I like this CEO. No fanfare. No PT Barnum style. Just the real deal. And his physics explanation are top notch
Incredible company with amazing future prospects!!
That is how a real engineer talks.
Much prefer him to Henrik Fisker Barnum
No PT Barnum system right 😉 how many cars did he say he will deliver in 2022 yet again then keeps cutting the n up numbers every quarters 😅.
@@rj8u how many cars did Fisker deliver? How many is fisker delivering in 2022- or 2023? Rawlinson and team made a sick product and Elon discrediting his abilities is sad juju
I never expected to see a REAL tech talk by a REAL CEO. With real physics and real math. Amazing! Keep going. After TECH TALK Ep.50, i will build a LUCID myself ahah.
Wow, If Peter had been my math teacher in High school, i could have become an engineer.
I might have gotten past Algebra.
@@mikekno6922 correction. Those who cannot do, teach.
You still can bud!
If Peter would have been your math teacher and not ceo, Lose-it might have had a chance and millions of dumb investors still have had their money... R.I.P.
It's a big treat watching an informative video that lasts more than 70 minutes. Thank you for showing us the innovations in technology, and explaining technical terms in understandable chunks.
The market seems hungry for EV engineering info. Just look at the traffic the Munro channel gets. Here we get the data dump straight from the engineers themselves, from physical principle, to design intent, to mechanical design, to manufacturing. This is phenomenal. *Nobody* does this, laying out the "secret sauce". Bravo Lucid!
Reprehensible to present this as an educational video (not a stock pump) while omitting to mention the most important engineering fact: Lucid is running its motor at DOUBLE the Voltage of the Tesla Plaid motor. No they didn’t miraculously double the power density with neat wires and magnet placement. Chances are if one applied 924V to the Plaid motor it would out-perform the admittedly nice-looking Lucid contraption. Plus the Tesla doesn’t need a rear differential at all. It has independent motors for torque vectoring.
@@juliancox3229 This video is part of a series. In the battery pack tech talk he goes into some depth talking about the advantages of Lucids 900v architecture.
If you would rather watch a stock pump video, there are numerous Hyperloop/Solar Shingle/Autonomy Day/Battery Day/Semi-Roadster-Cybertruck-Dancing Robot type videos on a different channel here on TH-cam.
@@Miata822 Not impressed. These doubled motor performance figures are a function of doubled voltage, see physics. if you honestly believe Rawlingson can out Elon Elon and break the laws of physics X 2 with nice prefab motor coils alone, then I guess from you at least he has earned his Swiss watch.
@@juliancox3229 electric motors don't work that way, or even close.
Maximum available voltage is only used to drive the motor at the highest end of the operating speed range, to overcome the back EMF which is proportional to speed and magnetic field strength, so having more voltage available would make no difference to the motor over most the speed range. At low speed power is limited by torque which is limited by the current and the magnetic field strength which the motor can withstand, as well as the current limit of the inverter. In the middle of the speed range the limitations are usually in the rest of the system, such as battery discharge rate and inverter power limits due to heat dissipation, but can also be limited by motor heat dissipation; this is the constant-power region explained in the video.
If you applied extra voltage to the Tesla motor you would just get excessive current that it can't handle.
Even a motor designed for higher voltage doesn't have much of an advantage: to use the twice the voltage it would have twice as many turns of wire with half of the wire cross-sectional size, carrying half the current... for the same magnetic field strength resulting in the same torque and power, and using the same electrical power. The upper speed limit doesn't change because with twice the number of winding turns it needs twice the voltage to reach the same speed against back EMF.
@36:07 No, the accelerator input does not control the motor drive frequency. The motor drive power is synchronized (that's why it's a "synchronous" motor) with the rotor position. The accelerator signal is used to determine motor current, which determines motor torque output, which causes the vehicle to accelerate, which is a change in motor speed, and the inverter follows that speed.
That sounds logical. Current trying to follow the frequency sounds backward.
Another amazing lecture on physics, magnetism, material science, production optimization, and much more, all condensed in a little more of a hour.
And the best part is, all of this come from the CEO and a VP of a company!
Thank you so much fo educating people at this level and good luck to Lucid!
Now that's what happens when incredible engineering and vision meet to make a groundbreaking product! 👏🏼
This is like the ride at the beginning of Jurassic Park. The CEO is letting his engineers teach him along with the audience even though he already knows (and probably contributed to) the system specs. This is such a great series. Thanks Peter and Lucid, please keep these wonderful vids coming!!
