Abstract
A piezoelectric motor for moving and positioning a load, the motor comprising: a piezoelectric vibrator having a plurality of electrodes and a coupling surface which is pressed to a load; and a power supply selectively operable to electrify at least one vibrator electrode with time varying voltage to generate vibrations in the coupling surface that step the load to a desired position or to electrify at least one vibrator electrode with DC voltage to displace the coupling surface and move thereby the load to a desired position, which DC voltage the power supply maintains to maintain the load at the desired position.
