Abstract:
Disclosed is a micro electrostatic motor that includes a body having a first and a second face and having a chamber. A first membrane is disposed over the first face of the body and a rotatable disk is disposed in the circular chamber about a member. The disk is disposed in the circular chamber and is free to rotate about the member. The disk has on a first surface thereof a set of three mutually electrically isolated electrodes, with each of the electrodes having a tab portion and being electrically isolated from the member. A second membrane is disposed over the second face of the body and a pair of spaced electrodes are provided on portions of the second membrane, with the pair of spaced electrodes being isolated by a gap between the pair of electrodes. A cylindrical shaped member is disposed in the chamber electrically isolated from the three mutually electrically isolated electrodes on the disc.
