Abstract
An electromagnetic actuator of the type having an armature positioned for movement in a magnetic gap is characterized by the armature being sufficiently compliant so as to allow the armature to contact the sides of the gap, and easily conform to the shape of the gap. The magnetic gap is substantially coextensive with the armature, for providing mechanical support to the armature. In one embodiment of the invention, the compliant armature is employed in a reciprocating actuator for a photographic shutter/aperture. In another embodiment, the invention is employed in a rotary DC motor of the pancake type. In a still further embodiment, the invention is employed in a rotary DC motor of the cup or basket type.
