Click "More" and scroll down: "In contrast to conventional radial flux motors, the electromagnetic flux in an axial flux motor runs parallel to the axis of rotation. The key components are arranged in a disc‑shaped layout: two rotors sandwich the stator from the left and right. This design enables an especially compact motor architecture, high power and torque density, and new freedoms in drivetrain packaging. In the…

No, it means the motor is smaller and it can be put into the wheel

The issue with this is, without an expert, how do I know I am getting an accurate representation?

You don't. You didn't know before either. The difference is trust. How do you trust it as much as you do the hypothetical humans making such representations? That's up to you.

I think humans develop expertise and brand names and get called out when they make mistakes and if they are too wrong, their reputation is damaged.

This doesn’t seem to apply to AI for some reason. It keeps generating incorrect results after incorrect results, yet people continue to trust its output.

I don’t know what to make of this.

The translation's a little woolly. For the AMG GT4 there will be 3 motors: two at the rear, and one at the front. My interpretation (and my German's pretty lousy) is that each motor is combined with a gear system in a single package, and they're calling the overall package (motor plus gears) a High Performance Electric Drive Unit (HP.EDU). The two rear motors will probably be independent, so no need for a mechanical…

In terms of traction control, does this translate to something between "4WD" and "AWD"? Or is it orthogonal?

I'm not sure that the traditional notion of traction control applies, given that there are three independent suppliers of power, so you don't necessarily need the mechanics of diffs and computer-controlled brakes to provide maximum traction.

What would it mean to "turn off" traction control in a car with independent motors per wheel? (OK this is a 3-motor/4-wheel scenario, but hypothetically…)

With software control and independent motors, we're likely to see increases in low-traction capability (for the right price-point and probably aimed at particular buyers)

Mercedes acquired Yasa (UK) couple of years ago and now getting up to the speed in the production. Here is a nice video that explains axial flux motors with a factory visit https://youtu.be/B2Hl4c1iZK0?si=VfDYARyuaPVj1nKm They are so, so, small.

I was curious how this thing works and asked Claude to visualize it -- mostly to see how good Fable is and I have to say, what it made was good enough for me to get a gist of it. Posted it here https://azimi.me/axial-flux-motor-explainer/

Honestly, I don't think this actually provided much above a paragraph of text.

The visuals didn't show much, and I learnt a lot more from one of the YouTube videos (https://www.youtube.com/watch?v=dCO633KE7RA) posted below.

It's neat that a whole interactive deck can be produced without effort. But it's just not very interesting.

I mean in EV's, a fancy expensive concept motor isn't going to help, autonomy should have been their direction 10 years ago, they are on the downward slope of their existence im afraid. Its the equivalent of Blockbuster adding a tape rewinding service to try and boost sales vs Netflix streaming.

That is also not guaranteed. VW (with its array of brands) leads the european BEV market by a lot. [1] (sorry I only found data for April 2026 right now but earlier months were similar) One additional point of data. In Q1 of this year they delivered 200K BEV worldwide [2] while Tesla did 350k [3]. Calling that 10 years behind is not warranted in my opinion. I would agree to say competitive and challenged. [1] https:/…

Volume alone is a bad metric, Tesla makes profit on their EV's sales Mercedes makes a loss, not sustainable.

Only slightly related but does anyone know anything about motors with magnetic bearings? As in, no contact or friction. I'm looking for a hardware project

I think air bearings exist? Maybe some prior art to consider

> develop and iterate leading electric vehicles so fast. How do you know this for a fact? Chinese press releases? You've driven one? Some auto blogger drove one? After world war 2 Gorbachev or whoever visited the United States and during that trio visited a supermarket. He thought it was a facade, possibly, put on just for him, there's no way Americans are this prosperous (or whatever, this good at agriculture, farm…

I am somewhat confused at the intensity of pushback for the statement “leading electric vehicles.” Chinese EVs are leading and that doesn’t necessarily mean being the best, most advanced vehicles. They are leading in value/pricing, and in many regions they are leading in sales. BYD sells almost double the EV volume of Tesla globally as of December 2025. They are objectively leading in that respect. I think the parent…

I wouldnt be so harsh even with chinese combustion engines, its at this point a meme that is just copy pasted because everybody says so, but without actual experience. People dont understand how China is 3x bigger than Europe and 4x bigger than US, the scale of that market is absurd and competition numerous and fierce.

I've had MG suv rented recently with just gasoline engine and it was fine. This comes from long term bmw driver, they are not on the exactly same level, but light years ahead from similarly prices ie french vehicles. Handling was fine too, probably the biggest shock for me, this is where french, italian etc are losing me (bmw effect). And they cost 1/3 of bmw.

I wonder how developing electric motors compares to combustion engines. My hunch says that it’s the main reason the Chinese high-tech electronics industry was able to develop and iterate leading electric vehicles so fast.

The new season of Formula One feels (unfortunately) like Formula E!

In Formula E the drivers control engine behavior and regen. It is much better than F1 right now.

Tangential, how much regen can this system support? For example, can a car with 200kW propulsion have a 400kW regen (Tesla has upto 65) and are cost effective like friction brakes?

All motors are generators. It's only a matter of how you are creating the magnetic field with the stator windings.

In order to generate a higher regen, you'd have to somehow get more energy in the motor first... and since its only rated for 200kW, good ol' physics limits you, IF thats all the energy you put into the system.

If you roll it down a hill, or do something exotic like inverting the magnetic fields .... you can exceed the motor rating. But thats usually not recommended because the motor driver itself isnt rated to handle that power.

I'm not saying there isn't room for innovation but... Electric motors have been around for a century now already in many applications. It's not like the Dawn of the steam engine

According to wikipedia[1] the first industrial steam engine (1712) was invented almost 100 years before the invention of the steam locomotive (1804), arguably its greatest evolutionary feat.
