摘要：
An actuator includes an iron member having a shape selected to define a first opening in a central portion thereof and a plurality of armature openings in a periphery thereof and having a gap extending from the first opening to the plurality of armature openings, a plurality of permanent magnets with each of the plurality of permanent magnets disposed in a respective one of the plurality of armature openings and an armature formed by an array of current conductors. The armature includes a winding and has shaft is disposed through the first opening in the central portion of the iron such that at least a portion of the winding is disposed in each of the plurality of armature openings such that the windings are movable within the armature openings of the iron.