Amazing Job Lucid Team!!! We see love, passion, technology, science, competence, intelligence and many decades of experience creating the best possible car we humans could possibly conceive. Congratulations Lucid team
Lucid have a great future ahead of them. Demand for EVs is going through the roof. Best wishes from an investor in the UK. RIP the Queen. Looking forward to Lucid vehicles being sold in the UK. Lucid has great tech.
Sold in the UK? They haven't even started selling here in the US, so wait sitting down for these ones friend. Great innovative technology and good looking cars but aside from being a bit pricier than the other *cough* American company..... come on just freaking say the name..Tesla!; Lucid is having a hard time mass production, they will eventually get it though. They just didn't heed a smart quote that said "Making prototypes is easy. Mass production is hard!"
@Richard Portillo Why don't you let Martin speak for himself and go worry about your own personal issues. He can certainly look forward and may eventually happen. Good luck.
This motor is insane engineering. Its so awesome to watch the engineer CEO explain the amazing engineering of the product he sales.
This is the most I've ever been satisfied by any lecture in my life, Lucid definitely has a really promising future here
That was so fascinating. I'm no engineer but do think analytically. I'm very impressed with every little detail. I've met Peter many times in Tempe AZ and he treats ALL staff equally as kind and with respect as his engineer Emad. Much respect Peter.
My lovely impeccable tech talking about perfectly EV car in the world!!! Welcome to distribution and cooperation in LUCID STUDIO LVIV
I do hope that day is coming for you! Stay strong.
@@Miata822 Thanks a lot
As an EE and a big 'motor design' fan, I literally found myself applauding you guys for the engineering work, especially the heat removal method... but by then I had already gotten giddy about the stator windings! GEEKING OUT HERE!!! But for now - I have to get back to work... this was my lunch time treat (at least half of it... I'll geek out on the rest tonight at home!)
I wish Tesla would disclose a peak HP figure and I wish both Tesla and Lucid would disclose peak RPM. I suspect the Tesla motor is actually capable of more peak hp and peak RPM. Though overall the lucid motor is clearly better.
@@bob15479 Tesla with Peak RPM... maybe the carbon fiber wrapped one, but remember that the only reason they had to do that is because of the rotor laminate design, which has floating laminate sections above the magnet "V" - that are essentially non-supported - and would detach at high RPM.
Not so with the Lucid design.
@@beforebefore That´s not the only reason for the carbon wrap. Any rotor will expand at very high rpm. Meaning you actually need extra distance between the stator and the rotor with the traditional design. The Lucid laminate shape is what you´ll find in other rotors. Chevy Bolt laminate is almost the same. One thing I disliked about this video is that they make these things sound like Lucid is the first that realized where to put the magnets or cooling. Nope, everyone knows closer is better. There are always compromises that influence the final design.
@@michalfaraday8135 Tesla designed a rotor with basically a floating segment that sits between the magnet pairs... bad design choice. This required the carbon fiber wrap, which is far more "increased diameter" than just material expansion at the nominal 20k RPM... no steel alloy material would expand that much at that RPM and survive. This allows Lucid to run much tighter coupling between stator and rotor for much better efficiency and power.
@@beforebefore If that was really the case, why would they do that? If you look at Model Y, the main magnets have the same position as Lucid. Chevy Bolt is even closer and has almost the same design as Lucid for all magnets. There is nothing special about the Lucid laminate profile.
I love this tech talk. It's like the prefect lecture session I never had.
Please do more "Tech Talks" videos! I love them so much!
It's amazing how far we've come with BEVs, from EV1 to Lucid Air
Amazing engineering… Great minds at work! Peter Rawlinson and Emad Dlala definitely LOVE their jobs! Haha, they both want to talk at the same time! Thank you for all these tech talks. So informative and such detailed explanations.
Peter's voice is really enjoyable 🤝
These guys has so much fun!😂 They just bubble of happiness. Both just want to speak at the same time😂
Can't wait to see a single-motor 64kwh sedan! Super hyped for the affordability!
I am really glad to be part of this!! Love your cars
Tech talks like this remind me why I love this company and have an order.
Absolutely fascinating. I am not an engineer but I was glued to the video. Peter made it sound so simple, clear and, well, lucid(pun unintended) 🙂! Thank you Pete! All the best to you and your team. Hope to see your cars being sold in India one day in the not too distant future. There will be many takers for sure! Best....,
These videos are so well produced and explain complicated information in a relatively simple manner. Well done.
