Abstract
A piezoelectric motor includes a rotating body, a piezoelectric actuator including a protruding section having contact with the rotating body, and adapted to rotate the rotating body due to a motion of the protruding section when driving a piezoelectric element, and a drive circuit adapted to drive the piezoelectric element, and the drive circuit includes a drive signal generation section adapted to output a drive signal with a predetermined frequency, and an LC filter adapted to block a frequency higher than the predetermined frequency, and applies the drive signal to the piezoelectric element via the LC filter.
