Hi All,
How hot does a stator get? Can it be water cooled?
My idea is to cast some channels in/around the coils and pump cold water through the stator, would this work, and if so wouldn't it improve the efficiency of the generator. I'm not sure exactly how I would make the 'water course' through the stator but I'll figure something out if it would produce a reasonable hike in efficiency.
I guess I'm looking for some brain boxes to tell me the sums and formula I should be looking at, lol Ideas I have! Knowledge I'm lacking!
Let's assume it's a 12 mag 9 coil pma, with twin rotors 1 either side of the stator (the standard home build axial flux genny).
Incidentally just out of my own curiosity and because I'm often accused of being completely mad, what would be the best way to create a stator that would burn up in any strong wind, ie. if I used really thin winding wire, would that do it.
Hope this provokes some thought, I've seen water cooling on industrial stators but not seen it done with the home build type.
