the thinner the windings the more heat they produce??....Is this because they have less mass ,than heavier windings....(less free electrons to flow) ............using more mass of the thin because there is less of it? Is two in hand of #7..the same as one #14.The reason I ask is because I mentioned previously about a solid stator core ...eddy brake I was told....well then look towards micro-scopic wire size.......heat is energy...........every answer I read fuels ten more questions........I'll just keep pickin.....artv
The heat depends on the power dissipated in the winding not on the size of wire.
If you make a 12v stator and a 120v one the 120v one will have much thinner wire but the two stators will do the same job at their appropriate voltages and the heat will be identical. if you try to push the current of the 12v one by running the 120v one at lower voltage then it will fry.
Heat depends on the current and the resistance, if you do things right the current will be lower with thin wire but the resistance will be higher. You can only get a certain size wire in for each voltage so the issue is not a real one.
If you ignore the eddy problem of a solid disc you would have a one turn winding and it would probably suit a 100mV battery, these are not too common so the whole process is flawed.
