Maximizing the conversion of the magnetic energy created by the armature component into print energy results in higher efficiency, tighter packaging and better heat dissipation. Fig. 1 shows the armature 11, with an effective mass of M2, in contact but not connected to the impact mass, M1 . A flexible stem 12, which is physically attached to the armature 11 between M1 and M2, has a spring rate k. The magnetic force applied to the armature 11, reflected to the tip of the stem, is Fo .
