That is a more than plausible scenario.
Windings shorting to the can would produce exactly those symptoms.
removing the bell and inspection of the magnets would probably prove it one way or the other.
And a new stator would entriley fix the problem..assuming the magnets were not damaged and the bell still ran true..which a run out test on the lathe would establish..
