Abstract
A manufacturing method for an electromechanical drive element comprises providing (S) 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 (S). 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 (S) 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.
