Print the rotor stator and bobbin files.
The bobbin will be a Bifilar Coil: Take 32AWG magnet wire (two strands) and the bobbin 144 times. Leave quite a few inches of wire of both sides of the coil. This bobbin is going to be your primary coil that moves the rotor, we will need to place a metal core into the bobbin so it can act as a magnet when electricity flow through the wire in the coil. The bedini circuit only requires one coil to operate. (The additional places for coils are for elevating the concept. all coils will be 32awg @ 144 turns, however not all need the metal core.)
With one coil and the bedini circuit this motor can easily demonstrate that a single 12 volt battery can charge multiple dead 12v batteries. Now consider the "Daftmans Circuit" that switches the Primary battery to the Charging battery automatically once the primary battery gets low...

Standard Bedini SSG Circuit should run it just fine, consider potentiometer

Can a half dead 12v battery charge multiple 12v deep cycle batteries?
