Abstract

A method is proposed for adjusting an actuator (300) of a positioning system (100). The positioning system (100) has an electronically commutated actuator drive (200) which is coupled to the actuator (300), wherein the actuator drive (200) has a permanent magnetic rotor (210), wherein the rotor (210) has a first shaft (212) which extends along a pole axis (290) of the rotor (210). The actuator drive (200) additionally has an electronically commutated stator (230), wherein the stator (230) can be energized using a space phasor (260), wherein the space phasor (260) has an electric phase and an amplitude, wherein the space phasor (260) is aligned with respect to the first shaft (212) of the rotor (210) around a difference phasing. In order to be able to actuate a predefined position of the actuator, even without sensors to determine the position of the first shaft (212) of the rotor (210), the following steps of the method are thereby provided: setting the difference phasing of the space phasor (260) to an operating difference phasing; setting the amplitude to an operating amplitude, wherein the operating difference phasing and the operating amplitude are set in such a way that the op…
