# Linear voice coil retractor

## 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.
