Abstract:
1. A piezo motor, comprising: a stator; a rotor; and at least one drive finger which is held by the stator, drives the rotor and interacts with at least one piezo element, wherein the drive finger moves, with a free end of the drive finger, a driver jaw which can be pressed against an annular face of the rotor, wherein the free end of the drive finger is held in a radially displaceable fashion between two stops of the driver jaw, and wherein, during a drive movement of the drive finger, the driver jaw can be pressed against the rotor by at least one piezo actuator in time with the drive movement of the drive finger, and can be pivoted in the drive direction and back about a rotor axis, together with the piezo actuator, in accordance with a magnitude of a deflection of the drive finger.
