you know the kind, no rotor winding, bronze bearings, on every kind of
fan from desk fan to window fan to A/C fan to dehumidifier fan to vent
fan, where the bearings always gum up after two years and you can't
get enough oil into them to get them back to life, so first they have
trouble starting up, then they get slower and finally burn out the
windings.

Anyway, isn't there somewhere a person can get a decent replacement
with decent bearings? even (wow!) ball bearings? or some design with
an oiling port?

or failing that, a source for dirt cheap replacements where the cost
is as low as the quality so I don't have to keep ordering replacement
motors for the dehumidifier every two years for $30?
