Mostly Permanent Magnet Motor with minimal Input Power

These rotating contacts are at 180 degrees and one on each side of the wheel, thus, when the brushes touch these contacts, the circuit will close. The polarity of the current is reversed in the coil for each half turn. We can wire the oscillator and the SPDT switches to two batteries and the coil in series and substitute it for the "H" bridge:

This circuit is basically identical to Gotoluc's with the latching controlled by the commutator shape.

Newman's commutator is designed to pulse the coil when the north south rotor magnet is at an angle to the coil axis to propel it from the lenz reversal at TDC. The rotor will attract to the opposite coil poles at 45 degrees and repel from field reversal at 90.

The oscillator self times it's own kickback, and has no need for a Newman commutator.

The piezo transducers are at the end of the power stroke only: This is an overunity design.

This 10 pound skein of 22 gauge magnet wire would carry nearly 5 Henries of inductance. This would deliver around 1 meter of Adam's resonance throw. Joe Newman ties 9 volt batteries together in series to reach voltages sufficient to overcome the large resistance.
