IMPACT PRINTER ACTUATOR ABSTRACT A print actuator for dot matrix applications having a stator with a coil wrapped thereon and constrained by the walls of the stator. An armature extends above the stator in a cantilever or pivoted manner. The armature controls movement of a print element. The magnetic flux path extends transversely through the width of the armature and the periphery of the stator at walls supporting the armature. Multiple armatures are included in a common armature plate. Twin multi-coil stators are mounted for operation of the armatures on the plate. The stators have magnetic stator sections adjacent the armatures, and have non-magnetic heat-dissipating stator sections remote from the armatures. In its cocked position, the armature is flexed to a profile which optimizes armature dynamics, such as a profile similar to the first bending mode.
