As Tesla moves from scrappy startup to established carmaker, they're looking to streamline and optimize every part of their supply chain. And while a lot of attention is given to battery materials and supply chains, Tesla has been working on a next generation electric motor that elimiates rare earth metals, that are expensive and in short supply. They believe these new motors will be much cheaper to make, more powerful and more efficienct. So how are will they do this? let's find out! The GENIUS Of Tesla's Next GEN Motors!

You should give a call to Robert Murray Smith of the Thinking and Thinkering channel! He is a nice guy and I think will be happy to do a collaboration with you!
As exciting as these improvements in magnets are for the e-car industry, there are other industries that could benefit greatly as well, from medicine (think MRI for instance) to aerospace and many others. Anything that cuts down on the cost and especially the weight is very valuable in the aerospace industry.
Good video presentation!
Even your sponsor segment was interesting. that @EcoVacs is interesting tech. Maybe a full episode?
Sell teeshirts the age of super mediocrity

I am going to get one.
Then maybe get a pet.
This is such a breakthrough. People aren't talking about this nearly enough. The implications beyond electric motors and EVs are massive, and all of it at a 50% lower cost? Think smaller, cheaper MRI scanners, more efficient electric generators, permanent magnet maglev trains, you name it. And, let's not forget, even more awesome UA-cam videos of people playing with magnets
Planes, trains etc. Once we have a way to mass produce it everyone will want it
To take full advantage of this they probably need to license the tech to others rather than being the sole producer. In some ways it’s a shame they’ve started to build fabrication unless it’s to be used as a demonstration to get licensees
One of the reasons is the so-called tech media is Pro GM and Ford, despite them being obvious laggards.
Can't wait for these to show up for RC cars.
What is stopping this from replacing in-home electrical panels or large substations? Energy free from blackouts is true independence......so clearly, governments are the biggest obstacle to widespread adoption.
Wow, material advances like that are very important. Hope these magnets can be large scale produced for a good price soon!
Yeah soon
Listening to an engineer SO MUCH BETTER than listening to a "journalist" who knows nothing. Thank you for great content without wasting my time!
AC induction motors have an issue at high RPMs - they have cogging; which is brief moments when the magnetic fields are pulling the wrong direction. I.E. they are having to "fight" to keep the motor spinning in the right direction.
The Model 3 motor has (at least) 2 important innovations:
The magnets are made up of a series of 4 sections that have the north/south orientation in different directions - called a HALBACH ARRAY. This "focuses" the majority of the magnetic field in ONE DIRECTION. Which vastly improves the usable strength of the magnets.
The flat magnet bars (of the Halbach arrays) are angled in shallow Vs so they "conduct" the magnetic fields to almost eliminate the cogging.
Unfortunately, Munroe was wrong - the Tesla magnets were not arranged in a Halbach array. The magnets were laminated to reduce eddy current losses. Tesla no longer laminates the magnets in their newer motors.
@@kn944 I wasn't referring to Sandy Munro on this. But you may be right, as I only was mentioning what I had heard from another source.
A Halbach array may or may not have a benefit, but if it was a help to make motors even more efficient/cost less, then it is possible.
Incredible research on the subject Ricky. Thanks for making a video on it. I hope this magnet tech really makes its way down the chain quickly as it could really help industrial applications have better performance and save power. I know id love to get my hands on them.
Me Two
It’s Rare to hear such good scientific news for the Earth.
indeed it is...and hopefully we see them really soon
Nanotechnology was such a rage in the early 2000s and now it's so common that most people don't realize how important it is. This entire breakthrough is only possible thanks to the tools developed through nanotech. Iron nitride's awesome magnetic properties have been known for almost a century, yet the only reason no one was able to put it to market was that it was too hard to reproduce at scale. But not anymore!!
Absolutely it really is the fundamental innovation making many old ideas now possible..... That really deserves a video of its own.
Nanotechnology has been around since the 1950s when integrated circuits started to be developed.
May the Force be affordable so we may all prosper.
Amazing! I think you’re on to something here. Would be so great to move beyond rare earth magnets.
Great video Ricky! I came here from Dillon's Electrified channel. I didn't realise you had your own channel - I've only seen the excellent EV reviews you do for the Fully Charged Show
Very cool exciting to see these technological breakthroughs happening which will greatly accelerate our transition to electric vehicles
Note: Great VIdeo. The Temp tolerance for the magnet infographics were missing text in the lower porting of the infographics
Awesome video Ricky. Really interesting, I had no idea about iron-nitrate magnets. Very cool.
