  • Publication number: 20140210311
    Abstract: An electromechanical motor (1) comprises an object (2) to be moved, a vibrator beam (10), at least two protruding portions (12) attached to the vibrator beam, a normal force providing arrangement (40) applying a normal force (F) between the object and actuating ends (11) of the protruding portions for interaction with the object. The vibrator beam has vibrator beam electrodes (18A, 18B) for exciting at least one vibrator beam active volume (14) of electromechanically active material, enabling bending the vibrator beam perpendicular to a main extension direction of the vibrator beam and along the protruding portions (12). Control electronics (50), connected to the vibrator beam electrodes, is configured for providing resonance electrical signals causing the vibrator beam active volume to induce a resonant bending vibration and is further configured for providing quasi-static electrical signals causing a quasi-static motion of the actuating ends, superimposed on motion caused by the resonant bending vibration.
