The invention relates to a piezoelectric motor (1), comprising an inner piece (2), surrounded by an outer piece (3). The inner piece (2) comprises at least one piezo element (9), which co-operates with a vibration element (5). The vibration element (5) comprises a middle piece (6) around which at least one arm (7, 15) is arranged. The arm (15) co-operates with the outer piece (3) in an interaction region (16) and is embodied such that the above is set in vibration by the at least one piezo element (9) and drives the outer piece (3) relative to the inner piece (2). |
