UK-based YASA has just built a tiny electric motor that makes Tesla motors look like slackers, and this invention could potentially reshape the future of EVs
That motor doesn’t look like it has enough mass to properly make enough torque to drive the weight of a car even if said car it made entirely of carbon fiber
Totally, and I think that’s why they thought it was worth a press release. In the article they go right to how they’re setting a new power density record with this design.
Electric motors are just really power dense. The article says they managed a short term peak of 1,000 hp with that little flat 12.7kg motor and the continuous output could still be half that.
Just the cooling must be crazy.
Out of curiosity I looked up something comparable. It looks like high-performance integrated drive units that have other stuff like the single-speed gearbox, differential, and inverter are still only in the dozens of kg.
