    摘要: The detection of a valve-opening starting position of an exhaust gas recirculation (EGR) valve which is disposed in an exhaust gas recirculation system is surely made, and the amount of movement of a motor shaft of an electric motor in a valve-closing direction is restricted. In this manner, the motor shaft is prevented from striking a stopper which restricts the operating range of the electric motor.

    摘要: When a valve lift control signal is received from a control unit 10, two coils from amongst the coils 18a-18d in a step motor 18 are excited and an aperture of a valve 14 is regulated. When the aperture regulation of the valve 14 is completed and a fixed period of time elapses, the excitation mode of the step motor 18 is switched from 2-phase to 1-phase.
