Abstract

PURPOSE:To provide location control with simplified structure, quick responsive speed and high accuracy by providing a movable table on the upper surface of a vibrator of a stator having an electro-magneto striction elements bonded fixedly and provided one or both of directions of axes X, Y to frictionally contact said upper surface. CONSTITUTION:When a supersonic signal is applied from a high frequency power source 3 to an electro striction element 2, elements 2a, 2b arrnanged longitudinally of the electro striction element 2 are different in the direction of polarization and provided to be respectively logitudinally extended and contracted, and defective vibrations like 2c are generated on the vibrator 1. These vibrations are propagated from left to right so that a mover 4 is driven in the opposite direction to wave motion by a frictional force to the vibrator 1 to operate as a linear motor. Thus, the mover 4 can be directly driven so that a feeding mechanism can be simplified and the location control with high responsive speed and accuracy can be achieved by dirrect drive without any back-lash or such.
