Is it normal for a small motor like is on the fan to run hot? This one is running
about 200F. (taken with thermoprobe on a volt/ohm meeter with the probe on the out
side of bearing housing over the bearing.)


Measure the temps at other places in the motor. If the field windings
or iron are excessivly hot you may have a shorted winding.

Several have mentioned the possibility of shorted windings.. Depending
upon how long that motor was "stalled out" when Keith noticed the
problem, might that not be the problem now? If the bearing/bushing
seized up and let the motor cook long enough, simply freeing up the
bearing isn't going to do much if the windings have now become a "hot plate"

Any idea how long that puppy was powered up and just sitting there
groaning, Keith?
