摘要： A piezoelectric motor has a stator module 1, comprising two pairs of piezoelectric actuators Ia, Ib 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 Ia and Ib and/or by applying an electric field to actuators 2a and 2b.
