Fully Charged is an online show hosted by Robert Llewellyn (Red Dwarf, Scrapheap Challenge, Carpool), which looks at why we need to change how we think about energy consumption now. From looking behind the myths of renewable energy, to seeking the truth about electric cars, Robert Llewellyn demonstrates what the future could have in store for us all.
Those motors looks like they could be "stackable" so if you needed more power you could put 2 or 3 of them in a vehicle.
Yes, they wrote it on their website, looks odd but really cool modularity! Cheers
Yeah they're axial field motors. They're the future!!! And btw, I watch your videos they're so good.
OMG! This comment is 10yo this is way more precious than Ether.😂
@@learningcomponents5809 They are the future and always will be.

YASA Flux motors came up on my feed and my RUclips search brought up this video - fully charged was there at the beginning :) Good to see this is being used in production.
Brilliant as usual. The balance between sort of knowing what you're talking about, enough to ask the right questions and not knowing is what makes these little programmes so good. And also your clearly genuine enthusiasm for the subject.
Can we get an update on how things are going with YASA and their motors. Maybe a more technical aspect on how they work too?
Its in Koenigsegg Regera :)
HeathenGeek I'm on placement there at the moment, all I am going to say is you will start to see their motors appear in many more applications and consumer products, they are getting lighter, smaller and more efficient. Now just waiting for the battery tech to catch up!
hi. I want to apply for the yasa motors placement for 2017. I would like to know ur experience working with them if its not too much trouble
ikechukwu collins Tim Woolmer is still there, and he is the man who inspired me to join them. You will learn a lot and they are a great team of people!

@LosDTenaces Um, couple of things. DON'T SHOUT! It's rude. I admit it wasn't explained clearly enough in this episode, but truly, they don't need gears. Each motor drives one wheel, the motors are fitted side by side in the central part of the chassis, they do need universal joints but it is an absolute direct drive from the motor to the wheel just as we said. There are NO GEARS on the Delta E4 Coupe, the car briefly featured. It has two of the YASA motors, each one driving one rear wheel.
I only recently discovered your channel, and I find it one of the most inspiring and positive things on the Internet. More please!
Most motors have a rotating armature and a stationary field. The stationary field can be copper windings with field current flowing through it to create a magnetic field. This magnetic field pulls on the magnetic field of the armature creating torque. In this case they use rare-earth magnets as the stationary part to produce the field . The magnets then are the field windings. This type of motor is simpler and the magnetic field from the magnets is fixed. In other motors (especially larger DC motors) the field voltage and current can vary. Also the maximum efficiency (or Carnot efficiency) of a petrol engine is about 40%. That is only a theoretical efficiency and impossible to achieve. So the maximum real-world efficiency of petrol engines is high in the 20's or 30's. These YASA motors have real world efficiency's in the 90's. No comparison.
More compact motor = more space in the car itself.
Great technology !
200 year old technology in fact! The first axial motor was invented by Faraday
Let's hope that when full production takes place (and it will!) it is done in UK for a change.
First time i've watched this show and I'm a fan already. Going to pass it on to friends... Love it..
+Anthony Mann , Yes, they're all good.
I didn't know Fully Charged was around for that long! Wow, way to go :-)
At 6:25 I started to wonder how long it would be before he hurt himself when one of the magnets was turned around. The answer was at 7:17 so... not long at all. :D
This video is five years old . Has their products found themselves in affordable cars unlike that 2m $ Regera ??
I watched this 12 years ago, but even then I missed the part where they drive it on full power and only need the losses in the system to power it. What a cool rig.
I would love to see an update of where they're at 5 years later.
Yes. . . me too. Also some proper technical stuff about how it works.
Probably not a revolution technically. Just using really good modern batteries and really good modern solid state switches to tweak existing designs.
nowhere, because their ratings are bullshit
they are developing full electric flight with R-R. They just signed the deal with automotive OEM too. It is not too bad for once PhD student making millions out of his studies.
Keep up the good work! Nice to see the Brits are pushing the envelope of electric motor technology.
Most production electric vehicles are direct drive to the wheel and don't need a differential. The computer in the motor controller takes care adjusting it to give maximum traction and adjust rotational speed as it goes around corners. Makes it much simpler when you scale it to 4 wheel drive or 8 wheel drive (KAZ electric limo)
My Nissan Leaf's on order and can't wait to test 0-60 too
Shame you are located on the other side of the pond. I would just love to see this company and the products. Thanks for showing us all on RUclips. Peace vf
I am watching this ten years later!! and this is the year (2021) when Rolls Royce made its "Fastest Electric plane" with Axial Motor.
Would love to see one of these motors as a hub motor in the rear wheel of an electric bike..
so where is it now?
