Thanks for the info. and photos. I will consider using a pickup coil next to the flywheel on my motor. Does the polarity of the magnet determine the direction of the current?
Nice to see a workbench as tidy as mine!

Peter,
I guess I'm not fully understanding the question. The polarity of the pickup coil, driving coil, or back emf?

The polarity of the driving coil must change to match the polarity of the rotor magnets if the magnets are N-S-N-S.

Peter,
The coil only fires twice per revolution. The diode on the pickup coil only lets current flow one way through the transistor, which allows the current to flow through the driving coil. Either attraction or repulsion will work, however I find repulsion to work better. While the coil is pushing the north magnet away, its is attracting the south magnet. I find that a bifilar coil (single coil wrapped with two wires) works well with this design. Also, since I don't use ferromagnetic cores, I don't have to fasten my coils if I'm using small amounts of wattage (like less the 1/2 watt). This allows me to move the coil around without fear of hitting the magnets.

Okay Jason. That clears things up. The driving coil fires twice /revolution with four magnets on the rotor. The pick-up coil is positioned to determine when this firing takes place.
Yes, I did wind a bifilar coil for my first pulse motor. Since then, Ian Coke-Richards http://www.mintakafulcrum.net/ has been winding them for me.
