry Scented Lipstick... "turn that tattoo into a bruise."
Like shit to a blanket
Mr Munro, if I commented on the coughing it is only because I was worried for you!
As for suggestions: you could open a patreon account. A LOT of youtubers use that as a source of income.
Thank you for the video series, it is a goldmine of information. Kind regards;
EDIT:
i just saw you opened one already
, good explanation to (cough) not (coouuugh... aaarh... grhmmm, uh) no conspiracy here... ;-)
, people see that covid -guy behind every "cough" corner and it feels allmost like joke , what it is not.
Kampela99 : I wondered whether Sandy was a smoker.. . I hope not.
Lol. I was just going to let you know about their Patreon. 👍
They should put 1 or 2 ads I'd still watch with an ad in the video 🤔
I will contribute to a Patreon account for Sandy!
Mr. Munro, the neatness & cleanliness of your shop speaks volumes about your company. This is an owner that cares.
3:48 "The magnets are pretty strong so you try not to get watches close to them"
*_Camera gets closer towards the strong magnets_*
Perhaps, they just zoomed in !?
@@papytrad8915 /r/wooosh :P
Modern camera will not get affected I have worked on MRI and use my phone right next to it.
Well, it is attracted to them obviously :D
@@theAppleWizz hehe.. MRI is not that strong.. Real magnets would probably break at least the displays on phones, or maybe not.
Only guy that actually shows you real stuff about cars.
Im an Electrical Engineer and i would pay for a MasterClass with Sandy Munro....plus where are this auctions?
We definitely need to know all about the gear oil.
Isn't it ATF oil?
Hey Sandy,
do manufacturers normally have a closed system? I am quite surprised there is an oil filter - I would assume you never change it like a differential or gearbox once or two a lifetime
@@accountname1651 It will probably last a long time, but in a gearbox, small pieces of metal filings come off from gears and bearings over time. These need to be removed or it will turn the oil more and more into grinding paste, accelerating the wear. Normally it is a closed system. On some truck gearboxes, they use magnets at the bottom to collect the metal filings, but that would only work if all materials used are ferromagnetic.
Aaron Bounds it also means a pump as well to push it thur the filter
@@andydelarue9344 There could be a pump just like in an automatic transmission.
Munro can you show the inside of the heat Pump?
We'll absolutely get there, yes. Thanks for tuning in!
@@MunroLive Absolutly interested in details of the heat pump ! :)
Ditto!
This man has done incredible videos about EVs . Very impressed power of knowledge....Hope Tesla and other brands are watching him to learn from his advices and expertise. What a personal pleasure hearing him explain all of this. Thank you so much.
MaxKito2 it’s so crazy to read comments like this - I have the same job like Sandy does to improve prototypes of a car manufacture in Germany
have you never thought why it takes 3-5 years to develop a new model? that companies do this internally without any video and you buy a already improved product?
Chris Andy dude relax....all I say was thanking that man making a good video explaining the ins and outs of the car. So for you to say that is crazy to hear comments like this, what exactly are you implying? Most people here watching these sort of videos, are not experts in a way, and we don’t have to be experts, this is a TH-cam channel where everyone is welcome to participate and learn and they too appreciate seeing someone taking their time in creating videos like this for us all to learn. I don’t see a problem on that and no one here needs to be an expert in order to express an opinion, so what exactly is your problem? Just saying
Sandy, you can harrumph any time! LOL
What the heck??? This channel is pure gold! I'm very glad TH-cam brought me here. It's been a long time since I've seen such pure distilled engineering analysis like this! Thanks so much Sandy!!
For my birthday I want to spend the day touring your facility and hearing about the nitty gritty differences between these motors.
Good idea. A few things I would like to see in America if I ever got there would be the Reno Air races, Jay Leno's car collection, the Smithsonian and Sandy Munro's facility. All on my bucket list! Could die happy after that little lot.
I just wanted to thank you for all your videos and let you know that I freaking LOVE this channel!
Keep up the great work!
Loved the electric motor explanation part! Hope you get a ton of subscribers!
"o well cant use that expression".. Love watching just how down to earth and always learning a bunch
Thank you
Sandy, your the best! I love watching your videos and check multiple times throughout the day hoping for new ones. Great work!!!
Great work again, very interesting tear down. I think it would be very fair if you put up 1 commercial at the beginning to get some compensation for your work.
you can also support them on patreon, if you want to. just have a look into the video description.
Sandy, These videos are terrific. Thank you for sharing. The long term value that these will bring your business should be off the charts.
more on motors please. Thanks for the upload.
Great videos Sandy! Thank you for your efforts!
This is the best channel on TH-cam! Thanks Sandy.
Sandy just herumphing and we’ll keep watching.
I’m down for the “Welcome back, boys and girls” T-shirt in XL, XXL and “Michigan.”
The mitten & rabbit !
