Electrical Motor Question

So i bought the Jet 16/32 I mentioned in another post. I think I got a good deal but have a concern. The light on the smart sand box does not come on which didn't really concern me. What does concern me is: Even when unplugged the smart sand motor housing is magnetic. I'm sure this isn't normal but don't know squat about electrical and wiring and all that. It is wired 110v and runs, just didn't seem to move all that fast. I took the cover off the smart sand unit and the circuit board is NOT broken. Any thoughts or advice on how to proceed here?

Thanks...
