Abstract
An electric motor having a rotor and a stator as well as a measuring device designed for detecting a position of the rotor, which is movable relative to the stator, and comprising a sensor system for the provision of sensor signals in dependence on the position of the rotor relative to the stator and a processing device for controlling the sensor system, for processing the sensor signals and for outputting a position signal. The processing device is configured for switching between a first operating state with a continuous or high-frequency intermittent provision of supply energy to the sensor system and a second operating state with a low-frequency intermittent provision of supply energy to the sensor system.
