Abstract

An apparatus for electromagnetic actuation includes a cylindrical housing (6). The apparatus further includes at least two stationary cores (1A, 1B) fixed to the cylindrical housing (6). Each stationary core (1A, 1B) includes at least one first annular portion having a first annular thickness between a first inner diameter and a first outer diameter. The apparatus further includes a ring coil fixed to and in operable communication with each of the at least two stationary cores. The apparatus further includes a ferromagnetic armature (3) concentrically aligned with the at least two stationary cores and configured to move relative to the at least two stationary cores (1A, 1B). The ferromagnetic armature (3) has at least one second annular portion having a second annular thickness between a second inner diameter and a second outer diameter. The second annular thickness is about the same as the first annular thickness.
