Abstract
An actuator for precisely moving and positioning a manufacturing component includes a housing on which a magnet is mounted. An electrical coil is wound around a coil piston which 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 movement with the coil piston, and a source of electrical current is connected to the coil which is wrapped around the coil piston. In the operation of the actuator, a current is selectively passed through the coil. This current in the coil then moves the coil piston and the attached grip within the magnetic field to position the component as desired. Additionally, a position sensor can be mounted on the device to determine the location of the coil piston and a controller can be incorporated in the actuator to use this position determination for controlling movement of the coil piston and the attached grip.
