Beschreibung
Zusammenfassung:	A linear motor or generator includes a cylinder having left, center, and right magnetic portions interposed with left and right magnetic gaps, a left and a right induction coil axially wound around a longitudinal axis of the cylinder, and a flux bridge that magnetically couples the center magnetic portion to the left and right magnetic portions. The motor or generator also includes a flux modulating piston comprising a soft magnetic material for increasing magnetic flux circulation in the left flux path when the piston overlaps with the left magnetic gap and for increasing magnetic flux circulation in the right flux path when the piston overlaps with the right magnetic gap. The left and right magnetic portions of the cylinder may be made of a soft magnetic material that promotes magnetic flux.