Iron-nitride - Fe16N2 - no oxygen involved ;^)
We finally have the final component to make the Flux Capacitor, Go Doctor Brown!
Thanks for answering a question that has bother me for the last two weeks. An induction motor will still coast better. Good job Ricky!
you make really high-quality content here... every video is like a well-organized feast... the effort you put into your content is truly amazing...keep it up...expecting more of these videos
wow thanks for the complement, we do work very hard to make our content the best we can....we still get things wrong and make mistakes but we aim to be less wrong.
This is a great video. Thank you. It would be great to see the process that shows how these magnets are made.
Hey Hugo. Niron is keeping shut about it, at least in terms of mass production (I would be too, for sure), but there are several research papers about iron nitride synthesis in the lab.
If Tesla is smart then keep it under wraps for a long time.
Thatsa secret
13:20 hits that heartbreaking note. Promising technology that’s not that simple. Let’s hope Tesla and U of Minnesota can deliver!
@1:10 Just to add some data points to the chart, Tesla/Panasonic 2170 cells in 2018 were at around 730 Wh/L and later ~750 Wh/L.
If cheap iron nitrite permanent magnet motors are able to perform as described here and they are already close to production, then Giga Mexico is something very exciting to look forward to!
Hairpin motors in Mexico or no
A kid named Robert Sansone (17) won a science fair last year over his new design for a electric motor without rare earth metals, and I am wondering if he sold them this design or idea.
This is a different technology, permanent magnet but without rare earth, not induction. I talked to Robert Sansone at ISEF in Atlanta, where he presented his innovation: an induction motor with the performance of permanent magnet motors. He had a good explanation for why these went undeveloped for a century: they’re unstable without high-speed computer controllers.
It’s an echo of the unstable flying wing aircraft that failed just after WWII (even top test pilots couldn’t control them) but resuscitated with stealth aircraft that could carry those high-speed computers to make them stable.
I, too, am curious if Tesla is working with Sansone.
Thank you for the great update! Would this be even better if combined with Exro Technologies coil driver to even improve both performance and battery efficiency? I would love your take on Exro as they say they work with all motors? Thank you and have a great day!
I'm interested in that induction motor design Robert Sansone came up with and whether that will be commercially viable soon.
This is getting me excited. This is going change so much, like potentially the way we do EVERYTHING
This could change alot of devices that use magnets... What do you think it will change the most?
One of the best information packed new technology videos I've ever seen.
Thanks Gunther, We try to provide as much raw value as we can.
THANKS RICKI , FOR ATTRACTING ATTENTION TO THE FUTURE…WE HAVE BEEN LOOKING 👀 FOR 🤗👍💚💚💚
This is really fascinating. Years ago I researched building low cost bicycle motors using synchronous reluctance controllers to avoid using high cost neodymium magnets, which would have cost way too much for the application. Amazing to see that industry is working to figure out ways to make us less dependent on rare earth elements from China!
America has large deposits of rare earth elements, they even used to mine it. However mining rare earth elements is a messy business, and with EPA regulations etc. it was just WAY more cheaper to buy it from China. So what America is dependent on is not rare earth elements, it's CHEAP rare earth elements mined far away where the pollution created to mine it cheaply is someone else's problem. America didn't just offshore for cheap labour, they offshored polluting as well.
The founder of Niron Magnetrics is ANOTHER Chinese genius... as USA wages aggressive war on China he may join the 30,000 PhDs that have already left USA...
good luck ro Niron Magnetics. If they can produce at scale and incrementally improve the process, it will affects all sorts of tech. Miniature robotics could definitely get a boost. Drones would definitely benefit and improve flight time for the same battery.
The Graph at 13:50 is Pretty 😎 👍
(Very thankful to be able to pause) 😊
Thanks we aim to please.
Great video. Nicely done, thanks
Robert Murray Smith from the Thinking and Thinkering channel did an overview of this months ago! Quite a nice chap, got to recommend him!
I love TnT. Robert's awesome and he's probably the image I have of myself when I get older.
He does have a tendency to downplay anything he can't build to work himself, though. I noticed that about the 3D-printed toroidal propellers he tried a couple of times. As if it was a simple matter of making a 5-minute CAD drawing and sending it to the 3D printer like most DIYers on YT seem to think (not Robert's case, though. He was just using propellers someone else provided).
