ABSTRACT

An actuator for precisely moving and positioning a manufacturing component
includes a housing on which a magnet is mounted. An electromagnetic is
slidingly mounted on the housing for movement within the magnetic field
generated by the magnet. A rod, having a member for gripping the component, is
attached for translational movement with the electromagnetic coil. In the
operation of the actuator, a current is selectively applied to the
electromagnetic coil. The current in the coil creates a magnetic field that
moves the electromagnetic coil and the attached grip within the magnetic field
to position the component as desired in translation. A retractor causes the
grip to preferentially adopt a predetermined position, or dwell configuration.