You are doing a great job, Sandy. Keep it up. The auctions are a fantastic idea too. Thanks for sharing with us!
Never have I enjoyed so much what I understood so little.
Thanks so much for making these videos, Sandy and team. Stay safe!
I love this series of videos, good content✌
Awesome work Sandy. Keep it up. The auctions are a great idea. I hope all the car companies sincerely appreciate everything you do. This drives everyone to be better.
Sandy, it is amazing you can pack all that detailed information in a single take without errors or flubs.
Thanks for all your great work in this area Sandy. You are the David Attenborough of the EV Deep Dive, Sir!
I hope the community can come together and help ensure you can keep the doors open! Fantastic ideas with the auction pieces!
All the best, and stay safe!
Sandy - Keep this up, these videos are great! Thanks for doing this.
Loving the content, thanks for the efforts
Great idea for the auction!
Thank you for showing us this. I'm no mechanic I can do simple things but it does show me stuff that I would most never get the opportunity to see in my lifetime.
1:15 Sandy, I think that PM motor has a special rotor geometry to allow for field weakening. You can see a quite thick zone on the laminates between the magnets compared to other PM designs. Field weakening allows for greater top speed. In a PM motor this is done by playing with the stators field angle relative to PM rotor's field. By making the winding's field go not straight through the magnets, but some of it also bypassed through the iron, you affect the global field. Switched reluctance motors are doing something similar but here I think the goals is field weakening for better top speed. Thumbs up for Tesla!👍 And thanks Sandy for the great videos, keep them coming!
You should consider monetizing your videos to make extra income. We would not mind commercial here or there. Thank you for the excellent content and fantastic insights.
We have submitted for monetization, we are currently in a waiting period. Thanks for tuning in!
Munro Live sandy keep in mind, don’t mention the virus or you will lose the monetization! You’ve got to use code words.
@@bob15479 I'm not certain, but didn't TH-cam recently change policy again? Permitting monetization of pandemic-related content?
@@Urgelt I would say avoiding using certain key words in the title (and description) is still a safe measure to avoid demonetization. That of course comprises a lot of non-corona related terms and whatnot.
@@bob15479 like donout-19? :D
You had me at 'oil squirters'
Many thanks for doing these videos !
Love the comparative deep dives you do on the technology.
This is like a masterclass.
Table looks great. Keep up the good work! Thank you.
love all these videos, but I also love to see all types of engineering and design... i could learn about electric motors all day!
Great electric motor comparison. Thank you for the great content! 👍🏻
Awesome job guys love these longer videos 🙋♂️😎! I actually love the high table top made from model Y wheels. You can in addition put in 1 or 2 adds in your video's. Some channels make 100k plus a year on ads I believe you videos need to all be over 10 minutes as well.
"Brilliance of Tesla" I like that slogan. Thank you so much for such an in depth analysis. Your videos are the only ones I have been looking for to these days.
finally a great content about interesting stuff for me ... big tnx
I really appreciate your no BS approach, Sandy. And thanks for the cashier tip idea. I did it yesterday and it felt great! Gotta do it again. Jess
Very good idea! Awesome videos as always too
Another one wonderful video. Thank you!!!
Very educational! Thank you sir!
Always looking forward to daily munro dose of knowhow
Thanks Sandy! Learned a lot.
Yay! More Sandy Munro!
LOVE the tire stand! Great idea.
Ahhh, my daily Sandy fix!
Awesome work!
If you need money you should make merchandise. If you ran a design competition you would get some great ideas to use.
As Yogurt said in Space Balls, “The real money is in the moichendice!”. Go for it!
@@stevewaclo167 shoot, Elon responded to them, that should be worth a dollar or two of t-shirts; everyone and their grandma's doing it these days.
As long as Elon/Tesla don't object, that is.
sandy with a cape = disassembly man
Sandy, you teach me so much about car technologies. I can teach you a bit about allergies:
Google the Butekyo method. There are many resources, but www dot normalbreathing dot com (no affiliation) is one of the most comprehensive. Modern man is breathing faster than a century ago. (More stress, more talking, faster living,, diet, indoor climate, etc.). This drops our co2 levels and our availability of oxygen at the cell level (due to the Bohr effect). This makes the immune system more alert and overreactive (pollen, allergens) and you get more of the allergens in your system by breathing more than you need. By learning to breathe through my nose 24/7, and slower, I completely got rid of hay fever and other allergies. Had it for 2 decades!! Many other health improvements as well. I know it sounds good good, but really... You're a science and data driven person.. invest a bit of investigative time into the Buteyko method for a possible huge improvement in health quality. Allergies can be a hell!
Online course, + how to disassemble and components function explaination, good not only for engineer but enthusiast mechanics as well, love your content
Great overview. Thanks very much
Love the idea on the Table, would also love to get some of those motors in a display case or something for mounting up in my shop. Lots of cool ideas!
