thats nice !..
it must have a feromagnetic core inside each armature..

It looks like a DC brushless motor?, in particular, a drum motor out of a VCR.

has achieved up to 600 watts with a wind or hydro drive.

The motor supplied consists of a copper wire wound 42 coil 3 phase stator with a Hall Effect controller and a permanent magnet rotor

rotor is the grey bit

At 12volts DC it should produce 50-100 amps depending on the rpm. Diodes are needed for rectification to DC.

I have been thinking about the savonius again lately..
let me run this by you..
say you live in a building where you dont really have a lawn on which to install your wind generator .. i live upstairs in a two story condo.anyway, i think the savonius would be perfect, because it is designed to spin horizontally to the ground ..what if you attach it to the side of your building as in the picture..or out your window.. this way whichever way the wind is going past your generator it will turn..
Barring any building codes or any bs like that ,this is just hypothetical..
i made an anemometer last night with an attached wind direction indicator the wind is generally from the north at the moment but sometimes it comes from the ground, like the arrows indicate ..
with bearings on the top of the savonius , it just might work..

The motor that is shown above looks to me like the stepper motor off a fisher paykel washing machine. Now in the current issue of siliconchip there is an article showing how to modify this motor for use as a wind generator. I'm looking in all the salvage yards around town looking for 1 but no luck so far

Cheers Bryan1

I thought it was designed to spin vertically?, so it doesn't require steering into the wind?. Mounting it on a wall like that will severely restrict the wind direction it can pickup.

It is usually mounted vertically , and usually spins horizontally , BUT since a wall is vertical the way the wind passes by a wall , if the savoniusis mounted on the wall it will be just like it is mounted on the ground..

Only when the wind is in the right direction!, I meant mounted vertically in my previous reply - when it can receive wind from any direction.

If you mount it horizontally on a wall it can only receive wind from two directions, severely restricting it's operational range.

williB · 23rd January 2005, 07:16 PM

Whichever way the wind is blowing , up , down , right , left , it will spin..
If it is mounted like the picture..

But wind doesn't come from UP and DOWN, it comes from North, South, East or West (or anywhere in between).

With it mounted horizontally it will only collect wind from two opposing angles - the whole idea of this type of wind collector is that it collects wind from any direction - which requires it mounting vertically.

williB · 23rd January 2005, 08:15 PM

yes it does come from , up ,down when you live on the second floor, granted the strongest gusts today , are comming from the north , all i am saying is that when the wind hits the side a building it is likely to
A) travel parallel to the ground..
B) move up the building ..
C) move down the building..

I don't think it's going to collect anywhere near as much as with it mounted vertically, as designed.

williB · 23rd January 2005, 10:21 PM

You cant see it but i have a hall effect switch attached to the base , and a magnet attached to the inside of central can..
essentially it a tuna can anemometer with a cheap radio shack motor (rotor) as the main shaft , sticking out the top and the plastic " bearing " as the bearing..
total cost $ 0.0 .. LOL
