Abstract
A linear motion micropositioning device employs a housing containing fixed, electrically excited stators. A rotating permanent magnet rotor is directly attached to a spindle of a precision lead screw. The stators are provided with sufficient axial depth to permit the rotor to rotate and reciprocate axially while under continuous magnetic influence of the stators.
