Most rewinders just use a single motor. They are pretty cheap pieces of hardware. I have several.
However, they use a less powerfull motor than vhs decks.
Keep that in mind, since using a vhs deck motor you could cut or broke a tape. I have.
My recommendation, if you want a device for cleaning and rewind tapes: use a Panasonic J series deck.
J40, J45, J46, J48, there are several models (it varies deppending on continent/zone).
The J mechanism is different from regular decks: when FF or Rewinding, the tape IS NOT on the head. It takes it away from it to prevent wear. This allows you to rewind and clean the tape in the process.
I recommend having one just for this purpose.
