摘要： The invention relates to an ultrasonic actuator, preferably for use in an ultrasonic motor, in the form of a piezoelectric plate with a length L, height H and thickness t, wherein the piezoelectric plate has a lateral plane of symmetry Sq, a longitudinal plane of symmetry Sl and at least two main surfaces, and the piezoelectric plate comprises at least two generators symmetrically disposed with respect to plane of symmetry Sq for generating ultrasonic standing waves. According to the invention, the piezoelectric plate has a shape that includes at least eight lateral surfaces, wherein at least two of the lateral surfaces are working surfaces for contacting of elements to be driven, and at least two of the lateral surfaces are holding surfaces for holding the piezoelectric plate, and the remaining lateral surfaces are free surfaces, wherein at least four free surfaces are arranged at an identical angle α with respect to the longitudinal plane of symmetry Sl and/or at an identical angle φ with respect to the lateral plane of symmetry Sq.

摘要： A piezoelectric motor has a stator module (1), comprising two pairs of piezoelectric actuators (1a, 1b) and (2a, 2b) inside this stator module. The stator module is fixed by a central fixing point (A). The piezoelectric actuators (1a, 1b, 2a, 2b) are connected to the stator module via flexible or biasing elements (3), such as for instance hinges, for instance elastic hinges. The stator module (1) comprises a tuning mechanism (4), comprising at least one mass (4a, 4b) and at least one flexible or biasing element (5a, 5b, 5c, 5d), for instance leaf springs. The stator module (1) is contacted to a driven part (6), for instance a slider, at the contact point (A). The piezoelectric motor is designed such that contact point (B) is able to produce a closed trajectory, thereby inducing a relative motion of the driven part (6). The contact point (B) is moved by applying an electric field to actuators (1a and 1b) and/or by applying an electric field to actuators (2a and 2b).

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.
