ABSTRACT:
A position control method by motor drive including of rotating a rotor of the motor drive according to the given target opening, and detecting the opening of a movable vane by an encoder, the motor drive opening and shutting a passage of an intake air pipe to a turbo charger of the automobile by the movable vane, and controlling the movable vane in the passage of the intake air pipe so that it reaches the target opening. The rotational position of the motor drive is controlled to the stop position in the direction where the movable vane is closed and the stop position in the direction where the movable vane is opened. The motor drive is controlled so that the passage of the intake air pipe becomes the target opening by setting the stop position as an operation reference position of the motor drive, and setting between the stop positions as the driving dynamic range motor drive.
