An electrostatic motor comprising: a vacuum container or a container containing insulation gas, the container having a main body; a disc-shaped stator which is fixed to the main body in the container; and a disc-shaped rotor which is disposed opposite to the stator in the container, and which is pivotally supported so as to freely rotate via a rotating shaft, wherein: the stator has first electrodes attached to a first electrode support and second electrodes attached to a second electrode support, the first electrode support and the second electrode support are insulatively supported by a first insulator to provide a creepage distance between the first and second electrode supports, the rotor has third electrodes attached to a third electrode support and fourth electrodes attached to a fourth electrode support, the third electrode support and the fourth electrode support are insulatively supported by a second insulator to provide a creepage distance between the third and fourth electrode supports, the first electrodes, the second electrodes, the third electrodes and the fourth electrodes respectively extend along an axial direction of the rotating shaft, the first electrodes and the second electrodes are spaced apart from a center of the rotating shaft at a predetermined distance, and respectively form at least two rows, wherein the first electrodes and the second electrodes alternate along the circumferences of the first and second electrode supports, the third electrodes and the fourth electrodes alternate along the circumferences of the third and fourth electrode supports, and are arranged in a row at a predetermined distance from the center of the rotating shaft so as to be intermediate between the rows of the first electrodes and the second electrodes, and the electrostatic motor is configured to apply predetermined electric fields between the first electrodes and the second electrodes, and to apply voltages of different polarities to the third electrodes and the fourth electrodes so as to be switched at a predetermined timing. a vacuum container or a container containing insulation gas, the container having a main body; a disc-shaped stator which is fixed to the main body in the container; and a disc-shaped rotor which is disposed opposite to the stator in the container, and which is pivotally supported so as to freely rotate via a rotating shaft, the stator has first electrodes attached to a first electrode support and second electrodes attached to a second electrode support, the first electrode support and the second electrode support are insulatively supported by a first insulator to provide a creepage distance between the first and second electrode supports, the rotor has third electrodes attached to a third electrode support and fourth electrodes attached to a fourth electrode support, the third electrode support and the fourth electrode support are insulatively supported by a second insulator to provide a creepage distance between the third and fourth electrode supports, the first electrodes, the second electrodes, the third electrodes and the fourth electrodes respectively extend along an axial direction of the rotating shaft, the first electrodes and the second electrodes are spaced apart from a center of the rotating shaft at a predetermined distance, and respectively form at least two rows, wherein the first electrodes and the second electrodes alternate along the circumferences of the first and second electrode supports, the third electrodes and the fourth electrodes alternate along the circumferences of the third and fourth electrode supports, and are arranged in a row at a predetermined distance from the center of the rotating shaft so as to be intermediate between the rows of the first electrodes and the second electrodes, and the electrostatic motor is configured to apply predetermined electric fields between the first electrodes and the second electrodes, and to apply voltages of different polarities to the third electrodes and the fourth electrodes so as to be switched at a predetermined timing.
