Method for measuring an armature position and coupling device using said method

The invention relates to a method for measuring the armature position of a solenoid having a coil with a movable armature, constructed as a bistable linear magnet and activated in a switched mode by means of pulse width modulation, wherein the depth of the current peaks at the solenoid is measured a...

Beschreibung
Zusammenfassung:	The invention relates to a method for measuring the armature position of a solenoid having a coil with a movable armature, constructed as a bistable linear magnet and activated in a switched mode by means of pulse width modulation, wherein the depth of the current peaks at the solenoid is measured as a measure of the inductance and the position of the movable armature.
