Abstract

A method of determining an angle of rotation and/or a rotational speed of a motor shaft (110) of a motor (105) which is designed to produce a translational movement of a control element (115, 115a) relative to the motor (105). The method includes a step of reading in a movement signal via an interface with at least one sensor element (120) arranged outside the motor (105) such that the movement signal represents a translational movement of the control element (115) relative to the motor. In addition, the method further includes a step in which, using the movement signal, the angle of rotation and/or the rotational speed of the motor shaft (110) is/are determined.
