Abstract

A solid-state actuator drive apparatus has—a shaft, —a pivot bearing for supporting the shaft, —a drive body, —at least two actuators for the excitation of the drive body and the shaft relative to each other for causing the shaft to rotate relative to the drive body, and—a base element, on which these components are attached. Either the drive body is configured such that it has a drive body opening, and the shaft at least leads into the drive body opening, —or the shaft is configured as a hollow shaft, and an element of the drive body having an annular or discoid circumference is disposed therein. The drive body is disposed stationary relative to the base element. The shaft is disposed in the pivot bearing and is adjustably disposed in the radial direction of the shaft relative to the base element by the solid-state actuators.