First time viewer of this channel, and I have to say, this was an excellent, informative presentation. Clear, concise, no over the top BS. Excellent information! Thank you. I'm subbing.
Welcome aboard!
Nice work. Appreciate you, respect.
I assume it could also be used in wind turbines and revolutionise that renewable technology too.
I've been wondering about repowering and upfitting old hydro project turbines with modern more efficient easier to control through software motors&turbines? Ad grid scale batteries and floating solar to the reservoirs and it could drastically extend the usefull lifespan&output. 🤔
@@4literv6 That's a great idea. I wonder if it would make sense economically for companies to design and build new swap-on replacements for older turbines. I mean, dams are so expensive to build and they make such an environmental mess by flooding so much land once built that it would be a shame not to use them to their full potential, right?
@@Israel_Two_Bit exactly some dams have operated succesfully for over a century now. And the average one in use is over 5 decades old.
Not to mention in the U.S. many reservoirs are located on federal land so adding additonal upgrades wouldn't be the horror trying to get a new project approved is. To much nimbyism imo.
Another thing they could possibly do easily is ad large wind turbines around or near the upper reservoirs. As dams use hvdc links perfect for adding batteries solar and wind turbine capacity onto. Without paying large upgrade costs as a lot of them operate well under 50% of the rated or nameplate capacity. At least from the research I've done. Probably could earn a lot of $ for the upgrades to under the ira. 🤔
@@4literv6 You said it! Ricky made a video abut Aeromine wind turbines which work really great when they line flat vertical surfaces like the walls of a dam. That would be pretty cool to see, hehe
Nice shots of Bondi with the roadster
I didn't hear about this anywhere else. This is really good info!
I'm excited for when this tech reaches commercial scale
What about Windturbines? Any chance these magnets could be used for that? It would totally solve our China dependency problem too. This could be the game changer we've been waiting for to give the energy revolution a huge boost.
Good point. They're reverse motors after all
Wind turbines can be theorhetically increased in total efficiency by 38% using counter rotating rotors in a counter rotating blades wind tower design. Mechanical losses are the limiting factor.
The Sansone motor has a denser torque flux as the flux lines are fed at two 90 degree orientations to each other whicj can combine the benefits of both axial and radial flux and thus increase the saliency ratio..... (Weight to power ratio and torque density to Power phase frequency) this means as a generator it would be more efficient than the current max of 70%>>>> this means smaller generators, lighter and more powerful with current phase transfer ranger that is more efficient at recovering eneegy with a dmaller current management demand.... (Smaller.lighter inverters)
It means that Wind Turbines can double in energy output per unit.
@@jeanpaulchristian3282 Hahaha, Jean Paul, you must be an engineer. Couldn't follow all you said but what I understand is that the short answer is: YES!
@@jeanpaulchristian3282 it must be the desire to know more... I appreciated your detailed feedback.
@@jeanpaulchristian3282 Counter/contra rotating turbines are already on the horizon with an insane max output target goal of 40 MW per turbine by 2029 for the company World Wide Wind.
I already know how ridiculously strong Neo magnet are (those that i take out of broken HDD) So if you tell me in the coming years we'll get something even strong then wow. I wonder how rust-resistant they will be. I guess they will just nickel-plate those magnet like Neos are.
How long does it take to charge ? What special equipment is needed to charge ?
Fabulous vacuum cleaner-pet follower, the iron-nitride magnate availability is a great news for all of us who are saving to buy a Tesla as soon as posible.🎉
It really is!
I have been bothered by the claims of induction motors having higher torque at low speeds. What we were taught as part of our curriculum was that the squirrel gage motors had a miserable torque at the low speed, despite of pulling huge amount of current at the start. Their maximum torque was obtained at something like 85 to 90% of full speed. Actually, we verified the torque curve in lab exercises. Now, what I suspect is that the talk about better low speed torque relates to variable frequency driven motors. Such motors are not traditional squirrel gage induction motors, but closer to either synchronous motors or externally commutated DC motors. Has some standards body established new naming practices?
squirrel cage, not gage, which would also be spelled guage...
Aside from the design of the rotating flux motors as described in this video, pancake axial flux motors have better low speed torque characteristics but given their design, pancake motors don't have the same high speed (>20,000 rpm) capability.
Perhaps a two motor solution is still the way to go where needed.
