It would have been awesome if that article had, at any point, explained what an electric axial flux motor was, and why anyone might want one.

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…

Hand waving.

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 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. (Edit: My more clarified point is regarding the machinery required + place to accommodate them to work on electric motors vs. ICE metal parts and all the intermediary parts transfering power in the…

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

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 equipment, etc)

Also do the race cars have 4 wheel drive, or all-wheel drive? I'm wagering all-wheel with "torque vectoring" and "Yaw control", like a Mitsubishi Lancer Evolution X.

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

maglev but those do linear acceleration instead of rotational. seems tricky though for cars with such uneven surfaces.

Listening to the heads of the American and European car companies say the same and driving in them in china. I know that is different than personally disassembling one and reviewing it, but I am not sure the incentive for the other companies to say they have inferior products, unless it was a play for subsidies or deregulation of some form.

Personally I feel that the rest of the world continues to dramatically under estimate China’s progress and technological advancement at our own peril. Is there fluff and are their lots of untrue claims, of course, but that is certainly not something they have a monopoly on.

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 comment of yours made a good point (or at least adjacent to a good point) about China’s ability to enter the market: they can’t compete with 100 years of internal combustion engine development along with the vast parts supplier network of the West, but they can compete on battery chemistry, battery supply, motors, and the more vertically integrated EV space where automakers don’t need to depend on a huge network of parts suppliers like they did in the past.

I also think that a lot of pushback to the innovation that China is delivering is criticism that is stuck in the past. If you buy a Xiaomi car, it integrates perfectly with all your Xiaomi consumer devices. You can control your rice cooker or robot vacuum from your car’s integrated infotainment system. This type of approach was exactly what Apple was going to deliver before they abandoned their automotive project.

Or, you can buy a Mercedes and you’ll get a car with more precise handling and perfectly tuned driving characteristics. The infotainment system looks like Windows Vista.

Which side of the aisle do you think most consumers care about? I think most people buy into Xiaomi’s approach.

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/

what was the prompt for this, did you use a CAD/threejs skill or grab a model from somewhere?