How many poles does the motor have? And is the number of permanent magnets the same as the number of poles? (I think for smoothness, the numbers should be relative primes).
LOL at 7:17! I spent a summer working at a magnet factory - awesome stuff. They were just rolling out rare earth assemblies and people were breaking fingers they were so strong.
I wanted to use a pair of these in my Flux Capacitor EV drag car. Perhaps YASA want to play with my next project?
The Formula Student team at my university acquired this motor for their electric car.. not sure how far they got with building the car.. google NMMU racing for more info.. i got to inspect the motor close up as i was briefly a member of the team.
Maybe Emrax motor is cheaper solution!
I had my first play in a Nissan leaf today at the Melbourne international motor show, they had it displayed on the dyno and I was amazed at how quickly I reached 140 kph
Robert is a great video host, feeling like i want to watch some junkyard wars now! haha
Just an advice: Use the microphone in mono to get a better speech quality.En keep it closer to the subject in noisy or reverberand rooms.
Thank you. I enjoy your program very much.
Best wishes
Staffan
All I can say is one word, amazing!
The motor technology shown here is truly exciting. Electric motors have always been impressively compact and light compared to internal combustion engines (it's the power source that's the bulky bit) but these are amazing. A motor with that power and torque which weighs 25kg!!
As Robert says, they need no gears whatsoever as even the differential effect can be achieved electronically with motors driving individual wheels.
The no gears thing seemed very well explained to me. U-joints and shafts seem the best way to connect anything to the wheels of a car, IMHO.
pls give us an update!!!! pls pls
In case you haven't seen it in other videos, Ford's Mach E uses multiple Yasa motors! Truly cutting edge stuff
I can't believe the size vs power output! They have to be the smallest and most powerful for their given size that I've seen.
I remember Jamie Hyneman(?) from Mythbusters doing some experiments with Neodymium magnets, but **ULTRA Strong ones and the attraction/repulsion of those was unbelievable.
Axial Motor Generator, right? Nice! Love it!
love this man always follow him and i love electric car.... sadly we dont have any in india
It is *_remarkable_* how far EVs and renewables have come in the six years since 2011 !!!!!
(FullyCharged production values seem to be the only industry that's able to keep up !!)
I love and enjoy every one of your videos. Thank you so much!
I wonder if the whine of high performance electric motor accelerating will eventually have the same cachet as the growl of a V-8 does now? Perhaps they will simply engineer the sound as they do with many of today's sports cars? Lastly, many bicycles today use in-hub constantly variable gears/changer. I wonder if it's possible to apply the same concept on in-hub electric motors to convert the torque. I love the idea of in-hub motors.
And how much electric is used each day to refine that oil? The answer is a lot , you can plug in anywhere but you can't get petroleum at home, Ect.
Robert's film is from 2011. Please see www.yasa.com for up-to-date information.
Been watching your vids for a while, just like say great show! Keep up the good work.
How did I find this video?
Ok. I've been thinking that people are only focusing on the batteries... What about the motors?
Then I started to find some news about axial flux motors. A "new tech" that's more efficient... And I see this 10-year old video about it.
:)
The new development like Rolls Royce using it and breaking records made it even more interesting.
Really nice lightweight modular design,
@yyarross they both will need to maintain the same torque and general speed to keep straight, but in a corner the outer wheels need to spin faster than the internal wheels to allow the car to go around the corner properly, thats why most cars have rear diffs instead of a solid rear axel
Always wanted an electric compact high output motor to do a conversion on a motor scooter.
Might need to beef up the chassis and brakes as well.
No mention of voltages needed, I'm assuming 72 or 144?
If the price could be kept at under $1000 for the 16kg 200kw 2019 version, then Yasa a will sell millions of the units.
7:17, so funny, i was completly inmersed on his talking, but suddenly Ouhh!!, made me laugh hard.
@LosDTenaces they don't need diffs if those motors are used in the wheel hub - some electric car designs use this technique. Note that they ARE indeed "small" motors, so it's feasible.
But granted, i doubt that's how the engines filmed here are going to be used.
cracking little video, Its like you've brought back "Tomorrows World" for the 21st century! 10/10
Good luck to YASA motors too. GB doing what we do best Innovation and high end engineering. Good to see.
@DanFrederiksen actually with some quick googling 4th is usually about 1:1. 1st is closer to 4:1 (1/4 the speed but 4x the torque). An EV doesn't need the gearing because even at very low RPM it has the torque needed to move the car quickly. Adding gears would just reduce efficiency. The only place you might want gears with an EV would be for very large vehicles like say a bus or a delivery truck that has a heavy load. Since you can add more motors it wouldn't be necessary but might be cheaper.
