Hi,
Can someone please tell me if there's a small, *water proof* DC motor
available to buy which I can leave permanently outdoors? Even worse,
it will get splashed by the waters in my miniature "lake" projects as
depicted here:-

(That's a large *pond* in an isolated location... hence I gave it a
pet name of "Lake Europa"!)

Thanks

Yes.
Torque, RPM, budget?

Try aquarium supply companies.

Hi,

Why does it have to be a DC motor? The pump motors you can get at garden
centers would be AC.

Looking at your site, how about a marine sump pump? Might fit the bill, is
cheap, avalible all over the place, and could be hidden below the surface of
the water.

Hi Ian,

The motor needs to be something very basic, small and 'toy-like'
actually. It just needs to run off 4 x AA batteries or a 9 volt PP3.
I just want it to keep the water surface stirring enough to stop the
pond from freezing over completely, and endangering the fish.

The motors of this type sold in Maplin (UK) are not water-proof, and
when the stirring platform takes a dive into the water during a rain
storm, the motor just ceases up and rusts. Budget... a couple of
pounds!

Thanks
Abdul

DC motor with magnet on shaft sealed inside a plastic container, outside of
the container have another magnet fixed to an impellor.

Motor turns....... impellor follows.

Just an idea!.

You can get a plastic box rated IP66 or better from Farnell for a pound
or three. Put your motor in it and make your float such that the motor
is 150 mm above the water. The motor spindle can be 150 mm long with
little problem, especially if you fit a simple guide, not a precision
bearing, at the watery end.

Or peanut butter jars. IP67 and cheaper ;)

Actually, glass is a better enclosure material than peanut butter.
Greater useful temperature range.

You should cover the lids with peanut butter. The AA institute has a
rather limited budget, so we need to be a bit creative.

Perhaps some of them might be DC, but AC vs DC is a good question; it
is the size and functionality that seems to be paramount..

There are a few motors actually designed this way...
