Abstract: The disclosure relates to the detection of a rotor position (?EM) of an electric motor which comprises at least one stator, at least one rotor that can be rotated relative to the stator, thereby changing the rotor position (?EM), and at least two motor phases. The rotor position (?EM) is detected on the basis of a rotor position reference value (?b) which is calculated from electric operating variables of the at least two motor phases, wherein the electric operating variables are applied to a reference system which is fixed to the stator in order to calculate the rotor position reference value (?b). The disclosure additionally relates to an analysis device and a drive device.

Abstract: A method is provided for ascertaining a rotary position of a rotor, which is assigned to an electric motor and which is able to rotate about an axis of rotation with respect to a stator and the rotary position of which is ascertained by at least one measurement value of a rotary sensor by virtue of at least one measurement value of the rotary sensor being compared at a first time during operation of the rotor with a stored sensor measurement value reference. The method includes calculating the rotary position present at the rotor at the first time based on a comparison between a sequence of measurement values and a sequence of reference values. The stored sensor measurement value reference includes the sequence of reference values, and the reference values are previously stored measurement values of the rotary sensor at various rotary positions of the rotary sensor. The measurement values recorded before the first time are stored as the sequence of measurement values.
