ーターアクチュエータ。A unidirectional rotating AC motor, a first switch means and a second switch means operated by the AC motor, and a drive command for the motor based on an external signal for driving the motor and a signal from the second switch means. A signal generating means for generating a signal, and a control means for receiving the drive command signal and driving the ΔC motor, the first switch means forming a part of the control means, and when the drive command signal is not present. Sixth, the control means is operated to drive the AC motor, and after the 8C motor has rotated by a predetermined amount, the control means is turned off;
The second switch means is configured to generate the same signal even if the AC motor rotates slightly in the opposite direction, and is configured to ensure that the upper AC motor rotates to a predetermined position when the drive command signal is generated. A motor actuator characterized by:
