Beschreibung
Zusammenfassung:	A positioning device contains an actuator composed of a DC motor, a deceleration mechanism, and a single-phase rotation sensor for detecting the amount of rotational displacement of the deceleration mechanism, and an electronic control unit that electrically drives the DC motor. The electronic control unit learns the time required for the motor to stop after turning off the power, and decelerates and controls the DC motor to stop at a target rotation stop position, which is approximately midway between the rising edge and the falling edge of the output pulse of the rotation sensor.
