How many types of motors do we have in e-mobility? Let’s get acquainted with them.

Nice and cute car

Tesla underground, 15 Oct 2022Lithium, aluminum and steel are rare earth materials. lol No, rare earth minerals (known as REEs/REMs) are a group of 17 minerals including the 15 lanthanides (atomic numbers 57-71) as well as yttrium and scandium. The main one used in EV permanent magnet motors is neodymium. You are probably thinking of rare metals; they are not the same thing. https://geology.com/articles/rare-earth-elements/ here is a link if you want to learn more! :)

FarFan, 05 May 2022What about Switched Reluctance Motors (SRM)? No rare materials, almost the same efficiency as ... moreSwitched reluctance is a primitive version of a reluctance or permanent magnets synchronous motor. As cons it has very large EMI noise, requires bigger stator to not saturate the iron and worst offender of all is that torque has a lot of ripple.

What about Switched Reluctance Motors (SRM)? No rare materials, almost the same efficiency as those with permanent magnets, no extra overheating as induction motors, and no brushes to change. As cons, it is slightly heavier, it needs more expensive control unit (but pretty reliable), and little underpowered on start. But it is industrial standard for reliability, it can be towed (permanent magnets can't), and may be cheaper than any of listed.

My Renault Zoe (ZE50) has what Renault calls Externally Excited Synchronous Motor (EESM). I wonder what difference is there between that and the "Electrically excited synchronous motor", if any?

"The increased power density means high power in low volume, which is why permanent magnet motors are used exclusively in PHEVs."

This looks like a copy/paste from somewhere else, because this statement is no longer true for many years now.

Quite interesting article, on e- mobility fundamentals

what about axial flux motor
