Electrostatic motor

A method, comprising:

• interpreting, by a rotor feedback circuit of a controller, a voltage response value corresponding to at least one of a plurality of rotor electrodes or a plurality of stator electrodes included in an electrostatic machine, wherein the electrostatic machine comprises:
• a rotor plate comprising the plurality of rotor electrodes, and rotatably fixed to a shaft configured to rotate about an axis;
• a stator plate comprising the 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;
• and
• an excitation circuit electrically coupled to at least one of the rotor plate or the stator plate at a first end, and electrically coupled to an electrical power source at a second end;
• interpreting, by the rotor feedback circuit, a rotor position value corresponding to the voltage response value;
• determining, by a rotor position characterizing circuit of the controller, a voltage injection value comprising a voltage injection trajectory, wherein the voltage injection trajectory comprises a voltage progression to be injected onto the plurality of stator electrodes, and wherein the voltage response value corresponds to the plurality of rotor electrodes;
• determining, by the rotor positioning characterizing circuit of the controller, a second voltage injection value comprising a second voltage injection trajectory comprising a second voltage progression to be injected onto the plurality of rotor electrodes;
• determining, by a rotor position circuit of the controller, a calibrated rotor position value in response to the rotor position value corresponding to the voltage response value;
• and
• responsive to the voltage injection value, injecting, by the excitation circuit, a voltage on at least one of the plurality of rotor electrodes or stator electrodes.
