A 2−shaft motor that is compact and whose output shaft is capable of performing spherical action, wherein the stators (9, 19) and movable elements (10, 20) of two linear motors (8, 18) of different sizes are bent arcuately around a common arc center (O) to allow the movable elements (10, 20) of the two linear motors (8, 18) to perform rotational motion, the movable elements (10, 20) being disposed orthogonal to each other, the movable element (20) disposed inside being provided with an output shaft (30).
