23a and 23b are the output coils for the recovery. You may want to check out the full patent at http://www.google.com/patents?id=wSkJAAAAEBAJ&dq=6,392,370

Ren,
I replaced the diode in the circuit and let it charge up a 9 volt battery. It seems that it charges just as fast as without it. It cuts the motor input by almost half. From 5volts @ 25 milliamp to 5volts @ 15 milliamp. So, I am going to continue to use the circuit with the diode in place. The only thing the diode doesn't allow me to do is run the motor at 3 volts or less.

Chadj2,
I use only air coils with my motors. This is because I use very large neo's, and working with iron around them is damn near impossible to change setups easily.

Thanks Jason. I checked it out and it looks like he wraps 23a over top 22a and 23b over top 22b. If that's the case, you should be able to wrap 2 wires around the same core and use one to pulse and one to capture BEMF.

Tropes,
Yes, you could wrap a trifilar coil and use my exact setup and use the third wire to capture the back emf. Or you could wrap a three layered coil. It would be a good experiment to try both setups. I may have to try this.