Outstanding expose Peter, Emad IMHO.
This brings tears to my eyes. Sending strength to Rawlinson and team.
The extra thought and drive for excellence in performance and efficiency comes at a price which I am more than happy to pay for. All of the tech talks have been interesting, but this one by far was the most interesting and informative, especially seeing the comparison to the competition.
Thank you very much for posting !!
Being a development engineer myself, I can really feel his passion when he explains this context. It's a pleasure.
I've been going through this vid a little at a time so I can (try) and comprehend some of the lessons. I'm about 45min in and now I really think you guys are showing off... Wow, I'm just blown away by the relentless approach towards efficiency and excellence in engineering. Bravo!!
Thank you! Huge respect to you and the entire team of Lucid Motors. Best wishes!
I’m absolutely loving these talks.
Great detail. Calm and interesting. Two obviously extremely talented and passionate individuals
I am fascinated how many internal intellectual property they disclosed to the public. The hairpin winding without brazing, genius. Differential inside shaft, whow. Rotor with that speed without carbon fibre bandage. Impressive. Encoder at rotor… so many details in one video, still flashed and digesting the content. I wish Lucid all the best. Brilliant motor at least. Hope they get ramping up production soon. Would like to drive such a car in order to compare to my Audi e-tron. Looking forward to new tech talks. Great to listen.
They Waited until they knew the OEMs who cared had already bought a lucid and torn it down.
Everything which is actually novel will be covered by patents, which are inherently (and very deliberately) public. And competitors and other interested parties buy and tear down everything available in production, so there are no secrets about physical designs.
Great video even for us math challenged. One of the things that got my attention early on with Lucid is how efficient they have packaged their motors, BMS and inverters. I think they have a great package for those last mile delivery vehicles. I'd love to see a Lucid powered 65-69 Corvair conversion just for fun.
wow, a single take. Blessed to watch his videos.!! You can feel the passion while explaining. Truly exceptional!!
Wow! This engineering is unreal. What great answers to the challenges of electric transportation.
Love watch these. My Lucid was damaged and I won’t get it back from repair for 3 months…I want to go drive it and appreciate all of this!
Thank you Mr. Rawlinson and your team!
i didn't even have enough patience to finish 45' lecture video when I was in uni. Yet here I watched through your 72' video tirelessly explaining physics and thermodynamic and motors with such enthusiasm. Thank you very much Peter.
You can just see their excitement and passion. They are people that love every minute of their job. I wish them the best, and hope they continue revolutionizing EV.
@@rami8896 These motors are so efficient, it has allowed Lucid to have the longest ranges that Tesla can never hope to beat. Now is time for Lucid to apply these advanced motors to build standard ranges and smaller cars that can be built much cheaper. Just imagine, 500 hp cars with 300 mile ranges. It will beat all the SUV EVs in price and performance.
Another wonderfully informative video from Lucid showcasing their engineering prowess. The fact that the personalities involved are bursting with enthusiasm only makes the video even more compelling to watch. Well done Peter and team. I can't wait to see these cars on UK roads.
Absolutely fascinating and a pleasure to watch. I wish I had people like this in university. Please keep up all the hard work to show what EV's are really capable of doing.
Great explanation. He would make a great mechanical engineering professor for sure!
thanks to this production and the carbon wrapped motor of the competitor! it appears to me that Lucid's motor is more expensive to make and they achieve higher HP/power by reducing the radius of the motor then compensate the loss of torque through gears. Competitor's motor appears a lot cheaper due to conventional design. The reason they are forced use carbon wrap is they have to reuse that existing conventional motor design, but since the rotor radius is slightly larger, the centrifugal forces are too much to reach higher RPMs/Power.
in short, electric motor design pretty much a compromise, no one is significantly better than the other!!😁
I listened to most of this while mowing my lawn. The 19hp Briggs & Stratton weighs 77lbs. 😂
Also finally found someone who legitimately needs to wear a Rolex milgauss.
This was excellent engineering shade, competition is fun to watch.
Now you can have a 500hp law mower! Reverse the blade and it will be a hovercraft.
Great thorough walkthrough of the power units and approach in design versus the newest technology from competitors in the segment. It was great listening to Emad and Peter showcase Lucid's industry-leading design approach.
