Abstract (en)

[origin: WO2017009021A1] The invention relates to a method for ascertaining a position of an armature (103) of an electromagnetic actuator (101), said armature being movable by actuating a coil (102) of the electromagnetic actuator (101). The position (x) of the armature (103) is ascertained while taking into consideration a frequency of an oscillating signal in an oscillating electric system, and the coil (102) is used as a frequency-influencing element of the oscillating electric system. The invention also relates to a circuit assembly for ascertaining a position of an armature (103) of an electromagnetic actuator (101).
