I posted a picture of the squirrelcage motor in my homemade "air filtration
system" with 18x24" filters. The motor has started to make a high pitched
squeeking noise, and the center circular pieces in the picture (bearings?)
are getting hot. Is there any way to lubricate, or salvage the motor, or
do I need to get a new (used?) motor? This thing has had many, many hours
on it, since I use it too to circulate the air in the basement. So I owe
it gratitude, but can afford another motor. OTOH, if it can be saved
somehow, that would be good. But I don't want it to catch fire!!!

Any advice is appreciated!