I am impressed not only by new magnets but presentation. Tvank you
Ricky, you and your team are awesome for bringing videos like this! Like you surmised, the technology has always been there, it just takes a genius company like Tesla to use their bright minds to find the missing pieces! In the 1950's the ingenuity wasn't there yet...
I think it's Niron Magnetics who seems to have developed the core clean magnet technology, not Tesla, but perhaps Tesla also cracked it independently and hasn't said anything? Hard to tell at the moment. We'll have to wait and see. But either way, it's awesome for sure!! Love this!
@@Israel_Two_Bit ...yeah, why would they only sell to Tesla? Kind of like Tesla fan club touting 4680 batteries which Panasonic are also making for Tesla. Once the expertise is shared, Tesla has no clear advantage over other competitors.
@@AudiTTQuattro2003
Why do you think Panasonic (and LG AND Samsung..... and possibly CATL?) announced 4680 cells *after* Tesla?
After all there was plenty of opportunity before, wasn't there?
It's because they hadn't cracked the cooling limitation of the form factor.
.
The tabless system came at that from a different angle, instead *preventing* resistive heating, removing the *need* for cooling.
.
Do you know "Panasonic are also making them for Tesla"?
.
If they are, do you know if they're doing so independently, or under the "play nice" open patent agreement? (That would seem likely)
We DO know the Panasonic version is using "wet process" Cathode and Anode (They have stated as much)
.
Same with LG.
.
It's going to be interesting when the TESLA 4680 section opens at the (Tesla!) Giga Nevada producing 4680 Semi cells.
.
I wonder if TESLA will then expand the 4680 production into the 2170 sections?
Will Panasonic remain involved?
Will cross fertilization produce an even better cell?
Will Panasonic, LG and Samsung produce full dry electrode cells FOR Tesla (and others?.... GM?😂) under licence? ..... That *would* be ironic.
.
I wonder what's going to be produced at the new CATL factory almost opposite Tesla Shanghai? 🤔
I wonder who's going to be using those cells?
@@AudiTTQuattro2003
Tesla is already in the lead. It will be almost impossible for anyone to catch up now. Period.
Tesla started the race ^long after^ after GM crushed their compliance EV1. Nobody else even bothered to show up, thinking "this quirky tesla company is just another vaporware with a single hotrod to charm people with". Then came production hell (the M3 at around 2017)...
STILL, no competition (even though bears always aggressively stated "the competition is coming strong". They'd say things like VW will overtake Tesla by 2022 (what a joke).
Meanwhile, Tesla has developed a better battery form factor for the WORLD, they've bought out whatever companies needed to assist in the R&D needed to do all these things, too. Hell, just ^Maxwell's^ dry electrode tech will reduce the space ^and the energy^ needed to make better batteries!
This is very important because "the competition" (roll eyes, LOL) can only source from a large communist country.
Tesla is everywhere (including making sure that a large communist country knows what it will take to compete).
Now, they are ^expanding all^ factories, building a new (and even larger) one in Mexico, and will continue their ~50% year over year expansion.
Haven't you noticed, They sell many more EVs than the year before?
It's really a "like duh" thing 😜
@@rogerstarkey5390 Wonderful Comment 👍
I love your video's this like so much of what you've had on the channel looks promising, problem is if this has been known about for 75 years and no one's done anything about it there's a reason. The actual raw materials might be inexpensive (relatively speaking) and abundant, but if the process to make them into useable "super" magnets is complex and difficult they may cost just as much or more to make than rare earth magnets. Raw material costs are only part of the equation, actual manufacturing costs are the other.
Hairpin windings are also a big deal. Stronger field for equal copper.
Thanks for the great info re iron nitride.
agreed Hairpin is a major improvement on its own.
To the TBdV team: new to the channel and my first vid. Great work! Script, presentation, data, research, analysis and on and on…full marks all around. I’m hoping TBdV can keep an ear to the ground about possible contract talks between them and Tesla. The Terran Space Academy recently reported on progress with room temp superconductors; wouldn’t that be a great paring!
Welcome , grab some popcorn Mr Ricky and his team are super great
How does this compare to the lucid motor which is apparently amazing in terms of power to weight output?
This sounds cool. Lets hope we see some
This is some of the most exciting new in motor technology along with the latest new on batteries. 🇬🇧 hopefully in the very near future BEVs will become the no brainer purchase as prices plummet.
It really is the big deal that not many people are talking about. I hope we see these new motors soon.
