Abstract (en)
[origin: US4527139A] A high-speed reciprocating actuator, of the type used as a print hammer in high-speed printers or for operating valves or the like, is made more compact and efficient by the arrangement of a stator yoke. The stator yoke provides a series of aligned magnetic gaps that cooperate with armature bars contained in a reciprocating ram member. These gaps are made part of a plurality of independent flux conducting loops. One or more activating coils pass through each of the loops to induce magnetic flux when ram actuation is desired.
