BMW also makes rare-earths-free motors for their EVs and - at this very moment - theirs are far more advanced. They offer almost twice the power (up to 300kW vs 160kW) and are on a 800v architecture.
The cheapest EV model Renault sells is around €20K, the cheapest BMW EV is around €65K. It's safe to say the companies are not in the market bracket, no?

Re: Electric motors with no rare earths
#22Mentioned in another HN thread [0]: They're also used by Nissan [1], BMW [2], and Indian EVs [3]. European firms like ZF, Valeo, MAHLE, and Schaffler along with British firms like AEM have been working with their Indian JVs as well as Indian players like Sona Comstar and Sterling for a couple years now to integrate supply chains for mass-producing EESMs. EESMs as well as the larger OEM story played a role in helping…
does Nissan still use these motors, the car in the linked article has been discontinued, and then only real info I can find on their site about the leaf is about their ROCKIN' bose sound system/s
Re: Electric motors with no rare earths
#23How soon to see rare-earth-free paired with CATL Sodium batteries? Seems a price war, range war is imminent.
Could be wrong, but AFAIK the CATL Sodium batteries haven't yet hit LFP pricing. You are unlikely to see a vehicle with sodium batteries until after that happens, and it needs to be significantly less than LFPs as you Na batteries have more weight per Wh. I believe they also have a shorter lifespan (but not NMC short). Edit correction, looks like CATL is promising 15000 cycles, which is much longer than LFPs which us…

One of the most interesting features of sodium batteries is that they still perform good in cold temperatures.

#30https://youtu.be/FHufjrP0xDI?is=xmFQrXGa1dBHM67I This is a helpful explanation of what this technology is and looks like. (Munro)
So. Analog presentation. Actual motors on a desk with a flip chart. No animations. No internal visualizations. One page had diagrams that would have been better super-imposed (or hey, animated). Then one page the begs questions with no answers given.
