Method and assembly for determining the dynamic status of an electric motor

摘要

The method involves uniquely determining rotational positions of a rotor, an actual rotational position relative to an actual output rotational position and the output rotational position relative to a reference output rotational position. The determination of the output rotational position is taken place exclusive from an output signal of a position indicator (7). The output rotational position is determined by comparison of courses of portions of systematically varying signal interferences of measured values of a current signal sequence and an obtained signal sequence of the output signal. An independent claim is also included for an arrangement for detecting a dynamic state of an electric motor.
