Hi tecker,
Thanks for the pictures of your fan conversion. This flat bar ring seems a good way to go. Did you just try to reproduce the slant in the original cage with your magnet placement? That seems a good way to glue magnets on. If I can get larger magnets, I would like to be able to stick in place directly in the case. But I understand the flat bar also acts to redirect the magnetic flux. Is that the intent?
As of the coil connections, here is how I view it. Please tell me if you think I am right.
Original (induction motor):
two set of nine series-connected coils . One end of each set is connected with the other set to the white wire. The other end of one set to the black and that of the other set to the capacitor and to the black. The black and the white to the grid.
Modified (PMA):
Two sets of nine parallel-connected coils. Each set will have two wires. A total of four wires will have to be rectified separately.
