摘要： 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.

摘要： A supersonic vibration driven motor comprising a supersonic oscillator and a mass rotationally driven thereby. The oscillator is provided with a vibration disc secured thereto on an end face thereof opposite to the mass to be driven. The mass is integrally formed with a plurality of plate-shaped resilient vibratory pieces annularly arranged on the end face opposite to the oscillator and axially extending at a predetermined angle of inclination relative to the axis of the mass, the vibration disc and vibratory pieces being located so as to come in contact with each other at their end portions, whereby vibratory displacement of the supersonic oscillator is transformed into rotational movement of the mass by way of flexible deformation of the vibratory pieces. Alternatively, the resilient vibratory pieces may be formed integrally with the vibration disc. A plurality of supersonic oscillators may be annularly arranged and located so as to come in contact with the end face of the mass so that operational phases of the respective supersonic oscillators have a predetermined phase relationship ensuring even and smooth rotation. A plurality of supersonic oscillators integrally formed with vibratory pieces and arranged in linear alignment may be located so as to come in contact with a mass to be linearly driven, whereby vibratory displacement of the supersonic oscillators is transformed into linear movement of the mass by way of flexible deformation of the vibratory pieces.
