Patent ID: 7923901

Claim:
A solid-state actuator drive apparatus comprising: a shaft having a shaft axis; a pivot bearing for supporting the shaft so that the shaft can rotate; a drive body; at least two actuators to excite the drive body and the shaft relative to one other to cause the shaft to rotate relative to the drive body; and a base element, on which the shaft, the pivot bearing, the drive body and the actuators are fixed, wherein either the drive body has a drive body opening and the shaft feeds into the drive body opening or the shaft is a hollow shaft, the drive body has an annular or discoid circumference and is disposed in the hollow shaft, the drive body is stationary relative to the base element, and the shaft is positioned in the pivot bearing so that the actuators can change a position of the shaft relative to the base element in a plane perpendicular to the shaft axis of the shaft.
