Patent ID: 6930414

Claim:
A linear electrodynamic system comprising: a housing; a longitudinal shaft movably coupled to the housing to longitudinally and linearly reciprocate relative to the housing in the longitudinal direction of the shaft; a stator rigidly coupled to the housing, the stator shaped to define an inner space to receive a portion of the longitudinal shaft, the stator having stator poles extending inwardly toward that portion of the longitudinal shaft received by the stator; windings wound around the stator poles; magnetic material affixed to a portion of each of the stator poles, the magnetic material having bore surfaces facing inward; and a mover affixed to the shaft, the mover having bore surfaces facing outward in correspondence with the bore surfaces of the magnetic material to define a gaseous gap between each of the correspondingly positioned ones of the bore surfaces of the magnetic material and the mover, portions of the bore surfaces of the magnetic material being closer to the shaft than portions of the bore surfaces of the mover, the bore surface of each magnetic material affixed to a portion of one of the stator poles having a V shape, the bore surface of each magnetic material affixed to a portion of one of the stator poles having a concave shape.
