  • Determining the movement profile of an armature in a magnet
    Patent number: 10796832
    Abstract: A method and a device determine a movement profile of a solenoid plunger in a solenoid for monitoring a plunger-type armature movement for changes. The solenoid is an electromagnet in which a magnetic field can be generated by an electrical coil and a measuring unit is connected to the electrical coil. The method includes measuring a current profile with respect to time when the solenoid is operated, examining a measured current profile with respect to time for a position of a first reversal point in respect of time after operation of the solenoid and a current intensity, and assigning the position of the first reversal point to a movement end of the plunger-type armature.
