ABSTRACT:
In an electromechanical motor, elongated electromechanical drive elements are mechanically and preferably also electrically attached to a carrier. A spring is arranged to apply a force on the electromechanical drive element by pressing the backside of the carrier at a pivot point. The carrier is allowed to pivot around the pivot point around an axis parallel to a the element elongation. The electromechanical drive element is thereby suspended in a floating manner. The electromechanical drive elements are arranged to present a bending motion having strokes perpendicular to the elongation. The pivot point, the mechanical joint between the carrier and the electromechanical drive element, and preferably also a nodal point of bending motions of the electromechanical element are situated at a common plane perpendicular to the element elongation. In one embodiment, the electromechanical drive element is provided with metallizations to which the carrier is soldered.
