Do old hob filter motors have any use?

[Swiftwater]

I have 2 old hob filters that are missing or have broken intake parts and I can't find replacement anywhere, one of them is a cascade, other well the motor says askoll.

Are there any uses in old hob motors?

The motor of most HOBs just uses electromagnets to spin the impeller. Unless you can find an impeller that's a close fit, I'd venture a guess and say the old motors are almost useless.