Wow, such interesting topics! Keep it up.
Glad your enjoying it. Any requests ?
Excellent development!! Nitron motors + Amprius batteries = Electric Flying Vehicles!!
indeed the two together could make Electric flight a reality.
Not just that either. Nitron motors + Amprius batteries + Toroidal propellers = electric container shipping vessels. A solution to, by FAR, the biggest polluter in the international shipping network. And given fuel is over half the operating costs of naval shipping, being able to dramatically cut those operating costs per cycle will give them a very attractive RoI on the initial investment costs of upgrading their propulsion system.
outstanding journalism!
The great thing about Pascals, (in thr minds of advertisers) is that you get THOUSANDS of them!
Personally I'd prefer a unit of measure that's more readily, 'visualised'. Pounds per square inch for instance, but then you only get 0.72 of those!
Interesting and informative information on Iron Nitride Magnets, thanks.
Just to be clear, a Pascal is a metric unit of pressure, similar to pounds per square inch. If you look on many pressure gauges, they are also calibrated in Pascals as well as PSI (or whatever)
So just as an inch is an English unit of measuring distance, a Pascal is a metric unit of measuring pressure.
@@SeattlePioneer Yes, the units are indeed inter-operable and convertible and advertisers like the exchange rate!
Yes, I inflate my car's tires to 206,820 pascals - that seems best.
Fortunately all manufacturers are working on a wide range of new solutions. They all are seeking a competitive advantage whether this or other areas of the vehicle.
Few seem to achieve the consistent across the board (and rapid) updates..
Wow, that's really fascinating! As is so often the case- what's old is new.
What's new is the method
@@rogerstarkey5390 Method is everything.
So with an improved magnet efficiency, does that mean less power draw from the same battery pack, thus increased EV range from the same battery?
No. Current motors already have efficiencies of above 90%. Any gains would be marginal.
Brilliant information, love your work 👏 👍
Thank you. It’s awesome to see this advances in magnets. ❤
Got your link from Dillon Loomis’ UA-cam from yesterday. Well done!❤❤❤
Awesome thanks for letting me know. Glad you came. Hope you will check out a few of our other videos.
Finally, a video about something that doesn't have some sort of gotcha at the end!
In addition to the magnets (which I think Monroe mentions) Monroe also talks about hairpin motor design (instead of coil) increasing efficiency by 20-30%. Maybe it's a combination of different magnets and hairpin design that gets the 30% increase? Do you have an opinion on that?
...and again, the hairpin technology is not exclusive to Tesla, Only maybe some of the processes and manufacturing of Tesla specific motors are. Where is the competitive advantage? Elon is a master of creating "technology hype" through UA-cam fanboy channels without having to undergo any scrutiny on what real advantage any of these technologies have for Tesla vs competitors.
@Brian Johnson
Hairpin wound motors have a better "fill rate" (less air between the windings) compared to "conventional motors.
This can give a more powerful magnetic field, so more efficient use of energy for a given input.
@@AudiTTQuattro2003
You seem particularly "salty' today?
Please provide the timestamp where someone said "Tesla invented the Hairpin winding"?
(Nobody did).
.
Tesla (not "Elon") is masterful at combining and refining on a continuous basis technologies which *may* have been invented by others, but have yet to be combined *efficiently* .
(You know the long list)
.
It's only "hype" if the end result is either nonexistent or disappointing.....
I'm trying to think of an example where the Tesla *team* has not achieved remarkable results....
.
If you're able to "provide scrutiny" *with evidence* ....
Go for it!
Do your worst!
@@AudiTTQuattro2003 Tesla is not about inventing, but about applying. While the rest of the world is saying "let's see what will happen". Tesla is moving forward. Obviously you have a problem with that.
@@AudiTTQuattro2003 You don't like Elon and Tesla, I think we all get it. But this isn't a Tesla Fanboy video. It's about the promise of new better magnets. I'm so sorry for you if it turns out to be Tesla (again) who beats the competition by applying this technology before everyone else.
But please do us the favor to use arguments that have something to do with this particular video. Yes, OTHER PEOPLE in OTHER CHANNELS have made statements about the "hairpin breakthrough" but that's not the case with this video. This entire video focuses on the real breakthrough represented by the existence of powerful magnets that could challenge neodymium as the industry standard.
