Patent ID: 7994661

Claim:
A linear electrodynamic system comprising: a mover member configured to reciprocate having a path of travel including a first position of travel and a second position of travel; a plurality of magnet pairs each comprising a first magnetic material coupled to the mover member and a second magnetic material coupled to the mover member, the first magnetic material positioned adjacent to the second magnetic material along the path of travel, the first magnetic material having a first surface portion of a first polarity and a second surface portion of a second polarity, the first surface portion of the first magnetic material being convex, the second magnetic material having a first surface portion of the second polarity and a second surface portion of the first polarity, the first polarity being an opposite polarity of the second polarity, the first surface portion of the second magnetic material being convex; a stator comprising a stator assembly and a stator member, the stator being coaxial with the mover member on an axis parallel to the path of travel, the stator assembly being closer to the axis than the stator member, the stator assembly being coupled to the stator member and spaced therefrom such that the stator assembly is substantially stationary relative to the stator member when the mover member reciprocates along the path of travel, the stator assembly comprising a pole support and a plurality of stator poles each having an end portion and extending outwardly from the pole support toward the mover member, the first surface portion of the first magnetic material of each of the plurality of magnet pairs being in juxtaposition with the end portion of one of the plurality of stator poles of the stator assembly and the second surface portion of the first magnetic material of each of the plurality of magnet pairs being in juxtaposition with the stator member when the mover member is at the first position of travel, the first surface portion of the second magnetic material of each of the plurality of magnet pairs being in juxtaposition with the end portion of one of the plurality of stator poles of the stator assembly and the second surface portion of the second magnetic material of each of the plurality of magnet pairs being in juxtaposition with the stator member when the mover member is at the second position of travel, wherein the stator assembly, the stator member, and the mover member are so arranged to allow for a magnetic flux loop to pass therethrough, the flux loop defining a plane, wherein the path of travel is substantially perpendicular to the plane; and for each of the plurality of stator poles, a winding wound about the stator pole and positioned between the end portion of the stator pole and the pole support.
