Method of producing an electrostatic motor
An example electrostatic machine includes a rotor plate and an adjacent stator plate, where the rotor plate or the stator plate includes a coupled bearing. The other one of the rotor plate or the adjacent stator plate includes a race radially aligned with the coupled bearing. The coupled bearing has a width with a first contact point on the first one of the rotor plate or stator plate and a second contact point on the race on the other one of the rotor plate or stator plate, where the coupled bearing is sized to maintain a minimum separation distance between the rotor plate and the stator plate.
