'Speed 300' - that's a motor that will take 5-6A on 3-6v.

If you post up the sort of fan diameter and power you want to use, I
can tell you what would work.


Actually, I'm after a slow speed (30rpm) windmill affair, with LEDs at
the 'wingtips'
I've bought some POT's and LED's a few strip circuit boards, just hope
the simple motors can
withstand the torque as the whole arrangement also needs to rotate
around the base axis.
so the path of the LED's create an imaginary ball - approx size = 20 to
30cm
(if you see what I mean)

The natural speed of a small electric motor -is 5000-30,000RPM, so you
are going to need something like a worm drive box.
