I had occasion to dismantle a cheap pedestal fan the other day
(Coles
Home
Collection). It hadn't failed, but I wanted to see how it was
wired up
(that's another story).

Curiosity, good! I'd hire you as an apprentice at my pinball shop.
That's not going to fix the problem of the blades being stalled.
Not sure about 'stalled' here, unless the gearing is designed to not
allow reverse direction I am having trouble understanding the problem here.
What I would really need to do is fit the one-piece fan blade assembly
on back to front (as well as reversing the motor), but the fan blade
assembly is not designed to be attached the other way around.
Sylvia.
Might sound silly, but cant the entire fan head (including motor) be
rotated 180 degrees, or do you want the
air intake without the motor in the way ?
The application is to suck cool air in through an open window at
night. During the recent heat wave, it was noticeable that even
though the temperature outside drops at night, the temperature of the
house doesn't drop that much. The problem is lack of air
flow.
A conventional pedestal fan blows in such a direction that when it's
placed as near as possible to a window, the fan blades are
still quite a way from the cool air, and so the result is not as
effective as it might be. If I could reverse the direction of
flow, then I could also turn then fan around, so that the blades
would be much closer to the window.
Stick the fan outside, blow the air inside. Lateral thinking is absent
in the female of the species.
(to previous poster) Right, no lateral thinking in the female of the
species? Explain that to Madame Curie, Margaret Thatcher (OK, not a
great example), my daughter (5 year physics and math major), and so on...
We could also mention Anna Bligh, Christina Kennealy, Julia Gillard if
you want
the opposite of that.
No worries, though it's 10' above the ground. I'll just cantelever out a
shelf, and a shelter (fan's not waterproof, and weather forecasts are
not sufficiently reliable), get a sparky in to do the weatherproof
electrics (which I could do myself but am not legally permitted to in
this Australian nanny state), and it'll be fine.
Sylvia.
You can't get a permit to do your own home wiring in Australia? Pity.
Here in most of Canada - as long as the city (or relevant jurisdiction)
electrical inspector OKs the job (permit required) - then the handy
homeowner is permitted to do their own work - obviously one does it to
the electrical code. I did quite a bit of improvements to my previous
home, the inspector came in, examined a few random spots (opened
sockets, boxes, etc) and like what he saw and signed off on the job. If
he wasn't happy I would have had to open every box to show the job. This
inspection was before I put the wallboard up of course!

Not here, it is a closed (union) shop - with "jobs for the boys"
This has been going on for the past 40 odd years (in QLD)
that I am aware of, and probably longer.
Having said that, electrical fittings are readily available for sale
to the public through
pretty much all hardware stores, as well as a more limited range in
many supermarkets (plugs, power sockets etc)
I know of one totally unlicensed electrician locally who openly does
work for people and commercial premises (for cash in hand). Has the
attitude "have no assets that can be taken, so cant be sued".
There is 240/415v involved whereas Canada is 120/240 IIRC.
