Anyone can decipher this noise (new bafang hub motor)

Hello!
Wifey got a new bafang hub motor from dealer after long story, no need to go into that. It's a brand new bafang bfswxb36v250w185r 700c.
It's not the same motor that was fitted originally, but those are not sold any longer (she bought it two years ago) apparently.

Anyhow. It's making strange vibration/noise, that on the high end turns into a more metallic scrape noise. Anyone knows what it can be? Or is it no issue?

Recorded a video (please note I'm rolling the wheel, so there is also some chain noise) on full power.

Thanks!
Henrik
