Bought a cheap "5000w" motor off aliexpress and it ran fine for the first ~50 miles. Last weekend I went for a longer ride and pushed it a bit. The motor overheated and now has a lowend rumble growl video link https://photos.app.goo.gl/rfrfoCdUhqJkDJrr5 Opened up the hub and found the attached photos. Anything I can salvage? Could I just buy a new stator/internals? Thanks for the help.
