ABSTRACT:
A linear electromagnetic machine has a stator with a coil mounted thereon. A reciprocating element has permanent magnet segments of alternating polarity so that reciprocation of said element relative to said stator in an axial direction causes periodic flux reversal through the coil to induce an alternating voltage therein. The magnetized segments are of equal axial extent and are axially spaced by transitional regions that are of axial extent substantially less than that of the magnetized segments. Flux return and core elements associated with the stator provides a relatively low reluctance magnetic path for flux lines resulting from magnetization of the permanent magnets wherein the reluctance is generally independent of the position of the reciprocating element.
