These motors have no brushes, slip rings, nothing.... I think once the bushing goes bad, they get hotter than designed for and the shaft expands and binds up. In addition to this, the coil seems to get hot as well, and it looses power to turn, stops, then gets more hot. After it cools a while it will run again for a while until it begins the binding process again.... I had several do it, including a window fan, where that one acts the same.... Both motors have only a coil and solid core armature, no wires, no slip rings, brushes....