So fascinating to see all the different approaches and how they're done.
I've been in this room quite a few times! Awesome place, every auto OEM uses these guys for benchmarking
Really enjoying your videos! Signed up for Patreon as well! Keep them coming.
Awesome, thanks so much for joining, Michael! Thank you for your support and looking forward to interacting on there!
Its great you show the motors, but if you could explain the pro's and cons either way it would help differentiate the different designs. There is a ton of info but no payoff in the end.
Not a bad idea with the tables Sandy. Amazing job as always.
Sandy, you’re the greatest!
The rotor of the e-tron is ludicrously old-school, technology-wise. Very much what you find in standard, industrial AC induction motors. Induction motors of the Model S used copper rotors instead of aluminium rotors, which is a lot more efficient because copper is a lot more conductive than aluminium. Man, i understand now why the e-tron is so inefficient... that's German engineering for you.
Actually aluminium is more conductive compared to it's weight (specific conductivity) compared to copper. And weight of the rotor is important because of inertia. So while copper helps with efficiency it's not always the best choice when it comes to performance. Also aluminium casting is really cheap compared to machined copper. It's always a trade off.
@@ytxstream Well, I don't think rotor inertia is a huge issue there, because it's negligeable vs. the inertia of the whole car you want to move.
So the important point here is the electrical resistance, and should be as low as possible for better efficiency (because the currents inducted in a rotor of an induction motor are quite large, hundreds of amps in that case). Imagine an induction motor as a transformer in short-circuit at its output, the primary being the stator, and the secondary the rotor.
But anyway, the e-tron efficiency is catastrophic, so for an EV, this kind of AC induction motor with aluminium rotor is a poor technical choice.
@@ytxstream Rotational inertia doesn't matter much for highway efficiency since the speed is steady.
@@ytxstream "Actually aluminium is more conductive compared to it's weight (specific conductivity) compared to copper" - Which is what matters most in cabling (when the goal is to keep mass down), but *not* in a motor, where flux *density* is the key. Increasing the volume lowers your flux density.
@@ytxstream I dont' think that machining copper is that expensive when looking at how important the efficiency is and how expensive those cars are. Also, I would assume that inertia is almost negligible in the automotive use case(the energy of spinning rotor vs the energy of whole car moving). Copper is also way denser making the whole rotor smaller so the radius can be smaller further reducing inertia if you want that. Tbh I don't think there are any real positives of aluminum other than a lower cost(which maybe makes sense in some cheap devices and not a car for 100k).
Amazing content, very very interesting!
My new favorite channel.
Everyone does their motors differently because everyone has gotten patents preventing each other from sharing designs.
Tesla allows others to use their patents for free in perpetuity
@@skaltura While technically true, it is not that simple. If you use Tesla patents, you also have to release your own patents that are associated with similar technology.
It is a bit like a GNU license but for patents. The automotive industry being conservative as hell, it is unlikely to happen.
It could with some newer and smaller startups. But if you go too far, Tesla will sue you, as hast happened with Xiaopeng Motors.
@@Findalfen wasn't tesla suing the employee for stealing autopilot secrets and not xpeng for using patents? those are two very different things
@@butterflysleg9649 Yeah, i think Tesla sued the employee because he uploaded autopilot source code to his cloud and that gave that to xpeng motors. Just search "xpeng motors stealing" and you should find plenty of articles going into detail of the story.
@@Findalfen Wasn't it more like if the patent user's mission is the same (like only doing evs, and competing against ICE production).. Not that you'd have to release your own inventions for free too..
Awesome work sir
Good compilation and comparative of motors.
A very interesting overview of Electric Motor design. Please keep the content coming. Take care.
Munroe keeping it real at the end - thank you sir
Great idea. I bet people would enjoy a master class from you. Also what about an educational series for kids and adults. Lots of grants etc for such projects. Love the work it must continue!
Great work!
Your videos are very informative I love the technical details thank you for sharing. I don't care for the parts or the auction. But I would love to see a model wire rim up close. They look beautiful.
Quickly became my favorite channel. “if anyone is interested” Yes, we’re all interested, in whatever you got
So cool, thanks sir Munro. This'll help me design an affordable but not a toy EV.
Great video!
I too have the same or a similar throat issue and need to clear my throat constantly. This is more of an issue when giving lectures or training sessions, i.e.: talking a lot. Keep going, love it all.
😳 wow. Big work!
The Tesla motor is outstanding! Mr. Munro, you seem like an great guy producing quality content and no bs. I look forward to the rest of your uploads. Great job!
thank you for this great video.
is this a trick question at 1:46 if we're interested in additional informations about it?
another excellent video, great to see comparison with different ev motors , and great that you guys are looking at ways to bring income in.
Thank you Sir, I like your Facom screw drivers too,
that was really informative thank you very much and I wish you a great day! Greetings from Germany
