Abstract: An electromagnetic actuator includes a plunger, an armature, and a coil. The plunger is moveable between a first position and a second position. The armature includes a first armature portion proximally disposed about the first position, and a second armature portion proximally disposed about the second position. The coil is proximally disposed with the first armature portion and, when energized, is configured to generate a magnetic field. The magnetic field causes the plunger to move toward the first position by a magnetic flux through a magnetic circuit. The magnetic circuit includes the first armature portion, the plunger, a main air gap, and a variable air gap. The main air gap and variable air gap are between the first armature portion and the plunger. The main air gap diminishes as the plunger moves toward the first position. The variable air gap enlarges as the plunger moves toward the first position.

Abstract: An electronic filter assembly includes a magnetically conductive annular body extending around a center axis, a set of magnetically conductive prongs radially extending from the center axis toward the annular body, and conductive windings extending around the prongs. The conductive windings can be disposed around the prongs instead of the annular body to assist in conduction of common mode magnetic flux, to reduce impedance of the filter assembly, and/or to more evenly distribute temperature in the filter assembly. A method for forming an electronic filter assembly includes forming an electronic filter assembly having a magnetically conductive annular body extending around a center axis and a set of magnetically conductive prongs radially extending from the center axis toward the annular body. The annular body and the prongs can be formed by coupling plural layers of magnetically conductive bodies together.