First, Tesla didn't invent (and don't claim to have invented, as far as I know) the hairpin stator winding design or the no rare earth metal magnet. Second, hairpins aren't what's new to the new drivetrain, because they're already using hairpins for the previous generation motors (and this video is about the future designs), only the use of the new magnets is a real breakthrough, and that's what most people are missing.

Thank you for coming
Imagine the benefits to be gained if this new material is combined with axial flux design motors, and the latest battery tech?
At the height of global tensions with foreign adversaries who hold us hostage with fossil fuels and rare earth elements , this news is absolutely amazing.
Ricky continually leaves me impressed.
Ricky Roy for president!
(Well, no, because we'd lose these videos)
BTW, tried to check out the vacuum cleaner he speaks of but the website is nearly unusable on iOS.
That's just stupid on their behalf. They should fire their web development team.
Very exciting news, thank you!
I had never heard of this compound called iron nitride before. ...
come on back we will try to keep new info coming your way
Love how that robot vacuum jus shoved the dirt under the couch... 🤣
Wow and I'm blown away that's incredible if true ...just wow
It really seems like it is true, when we will see these motors and or magnets in products is the big unknown but it seems like maybe soon.
Neodymium is very brittle. is Fe nitride any more rugged?
How about the hair pin winding?
COOL info Ricky!!!
Glad you liked it.... hope to see these mags in electric motors soon.... the hairpin motors have already been seen installed in new teslas
*Series wound motors have only copper wire and use the same amount of electricity to make the same amount of horse power. As long as the motor is spinning it can also perform regenerative braking. Permanent magnets are a myth as far as a "MUST HAVE" item. Two electro-magnets can make a massive amount of HP! Cheap and simple*
Very nice. I want one or 10 of them to play with. What is the results of the power draw on a battery between all the motor types?
think of the low power, high strength of hand magnets for attaching to surfaces!
I imagine it's more a question of efficiency than (extra??) power draw.
If you combine a more efficient hairpin winding (fewer air gaps, more uniform induced field?) with a lighter, stronger magnet, you get more "bang for buck" in terms of force, compared to the old methods?
@@rogerstarkey5390 I think so as well, but would like a table/graph of results for the same Newton-meter/sec power output.
9:47
There’s another possibility: Tesla changed the directional axis of the weaker, old-magnet technology.
Axial Flux motors are synchronous motors which shrink the distance between the rotor and stator magnets - increasing the magnetic coupling between the rotor and the stator, for the same strength magnet.
This arrangement is scalable by adding additional rotor and stator layers, with very little additional complexity or weight. It’s like adding additional motors inside the same case. The only “limit” for torque, is how many layers you want to add.
You can use rare-earth magnetics in an Axial Flux motor, but you don’t have to.
How to buy shares in Niron Magnetics?
I don't think it's public. Is it?
Not listed (yet)
Iron Nitride permanent magnets engines. Got it!
Thats the guess
yup, this was the stuff I was wanting to know.
Shouldn't this type of magnets also increase the performance of things like windfarms and water powerplants?
indeed it could.
I had heard about this battery breakthrough just a while ago. All I gotta say is yay.👍🤓
This video is about motors?
@@rogerstarkey5390 oh my God, a critic. By the way, it was also about battery Although it was not about battery chemistries or manufacturability, etc. God bless you.😂✌️
Awesome video, job well done
Wow
Great video. Deserves a follow
The magnets in permanent magnet motor lose their magnetic charge over time. This was not mentioned in the vid.
Just one mistake in the comparison between Permag motors and induction motors. Induction motors are "sluggish" at low RPM, because you can't get the airgap voltage necessary to induce high current in the conductors of induction rotors. The maximum voltage that can be applied to a stator is directly proportionate to the frequency of the AC. As the frequency increases, the voltage can also increase, which makes it easier to induce current in the rotor. The induced current is proportionate to the torque of the motor, while frequency,(hand in hand with voltage) is proportionate to RPM.
With a Permanent Magnet motor, the torque is limited by the field strength of the magnets, regardless of speed. Like the induction motor, the voltage and speed are proportionate. A permanent magnet motor can produce its maximum torque from 0 to redline RPM.
What about axial flux motors though? (As opposed to radial flux.)
Places are charging 20 to 40 to charge batteries now. So when you travel or have to charge while out, cost savings is gone.
wow that's cool... Really cool. Almost superconductor-cool.
very very almost superconductor cool indeed
Thank you!
come again.
This is great. They need to solve the zero emissions during production problems and disposal/re-use/recycle problem.
