Chosen Solution
I disassembled my floor fan because it was making a grinding noise that wouldn’t let me sleep. I then proceeded to lubricate all attatchments, as well as the gearbox (cleaning it all up, of course), but the noise persisted and I found out that the electromagnet in the middle is grinding the coil. Since the shaft of it is supported by two attatchments (they pivot if you move the shaft on one end to the side), they supposedly stay leveled when the shaft is spinning, but even so, the electromagnet in the middle grinds the inner sides of the coil. What can I do to fix this?
@swansondisciple my concern would be the bearings and the alignment off the front to the back bearings. If either one of those bearings is not true or worn etc. it could cause the shaft to wobble. See what you can find on that end of the motor.
