Most likely all the lubrication was gone from the shaft making it
really hard to turn. As long as you kept it on and hot it was able to
turn. If it can't turn at the speed that it's intended then the
windings get very hot.. The motors are protected by thermostatic and
current overload protectors, about 3/4" long. One of these breakers
triggered. It can give quite a pop. It's fairly harmless because the
only fuel source is the insulation on the wires. The shellac coating on
the windings was burning and that's where the smoke and smell emanated
from.


20 years ago I would have gotta a bit kick out of that post :P
