摘要: An electromechanical actuator (300) includes an oscillation resonator (210) having the shape of a rod. The oscillation resonator is rotatable with respect to a base part (220). Thereby, a self-alignment between the oscillation resonator, friction surfaces (230, 251) and slider (250) or a rotator is obtained. As a result thereof, unevenness of wear is reduced and the actuator's lifetime is extended.

摘要: An electromechanical actuator (100) includes an oscillation resonator (10) having the shape of a rod. The oscillation resonator (10) is divided by a dividing plane (15) that is not parallel to the longitudinal direction of the oscillation resonator (10) into a first resonator portion (10A) and a second resonator portion (10B). At least the first resonator portion includes electromechanical means which, when activated, are configured to generate a 3-dimensional acoustic bulk wave are with a mode shape asymmetric with respect to the dividing plane (15).
