Abstract
An electromechanical motor () comprises a stator () and a translator (). The stator has two electromechanical actuators () having electromechanically active material () and means () for providing exciting signals. The translator is arranged between, and in driving contact with, driving portions () of the electromechanical actuators. The stator has a spring element () arranged for holding the driving portions against the translator. The electromechanical actuators are arranged for providing a vibration, which gives rise to a driving action, directed in a driving direction (X) perpendicular to the direction of the normal force, against the surface of the translator. The electromechanical motor further comprises a guiding means () having a circular hole (). The translator has a cylindrically shaped guidance part () arranged at least partly in the circular hole. A tunable high-frequency filter comprising such a motor is also disclosed.
