    Abstract: The Objective of the present invention is to provide a multi-drive motor, which can easily fabricate responding to the design and reduce the backlash caused by meshing gears connecting to the rotation axis, comparing to the conventional motor. The objective is solved by providing a the multi-drive motor comprises: a rotor 101 having an internal gear, a plurality of element motors 11˜14 for rotating a driving gear 102 meshing from the inside with the internal gear and thereby rotating the rotor 101, and a fixing flange 103, to which the rotor 101 is fixed rotatably and the element motors 11˜14 are fixed. The bearing 104 is sandwiched between the fixing flange 103 and the opposite outer ring flange 105, further sandwiched between rotor 101 and the inner ring flange 106, and thereby the rotor 101 is fixed on the fixing flange 103 rotatably. The outer ring flange 105 is fixed on the fixing flange with screws 107, and the inner flange 106 is fixed on the rotor 101 with screw 108.
