Motor control device and seat control device for vehicle

A motor control device (10) includes an acceleration portion (2) for increasing a target number of rotations (VT) of a motor (30) every predetermined calculation cycle until the target number of rotations (VT) of the motor (30) reaches an upper limit number of rotations (VL), which is set on the basis of a reached position of a driven object from a reference position, the driven object is driven by the motor (30) so that a position of the driven object is changed, a deceleration portion (4) for decreasing the target number of rotations (VT) of the motor (30) every calculation cycle after the target number of rotations (VT) reaches the upper limit number of rotations (VL), and a main control portion (1) for controlling a drive of the motor (30) on the basis of the target number of rotations (VT).
