Abstract

Piezoelectric drive (10) and method of operating same to move movable parts (11), in particular in a motor vehicle. The drive (10) has at least one piezoelectric motor (12) with at least one piezo-actuator (18). At least one friction element (30) of the piezoelectric motor (12) can generate a relative movement relative to a friction surface (14) opposite the friction element (30). The at least one piezo-actuator (18) is connected to an electronic unit (42) having an electric tuning circuit (46) that tunes the piezoelectric drive (10) to a resonance frequency (44).
