Everything but the Metric System: “The new YASA axial flux motor weighs just 28 pounds, or about the same as a small dog.” :)

If I were a self-respecting journalist, I would've used 3.26 gallon milk jugs. Small dog automatically goes to which breed? Chihuahua (fits in a toddlers purse) or Border Collie or Golden Retriever or Saint Bernard (needs an SUV/minivan)? 4 different classifications based on size!

Americans do not do metric. Americans can’t even balance a checkbook. Hence the small dog reference for mental “clarity”. We’re dumb. Just look at the news…

Sure but don't they have a mental image for 80 feet for example? Why articles will almost always include something like "that like 50 chairs put next to each other" when length is mentioned.

If you were to say 100 yards, we could. That’s a football field (American football played with your… hands).

Because people in the south don’t even know the imperial system… it’s bad. They say things like “Take the road there yonder and when you see the white church, turn right, go a ways until you get to the dirt road…”

Anything outside of what they have with them, they don’t have a clue or can’t imagine it accurately. Small dog reference, there’s millions of Americans with a small dog so most just looked to their pooch when this came up. Same as if you were to say something like 50 cars. They would look outside to their Toyota Corolla and imagine 50 of them. It’s like talking to grown toddlers sometimes but that have full grown emotional states not under control. Not everyone is like this but a good 50-60% of Americans are. Just look for the Lululemon.

But EVs are already heavy because of the battery. I suppose percentage-wise the motors don't make much of a difference (?)

The issue with this type of motor is that it is part of the unsprung weight since it is inside the wheel. This is probably why savings here matter a lot more (or at least in a very different way) than the battery weight.

I might be wrong, but I don’t think these motors are intended to be used inside the wheel. That would add a ton of additional requirements in terms of physical durability as well as constrain optimal torque and RPM of the motor design.

The new YASA axial flux motor weighs just 28 pounds, or about the same as a small dog. But how many footballs a small dog weighs?

Not sure about footballs but 28 pounds is about the weight of a child, a bag of rice, or a dumbbell. Hope that helps!

Europeans don't even know what it means to "balance a checkbook", so they must be dumber.

Yeah but ya’ll have estates…

> According to YASA, this is achieved without using exotic or expensive materials, so the design could actually be scalable once the demand kicks in. So, no rare-earth magnets? And it will be cheaper than existing motors?

Rare-earth magnets do not fall under “exotic”.

They are expensive.

I wonder if Americans don't have a mental image for measurement units so that they alway use some physical object as a reference. Sure, its useful to use a common object as a reference but I don't see that much often in other places. Most people usually understand what it means something to be 20 meters, 5kg or 2 liters intuitively. Like, when I hear that something is 60m tall I intuitively think if it as 20 story ap…

It helps to understand that the only freedom Americans only cared for (and the only freedom they have left from the looks of it) is the freedom to choose standards of measurement and vocabulary.

You sent me down a rabbit hole.

I have no idea, but:

I searched axial flow motor in wikipedia, and the last link is:

https://newatlas.com/technology/conifer-iron-magnet-electric...

So maybe?

I guess you're in the minority here. In Germany, everything Remotely large will be measured in football fields or "Saarlands".

Whats the speed of light in football field terms?
