1. A method for adjusting an actuator member of a positioning system,wherein the positioning system has an electronically commutated actuator drive which is coupled to the actuator member,wherein the actuator drive has a rotor with permanent magnets, wherein the rotor has a first axis which extends along a pole axis of the rotor,and wherein the actuator drive has an electronically commutated stator,wherein the stator can be energized with a space phasor, wherein the space phasor has an electric phase φ

  • el and an amplitude A, wherein the space phasor is oriented about a differential phasing θ

    relative to the first axis of the rotor,characterized in thatthe method comprises the following steps for controlling a predefined position of the actuator member;

    setting the differential phasing θ

    of the space phasor to an operating differential phasing θ

    O,setting the amplitude A to an operating amplitude AO,wherein the operating differential phasing θ

    O and the operating amplitude AO are set such that the operating differential phasing θ

    O is less than 45°

    , and that a torque is generated which acts on the rotor and is suitable for approaching the predefined position of the actuator member.
