A typical-looking fidget spinner, but with a motor in the axle - so it can spin by itself.

Could be powered by cell batteries in the symmetrically protruding nodes of the spinning section.
Or it could be wind-up, clockwork would also be good.

       So like a mechanical Top?

       [+] one of these would be exceedingly satisfying to hold. Bonus points for having them spin so quickly they impart a sense of mild dread in the holder. A pressure-sensitive button in the centre might be used to regulate the power-assist.

       //If you google battery driven fidget spinner you’ll find plenty.//   

       Your linked video is reasonably close, but it doesn't fit the spec, if you read carefully.   

       I did actually google this before I posted, so y'know.

       //Where does it miss on the spec? "Typical looking?"//   

       Yes.
It needs to look very much like a standard 3 or 5 lobed fidget spinner, or it's nowhere.
