Half-Tesla-switch or Siamese-twins-Bedini-SSG or partly-Newman-motor. The second battery is replaced by a capacitor. The first battery has a capacitor in parallel so the battery can be disconnected (and the motor slowly stops, I hope to fix that...). The switches are two solid-state-relays controlled by a trigger-coil. The coils are two unifilar air-core coils. The diodes are in the relays. The variable-resistor is in series with the trigger-coil to trim the rise/fall-slopes of the relays. The rotor is a stack of neo's, so its not a monopole-motor, but rather a bipole-motor as I'm using both poles of the magnet-stack.
