摘要:
A piezoelectric motor (1) is proposed which comprises at least two piezoelectric actuators (2), each piezoelectric actuator comprising at least two piezoelectric elements (3) arranged at opposite sides of a coupling element (4, 11) and having two oppositely arranged large main surfaces (5) connected to each other by at least four side surfaces (6). The piezoelectric actuators are spaced from each other but coupled via at least one elastic element (7) intended for direct or indirect frictional contact with an element to be driven. The at least one elastic element (7) is attached to at least a part of a side surface (6) of the piezoelectric actuators thus bridging the space (8) between them. The piezoelectric actuators deform in a direction substantially perpendicular to a plane (9) defined by the side surface to which the elastic element (7) is attached by using the longitudinal piezoelectric effect of the elements.
