Abstract
An electromechanical motor () has a driving element () comprising two electromechanical vibrators (). The two electromechanical vibrators () are interconnected by a link member (). The electromechanical vibrators () are, at the ends () connected to the link (), attached to a backbone () of a stator () by a respective resilient joint member (). A mechanical connection to the backbone () is thus introduced essentially between the vibrator () and the link (). A vibration of one of the electromechanical vibrators () is transferred into a tilting or torsion of one of the joint members (), and a similar vibration of the other electromechanical vibrator () provides a tilting or torsion of the other joint member (). The liner (), interconnecting the vibrators () is subsequently caused to deform and move. Depending on the vibrations and their relative phases, an actuating portion () of the link () can be brought along a motion path and this can in turn be used to interact with a body to be moved.
