My attic gable vent fan stopped working and so I went upstairs to find a plastic bag tangled in it.
It's this model:
I removed the bag, but nothing happened.
I unmounted the fan, took it to the garage, and found that power still gets to the motor, but... it just doesn't do anything. I don't see or smell anything burned. I don't see any fuses. Any ideas of whether/how I can fix?

IDK what kind of thermal protection they have, but it might be a thermal fuse.
If it does and you can find and test it, it might be blown. HD and similar
also sell replacement motors that I think run ~$40 that fit many of the fans,
but for that type fan, it may not make much difference in price or ease
of installation. For roof mounts, it does.

I'd check for continuity. Might be as Trader says,
thermal fuse. If the thermal is open, I'd be sure
to replace it, not just jump out. Might save you
from a fire, if the motor over heats the next time.

It's a tough environment and no one is going to see or smell
a smoking motor that's about to catch fire.

At least this flame didn't burn down the OP's house.
Bypass a thermal fuse.... might.

Yes. It also doesn't seem like a particularly great idea to call a local
company called "Industrial Motor" about a gable fan motor when the
whole fan is easily replaced and they also have replacement motors
available that probably fit at HD for $40.
But then it is HomelessGuy, so what do you expect?
I'm the OP.
Thanks for all the good technical advice.
I will definitely not be reusing the fan, as it's not worth the risk or the effort to repair. At least it's worth something for scrap.
Since you're in North Salem CT, you might want to call these people:
Industrial Electric Motors Incorporated
85 Shelter Rock Rd, Danbury, CT 06810
Between Jansen St and Cross St
And ask them how much a 1/8 or 1/10 horse-power attic fan would cost.
Most likely your fan is burned out, or the internal thermal fuse is
blown (and is non-resettable).
You could unscrew the 4 long screws and pry the case open and check the
windings. You might be able to find the thermal fuse (I'm assuming
there is one) and remove it (bypass it).
