Abstract
A linear piezoelectric motor and a slider drive system thereof are disclosed. The linear piezoelectric motor includes a piezoelectric ceramic element and a base structure. The piezoelectric ceramic element includes a first region, a second region and an interval region located between the first and the second region, wherein the first and the second region may be formed by a first and a second power signal supplied by a power supply to form a first and a second standing wave, respectively. The interval region is a quarter wavelengths. The first and the second standing wave have a phase difference so as to form a traveling wave. The base structure disposes the piezoelectric ceramic element and has a pectinate structure to increase the amplitude of the first and the second standing wave, thereby enabling the piezoelectric motor to be driven.
