Well, today I tried to convert a fan so that it runs on a basic SSG setup, but this time I wanted to use all the recovered energy in a capacitor on primary side (like Peter showed in electric motor secrets thread) rather than in a charging battery. I used one fan pole for a trigger winding of fine wire. Second and third pole was wound with about 80 turns of AWG24 wire. The remaining pole was left unused. This way I had a trigger coil, a power coil and a recovery coil with a bridge rectifier on the output. The fan run nicely, but the neon was flashing as if the recovery coil was not attached to a charging battery. Tried many things, even a neon bulb on the recovery winding would not light up. I am convinced that this is just because of the stator core geometry. I will try to use bifilar windings tomorrow.
