ABSTRACT:
An electrostatic micromachine motor includes a rotor having a hub and one or more rotor poles extending radially outward from the center of the hub. Near an exposed end of each rotor pole, an electron trap region is formed between a first layer and a second layer, with the first layer being the exposed end of the pole. The first layer and the second layer are formed of dissimilar insulators. An emitter device may be positioned adjacent to the exposed end of each rotor pole for injecting electrons into the electron trap region. Preferably, the emitter device is positioned adjacent to the exposed end, such that the emitter has a tip pointing towards, and spaced at a distance less than a mean free path distance of an electron in air, away from the first layer. A plurality of stator poles may be aligned about a periphery of the rotor. Both positive and negative voltages may be applied to the plurality of stator poles for causing rotation of the rotor of the micromotor.
