The present invention relates to a coreless magnet gear type three-phase AC motor capable of improving the output and efficiency of a motor by rotating an internal rotor and an external rotor in the same direction at the same time. The present invention includes an internal rotor shield inserted into the outside of a rotation shaft; an internal rotor which comprises a rotation magnet installed to the center edge part of a rotor shield; a first bobbin of a recess shape which is inserted into the outer edge of the internal rotor; a second bobbin of a recess shape which is inserted in to another side of the first bobbin; a coil (U1)(U2), (V1)(V2), (W1)(W2) for a three-phase AC motor wound around the insertion part of the bobbin; an external rotor which comprises a rotation magnet arranged on the outside of the internal rotor; and an external rotor shield which is installed to the edge of the external rotor. |
