Resin-cast stator based on 200W design by Hugh Piggott.

This last Sunday we cracked open the mold for our new stator based on a 200W design by Hugh Piggott, and this is what we found.  The eight coils seen inside were cast in resin and fiberglass the week before (the colors are from crayon we used to coat the inside of the mold). While we hope to generate only 10% of what this stator was designed for, we decided that building a small alternator on an existing design would not only prove to be educational from a fabrication standpoint, but would also give us a well-understood baseline from which to proceed.  At some point I hope to slap this baby on the bottom of our turbine just to see what it will do.  After all, a direct drive alternator would be superior to a smaller, chain driven alternator for a whole host of reasons…
