I have an old split phase induction motor that runs quite well. Especially considering the fact that it is at least 60 years old. But it makes a funny sound when running but the sound disappears immediately whe power is removed. It sounds like something is a little loose. Sorta like if the shaft was oscillating back and forth between the thrust bearings. But it is not that. My son suggested that maybe one of the windings is loose and rattles a little back and forth when the polarity of the AC voltage changes. Anybody got a clue? Thanks, Eric
