摘要： A magnetic actuator comprising a stationary magnetic core structure having two distinct magnetic flux paths, with a movable armature included in both the flux paths and movable between a rest position and an actuated position. A permanent magnet or winding provides reset or restore flux, and a first winding includes the armature and opposes the restore flux. A second winding provides the major armature attractive force.

摘要： An electromagnetic print hammer comprises a magnetic core structure having a magnetic core with an armature movable between one flux path and another flux path. Means are provided for producing a magnetic flux in said core structure and control windings are energized to switch the flux from said one to said another flux path causing the armature to change position.
