I want.
 

If these work as well as they say, it would be really cool if they made these as a stock rotor replacement. Cheaper than a bbk.

I am quite skeptical of these claims in a real world application. It's basically a slotted solid disk with some fins on the inside radius. I think iron is quite thermally conductive, so moving more airflow to the outside surface isn't that important relative to overall airflow across overall surface area. In fact, you would wind up with a cool surface and hot core in this case, which is pretty much the opposite of what you want. There's also packaging issues, like you need a small hub-wheel diameter ratio to make the inner fins and outer waviness big enough to matter, while decreasing available braking surface and caliper clearance.

Mountain bikers already have such stuff...

That would be quite interesting!

Things might already be in the works:



Greetings Brian,

Thank you for contacting Orbis Electric. We are happy to inform you that Orbis Wheels and Orbis Brakes are both thriving under our new name, Orbis Electric, as we continue our mission to radically accelerate EV adoption and lower global emissions. The Orbis team is actively engaged in bringing our patented in-wheel-motor and brake technology to market in the coming year.

Our first product will be EV In a Box, a retrofit version of our in-wheel motor and brake assembly, capable of converting any existing internal combustion car or truck into a PHEV or BEV in a matter of hours. EV In a Box will adapt seamlessly with virtually all passenger and Class 1-8 truck wheels, with power options of 120kW/160hp and 420kW/560hp.

This game-changer is expected to be available in retail by 2025. In addition to developing dealer networks to serve our consumers, we are testing and meeting with global vehicle manufacturers and fleet owners to bring Orbis Electric innovation to the industry.

With regards to our brakes, Orbis is currently considering our distribution channels for Orbis Brakes. The founder of our company does race so it would make sense that we would step in there at some point!

We will be sure to keep you updated with product specifics and car model releases, motor sizes, and parts, geographical availability, and launches over the coming months. To be kept in the loop please sign up to receive our newsletter at: newsletter@orbiselectric.com.

Please do sign up if you want updates!

Thanks again for your interest. We promise an electrifying future!

Might be a good opportunity for Counterspace Garage. (Hint, Hint)

Even more unsprung weight?
Did thinking so hard boil their brain pan dry?

Might work fine for sub 15 kph golf carts I suppose.

I know unsprung weight = bad, but wouldn't this be offset at least somewhat by the weight loss in the body itself?

The biggest problem with in hub motors is the lack of isolation from vibrations/bumps/potholes. But yes, not good for performance driving either.

California startup. As long as they can make a nice pitch they can keep investor money rolling in to burn. Doesn't have to match reality, many people with that kind of money don't live in reality anyway.

It's certainly offset by conservation of momentum when the wheel breaks on the trailing edge of the pothole.
It wants to keep going one way as hard as it can even when there's an immovable object in the way.
Hardtail Harley. That sort of thing.

If they were to continue with a hub motor concept, it should be re-gen braking only and shuck the rotor and caliper completely.

Then when a terminal fails somewhere it's momentum all the way, electric steering & etc ...
