ABSTRACT:
An electromagnetic actuator is disclosed having a case fabricated of a ferromagnetic material and defining a central axis, a core disposed coaxial with the central axis, and being in slideable engagement within the case. The core includes a first end portion, a second end portion, and a central portion. The actuator further includes magnetic flux developing element mounted coaxial with the central axis and a first and a second electrical current conductor coil. The first coil is mounted in a facing relationship with the first end portion of the core and the second coil is mounted in a facing relationship with the second end portion of the core. The coils are fabricated from a ferromagnetic material and are coaxial with the central axis. The coils have a cross-sectional length in a direction perpendicular to the central axis and a width of insulating space between the turns of the coil in a direction parallel to the central axis. The length and width are selected such that the reluctance of the width of the insulating space is greater than the reluctance of the cross-sectional length of the coil wire adjacent the insulating space.