28 SEPTEMBER 2021 Mercedes-Benz has acquired electric motor company YASA, giving it access to the UK-based operation’s axial flux motor technology and expertise.
I wonder if these are the motors in the Aptera? Might be time to revisit this company now after over ten years of major changes in the EV world. I'd love to see how far they've come. I saw on a Lesics video they might be doing aviation, because of the impressive power to weight of these motors.
...love it when he starts and says, that he will do the 0-60 test "completely unnecessairy - but I am gonna do it anyway." can´t stand it : )))
Imagine if I had one of these Yasa motors in my Electric Go Kart!
@DanFrederiksen
Offcourse, with an electrical car, you don't need a full gearbox, and you could indeed make a smaller motor with a single gearing on it (no shifting). But then you sacrifice top speed, because the motor would run out of rpm's, or overheat, or suffer mechanical failure.
With a full geabox, you end up with at least 6% loss, added weight, complexity, and expenses. Which may offset the very savings you were looking for in the first place.
So, Direct Drive have many advantages.
@DanFrederiksen
You made a generally question regarding why no transmission, and the simple answer to that is, higher efficiency, less weight and less complexity.
A normal manual transmission will loose you about 10% of your power, and an average automatic will loose you about 15%, between engine and wheels. A *bad* automatic transmission in poor condition is a whopping 20 - 25% !!!
The savings while cruising with direct drive, more than makes up for the extra power used wihle acellerating.
@LosDTenaces
Having made actual tests with RC controlled cars with hub motors, I found it fairly trivial to link the two speed controllers of each motor with the steering servo, so that they would not break traction.
Basically goes like this - Turn wheels N degree left ? back off power by x amount on left traction wheel and add y amount of power to the right traction wheel. Simple enough, but takes a lot of testing to get the values right.
Gets more complicated with 4 wheel steer though.
(6:23) Fooling around with rare earth magnets with bare hands is not a good idea. They have a tendency to break like glass, creating razor-sharp edges that can cause serious lacerations.
You're so lucky to drive electric cars every day...
I should go to a Nissan dealer to make a little road test...
@XitUp magnetism is a tiny imbalance due to the motion of the electrons. when the electrons move (electrical current) their effect fade slightly due to relativity. it's not right but you can sort of think of it like a propeller becoming less visible when it spins fast and the force from the protons dominate a bit.
that's why magnetism from a ring works out of the sides, not edge on. sideways the effect combines. edge on there is motion towards you and away from you so net zero force.
wow took them more than 11 years until they got something out of it, partnering with MB. Though Axial flux is nice, it is easy to make but requires huge diameters to make it powerful for EVs
@RealitysSuccessor actually you should google a little further :) 4th is about 1:1 in the gearbox but a typical car is two stage gearing. don't forget the diff
AC 3-phase synchronous motors seems to be bettter than AC 3-phase induction motors. They have a higher size/power/weight ratio and a better overall efficiency (about 95%).
This motor is installed in the mustang mach-e, they are producing 1400hp and crazy torque
I love this show.
This is sweet! How are they getting that much power?!
I like it! Just curious though, what about heat dissipation with 6 or 7 times less mass? Is there an issue with premature stator or rotor wire insulation failure? Edit…this is an old video lol
Any figures on the amount of energy that can be recovered by regenerative braking with these things? A while back, I heard the state of the art was about 30%.... would be brilliant if that could be improved.
i am in Ethiopia so i can not find access here please?
@DanFrederiksen So you would drive a 3 cylinder petrol car, even though you hate them? Seems very strange.
How do you get to work? Do you live within cycling/walking distance?
Indeed, magnety things are the future!
@fullychargedshow Thank you for explaining that clearly, sorry for shouting in keyboard font. I only have one question, with differentials in the front or rear of normal cars, their differential allow both wheels to move at different speeds when going around corners, while keeping the same speed strait. But what sort of system do these electric cars have because they have 2 independent motors on each wheel, but obviously they need to give the same power otherwise the car would be out of control?
Quality journalism
First thing is that electric engine generate almost same HP in all rpm range, and in the same time petrol motor need around 3-4k rpm to get his nominal amount of HP. Second thing is that energy circulation loop - acceleration- deceleration is known quite long time, and that is a problem for controller, not for engine ( engine unit is only chassis with electromagnets, disk with permanent magnets, and hall effect sensors to give info to controller about shaft position in motor because its need to be sequenced) So its can be easy use as a motor and as a generator. (It is possible to get some voltage pics coming from motor, when is accelerating, so it is also generating power even when is use as a motor only) Third thing is that we have giant problem about storing electric energy. You can store way more energy with one liter of fuel than one kg of batteries. Four is that wee are so green but generating electrical energy is still very poisonous for enviroment and very primitive in the same time, same like using petrol... Impressive about electric motor is only amount of power generating by that tiny motor, noiseless and fact that you need much less oils and parts to keep thing running.
good show. yasa motors are certainly interesting but they don't seem to want to sell the things.. price and availability would be interesting to hear about.
also why they have no hub..
and if they have so much torque, why not gear them anyway. why lose all that torque density on the herculean task of driving the car directly.
