<p>The motor (1) has a drive piezoelement (6) producing drive force, and clamping piezoelement (14) producing clamping force at a driven body e.g. driven disk (2) and driven strip. The driven body has flat inner and outer side surfaces (7, 8), which extend parallel to an operative axis (WA) of the drive piezoelement. Contact surface for the clamping force is formed by the side surfaces. The clamping piezoelement is arranged opposite to the contact surface in such a manner that an operative axis (WK) of the clamping piezoelement is aligned perpendicular to the contact surface.</p> |
