Abstract: 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.

Abstract: An example electrostatic machine includes a number of stator plates, each having a stator electrode and rotationally fixed to a housing, a shaft at least partially defined within the housing and configured to rotate about an axis, and a number of rotor plates, each having a rotor electrode and rotational fixed to the shaft. The electrostatic machine includes a dielectric fluid disposed in the housing, and that fills a gap between the stator plates and the rotor plates. The electrostatic machine includes a seal associated with the shaft, where the seal includes a material compatible with the dielectric fluid.
