Abstract
An electromechanical motor () has a driving element () comprising two electromechanical sections () extended substantially parallel to a driving surface () of a body () to be moved. The electromechanical sections () are rigidly supported by a backbone portion () of a stator () at a first end (). An link member () having a single actuating portion (), which by its interaction with the driving surface () of the body () moves the body (), is attached between respective second ends () of the electromechanical sections (). The electromechanical sections () are excitable in a vibration mode having strokes substantially perpendicular to the direction of motion (). A portion of the link () or the joints () between the link member () and the electromechanical sections () have a bending stiffness in the direction of the strokes that is significantly lower than the bending stiffness of the electromechanical sections () themselves.
