Making a stator

Stator is center part of a PMA (Permanent Magnet Alternator). It is in the stator that a current is formed. The stator consist of a number of copper coils resin casted into a circle. The number of coils in a stator depends on the number of magnets on a rotor. To make a 3phase alternator the number of magnets divided by the number of coils has to equal 1 and 1/3-ds.
The easiest way ro make coils is by using a coil winder. It consists of 4 main parts and is easily manufactureable at home. The copper wire that is used to wind coils is chosen upon the voltage requirement for the system. The copper wire can be bought at different thickensses, measured commonly as #XX (x-means numbers)gage. A wires cross section roughly halves everytime the wire size goes up 3 times. The voltage of the turbine directly relates to the number of turns in a coil. If you double the turns in a coil you double the current. If your planning to make a 12V system you should know that for that you need the thickest wire, it is resolved with using two strands of wire and connecting them as one.
