Method and device for adjusting an actuator member of a positioning system with an electronically commutated actuator drive

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 φel 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 that
• the 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 θO,
• setting the amplitude A to an operating amplitude AO,
• wherein the operating differential phasing θO and the operating amplitude AO are set such that the operating differential phasing θO 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.
