Comment on 28-pound electric motor delivers 1000 horsepower
Sam_Bass@lemmy.world 1 week agoThat 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.
