Beschreibung
Zusammenfassung:	The disclosed piezoelectric motor (11) comprises two actuator assemblies and a frame (12). The first actuator assembly comprises a first piezoelectric actuator (10a) and two rollers (32a, 34a), each of the rollers pressed between the first piezoelectric actuator and a first frame side, and the second actuator assembly comprises a second piezoelectric actuator (10b) and two rollers (32b, 34b), each of the rollers pressed between the second piezoelectric actuator and a second frame side. The motor further comprises at least one pre-loaded spring (36, 38) provided between the first actuator assembly and the second actuator assembly, pushing the first actuator assembly against the first frame side and the second actuator assembly against the second frame side.