Absolutely love their instructional and easy to understand explanations of their technology down at the deepest level and by the company CEO. It is something though that he is essentially more about teaching us all basic physics instead of actually the technology in the car. He would be a great university professor. I really hope Tesla motor engineers are seriously studying this video ;)
Awsome! Thank You! I've been waiting for this.
EDIT: WOW! This is definitely a "Watch it twice and take notes" video! Information dense. Love it.
I'm starting to realize why my Air GT is so brutally quick. Naturally I now want you to find a battery chemistry that will let me put more Amps to the motors for even more power (which I totally do Not need).
Thanks again!
I'm loving these videos. I can't wait to get my lucid pure, more range and so much cheaper than model s. Hopefully it comes soon
production begins next month for Pure and Touring :) WOOT WOOT. - Lucid employee
Even if Lucid never made cars, it could sell components and be a viable business.
I was thinking exact the same
Thank you for this impressive display of engineering. In my view, LUCID has a very bright future,
the first 20 minutes make such perfect sense when you simply use metric instead of moronic imperial lol
Totally loved it. My first comment ever on a video but it was so well explained. Really looking forward to more of these tech talks. I am heavily invested in Lucid and I believe it's a good one despite the current rate because of the technical prowess of the company.
I have done a ton of research and I'm now 'fairly' sure the premium German sports car is Porsche Taycan - and the America tri-motor car is Tesla - but don't quote me 🙂
They said it without saying it 😂😂
Another great video. Having an engineer and technical fan CEO, is a clear advantage for an automotive company.
That's what I call automotive engineering. Thank you so much for sharing all this.
Simply amazing, informative and entertaining. Thank you guys!
Another great tech talk and I am impressed. I’ve seen a few Lucid running around the Bay Area. Can’t wait to see more. Best of luck Peter. It’s nice, particularly these days to see a CEO that respects his team and customers.
Thank you so much for such a transparent and in depth breakdown! Grateful for the information that is being shared when most companies keep even the most trivial of improvements under bunkers.
I love these videos, more please... That differential engineering is a thing of beauty!
Loved his explanation, he can be a great teacher.
Thanks; really enjoy following along these videos ...!
Smiling all the way on this and only 25 minutes in. Lesson in presentation art!
The attention to detail is excellent. That work on the continuous wave winding with the stator is brilliant.
Underrated tech talk, so much information in a single hour.
Brilliant video production, writing, and delivery. Obviously Lucid is leading in efficiency. If they can become competitive with price, NVH, infotainment experience, and seated comfort, they will dominate. The drivetrain is top notch.
In these series, you make this brilliant tech almost open source. Mind blowing🤯
The 44 second TH-cam promo add for this video was outstanding.
I will be back later to get educated about the Lucid technical advances.
Good to see people proud of what they are building.
Sir you had missed something , you are using 900V system rather than traditional 300-400V system which already cuts down current to half and I²R losses to 1/4 , more than 75% reduction in heat losses.
After we see this great tech, passion & enthusiasm, we are confident about Lucid future.
we just waiting to increase the production, for our LCID status.
We are living in a fantastic tme ,an explosion of technology and engineering. Absolutely wonderful and informative Lucid videos the i learnd so mutch from.We need more videos like this too help remove the ignorance of what people think about electric powered vehicles ,imagine in just five years time from now .
Lucid: Mic drop. Absolutely fantastic! Reminds me of my grad school days in automotive engineering!
Im soooo glad I own so much LCID stock! Im just giddy with joy right now.
Another episode of lucid explanation of how so many basic/simple concepts/tools create so much bigger splash when applied by beautiful minds.
What a great, informed and clear description in all aspects presented
This man communicates so, so well- thank you
This is a brilliant explanation! What an amazing product! Well done lucid team
I’m so happy I have one reserved and will be very proud to drive this amazing machine.
Well done Emad and the team working with you to design a such technology
Amazing Video. I just wish other EV makers would consider doing something like this as well to share their passion and expertise.
Amazing design and technology, congratulations to the entire LUCID engineering team!
Absolutely - System Engineering wins the day!
Thank you gentlemen for this deep dive into the magic of efficiency!
두 엔지니어들의 열정적으로 설명하는 모습과 놀라운 모터 기술력에 루시드의 미래가 밝아 보입니다.
Stunning! WOW!
Wow. Lucid is definitely a tech company. Excellent presentation. I can’t wait for what other tech you going to come up with next.
I love watching engineers geek out on tech. Hope to see more videos like this! Can this motor breakthrough be applied for air conditioner compressor motors?
