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.

Electric motor and method for the operation of an electric motor

A motor and a method for serves finding the position of an armature in relation to a stator of the motor. In the method and the motor the armature is driven by an exciting field which is produced by exciting windings of the stator, and the armature is caused by the exciting field to perform an oscillatory motion, whose progression is detected by a position measuring means for measuring positions of the armature and is evaluated to determine the relative position, with the steps of:
