An electrostatic motor has a disc-shaped stator and a disc-shaped rotor are opposed to each other in a vacuum container. In the stator, first electrodes and second electrodes, which are attached to electrode supports, and which are electrically insulated from each other by an insulator, are arranged alternately in the circumferential direction. In the rotor, first electrodes and second electrodes, which are attached to electrode supports, and which are electrically insulated from each other by an insulator, are arranged alternately in the circumferential direction. The first electrodes and the second electrodes on the side of the stator are arranged at a spacing of two or more rows at a predetermined distance from the center of a rotating shaft. The first electrodes and the second electrodes on the side of the rotor are arranged at a predetermined distance from the center of the rotating shaft and at an intermediate position between the rows of the first electrodes and the second electrodes on the side of the stator. As a result, the electrostatic motor can establish a high electric field in the vacuum so that it can rotationally drive with a sufficient driving force. |