4th gear on a typical car is about 4:1 gear ratio. this is 1:1. 4 times higher gearing than 4th gear. it's extremely high gearing to start out on
@Jesus45U the tesla roadster has a 1:8.27 fixed gearing and over 200km/h top speed. yasa proposes a more than 8 times higher gearing. surely 1600km/h is not strictly speaking required.
they are currently producing a 32k$ drivetrain that'll only do 0-100km/h in 6seconds with a 1000kg car. that's not good. I think a 1:3-1:7 fixed ratio is interesting for them. for 1:1 they will need to make their motors much much cheaper
Yes!! Full scale brushless motors!! Now it gets serious.
Love this show Robert
@DanFrederiksen Seems very strange to despise a particular engine configuration. If you don't mind me asking, what do you drive?
Can you imagine a motor directly connected to the drive train….
Me: Yes I can imagine a catastrophic failure without it having a clutch that allows free spinning. Ahhh the best idea of seeing a vehicle traveling at 60mph (96.6km/h) suddenly stop for no reason at all.
How much did just the motor only weigh?
750nm! 100kW! I need one of these as a hub motor on my motorcycle!
So what happened to this motor?
I thought the acceleration in my EV was better, but I realised your speedo is in MPH, not KPH.
In which case, you win.
Bugger.
Are they working on a 40-60 hp. motor for ultralight aircraft ?
Oil isn't "running out", but electric motors are cool. They will dominate only if batteries can advance.
Is this motor use for electric motorcycles
Where can I buy these Motor and what are the price ?
Induction used for cooking and Manson engine design and you can create a electronic rotary engine you can throttle. Novartis
How much do they cost, and where can I get one?
If these motors are located at the wheels, then one would hope that they are light enough to keep the in spring suspension masses low, otherwise momentum and inertia will be a major problem going over the bumps. neat ideas though.
Very few cars have in-wheel motors for this reason.
@DanFrederiksen
Driving in frisco will only be normal for people in frisco though.
Stronger acceleration can actually reduce range, depending on how you engineer it, I will agree though, that not all solutions will do so.
And yes, 32k$ is a significant amount of money under any circumstances, but I suspect that could drop with mass production. I believe the main reqason why it is so expensive, is because they are trying to recouperate development cost, rather than just the materials.
@DanFrederiksen2
Right, because San Fransisco is representative of the type of driving normally done.
Imagine that you put some nice big 18" wheels on it from a Corvette, with Direct Drive and cruise around at 26 mph (approx 200 rpm at wheels, 40 kph in metric), and as long as it doesn't require more than 250 nm of torque to go up the hills in an average city, it would *still* break 80% efficiency.
Be honest here, how often do you need better than that ?
Most cities are flat after all.
Excellent reporting on how magnet-y things push against ferrous iron-y things! Speaking of irony...
I stopped keeping up after the Lynch motor! Some went into battery powered boats .... they had bags of torque!
These new electronic rotary motors can be in each wheel leaving lots of space for support components. IE heating and cooling cargo and much more. Lite metal construction can be used to improve the vehicles function. No more fossil fuel use. Novartis
does electric gets more efficient when its rpm gets higher or lower?
So its been 8 years since this clip and this company is still virtually a mystery , loose clips hear and there no price,s etc.
Typical PhDs...
Will that work in a 1991 Ford Ranger, and how would I mount it in?
Actually guillermo, I think there is plenty of proof that electric motors exist, and that they work. Perhaps you were confusing what they were reporting with something else?
There was nothing particularly controversial in what they were claiming. Just an electric motor that works on the same basic principles and other electric motors, but which is compact and relatively powerful for it's size and weight.
Inspiring. Components to build the Plug In Hybrid SUV of my dreams are comming fast. Please BMW assemble them in a reliable and safe SUV, say an X6, or better a future X4. Just pick a clone of the 71KWH battery of the RR EV (Assuming 3 x folds Instant Power as well as 3 x folds capacity vs the Leaf), plus 4 of these electric engines, pull all geabox & other transmissions, and add a Range Extender pure generator = best for constant speeds (Micro Gaz Turbine ?).
Fit that all into
750 newton meter = 553 pound feet of torque !!!!!11 Thats staggering amount of torque considering an equivalent gasoline motor would be like a supercharged V10 engine !!!! Insane amount of torque from such a small thing ..... I dont understand how electric motors can be so powerfull .
