This article doesn’t explain anything innovative. There are plenty of motors around, using “wireless induction” (as opposed to some other kind of induction?), operating at very high efficiency.
> The two companies aim to cut overall carbon footprint by more than 40% as compared to a permanent-magnet e-motor with equivalent power.
Modern motors, with or without magnets, are efficient enough that saving 40% of emissions isn’t going to happen. (Or maybe they mean sometime strange by “overall carbon”).
- CorrectHorseBat 2y agoI think they mean saving 40% of emissions on production of the motor
- euroderf 2y agoThe article does say "lifecycle carbon emissions".
- zarq 2y agoThey seem to be saying that the absence of rare earth metals makes the overall lifecycle carbon emissions be 40% lower than those that do use these metals. It does not seem to be related to the efficiency of the motor per se.
