Hi,
I have a small 120vac house fan motor i was working on and all of a sudden it started acting very strange.
Without any power applied, the shaft turns freely by hand. When power is applied, the motor makes a noticeable hum and the shaft locks tight so it's very hard to spin by hand.
Nothing in the way of the armature or bearings, and it does turn by hand without power applied.
Anyone ever see this before?
