Armature for electromagnetic actuator e.g. for internal combustion engine gas exchange valve, has armature plate made of plastics matrix filled with ferromagnetic particles

摘要

The armature has at least one electromagnet (1) comprising a guide pin (7) connected to an armature plate (8). The armature plate is made at least partially of a soft magnetic material formed from a matrix of an electrically non-conductive plastics filled with ferromagnetic particles. The particles are made of a soft magnetic material.
