Abstract: A linear actuator assembly having: an actuator frame; an armature located within the actuator frame; magnets comprising: a magnetic material that generates a magnetic field, the magnetic material comprising a magnetic material thickness, and magnetic backing connected to the magnetic material comprising a magnetic backing thickness, wherein the magnets comprise: one or more first magnets connected to the first side of the armature, and one or more second magnets connected to the second side of the armature; a linear motor located on the armature and spaced apart from the first magnets by a first air gap; and a second linear motor located on the armature and spaced apart from the second magnets by a second air gap; and wherein the magnetic backing thickness is less than the magnetic material thickness; and wherein the armature, the first magnets, and the second magnets are moved relative to the actuator frame.
