no, but requires introduces brushes (slip-rings really) which is a wear item

I don't think car owners have to worry about this the first half million miles or so with these motors. Electrical motors last a long time. We'll know for sure in a few decades, I guess. That's how long it will take for a significant number of their cars to actually drive that far.

Also, compare this to ICE engines which experience continuous explosions, lots of mechanical parts, extreme temperature swings, etc. and still manage pretty decent durability. There's simply no base for assuming that parts like this wearing out and needing to be replaced is going to be a common thing.

		The Continental and Renault motors like those in my Kangoo ZE and Zoe have so far proven fairly reliable, with the occasional exception being shaft bearings. The Q210 is particularly robust. I'm not aware of anybody having brush/slip ring issues yet.

Cars already have lots of wear items and a mature service industry for them. If I can reliably get at least 50k miles out of it, then I wouldn't be all that bothered, as this is not likely to be an expensive part or service.

		> mature service industry for them The car service industry is a scam, and I am glad that EVs require minimal to no servicing that cannot be easily DIY like tires and brakes.

		so apparently on the BMW i4s it requires a rear subframe drop which isn't going to be cheap (10s of hours).
