The present invention relates to an armature unit and a rotator having the same. The rotator comprises a shaft; annular shape armature yokes in which a hollow part is arranged in the internal center so that the shaft can be inserted; armature units which are arranged to be adjacent to each other along the circumferential direction of the armature yokes and include a plurality of coils installed in the armature yokes to occupy the upper surface and a portion of the bottom surface of the armature yokes; a housing which is formed to cover the external side of the armature units and is installed in the shaft to allow the rotation movement relative to the shaft; and field magnet units having annular shape field magnet yokes which are installed in the inside of the housing to be arranged in at least either of the upper side or the lower side of the armature units and magnetic force generation parts which are arranged to be adjacent to the field magnet yokes along the circumferential direction of the field magnet yokes and supply the magnetic force toward the armature units. The armature unit according to the present invention may improve the space factor of the coil, thereby improving the power generation efficiency of the power generator in the use as the power generator. |
