摘要： An electromechanical motor (1) has a driving element (20) comprising two electromechanical vibrators (22, 24). The two electromechanical vibrators (22, 24) are interconnected by a link member (26). The electromechanical vibrators (22, 24) are, at the ends (21, 23) connected to the link (26), attached to a backbone (12) of a stator (10) by a respective resilient joint member (14, 16). A mechanical connection to the backbone (12) is thus introduced essentially between the vibrator (22, 24) and the link (26). A vibration of one of the electromechanical vibrators (22, 24) is transferred into a tilting or torsion of one of the joint members (14, 16), and a similar vibration of the other electromechanical vibrator (22, 24) provides a tilting or torsion of the other joint member (14, 16). The link (26), interconnecting the vibrators (22, 24) is subsequently caused to deform and move. Depending on the vibrations and their relative phases, an actuating portion (28) of the link (26) can be brought along a motion path and this can in turn be used to interact with a body to be moved.

摘要： A driving system in accordance with embodiments of the present invention includes a structure and a vibration system. The structure has at least one point to frictional couple to and drive a movable element in one of at least two directions. The structure also has at least two bending modes which each have a different resonant frequency. The vibration system applies two or more vibration signals which are at a vibration frequency to each of the bending modes of the structure. The vibration frequency is substantially the same as one of the resonant frequencies. At the vibration frequency one of the bending modes of the structure is vibrating substantially at resonance and the other of the bending modes of the structure is vibrating at partial resonance. The vibration system adjusts a phase shift between the two or more applied vibration signals to control which one of the at least two directions the moveable element is moved.

Then, a plurality of piezoelectric layers (26) are formed in the drive sections respectively by depositing particles of a piezoelectric material onto the plate-shaped member. Subsequently, after forming individual electrodes (27) on the piezoelectric layers respectively, the drive sections are bent in a direction orthogonal to a plane direction of the plate-shaped member. Thus, there is provided a method of easily producing a piezoelectric actuator including the drive sections which are bent-shaped and on which the piezoelectric layers are formed respectively.

摘要： In a method and a device (100) according to the present invention, two piezo-elements (10, 20) are driven with two voltages having a phase difference. One of the piezo-elements (10, 20) is charged by an inductive step-up means (73, 74) to a voltage exceeding an available power supply voltage (VS). Subsequently charge, i.e. energy is transferred from said one piezo-element (10, 20) to the other piezo-element (20, 10) by an inductive element (LA, LB). The same inductive element (LA, LB) is used in an inductive step-up means (73, 74) and in the transfer of the charge between said two piezo-elements (10, 20).

摘要： In an electromechanical motor (10), elongated electromechanical drive elements (30) are mechanically and preferably also electrically attached to a carrier (150). A spring (54) is arranged to apply a force on the electromechanical drive element (30) by pressing the backside of the carrier (150) at a pivot point (152). The carrier (150) is allowed to pivot around the pivot point (152) around an axis parallel to the element elongation. The electromechanical drive element (30) is thereby suspended in a floating manner. The electromechanical drive elements (30) are arranged to present a bending motion having strokes perpendicular to the elongation. The pivot point (152), the mechanical joint (151) between the carrier (150) and the electromechanical drive element (30), and preferably also a nodal point (155) of bending motions of the electromechanical element (30) are situated at a common plane perpendicular to the element elongation. In one embodiment, the electromechanical drive element is provided with metallisations (32) to which the carrier (150) is soldered. These metallisations (32) are provided at the longitudinal sides of the electromechanical drive element (30). The metallised areas are soldered or fastened by other means, e.g. by gluing, to attachment pads of a flexible printed circuit board, preferably by using surface mounting techniques.
