An electromechanical motor ( 1 ), using at least two bimorph, monomorph or multimorph electromechanical actuating elements ( 6 ) interconnected by a common actuator backbone ( 5 ) is disclosed. The actuating elements ( 6 ) are controllable in both a longitudinal direction (L), i.e. in the main extension direction of the actuating element ( 6 ), and a flexural direction, i.e. bending of the actuating element ( 6 ), separately. The different actuating elements ( 6 ) can be controlled individually as well. The actuator ( 3 ) dimensions are preferably selected to resonance frequencies in vicinity of a certain frequency. The actuating elements ( 6 ) are provided with interaction portions ( 7 ) at which any contact between the actuator and a body ( 2 ) to be moved is made. In order to operate well both in fine-positioning and resonant motion, the interaction portions ( 7 ) are arranged to partially suppress the transfer of acoustic waves between the actuating elements ( 6 ) and the body ( 2 ) to be moved.
