Abstract
An actuator having a part that is capable of moving both longitudinally and transversely may include a housing having a longitudinal axis with respect to which the movable actuator part can move within the housing both longitudinally and transversely. The actuator may include electromagnetic windings on a central section of the moveable part and permanent ring magnets disposed thereabout within the housing. The housing may be adapted to allow the longitudinal and transverse movement of the movable part to compensate for rotational movement of pivot mounted linkages connected to first and second ends of the movable part.
