Abstract
An example system including an electrostatic machine including a rotor plate comprising a plurality of rotor electrodes, and rotatably fixed to a shaft configured to rotate about an axis; a stator plate comprising a plurality of stator electrodes, and rotatably fixed to a housing defining the rotor plate, the stator plate, and at least a portion of the shaft; an excitation circuit electrically; a controller, comprising: a rotor feedback circuit structured to interpret a voltage response value; a rotor position characterizing circuit structured to determine a voltage injection value; and a rotor position circuit structured to determine a calibrated rotor position value in response to the rotor position value; and wherein the excitation circuit is responsive to the voltage injection value to inject a voltage on at least one of the plurality of rotor electrodes or stator electrodes.
