| In the last couple windmills I made I took lots of pictures but never made things very clear about exactly how they are wired up.
In response to Paulpics posting, and lots of email about how to wire up the 3phase stator where we have 12 magnets, and 9 coils I made these drawings.
Each coil is numbered - and colored, according to which phase it's in. Each coil has a "start" - which is the inside, and an "end" which is the outside. The "starts" are labeled A, B, and C, and the "ends" X, Y, and Z.
So we have the choice to wire the stator into Delta, for lower voltage and lower resistance... and higher current, or Star for the opposite. The windturbines I made recently are all wired in Delta and the picture above shows the connections. Then we can either use 6 diodes, or 2 bridge rectifiers to rectify the 3 phase alternating current into direct current which we hook to batteries for charging. In practice - I actually use 4, or 6 35 amp bridge rectifiers - hooking them into parallel to simply increase the current rating since two are not enough to handle the output of these wind turbines.