Surely can. Lucid optimise the design and dimensions for a luxury EV with ground breaking range and power. Lucid has achieved them, beating Tesla by a huge margin, but the luxury elements cost too much. By removing luxury, sticking to items that are easily mass produced, like these motors, there is no reason to doubt that Lucid can beat Tesla in price and performance. Elon has alienated the very best engineers on earth, sticking only on obedient and hard working engineers. This is the price of Tesla's egos.
Reading the comments here, you can see there is an actual audience for quality material like this. People are, rightfully, freaking out. Yes this is marketing to establish their brand as being high tech, credible and differentiated. And this is precisely how you do it!
Great physical lecture.
I already have one on order. This just makes me want it more lol
When's the tech talk about transmission coming? Also, a separate episode about suspension and control arms would be appreciated!
I love this Tech Talk format and it was great to show to my son who is considering starting engineering at Uni next year. That said, I am confused by the Peter's inference of achieveing 11% efficiency improvements over the competitors. When I look at the closest Tesla S model with 100kWh battery and the Air at 112kWh then the kWh/mile makes the Lucid just under 4% more efficient. I realize that isn't apples to apples, but the design improvements demonstrated are best proven through improvements in efficiency, lower costs and/or improved reliability.
Peter's tech talks are awesome.
This drive unit, the plaid c.f. wrapped motors and the koenesigg quark setup are simply amazing engineering marvels imo. 😎
Makes me excited for the future of evs and especially high performance evs. Well done team lucid I say! 👍🏻
Im becoming a lucid customer before I lost both rear drive units in my plaid within 6 weeks of one another and tesla could seemingly care less about me making 2 $1500 car payments for a brick
The CF wrap looks like a Band-Aid solution. The internal differential and dual transmission solution is really amazing.
@@pasad335 a band aid solution? 😂 the fastest accelerating production sedan in the world uses 3 of those band aids. And recently went 217mph unlocked. A car you can buy TODAY with even LESS hp and tq than the lucid air dream perf it stomps all over btw. 👍🏻😎
@@4literv6 We took delivery last August of a Model S Plaid to replace our 2015 P90D, and we took delivery at the end of December of our Lucid Air Dream Performance. The Plaid is marginally quicker than the Lucid, but the Lucid handles better (especially under hard acceleration in which the Plaid front end goes light) with a more compliant suspension, has considerably more interior room and luxury, and -- unlike the Plaid which started developing creaks and groans around 8.000 miles -- is solid as a rock at 10,500 miles. If that's your definition of stomping the Air, then yeah . . . the Plaid stomps the Air.
@@4literv6 i guess we will see once Lucid’s tri motor variant, Sapphire, comes to market with its significantly better performance figures.
This drive unit should be sold for every conversions,game changer
Fantastic, another level of effective comunication here.
This is what I call HEALTHY COMPETITION for the Consumers benefit in the years to come!!! Thankyou for sharing. I am excited when the prices are more affordable for the working class. Working class spend more in Volumes then the smaller number of Wealthy that can afford these now.
This is fantastic work guys! I wish you the best of luck on succeeding on mass production!
Great video. I love lucid. It’s just confusing that the Tesla plaid Carbon sleeved motor is only capable of a output of 250 kW when a seven year old model s rear drive unit can output 440 kW? Even the small front motor can output 297 kW..
They are using the quoted plaid S figure and dividing by 3. It can output more than that. It’s one of a few sleights of hand in this video .
The series of motors which started with the Model 3 are smaller than the old Large Drive Unit motor - so much smaller that two of them fit in the Plaid's rear drive unit. You can't reasonably compare the output of motors of different physical sizes.
Also, the old induction motors overheated almost instantly when used at the those high power levels that Tesla advertised to look good; the current permanent magnet motors (including the variant in the Plaid) produce less heat in the rotor (because they are PM instead of induction), and all of the current Tesla motors are better cooled than their old motors.
The continuous wave bar winding and the cooling "microchannels" are the impressive features of this motor, and both are illustrated well.
Some great stuff!
Wonderful firehouse of great info. Completely reshuffled my thinking about Lucid v Tesla v all other EVs. Thank you !!😊
Peter !!!!! We are all cheering for you !!!! 💝
Awesome video, love the comparisons to the obvious competitors! Makes me proud to be an Imperial College alum :) I love my Tesla but would love a Lucid and wish them the best, clearly they are making some fantastic advances!
