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.😂
YASA Flux motors came up on my feed and my UA-cam search brought up this video - fully charged was there at the beginning :) Good to see this is being used in production.
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!
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!
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.
@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.
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.
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.
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).
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.
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
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.
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.
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 UA-cam. Peace vf
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 !!)
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.
@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?
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
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.
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.
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
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.
@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?
@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
(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.
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.
@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.
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.
@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.
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.
An electric motor and an electric generator (dynamo) is the same machine. Electric machines can change the power flow at a whim. So they go from generating mechanic force from electricity to generating electricity from a mechanical force and back, as required at any given point.
On that particular test bench they are running one unit in generator mode and the other in drive mode. Often in an electrified car you'll have the exact same unit doing both because you're unlikely to be braking and driving at the same time. As the guy explained, this just makes for a compact testing setup, connecting two.
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.
@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.
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.
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.
@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.
omg love it.. thought of a motor like this so long ago, i thought of it like a maglev train on a circular track the size of a wheel. Never could find one that matched what i was thinking nice to finally see something. Now they just need to use graphene, should improve weight cost and be able to 3d print optimal designs. Then you can make electric planes.
@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
@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.
@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.
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
@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.
Working on motor that can get 80-90% of the fuel out. It is a distributed IC engine. One motor is 6 inches diameter by 12 inches and weighs 35 lbs. 84 hp at 8400, can go to 12,000 rpm for peak 120 hp, just like the electric motor shown. About the same space.... 80:1 expansions. Can run on solar thermal and battery (electricity) at 45%. It can also do boundary layer active drag reduction as well as power on lift for 10 CL on wings. Land at 1/2 speed. It can go in car or roadable airplane. Range 2100+ miles on Natural Gas at 100 mph. $33 in fuel to go 2100 miles, or 200 mph at 10 cents/mile on gasoline. 1 cent/mile at 100 mph on Ng at $1/gallon equiv. In contrast, electricity is 15 cents/kwh in USA and 25-30 in Germany. That is $5/gallon. Battery is 12 cent/kwh to use it or $4/gal. That is $9/gal. Then you add in boundary layer....allowing a car to get 200 highway and 400 city. No idle. Can dead torque like an electric motor. This can use Ethanol, Gasoline, Diesel, propane and battery if wanted. This engine can also be 24/7 and distill water via vapor compression distillation.... Heat, cooling, water and power. All that a house need, 24/7, all from NG or solar (80% of the time). There is a better way...
i love E Cars. They are not only the environmental solution for save the world. when more people should decide to buy one. but they are also very beautiful and special cozy designs. hope in near future there will be only E-cars on the street. the planet is only to save when all people do not think too long and decide quick !

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

But granted, i doubt that's how the engines filmed here are going to be used.
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
Quality journalism
Excellent reporting on how magnet-y things push against ferrous iron-y things! Speaking of irony...
Is this an Axial Flux motor?
@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.
I need 4 of those motors put in my Hummer with a generator where the motor was.
Didnt it have a generator also?
Lol ... Why not just bolt one of these yasa motors to the back of the current engine an bam you already have a generator 😂
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...
Awesome design - modular - put 10 of those on one axle for a freaking bulldozer or something. It would have to be a big decent axle at that.
Watching this video in 2021 👍
...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 : )))
750nm! 100kW! I need one of these as a hub motor on my motorcycle!
Working on motor that can get 80-90% of the fuel out. It is a distributed IC engine. One motor is 6 inches diameter by 12 inches and weighs 35 lbs. 84 hp at 8400, can go to 12,000 rpm for peak 120 hp, just like the electric motor shown. About the same space.... 80:1 expansions. Can run on solar thermal and battery (electricity) at 45%. It can also do boundary layer active drag reduction as well as power on lift for 10 CL on wings. Land at 1/2 speed. It can go in car or roadable airplane. Range 2100+ miles on Natural Gas at 100 mph. $33 in fuel to go 2100 miles, or 200 mph at 10 cents/mile on gasoline. 1 cent/mile at 100 mph on Ng at $1/gallon equiv.
In contrast, electricity is 15 cents/kwh in USA and 25-30 in Germany. That is $5/gallon. Battery is 12 cent/kwh to use it or $4/gal. That is $9/gal. Then you add in boundary layer....allowing a car to get 200 highway and 400 city. No idle. Can dead torque like an electric motor.
This can use Ethanol, Gasoline, Diesel, propane and battery if wanted. This engine can also be 24/7 and distill water via vapor compression distillation.... Heat, cooling, water and power. All that a house need, 24/7, all from NG or solar (80% of the time).
There is a better way...
i love E Cars. They are not only the environmental solution for save the world. when more people should decide to buy one. but they are also very beautiful and special cozy designs. hope in near future there will be only E-cars on the street. the planet is only to save when all people do not think too long and decide quick !
