Abstract (en)
[origin: EP0408963A2] In a method for controlling the armature movement of a switching magnet, in particular of electromagnets for actuators of internal-combustion engines, it is intended to reduce considerably the energy and material consumption. This is achieved in that the coil current of the electromagnet is linearly regulated before the expected impact of the magnetic armature on the pole surface. The impact of the magnetic armature on the pole surface of the electromagnet preferably occurs in this case during the linear regulation. <IMAGE>
