MOVEMENT DEVICE HAVING LINEAR MOTOR

摘要

A movement device includes: a linear motor including a mover and a stator and moving a movement body including the mover in one axial direction; a rotational motor having a rotor and included in the movement body; and a control device. The rotation axis of the rotor passes through the center of gravity of the movement body and intersects a plane including the center of gravity and the path of movement of the mover. The control device controls the rotation of the rotor so that the counter rotational torque which compensates at least a part of rotational torque acting on the movement body due to the movement of the mover is generated in the rotor.
