ABSTRACT:
An ultrasonic linear motor includes a substrate; a vibrator disposed on the substrate having an oblique or curved face at two sides thereof forming concave receiving portions with the surfaces of the substrate; and a slider having clamping portions at two sides thereof for correspondingly clamping to the receiving portions, wherein the vibrator is for generating a driving force to the slider while connecting with a power supply, such that the clamping portions of the slider move within the receiving portions, thereby generating a linear translation. The present invention adopts a simple structure having few elements that enables easy manufacturing and integration with other elements, thus reducing manufacturing cost.
