Abstract:
1. A movement device, comprising: a linear motor including a mover and a stator, to move a movement body that includes the mover in one axis direction; a rotational motor, included in the movement body and including a rotor, wherein a rotational axis of the rotor passes through a center of gravity of the movement body, and intersects a plane including the center of gravity and a path of movement of the mover; and a control device, controlling a rotation of the rotor so as to generate a counter rotational torque that compensates at least a part of a rotational torque that acts on the movement body due to a movement of the mover, wherein the linear motor moves the mover in a horizontal axis direction or in a vertical axis direction, and the rotational axis of the rotor is perpendicular to a horizontal plane or a vertical plane.
