Abstract: A manufacturing method for an electromechanical drive element comprises providing (S10) of an excitation body comprising at least one volume of electromechanical material. The excitation body has a metal plate integrated as a surface of the excitation body. The excitation body being arranged to cause shape changes of the electromechanical material and the metal plate when the volume(s) of electromechanical material being excited by a voltage signal. A composite drive pad is provided (S20). The composite drive pad comprises a metal portion directly joined to a ceramic portion. After the providing of a composite drive pad, the metal portion of the composite drive pad is irreversibly attached (S30) to the metal plate of the excitation body by use of a metal-based bond. An electromechanical drive element and an electromechanical motor using such an electromechanical drive element are also disclosed.

Abstract: An electromechanical motor (1) comprises a stator (2) and a translator (10). The stator has two electromechanical actuators (20) having electromechanically active material (26) and means (35) for providing exciting signals. The translator is arranged between, and in driving contact with, driving portions (22) of the electromechanical actuators. The stator has a spring element (30) arranged for holding the driving portions against the translator. The electromechanical actuators are arranged for providing a vibration, which gives rise to a driving action, directed in a driving direction (X) perpendicular to the direction of the normal force, against the surface of the translator. The electromechanical motor further comprises a guiding means (50) having a circular hole (52). The translator has a cylindrically shaped guidance part (16) arranged at least partly in the circular hole. A tunable high-frequency filter comprising such a motor is also disclosed.
