I read somewhere that the motor used in a floppy drive has great potential for wind to electricity conversion. Anybody has more info on this.

dont know...I read somewhere that the motor used in a floppy drive has great potential for wind to electricity conversion. Anybody has more info on this.
i plan on making a smaller version of this..It seems were getting a good 100 watts around 10mph, which is quite reasonable for a 10' prop. We probably see about 500 watts or so at 25 mph and maybe 700 at 30 when it starts furling out of the wind. 500 watts in 25 mph is a bit less than we'd hope for from the 10' prop, and I believe it's because the alternator is a bit too powerful for it.

.. due to the size and shape of the ones on that site , if you stacked three in a line , with the same polarity facing up that would work..bryan1 said:Eh WilliB,
I'm looking for some magnets aswell and I wonder if 15mm dia x 20mm thick would be suitable as www.oatleye.com have them under the general items page. These magnets are "Very strong NEODYMIUM IRON BORON RARE EARTH MAGNETS" quote from the webpage.
anyway I'll keep looking over here in Oz for them and if I find any I'll let ya know straight away.
Cheers Bryan1
really? what shape are they?FoxyRick said:Hi williB,
Not sure about one *that* old, I took a 5.25 inch HD apart once, had a very nice stepper motor (400 steps/rev iirc) for the head positioning instead of the magnets.
All the 3.5 inch HD's I've disassembled (about 10) have the magents, from old 120MB to new (dead) 40GB.

when i was a kid we had a bunch of really strong magnets around the house , i thought they were from TV's .. maybe not..Nigel Goodwin said:williB said:I'm having a hard time finding a source of magnets..

Only seriously OLD!! TV's had any magnets in them, only in B/W sets, and probably 1950's vintage.
They also weren't that strong!.
Magnetrons in microwaves have two strong magnets inside, but they are circular (as were the old TV magnets) - would they be any good?.
