Is there anything I can do to get the electric motor for my favorite
desktop fan to start up properly again?
how are the bearings? Does it turn freely? use sewing machine oil
for lubrication. use wd40 if you want to ruin it.

are the brushes and commutator visible? signs of wear?

If it's a cheap POS, you should just replace it.

99.9999% sure it has no commutator or brushes. Because about 99.99999%
of fans don't (except blower motors in automotive heating and
airconditioning systems - which are technically blowers, not fans.)

If automobiles had an AC system instead of DC, then they too would
have no commutator or brushes. But they don't. So they do.

Where do you get "automobiles" from any of this? The other person
said *except* automotive heating & AC.

OP described the motor as belonging to a "desktop" fan. Therefore a
common garden-variety induction motor, therefore no brushes. Sheesh.

Sheesh yourself, what is the big deal? I was commenting on why the
blower fans in autos have brushes.

OK; I guess my trigger's been set pretty low lately, as there seems to
be more than the usual Usenet bull**** flying around.

I'll get over it. OK, I'm over it.
