Abstract
Systems and methods for modified dimensions, configurations, and structure for rotor electrodes and stator electrodes to improve power transfer between such electrodes. Swept-forward, swept-backward, and Yin-Yang shaped electrodes can be used to shift the power response of the motor forwards or backwards in the rotation of the rotor electrode. Modifying the leading edge of the rotor electrode and/or the pitches of the rotor and/or stator electrodes relative to one another may be used to further change various characteristics of the motor, including the power transfer efficiency, the relative locations of the peak overlap between electrodes, and locations of maximum and minimum mechanical strain on the rotors. A curved power feed structure associated with the rotor electrode may be used to distribute the electric charges over a larger area and protect against arcing from the rotor electrode.
