Electrostatic micro-motor apparatus.

摘要

An electrostatic micro-motor apparatus (K) capable of transmitting driving force of an electrostatic micro-motor, comprises a rotor (12) which has the shape of a gear substantially. A plurality of electrodes (13a-13r) confront teeth of the rotor and are disposed at a predetermined circumferential region around the rotor (12) so that a circumferential gap(s) (G1, G2) is defined around the rotor (12). A transmission gear or gears (14, 15) is/are provided in the circumferential gap(s) (G1, G2) so as to be in engagement with the rotor (12).
